AREA FORECAST DISCUSSION
NWS GRAND RAPIDS MI
1048 AM EDT SAT JUN 2 2007
.UPDATED...
I LOWERED THE POP THIS AFTERNOON OVER ALL OF THE CWA TO CHC SINCE I
DO NOT SEE ANY REAL MECHANISM FOR THUNDERSTORM GENERATION OTHER THEN
THE LAKE BREEZE BOUNDARY INTRACTION. TRUE...THERE ARE DECENT CAPES
AND THE SURFACED BASED LI VALUES WILL BE NEGATIVE OVER JUST ABOUT
ALL OF THE CWA. EVEN SO...THE DNVA BEHIND THE EARLY MORNING
CONVECTION SHOULD SUPPRESS CONVECTION INTO MID AFTERNOON. MEANWHILE
SHORTWAVE ENERGY NEAR CHI AT 15Z MAY AID LAKE BREEZE CONVECTION NEAR
US-131 BY MID AFTERNOON. DUE TO THE LAKE BREEZE INTERACTION WITH
THE SHORTWAVE THIS AFTERNOON I DO HAVE LIKELY POP NEAR US-131 BY
MID AFTERNOON. THAT CONVECTION WILL LIKELY MOVE INLAND THIS EVENING
BEFORE WEAKENING WITH THE LOSS OF SOLAR ENERGY. THUS I KEEP THE
NUMEROUS WORDING EARLY EVENING HOURS FOR THUNDERSTORMS.
AS FOR SEVERE THUNDERSTORMS...CAPES ARE IMPRESSIVE BUT THE WIND
FIELD THROUGH MID LEVELS IN NOT CONDUCIVE TO SEVERE WEATHER.
FREEZING LEVELS ON TAMDAR AT 12-14Z ARE SLOPE UP FROM 12000 FT NEAR
JXN TO 1300 FT NEAR THE LAKE MICHIGAN SHORE. THE HIGH FREEZING
LEVELS AT FIRST GLANCE WOULD NOT SUPPORT HAIL. HOWEVER...MODEL
FORECAST SOUNDING SUGGEST PULSE LARGE HAIL IS NOT OUT OF THE
QUESTION SINCE BASED ON THE RUC MODEL SOUNDINGS THERE IS A FAIR
AMOUNT OF CAPE ABOVE THE -10C LEVEL. THE NAM IS MORE CONSERVATIVE.
THE BIG QUESTION IS WILL THE LOW LEVEL DEW POINTS LOWER THIS
AFTERNOON AS DEEPER MIXING OCCURS. IF SO ALL BETS OF OFF FOR ANY
SEVERE WEATHER OVER THE GRR CWA TODAY OR TONIGHT.
THE REST OF THE ZONE FORECAST SEEMS TO BE ON TRACK... SO THAT
REMAINS AS IS.
.PREVIOUS DISCUSSION...
WV IMAGERY THIS MORNING SHOWS THE UPPER LOW CONTINUING TO SPIN OVER
THE PLAINS STATES EARLY THIS MORNING. THE LOW IS CURRENTLY CENTERED
OVER THE ERN BORDER OF SOUTH DAKOTA AND NEBRASKA. AHEAD OF THE UPPER
LOW IS A NICE BELT OF DEEP SW FLOW WITH EMBEDDED SHORT WAVES RIDING
TO THE NE. OUR MAIN CONCERN IN THE SHORT TERM PORTION OF THE
FORECAST IS PCPN CHCS AND SEVERE POTENTIAL FROM TODAY RIGHT ON
THROUGH MON AS THE UPPER LOW MOVES TOWARD THE AREA THROUGH SUN AND
IS THEN RIGHT OVERHEAD LATE SUN INTO MON.
REMNANTS OF THE LINE OF CONVECTION THAT AFFECTED AREAS TO OUR WEST
OVER IA/IL/WI DURING THE DAY ON FRI...ARE CURRENTLY MOVING THROUGH
THE CWFA THIS MORNING. THE CONVECTION HAS DIMINISHED SIGNIFICANTLY...
HOWEVER DUE TO MESOSCALE EFFECTS AND AN INSTABILITY AXIS ALOFT...
