... High pressure, but lower moisture slow to clear. Remaining cool through mid week, but modest warming and dry for the end of the week. Strong system next weekend.
NEAR TERM /THROUGH TONIGHT/... As of 625 AM Tuesday...
Very few changes this morning. DZ has shown up in some of the observations, and will keep this going forwards.
As of 220 AM Tuesday...
Currently in a post frontal environment with lower level saturation and lingering showers, most numerous in the mountains but extending back to the Ohio River. Temperatures to fall, but not overly quickly, as a colder airmass filters back into the the middle Ohio Valley and central Appalachians. Not a traditional diurnal temperature curve for Tuesday, but as temperatures trend lower through the period, a weak uptick during peak heating can be expected. That said, not necessarily all locations will have their max temperature during these midday hours. It is likely that the mountains will just continue to fall through the day and into the tonight period. This is not an overly cold airmass by any means, as the thermal trough setting up over the northeastern mountains will hit around -9C at 850mb.
The hardest part of this forecast is the potential for drizzle/freezing drizzle for mainly the mountains and whether or not to include it in the forecast. The depth of the lower level moisture will shrink as high pressure builds in from the west, and have the area without POPs tonight.
SHORT TERM /WEDNESDAY THROUGH FRIDAY/... As of 235 AM Tuesday...
Overall, mainly dry and cool weather in the short term period, with high pressure in control. A weak disturbance will move across the northeast late Wednesday. Precipitation type is difficult to pinpoint at this time, but model soundings and forecast builder suggest an overall lack of significant moisture depth, and thus elected to change previous snowfall forecast to patchy drizzle.
LONG TERM /FRIDAY NIGHT THROUGH MONDAY/... As of 235 AM Tuesday...
Weather becomes more active in the long term period. There is still quite a bit of uncertainty in the details of a low pressure system and upper shortwave trough that will move into the area in the Friday night through Saturday time frame. Concern exists with the possibility of cold air damming along the eastern slopes of the Appalachians as moisture from the approaching system moves into the region, creating the possibility for a wintry mix late Friday night through Saturday morning, before transitioning over to all rain by late Saturday morning. In addition, strong southerly flow will result in high moisture transport into the region, with heavy rain a good possibility with the system. Have elected to go ahead and introduce the possibility for the above mentioned hazards in the HWO, and kept wintry accumulations to a minimum at this point, due to the uncertainty in the situation.
