.SHORT TERM /TONIGHT THROUGH FRIDAY/...
STRONG COLD FRONT IS JUST ABOUT TO CLEAR OUR CWFA. SCATTERED SHOWERS
ALONG THE FRONTAL BAND HAVE BEEN PRETTY HIT AND MISS ALTHOUGH A FEW
TSTMS WERE GENERATED...INCLUDING NEAR DCA. DO NOT EXPECT ANY
ADDITIONAL PRECIPITATION TNGT EXCEPT FOR THE WESTERN UPSLOPE
FAVORABLE AREAS WERE A FEW INCHES OF SNOWFALL WILL BE LIKELY
OVERNIGHT. HAVE ISSUED A SNOW ADVISORY THERE WITH FAVORABLE
TRAJECTORIES AND PASSAGE OF H5 VORT ENERGY...ALTHOUGH MOISTURE FETCH
ISNT VERY GOOD. 1-3 FCST IS IN LINE WITH LATEST HPC THINKING.
MOSTLY CLEAR SKIES EAST OF THE MTS TNGT AND AGAIN ON FRIDAY AS HIGH

MAIN FEATURE OF INTEREST IN THE LONG TERM IS BIG PLAINS STORM
WHICH IS FCST TO MOVE EAST AND AFFECT THE MID ATLC REGION LATE SAT
NIGHT THROUGH SUN EVENING. USED A BLEND OF GFS ENSEMBLE MEANS AND
SREF MEANS FOR BASIS OF FCST TO SMOOTH OUT DIFFERENCES BETWEEN
INDIVIDUAL MODELS. GUIDANCE CONTINUES TO SUGGEST A WINTRY MIX
EVENT ALTHOUGH IT DOES NOT APPEAR ANYWHERE CLOSE TO THE VALENTINES
STORM OF LAST WEEK. QPF IS FCST TO BE SIGNIFICANTLY LESS THAN
WITH LAST STORM AND HIGH PRES TO THE NORTH IS ALSO MUCH WEAKER
WHICH WOULD ALLOW WARMER AIR TO PENETRATE FURTHER NORTH. SOME
MINOR ACCUMULATIONS OF FZRA AND SLEET LOOK POSSIBLE BEFORE A
CHANGEOVER TO RAIN OCCURS SUN AFTERNOON. AFTER THE STORM EXITS THE