SOME OF THE CONVECTION HAS MAINTAINED ITSELF AS IT MOVES NE. THIS
BATCH OF CONVECTION WILL MOVE EAST OF THE CWFA BY 12Z...LEAVING THE
AREA IN A RELATIVE VOID OF MOST PCPN TEMPORARILY. CLOUDS SHOULD BE
SOMEWHAT LIMITED THIS MORNING WITH DEBRIS FROM UPSTREAM CONVECTION
RESPONSIBLE MOST CLOUD COVER INITIALLY. BREAKS IN THE CLOUDS MAY
ALLOW FOR SOME FOG TO DEVELOP WITH THE HIGHER DEW POINTS IN
PLACE...ESPECIALLY AT LOCATIONS THAT HAVE SEEN SOME RAIN THIS
MORNING.
AFTER ANY FOG DISSIPATES...SOME SUN WILL HELP WARM TEMPS BACK INTO
THE 80S ACROSS MOST OF THE CWFA. SUN WILL BE SOMEWHAT LIMITED AFTER
THE MORNING AS ADDITIONAL DEBRIS CLOUD COVER FROM CONVECTION SW OF
THE AREA WILL STREAM INTO THE AREA. ADDITIONAL WAVES THAT CAN BE
SEEN FROM LOWER MICHIGAN BACK DOWN INTO THE MO AREA WILL TEND TO
MOVE TOWARD THE AREA THIS MORNING. HOW MUCH WE DESTABILIZE OBVIOUSLY
HAS TO DO WITH HOW MUCH SUN WE CAN GET...AND THIS DEPENDS ON THE
TIMING OVER UPSTREAM SHORT WAVES. ASSUMING WE CAN GET A FAIR AMOUNT
OF SUN THIS MORNING...MODIFIED FCST SOUNDINGS FOR THIS AFTERNOON
WITH TEMPS IN THE MID 80S AND DEW POINTS IN THE LOW TO MID 60S WOULD
SUPPORT SB CAPES AROUND 2000 J/KG AND SB LI/S AROUND -5. WITH SHORT
WAVES EXPECTED TO BEGIN MOVING ACROSS THE AREA LATER TODAY AS THE
UPPER LOW APPROACHES THE AREA...THIS SUPPORTS A BETTER THREAT OF
CONVECTION THAN WHAT HAS BEEN PRESENT THE PAST FEW DAYS. DEEP LAYER
SHEAR ON A SYNOPTIC SCALE IS NOT VERY IMPRESSIVE FOR MOST OF THE DAY
AS MID LEVEL WINDS ARE ONLY 25 TO 30 KTS GIVING SHEAR VALUES OF
20 KTS OR SO. DEEP LAYER SHEAR DOES INCREASE LATE FROM THE NW AS THE
MID LEVEL JET MOVES IN. ALSO IF ANY CONVECTIVELY INDUCED VORT MOVES
IN...THERE WOULD BE SOME GOOD LOCALIZED SHEAR PRESENT. POTENTIAL
INSTABILITY COULD MAKE UP FOR THIS AND PRODUCE A WIND AND HAIL
THREAT...ESPECIALLY LATER AS THE SHEAR INCREASES. WE HAVE INCREASED
THE POPS IN THE AFTERNOON AND EVENING HOURS TO THE LIKELY/NUMEROUS
CATEGORY.
WITH THE LOSS OF DIURNAL INSTABILITY...THE THREAT OF WIDESPREAD
STORMS AND SEVERE WEATHER WILL DIMINISH BY THE OVERNIGHT HOURS. THE
THREAT OF SHOWERS AND STORMS WILL REMAIN THOUGH WITH THE AREA
REMAINING PRONE TO SHORT WAVES RIDING NE ALONG THE MID LEVEL FLOW.
WE HAVE TRENDED POPS LOWER FOR THE SECOND HALF OF THE NIGHT TONIGHT.
THE UPPER LOW WILL THEN FINALLY MOVE NEARBY DURING THE COURSE OF THE
DAY ON SUN ALONG WITH THE ASSOCIATED SFC FRONT. A FEW PEEKS OF SUN
WILL BE POSSIBLE SUN MORNING...BUT WITH THE COLD POOL ALOFT MOVING
OVERHEAD AND PLENTY OF LOW LEVEL MOISTURE...BREAKS IN THE CLOUDS
WILL FILL IN AND SHOWERS AND STORMS WILL BEGIN DEVELOPING.
