... High pressure will bring generally fair weather and warm temperatures to the Appalachians and central mid Atlantic region through the weekend. A weak cold front may bring some showers to locations west of the Blue Ridge on Monday, but high pressure will once again build over the area with a return to fair weather through the middle of next week.
NEAR TERM /THROUGH SUNDAY/... As of 220 PM EDT Saturday...
Satellite imagery shows a good amount of cloud cover but radar indicates showers remain quite sparse, and expect this to remain the case through this afternoon with any lingering showers dissipating this evening and some valley fog developing overnight. High pressure surface and aloft then brings another day of fair weather with warmer temperatures to close out the weekend on Sunday.
Lows tonight will be a few ticks warmer than last night with readings around 60 east of the Blue Ridge and middle 50s west, though some 40s will be found in the deeper valleys in the west. Highs on Sunday will be in the upper 80s to near 90 east, low/mid 80s west.
SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... As of 245 PM EDT Saturday...
The upper air pattern deamplifies briefly early in the week allowing for a surface cold front to make passage Monday. The front is expected to be moisture starved with High Pressure over the Gulf Coast States blocking any substantial connection to the Gulf. As such, the cold front will pass through the forecast area within a westerly flow regime, causing most, if not all, of the shower activity to dry up as the front crosses the mountains Monday afternoon. Bottom line, little or no QPF is expected with this frontal passage, most of which will be confined to areas west of the Blue Ridge, and even then generally netting less than a tenth of an inch.
Temperatures Monday should easily climb above normal east of the Blue Ridge where the front is not expected to arrive until the late afternoon or evening. Mountain locations should be closer to normal, with clouds increasing Monday morning and helping to offset the temperature rise.
Post frontal conditions Tuesday will place the forecast area under dry air advection with surface High Pressure becoming re- established...temperatures closer to the seasonal norm.
LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 300 PM EDT Saturday...
Flat mean flow is forecast for mid-week with another dry surface frontal passage anticipated Thursday. After Thursday, a rapid transition to high amplitude flow is forecast with a full latitude long wave trof on the West Coast and an eastern U.S. Ridge of High Pressure. Some of the models indicate the eastern Ridge may gain an amplitude to something like we would see in August with a 594-596 dm 500H anticyclone centered somewhere vcnty of the mid-MS valley. As such this should effectively block moisture over a big piece of real estate to include our forecast area through next weekend, and potentially yielding a dry finish to the last full week of September...the 6 to 10 day outlook advertising temperatures well above normal and precipitation below normal. With 850MB temperatures returning to the +16 to +20 degree range, the possibility for a few more 90 degree days are still within reach in spite of the shortening diurnal cycle and fall equinox.
