.DISCUSSION...

CLEAR SKIES AND STRONG RADIATIONAL COOLING HAS CAUSED TEMPERATURES
TO FALL INTO THE LOWER 40S IN MANY LOCATIONS THIS MORNING. BY THE
AFTERNOON...WIDESPREAD MID TO UPPER 70S ARE EXPECTED WITH A FEW
SPOTS POSSIBLY REACHING 80F AS A STRONG 500MB RIDGE MOVES EASTWARD
FROM TEXAS. TEMPERATURES WILL CONTINUE A WARMING TREND INTO SUNDAY
AND MONDAY WITH LOWER TO MID 80S AREA-WIDE AS THE RIDGE AXIS SHIFTS
EASTWARD ACROSS THE REGION.

THE RIDGE SHOULD SHIFT FAR ENOUGH EAST BY TUESDAY TO CAUSE AN
INCREASE IN LOW-LEVEL MOISTURE WITH SOUTHWESTERLY FLOW. A TROUGH
OVER THE GREAT LAKES REGION WILL HAVE AN ASSOCIATED TRAILING COLD
FRONT THAT WILL MAKE SLOW PROGRESS SOUTHWARD. THE HIGHEST MOISTURE
CONTENT IS EXPECTED TO BE LIMITED TO A NARROW ZONE NEAR THE FRONT
WITH PRECIPITATION REMAINING TO THE NORTH OF THE CWA FOR TUESDAY
AS UPPER-LEVEL SUPPORT EXITS INTO THE NEW ENGLAND STATES. BY
WEDNESDAY THE FRONT MAY CONTINUE TO MOVE SLOWLY SOUTHWARD AND
SHOULD BE LOCATED SOMEWHERE IN THE CWA WITH 30-40 POPS. WILL KEEP
20 POPS IN FOR WEDNESDAY NIGHT AND THURSDAY AS A THE FRONT PAUSES
AHEAD OF AN UPSTREAM SHORTWAVE. MODELS ARE IN BETTER AGREEMENT FOR
THURSDAY NIGHT INTO FRIDAY...INDICATING THE FRONT WILL BE SHUNTED
SOUTHWARD AS THE SHORTWAVE TROUGH AXIS SWINGS THROUGH. PERHAPS THE
COLDEST AIR OF THE SEASON COULD BE ON THE WAY BEHIND THIS SYSTEM.