INSTABILITY WILL NOT BE AS FAVORABLE AS SFC TEMPS WILL ONLY RISE
INTO THE 70S. HOWEVER DEW POINTS STILL IN THE 50S AND LOWER 60S WILL
ACT WITH COLD POOL ALOFT TO PROVIDE AROUND 1000 J/KG OF SB CAPE AND
LI/S AROUND -3. DEEP LAYER SHEAR WILL BE MUCH BETTER WITH THE MID
LEVEL JET MOVING OVERHEAD DURING THE DAY. SEVERE HAIL WILL BE
POSSIBLE DUE TO FREEZING LEVELS OF ONLY AROUND 9K TO 10K FEET...AND
SOME DOWNBURSTS WILL BE POSSIBLE WITH THE BETTER ORGANIZED STORMS.
THE POTENTIAL OF PCPN WILL THEN DIMINISH SOMEWHAT ON MON AS THE
UPPER LOW FINALLY OPENS UP INTO A WAVE AND THE BETTER MOISTURE MOVES
EAST OF THE AREA. A FEW INSTABILITY SHOWERS WILL BE POSSIBLE MON
AFTERNOON. THUNDER WILL REMAIN POSSIBLE AS THE COLD POOL ALOFT
REMAINS OVERHEAD AND LI/S REMAIN SLIGHTLY NEGATIVE. TEMPS ON MON
WILL LIKELY ONLY WARM INTO THE MID 60S TO LOWER 70S WITH THE THERMAL
TROUGH MOVING IN.
.LONG TERM...
MON THROUGH FRI...MID AND UPPER LEVEL CYCLONIC FLOW CONTINUES
THROUGH TUE WITH BUILDING HEIGHTS LATE ON TUE INTO THU AS WRN RIDGE
BUILD EWD. ON TUE LATEST GFS/ECMWF SHOWING WEAK S/W ENERGY MOVING
THROUGH TROF...SO THINKING IS FOR SCT SHOWER THREAT ESPECIALLY WITH
AFTN DIURNAL HEAT MAX. TEMPS WILL START OUT BELOW NORMAL AND TREND
UPWARDS TOWARDS THU.
BY THU EARLY AM WARM FRONT PUSHES INTO AREA WITH S/W ENERGY DIGGING
ESE AS IT TOPS RIDGE AXIS ALOFT. THIS WOULD BE A GOOD SCENARIO FOR
EARLY MORNING MCS EVENT. BUMPED POPS A FEW PERCENT TO START A TREND
TOWARDS POTENTIAL EVENT.

NWS DETROIT/PONTIAC MI
101 AM EDT SAT JUN 2 2007
.AVIATION...
AMPLE LOW LEVEL MOISTURE WILL LEAD TO MOSTLY MVFR VISIBILITIES IN
HAZE/FOG THROUGH AT LEAST 16Z BEFORE INCREASING SOUTHWESTERLY WINDS
ADD A LITTLE MIXING TO THE BOUNDARY LAYER. AT THIS TIME...WILL KEEP
SHOWERS AND THUNDERSTORMS OUT OF THE TAFS UNTIL LATE AFTERNOON/EARLY
EVENING. CONDITIONS LOOK A LITTLE MORE CONDUCIVE TO THUNDERSTORM
DEVELOPMENT SAT AFTERNOON IN COMPARISON TO THE LAST TWO DAYS DUE TO
HIGHER INSTABILITY AND A WEAKER MID LEVEL CAPPING INVERSION.
&&
.PREV DISCUSSION...ISSUED 957 PM EDT FRI JUN 1 2007
UPDATE...
THE KDTX RADAR SHOW ONLY A COUPLE LINGERING SHOWERS ACROSS SE MI.
THE 00Z DTX SOUNDING SHOWS A CAPPING INVERSION NEAR 600MB...WHICH
HAS PREVENTED THUNDERSTORM DEVELOPMENT OVER SE MI THIS AFTERNOON
AND EVENING. AN AREA OF THUNDERSTORMS...CURRENTLY MOVING ACROSS
WESTERN LAKE MICHIGAN IS ASSOCIATED WITH A MID LEVEL SHORT WAVE
OVER EASTERN WISCONSIN. THIS WAVE IS FORECAST TO LIFT NORTH-
NORTHEAST TONIGHT...WITH THE CONVECTION OVER LAKE MICHIGAN
FORECAST TO WEAKEN AS IT MOVES INTO A LESS FAVORABLE ENVIRONMENT.
