-- Changed Discussion --
AN UPPER LEVEL TROUGH AXIS WILL BE CROSSING THE AREA TODAY...TRAILING THE SURFACE COLD FRONT THAT MOVED THROUGH IN THE EVENING. FALLING TEMPS AT 500 MB UNDER THE TROUGH COULD RESULT IN SOME INSTABILITY AND CU DEVELOPMENT TODAY...MAINLY NORTH...BUT NO PRECIP IS EXPECTED. AT THE SURFACE...DRY AND COOLER AIR WILL CONTINUE TO FILTER IN FROM THE NORTH. HIGHS WILL RANGE FROM THE UPPER 70S SOUTH WHERE SUN WILL BE MORE ABUNDANT...TO LOWER 70S NORTH WHERE MORE CLOUDS ARE EXPECTED. TONIGHT WILL BE CLEAR AND NEARLY CALM WITH HIGH PRESSURE OVER THE OHIO VALLEY...ALLOWING LOW TEMPS TO FALL INTO THE 40S AND LOWER 50S. .LONG TERM (TUESDAY THROUGH SUNDAY NIGHT)... HIGH PRESSURE WILL REMAIN THROUGH THE END OF THE WORK WEEK. MOSTLY CLEAR SKIES AND DRY WEATHER WILL BE PRESENT EACH DAY...WITH TEMPERATURES SEVERAL DEGREES BELOW NORMAL THROUGH THIS TIME. ONLY FEATURE TO NOTE IS INCREASED CLOUD COVER AND RAIN CHANCES BY THE WEEKEND...MAINLY IN THE SOUTHERN FORECAST AREA...BEGINNING WITH WRAP AROUND MOISTURE FROM THE HIGH PRESSURE THAT MOVES OFF TO THE EAST COAST BY SUNDAY. WINDS WILL SHIFT TO THE SOUTH AND SOUTHWEST DUE TO A DISTURBANCE DEVELOPING OVER THE EASTERN PLAINS...WHICH WILL ALSO BRING INCREASED MOISTURE ADVECTION AND LIFT TO THE AREA. MODELS SEEM TO WANT TO SLOW DOWN THE HIGH PRESSURE AND WIND DIRECTION SHIFT...SO CONFIDENCE IS LOW ON TIMING OF THIS INCREASED MOISTURE ADVECTION.
