.
SATELLITE ANALYSIS AND TRENDS...MOD TO HVY RAINS FROM TSTORM ACTIVITY
ACROSS ERN WY AND PARTS OF MT TODAY HAS CONTRIBUTED TO ANY RECENT SNOWMELT
TO SWELL RIVERS IN PARTS OF THE REGION. LOWER HALF OF UPPER TROF SEEN
IN WV IMAGERY HAS BEEN SLOWLY MOVING EWD ACROSS SRN UT WITH AN EMBEDDED
VORT WHILE THE NRN HALF OF THE UPPER TROF STAYED IN RELATIVELY THE
SAME LOCATION ACROSS E WA/E OR TDY. THIS HAS ALLOWED FOR MOISTURE AXIS
TO STAY POSITIONED ACROSS ERN WY AND E TO N CENTRAL MT FOR MOST OF THE
DAY. OBJECTIVE ANALYSIS INDICATES THETA-E AXIS EXTENDS NWD FROM THE TX/OK
PANHANDLES ACROSS THE FRONT RANGE OF CO IN E WY AND SE MT. CONVECTIVE
CLUSTER OVER E WY..ALONG WITH THE ONE OVER E CO/SW NE ARE BOTH WITHIN AN
AREA OF STRONG UPPER LVL DIFFLUENCE SHOWN BY GOES STLT WINDS THAT HAS
HELPED TO MAINTAIN BOTH. 00Z PW ANALYSIS INDICATED THAT 0.8" PW VALUES
EXTENDED NWWD FROM CENTRAL NE TO RAP AND ONWARD TO GGW.
.
THOUGH PREVIOUSLY MANY OF THE TSTORMS WERE MORE SEPARATE..RECENT
IR IMAGERY SHOWS A COOLING TREND WITH THE CELLS ALONG THE SLOWLY EWD
ADVANCING WARM FRNT IN SE WY. CLOUD TOP TEMP OF -67C IS PRESENT WITH THE
SLOW MOVING LINE OF CELLS OVER PLATTE/NIOBRARA COUNTIES AND APPEARS TO
BE TRYING TO EXTEND SWD BEYOND KBRX. AN OVERSHOOTING TOP IS SEEN ON MOST
RECENT VIS IMAGE JUST N OF THIS STN AS WELL WHICH IS ONLY ENHANCING THE
RAINRATES. ESTIMATE BETWEEN 1-1.4" HAS OCCURRED OVER PLATTE COUNTY FROM
01-02Z WITH ALMOST NO MOVEMENT OF LINE SEEN ON VIS IMAGERY. CONTINUED 850
MOISTURE FLOW WILL ALLOW FOR SLOW MOVING STORMS TO PRODUCE MOD/HVY RAINS
OVER ERN WY INTO SE MT FOR THE NEXT SEVERAL HRS. WILL CONTINUE TO MONITOR.