THE WATER VAPOR LOOP DOES SHOW A POCKET OF MID LEVEL DRY AIR OVER
SE MI...WITH THE LEADING EDGE OF DEEPER MOISTURE NOW MOVING ACROSS
SW LOWER MI. THIS SUPPORTS LATEST MODEL GUIDANCE WHICH SHOWS AN
AXIS OF MOISTURE CONVERGENCE BETWEEN 925MB AND 850MB WORKING
ACROSS SE MI BETWEEN 06Z AND 12Z. THIS SEEMS TO WARRANT HOLDING
ONTO ISOLATED SHOWERS IN THE FORECAST THROUGH THE NIGHT AND INTO
EARLY SAT MORNING. MODEL SOLUTIONS ALSO HINT AT SOME MID LEVEL
COOLING TOWARD 12Z...WHICH MAY STILL PROVIDE A CHANCE FOR ISOLATED
THUNDERSTORMS BY EARLY MORNING. WILL ISSUE AN UPDATE TO CARRY
ISOLATED SHOWERS ACROSS THE ENTIRE FORECAST AREA THROUGH THE
NIGHT. ALSO...WITH SURFACE DEWPOINTS IN THE LOWER 60S AND GIVEN
CURRENT TEMPERATURE TRENDS...HAVE INCREASED OVERNIGHT MINS A
COUPLE DEGREES.
