... Crossing low pressure brings light precipitation tonight into Thursday morning. Dry weather Thursday afternoon and night will be followed by increasing rain chances Friday as another low approaches from the south.
NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... Eve update changes included tweaks to hourly trends based on the latest high res guidance and obs. trends, which indicate that clouds and warm advection in advance of low pressure moving across the Great Lakes should prevent surface temperature from falling under the freezing mark sufficiently long to preclude a freezing drizzle/ice-on-road-threat. The HWO mention has thus been removed.
Still expect a fast-moving surface/upper low combo to track just north of our region overnight. This remains an overall light precipitation event with the best lift remaining to our north with the upper low. Not much change was made to the overall PoP/weather structure, with likely PoPs generally north of US-422, which is where most of the snow will fall as well. Given the light precip and unimpressive snow ratios, generally an inch or less of accumulation is expected.
SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... The low exits off to the east Thursday morning, with some lingering light snow or light rain possible. Thursday afternoon and night will be dry with a mid-level ridge crossing the area. Temperatures will be near or just a couple degrees above climatology.
The next low pressure center tracks from the Gulf coast Friday afternoon and into the Tennessee Valley Friday night. Rain chances ramp up through the day Friday as isentropic lift builds through the day. PoPs/QPF for both Friday and Friday night are highest in the southeast where this contribution to lift is the highest, with values tapering to high chance in the northwest CWA. Other than a possible brief period of freezing rain at precip onset Friday morning, this is an all- liquid event. Above-normal temperatures will be the rule.
LONG TERM /SATURDAY THROUGH WEDNESDAY/... The low will continue to track into the middle Ohio Valley on Saturday, with continued rain chances. From here on, the ensembles show increased uncertainty with the low track, but most take the low off the Mid-Atlantic coast by late Sunday. The Sunday-Sunday night period is a relatively dry one for us. A shortwave and cold front will arrive and bring scattered rain and snow showers Monday. Building high pressure will bring dry weather Tuesday and Wednesday, with temperatures moderating towards normal.
