... Warming trend tonight. Approaching cold front brings all rain on Wednesday, transitioning to all snow by early Thursday. Cold fronts bring colder air next weekend.
NEAR TERM /THROUGH WEDNESDAY/... As of 1005 PM Tuesday...
Adjusted the timing of the POPs later in the overnight period and slowed the advancement towards the Ohio River. Also utilized the latest HRRR data for the winds, which will continue to be tricky overnight with warm air advection off the surface having an affect on the temperatures. Non diurnal trend expected again tonight with many areas warming slightly. Mountain valleys could still decouple and radiate however.
As of 725 PM Tuesday...
Made a few adjustments to wind gust potential for the mountains Wednesday based on latest model trends. Forecast soundings for tonight suggest a stout inversion, helping to contain strong winds from reaching the surface across the Lowlands overnight.
As of 230 PM Tuesday...
Surface high pressure continues in control through early tonight. A cold front will shift the high pressure to the east, to arrive along the OH River overnight. Deep low level winds from south to southwest will provide warm air advection through Wednesday.
Have rain showers reaching the OH River during the predawn hours Wednesday, a considerable delay on onset from previous model runs. Expect rain to spread east transitioning into all snow after midnight Wednesday into Thursday morning.
The main area of concern is the eastern slopes where temperatures could remain below freezing through Wednesday morning. If the rain reaches these areas before they warm up, freezing rain could be possible.
Went with the CONShort for temperatures through the period.
SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... As of 245 PM Tuesday...
The forecast period starts off with a cold front associated with the low pressure system to the north sweeping across the area bringing rain at first. Precipitable water is expected to be over an inch throughout the area which is anomalously high for this time of year. For this reason and with the help of a surface low developing south ahead riding up along the cold front, which will slow down the progression slightly, the area will likely see at least an inch of rain widespread. Localized higher amounts near the southern and mountainous areas along the VA border are possible. Before a transition to all snow there may brief spots of sleet and freezing rain, however this will be so short live that it will not be impactful. Am expecting around an inch of total accumulation of snow with some higher amounts in the mountains. With most of the dendritic growth zones drying out Thursday morning accumulations slow down on the back side of this system and not expecting much more accumulations into Friday.
LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... As of 245 PM Tuesday...
As the light snow showers linger in the mountains and tapers off Friday evening a series of short waves will be sweeping through the area over the weekend into the middle of the week. This will bring intermittent bursts of snow flurries. Cold bursts of air with every wave will allow temperature profile to become colder and colder making snow ratios quite large so am expecting a lot of drier snow to fall, so accumulations are expected to be confined to mainly the higher elevations where an upslope flow will be takeover.