PREV DISCUSSION...ISSUED 409 PM EDT FRI JUN 1 2007
SHORT TERM...REST OF TODAY AND TONIGHT
ALL THAT IS LEFT OF MORNING CLOUDS IS A THIN CIRRUS SHIELD THAT WILL
VACATE THE PREMISES THE NEXT FEW HOURS. IN TOW OF THE MORNING
ACTIVITY...DIURNAL CUMULUS HAS DEVELOPED IN EARNEST WITH ABUNDANT
BOUNDARY LAYER MOISTURE. THE FORECAST CHALLENGE REMAINS ON
THUNDERSTORM DEVELOPMENT THIS AFTERNOON AND EVENING. AS HAS BEEN
SEEN THE PAST FEW DAYS ANY FOCUS FOR ISOLATED/SLIGHT CHANCE OF
THUNDERSTORMS WILL BE TIED TO THE LAKE BREEZE AND ANY OUTFLOW
BOUNDARIES. WHAT IS DIFFERENT TODAY THOUGH IS AN OLD WASHED OUT
/OCCLUDED FRONT THAT HAS MADE ITS WAY INTO CENTRAL MICHIGAN FROM THE
LARGE EYE CATCHING UPPER LEVEL VORTEX CENTERED OVER DEWEY COUNTY
SOUTH DAKOTA. CELLS HAVE BEEN TRYING TO DEVELOP...TO NO
AVAIL...ALONG THIS BOUNDARY FROM SHIAWASSEE...SAGINAW...TUSCOLA
COUNTIES. TWO AGREEABLE TAMDAR SOUNDINGS HAVE GIVEN GOOD CONFIDENCE
OF A CAPPING ENVIRONMENT...ROUGHLY 875-800 MB ACROSS SOUTHEASTERN
MICHIGAN. THIS SHOULD REMAIN THE CASE FOR DEWPOINTS THAT REMAIN IN
THE LOW 60S. ELEVATED INSTABILITY DOES EXIST BUT WITH A MAX WIND OF
20 KNOTS IN THE ATMOSPHERIC COLUMN AND NOTHING IN THE WAY OF A LOW
LEVEL JET...HARD TO FIND ANY FORCING/SUPPORT TO REALIZE THE
INSTABILITY. AS A RESULT HAVE BACKED DOWN ON ISOLATED SHOWER AND
THUNDERSTORM MENTION TO THAT OF SLIGHT CHANCE. WITH WEAK 0-6KM BULK
SHEAR OF LESS THAN 20 KNOTS AND MIXED LAYER CAPE VALUES OF LESS THAN
1000 J/KG SEVERE POTENTIAL OF ANY DEVELOPMENT WILL BE MINIMAL.
OVERNIGHT...COMPLEX CURRENTLY FIRING ACROSS EASTERN IOWA/WESTERN
ILLINOIS WILL CONTINUE LIFTING NORTHWARD AROUND THE NORTHERN PLAINS
VORTEX. THIS WILL KEEP GREATEST MOISTURE AND PRECIPITATION CHANCES
ACROSS LAKE MICHIGAN AND THE FAR WESTERN LOWER PENINSULA TOWARDS
DAYBREAK. A LOW LEVEL JET MAX PUSHING 30 KNOTS WILL HELP FEED THIS
DEVELOPMENT THROUGHOUT THE NIGHT. WILL KEEP A SLIGHT CHANCE OF
THUNDERSTORMS OVERNIGHT FOR THE FAR WESTERN CWA AS A BUFFER TO
SURROUNDING CWA/S BUT FEEL MOST AREAS WILL REMAIN DRY PRIOR TO THE
ENDING OF THIS FORECAST PERIOD. CLOUD COVER IS EXPECTED TO WANE WITH
LOSS OF DAYTIME HEATING BUT INCREASE AGAIN AS IA/IL ACTIVITY PUSHES
EASTWARD. WITH THE RELATIVELY HIGH DEWPOINTS AND INSULATING CLOUD
COVER WILL LEAVE MINS IN THE 60S FOR MOST AREAS...MID 60S IN THE
DETROIT HEAT ISLAND.
LONG TERM...SATURDAY THROUGH FRIDAY
ON SATURDAY...FORECAST SOUNDINGS ACROSS THE SOUTH HALF OF THE CWA
LOOK VERY MUCH LIKE SOUNDINGS OBSERVED THROUGHOUT THIS PREVIOUS
WEEK. OVERALL NOT THAT MOIST...WEAK OVERALL DYNAMICS (VERY MINOR
SHORTWAVE ENERGY, NO UPPER LEVEL JET, VERY UNIMPRESSIVE LOW LEVEL
WIND FIELDS)...AND LESS THAN STELLAR FORCING WITH NO LOW LEVEL
CONVERGENCE/UPPER LEVEL DIVERGENCE. UPPER LEVEL CLOUDS COUPLED WITH
A SCATTERED TO BROKEN DECK AROUND 7K FEET SHOULD FILTER PLENTY OF
SUNSHINE...THUS LIMITING OVERALL INSTABILITY. BUT STILL SHOULD BE
ABLE TO REALIZE CAPES BETWEEN 1000-1500 J/KG...SO WOULDN`T EXPECT A
LOT OF CONVECTIVE ACTIVITY ACROSS THIS AREA. NOW FARTHER NORTH...THE
STORY IS MUCH DIFFERENT. BETTER MID TO UPPER SHORTWAVE ENERGY...GOOD
UPPER LEVEL DIVERGENCE...AND DECENT LOW LEVEL CONVERGENCE ALL POINT
TO A BETTER CHANCE OF SHOWERS AND THUNDERSTORMS FROM FLINT AND
NORTH. WITH FAR MORE MOISTURE ACROSS THAT AREA (ESPECIALLY IN THE
BOUNDARY LAYER), CAPES WILL HIT 2000 J/KG. VERY WEAK WIND FIELDS ARE
NOT SUPPORTIVE OF ORGANIZED ACTIVITY...BUT WITH LOWERING FREEZING
LEVELS...THERE DOES EXIST AN OUTSIDE CHANCE OF MARGINALLY SEVERE
HAIL. PW`S AROUND 1.5 AND SLOW STORM MOVEMENT WILL LEAD TO HEAVY
RAIN IN THUNDERSTORMS. BUT GIVEN THE LACK OF RUN TO RUN CONTINUITY
AND THE FACT THAT THE NAM IS NOT NEARLY AS ROBUST AS THE
GFS...SCATTERED SHOWERS AND THUNDERSTORMS LOOKS LIKE THE WAY TO GO
AND THE PREVIOUS FORECAST HAS IT COVERED.
