... The chance of precipitation returns mainly south of Pittsburgh overnight and Monday. Dry conditions, a warming trend in temperatures, and abundant sunshine can then be expected through much of the week.
NEAR TERM /THROUGH MONDAY/... 7pm update...continued with the trend of decreasing rain coverage and shifting that coverage a bit further southward. Latest ops and hires models are in good agreement that most, if not all, of the rain will remain south of PIT.
Tonight's round of precipitation will come from a weakening upper level shortwave. At this point have generally kept likely pops south of Interstate 70, with decreasing chances to the north. A few flakes could be seen around I-80, but no accumulation is expected. With extensive cloud cover, lows will be 5-15 degrees warmer than last night.
A relative lull in precipitation should come around sunrise before the influence of surface low pressure moving across Kentucky and North Carolina is felt. This will cause another northward surge in precipitation, but the chance for precipitation shouldn't make it much past US 422, leaving the I-80 corridor completely dry. Categorical pops are still in the forecast from the Mason-Dixon line south. The effect of cloud cover tomorrow will be to knock down high temperatures, with values 5 to 10 degrees cooler than Sunday.
SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... Showers will persist in the ridges Monday night, with different models showing different timing as to how quickly precipitation will depart. The longer it takes precip to depart, the greater the chance for snow accumulation, however minor it may be. At this point just have a dusting in eastern Tucker County. Overnight lows will drop 10-15 degrees from the night before thanks to clearing skies and radiational cooling. Surface high pressure will then build across the region for the middle of the work week, allowing for sunny skies. Although highs on Tuesday will vary little from Monday, temperatures will surge into the upper 40s and 50s on Wednesday.
LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... The surface high pressure should hang on through at least Thursday, then models become a bit murky through the rest of the extended forecast. The European is faster than the GFS with passing a cold front through the region, but both model suggest a chance of showers is possible Friday, Saturday, and Sunday. Apparently the price to pay for 3 nice days in the middle of the week is the chance for showers the next 3 days at the end of the week. Temperatures will be above normal through Sunday, when the front may have crossed the region and brought in colder air.
