.SHORT TERM...

TONIGHT THROUGH SATURDAY MORNING...

~1000MB SFC LOW IS MOVING THROUGH THE GREAT LAKES...DRAGGING A COLD
FRONT TOWARDS THE AREA. THIS AFTERNOON THIS FRONT IS CURRENTLY
SITUATED ALONG A LINE FROM SHREVEPORT LA TO NE AR. EXPECT THIS FRONT
TO CONTINUE TO PUSH TO THE E TODAY. DUE TO STRONG PRESSURE GRADIENT
OF THE APPROACHING FRONT AND RETREATING SFC HIGH ON THE E
COAST...WINDS HAVE BEEN GUSTY TODAY...MAINLY BETWEEN 30-40MPH. EXPECT
THIS TO LESSEN AS WE GO INTO THE EVENING. OVERALL THINKING IS MOSTLY
UNCHANGED FROM THIS MORNING. KEPT THE SAME AREA IN THE GRAPHICS FOR
LIMITED THREAT FOR SEVERE STORMS...MAINLY GUSTY WINDS. GOOD DRY LOW
LEVELS...AS INDICATED WITH DEWPOINTS RISING SOME 20 DEGREES OR SO
WITH THE WARM FRONT LIFTING THROUGH...IS LEADING TO EFFICIENT MIXING
WITH GUSTY WINDS AND TEMPS WARMING NICELY INTO THE 70S ACROSS THE
REGION. THIS IS ALSO LEADING TO INVERTED V TYPE ENVIRONMENT THAT
INDICATES SOME POTENTIAL FOR SOME GUSTY WINDS IN ANY STRONGER STORM
THAT DEVELOPS. ALTHOUGH THE BEST HEIGHT FALLS ARE TO OUR N...WE HAVE
ENOUGH IN OUR NRN AREAS AND JUST ENOUGH MOISTURE AND LOW LEVEL LAPSE
RATES AND AROUND 30KTS OR SO OF EFFECTIVE SHEAR...SOME STORMS CAN NOT
BE RULED OUT...ESPECIALLY IN OUR N/NE...WITH SOME SPC MESOANALYSIS
SHOWING SOME LIMITED INSTABILITY ACROSS THE AREA MAINLY UNDER 500
J/KG. MAINTAINED OUR SEVERE AND WIND HAZARDS IN THE HWO/GRAPHICS FOR
TODAY.

REST OF THE PERIOD REMAINS QUIET AS THE FRONT MOVES THROUGH TONIGHT
AND RAIN/STORM CHANCES LESSEN AFTER 03Z THURSDAY WITH NEAR NORMAL
LOWS TONIGHT IN THE UPPER 40S TO LOW 50S. OVERALL REST OF THE
WEEKEND LOOKS NICE AS MUCH DRIER CONDITIONS ARE IN STORE FOR THE
WEEKEND. HIGHS WILL BE WARM AGAIN TOMORROW IN THE MID/UPPER 70S WITH
GOOD MIXING. A DEEP TROUGH AMPLIFYING OVER THE ERN CONUS...DRIVING
DOWN ANOTHER DRY FRONT EARLY FRIDAY MORNING AND LOWER PW'S CLOSER TO
A QUARTER OF AN INCH ON FRIDAY AFTERNOON IN THE WAKE. ONLY EXPECT
SOME PASSING CLOUDS WITH THIS FRONT. HIGHS FRIDAY WILL BE COOLER BUT
ONLY SLIGHTLY BELOW NORMAL IN THE UPPER 60S TO LOW 70S WITH LOWS
FALLING INTO THE MID TO UPPER 40S BY SATURDAY MORNING. OVERALL A VERY
NICE WEEKEND IS IN STORE IN THE WAKE OF THIS FRONT. /DC/

.LONG TERM...

SATURDAY THROUGH EARLY NEXT WEEK...

ANOTHER WEAK COLD FRONT WILL DROP SOUTH ACROSS THE AREA SATURDAY
NIGHT INTO SUNDAY MORNING. THIS WILL BE A DRY COLD FRONT AS LITTLE
MOISTURE WILL BE AVAILABLE WITH PWATS BELOW AN INCH. TEMPERATURES
WILL FALL INTO THE LOW/MID 40S BY SATURDAY MORNING. COOL HIGH
PRESSURE WILL SETTLE IN OVER THE AREA ON SATURDAY WITH HIGHS IN THE
60S FOR MOST OF THE AREA. UPPER RIDGING WILL BUILD OVER THE AREA
SATURDAY NIGHT INTO SUNDAY WITH THE SURFACE HIGH MOVING FROM THE
OHIO VALLEY INTO THE SOUTHEAST. LOWS WILL RANGE FROM THE UPPER 30S
IN THE NORTHEAST TO NEAR 50 IN THE SOUTHWEST.

THE SURFACE FLOW WILL BECOME SOUTHEASTERLY ON SUNDAY WITH WARMER
HIGHS IN THE MID 70S. THE GFS/ECMWF ARE BECOMING A LITTLE MORE IN
AGREEMENT OF AN UPPER TROUGH AND ASSOCIATED COLD FRONT MOVING ACROSS
THE AREA MONDAY EVENING INTO TUESDAY. THERE CONTINUES TO BE SOME
TIMING DIFFERENCES...BUT SHOWERS AND THUNDERSTORMS ARE BECOMING MORE
LIKELY DURING THIS PERIOD ALONG WITH INCREASING CHANCES FOR STRONG
TO SEVERE STORMS. THE SHOWERS AND THUNDERSTORM CHANCES WILL CONTINUE
THROUGH TUESDAY. THERE ARE SOME DIFFERENCES AS THE GFS HAS QUICK BREAK
IN RAIN AFTER TUESDAY BEFORE MORE MOVES IN LATER WEDNESDAY WHILE THE
00Z ECMWF HAS A MORE DISTINCT FRONTAL PASSAGE AND LONGER BREAK AND
STRONGER UPPER S/WV MOVING THROUGH WEDNESDAY THROUGH THURSDAY. 12Z
EURO LOOKS LESS IMPRESSIVE THAN THE 00Z AS IT IS LESS AMPLIFIED AND
WEAKER. REGARDLESS...MAINTAINED POPS THROUGH THURSDAY. /15/DC/

&&

.AVIATION...A COLD FRONT IS MOVING ACROSS THE AREA THIS AFTERNOON
BRINGING SCT SHRA/TSRA MAINLY WEST OF I-55. THIS FRONT WILL CONTINUE