DYNAMICS/MOISTURE WILL ONCE AGAIN BE ON THE RISE ON
SUNDAY...STARTING JUST AFTER MIDNIGHT AS SURFACE LOW AND UPPER LEVEL
DYNAMICS APPROACH FROM THE WEST. THE BIGGEST CHALLENGE FOR THE
SUNDAY FORECAST REVOLVES AROUND THE EVOLUTION OF THE UPPER LOW
MOVING NORTHEAST UP THE EAST COAST AND THE DEGREE OF CYCLOGENESIS
THAT TAKES PLACE JUST OFF THE ATLANTIC SEABOARD. THE PREVIOUS RUN OF
THE NAM WAS MUCH WEAKER AND WAY FARTHER WEST WITH THIS
SYSTEM...GIVING CREDENCE TO MORE PHASING WITH THE UPPER LOW MOVING
ACROSS THE GREAT LAKES ON SUNDAY. BUT THE LATEST RUN OF THE NAM HAS
TRENDED IN THE DIRECTION OF THE GFS IN KEEPING THESE 2 SYSTEMS
SEPARATE IDENTITIES. THE GFS...HOWEVER...IS STILL MUCH STRONGER WITH
THE EAST COAST STORM AND A LITTLE FASTER AND FARTHER NORTH WITH THE
SYSTEM THROUGH THE GREAT LAKES. THE STRONGER THE EAST COAST
SYSTEM...THE MORE MOISTURE THAT WILL BE ROBBED FROM MAKING IT INTO
THE GREAT LAKES.
A COUPLE OF SURFACE TROUGHS ON SUNDAY AND SUNDAY EVENING WILL
PROVIDE EXTRA FORCING FOR AN EXTENDED PERIOD OF SHOWERS AND
THUNDERSTORMS. ONGOING CLOUDS/PRECIP AND WEAK COLD AIR ADVECTION
WILL HOLD TEMPS AT 80 OR BELOW...THUS SOMEWHAT LIMITING THE
INSTABILITY POTENTIAL...BUT FORECAST SOUNDINGS STILL SHOW BETWEEN
1000 - 1500 J/KG FROM FLINT AND SOUTH. FREEZING LEVELS WILL BE
LOWERING...BUT WITH CONTINUED WEAK/UNIMPRESSIVE WIND FIELDS AND NOT
TERRIBLY IMPRESSIVE DYNAMICS...THE SEVERE POTENTIAL LOOKS QUITE
LOW...AND LIMITED TO HAIL. RAIN WILL BE THE BIG STORY...AS PW`S
CONTINUE TO PERSIST NEAR 1.5 DURING THE DAY WITH THE NAM INDICATING
OVER 1.6 PW`S DURING THE AFTERNOON. WEAK STEERING CURRENTS WILL SET
THE STAGE FOR SLOW MOVING MULTICELLULAR CLUSTERS OF STORMS
POTENTIALLY PRODUCING VERY HEAVY DOWNPOURS. THE AMOUNT OF RAIN
RECEIVED WILL LARGELY DEPEND ON HOW MUCH MOISTURE THE EAST COAST
SYSTEM TAKES AWAY...BUT REGARDLESS...SUNDAY WILL BE A WET AND STORMY
DAY.
A DRY SLOT AND FIRST SHOT OF COOLER AIR BEGINS TO FILTER IN
BEGINNING LATE SUNDAY EVENING BEHIND SURFACE FRONT.
MOISTURE/DYNAMICS WILL INCREASE ONCE AGAIN AHEAD OF MAIN COLD FRONT
AND UPPER LEVEL TROUGH AXIS MONDAY AFTERNOON. STRANGELY ENOUGH...THE
NAM AND GFS MOVE BACK INTO EXCELLENT AGREEMENT ON MONDAY REGARDING
THE FRONTAL PASSAGE...WITH SCATTERED SHOWERS/THUNDERSTORMS POSSIBLE
AHEAD OF THIS FRONT. A REINFORCING AND MUCH COLDER AIRMASS WILL MOVE
IN OVERNIGHT AND KEEP US BELOW NORMAL FOR THE FIRST HALF OF THE WEEK
BEFORE MODERATING LATER IN THE WEEK.
MARINE...
THE STORY CONTINUES WITH LIGHT WINDS FOR ALL MARINE AREAS THROUGH
THE WEEKEND. A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS WILL EXIST
THIS EVENING WITH A CHANCE OF SHOWERS AND THUNDERSTORMS FOR THE
REMAINDER OF THE WEEKEND. A COLD FRONT WILL EVENTUALLY SWEEP
THROUGH THE REGION MONDAY AND MONDAY NIGHT BRINGING COOLER AIR.
WIND AND WAVES ARE EXPECTED TO INCREASE BEHIND THIS FRONT AS THE
WINDS INCREASE.
