DISCUSSION
A FRONTAL SYSTEM SLOWLY APPROACHING FROM THE GREAT LAKES AND
NORTHEAST WILL DROP INTO THE AREA TONIGHT. NEAR RECORD WARM
TEMPERATURES ARE EXPECTED AHEAD OF THE FRONT. EVEN THOUGH DEW
POINTS WILL ALSO BE RISING, THE LARGE SPREAD WITH THE TEMPERATURES
WILL RESULT IN AFTERNOON RH IN THE 30S AND 40S. WINDS WILL BE WEST
TO SOUTHWEST BUT NOT QUITE AS GUSTY AS RECENT DAYS, WITH A SHIFT
TO SOUTH POSSIBLE FOR A TIME THIS EVENING EAST OF THE BLUE RIDGE
MOUNTAINS AND SOUTH OF US-50. SHIFTS TO THE NORTH, EAST, THEN
SOUTHEAST ARE ANTICIPATED TONIGHT AS THE FRONT DROPS SOUTH.
THE FRONT WILL STALL NEARBY OR OVERHEAD THROUGH THURSDAY,
INCREASING THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS. THERE WILL
ALSO BE A LARGE CONTRAST IN TEMPERATURES FROM NORTHEAST TO
SOUTHWEST ACROSS THE AREA ON THURSDAY. WINDS SHOULD BE LIGHT BUT
WITH VARIABLE DIRECTIONS GIVEN THE FRONT NEARBY. RH WILL ALSO BE
NOTABLY HIGHER GIVEN ONSHORE FLOW.
THE FRONT WILL LIFT NORTHWARD AS A WARM FRONT FRIDAY AHEAD OF A
STRONG COLD FRONT APPROACHING FROM THE WEST. THE NEXT OPPORTUNITY
FOR MORE NUMEROUS SHOWERS AND PERHAPS SOME THUNDERSTORMS WILL
OCCUR WITH THIS FRONT ON SUNDAY.
MORE FORECAST DETAILS AND PARAMETERS WILL BE AVAILABLE WITHIN 2 TO
3 DAYS OF THE REQUESTED DATE.
