.DISCUSSION...

ELONGATED HIGH PRESSURE RIDGE SLIDING DOWN THE LEE SIDE OF THE
ROCKIES INTO THE C U.S. THIS MORNING...WITH TIGHT PRESSURE
GRADIENTS TO REMAIN ACROSS AL TODAY BEHIND THE SURFACE FRONT...
WHICH IS DOWN TO S FL THIS AM. WITH THE TIGHT GRADIENTS...LOOK FOR
BRISK NW WINDS TO CONTINUE TODAY AND A WIND ADVISORY REMAINS IN
EFFECT FOR TODAY FROM 10AM-6PM. ALSO...SOME WRAP AROUND MOISTURE
BEHIND THE TIGHT RETREATING LOW OVER THE MID ATLANTIC COAST WILL
HINDER DAYTIME HEATING TODAY. SO BETWEEN THE TWO...CONDITIONS
TODAY WILL FEEL QUITE NIPPY. AS THE RIDGE CONTINUES TO SLIDE SEWD
INTO TONIGHT GRADIENTS SHOULD BEGIN TO RELAX SOME BUT WINDS ARE
NOT EXPECTED TO DECOUPLE GREATLY TONIGHT. HOWEVER...WITH
CONTINUED COLD AIR ADVECTION WE ARE EXPECTING TEMPERATURES TO BE
COOLER TONIGHT GOING BELOW FREEZING AND SINCE THIS IS A LATE
SEASON FREEZE WILL GO WITH A FREEZE WARNING FROM 5Z TONIGHT TILL
14Z TUE MORNING. WITH LESS WIND AND CLOUD COVER EXPECTED FOR TUE
NIGHT...FREEZING TEMPERATURES ARE POSSIBLE ONCE AGAIN TOMORROW
NIGHT AS WELL SO A WARNING IS LIKELY AGAIN FOR TUESDAY NIGHT.
THROUGH TUESDAY WITH WRAP AROUND MOISTURE PRESENT AND WEAK NW FLOW
DISTURBANCES POSSIBLE...A FEW FLURRIES ARE NOT COMPLETELY OUT OF
THE QUESTION ACROSS THE FAR NRN COUNTIES...BUT MOISTURE WILL BE
SHALLOW AND CHANCES ARE VERY LOW AT THIS TIME SO WILL LEAVE
UNMENTIONED IN FORECAST FOR NOW.

SO THRU TUE NT...LOOK FOR RATHER CHILLY DRY CONDITIONS...WITH THE
RIDGE INCHING CLOSER. AS WE MOVE TOWARD THE WEEKEND THE SURFACE
RIDGE IS EXPECTED TO GRADUALLY SHIFT EWD FROM THE C U.S. TO JUST
OFF THE ATLANTIC COAST BY EASTER SUNDAY. THUS...OUR LOW LEVEL FLOW
WILL SHIFT FROM BRISK NW TODAY AND TUE TO LIGHT NRLY WINDS WED-
FRI...THEN TURNING BACK TO E SAT AND SE SUN. NW FLOW DISTURBANCES
COULD BRING SHOWER ACTIVITY BACK AS SOON AS FRI AFTERNOON BUT
WOULD BE LOW CHANCES THRU SAT WITH LIMITED MOISTURE. BY SUN...
MOISTURE COULD BE SUFFICIENT ENOUGH ALONG WITH THE UPPER FLOW
TRANSITIONING TO A WEAK LONGWAVE TROUGH ACROSS THE ERN U.S. SO
ALTHOUGH TIMING IS NOT IN TOTAL AGREEMENT...COULD END UP BEING A
WET EASTER WITH A FEW SHOWERS/TSTORMS AT TIMES. ALTHOUGH
TEMPERATURES MODERATE SOME AND MOISTURE BEGINS TO INCREASE...
OVERALL INSTABILITY IS STILL LOW SO ONLY LOW POPS FOR NOW FOR THE
EXTENDED WITH NO SIGNIFICANT FRONTAL SYSTEM CLOSE BY TO FOCUS IN
ON.
