633 FXUS61 KRLX 230505 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 1205 AM EST Sun Feb 23 2025 .SYNOPSIS... Dry through Monday with moderating temperatures. There is a chance for light precipitation on Tuesday, and then a better chance for precipitation Wednesday night through Thursday night. && .NEAR TERM /THROUGH SUNDAY NIGHT/... As of 1205 AM Sunday... A surface high pressure system will provide dry weather today and tonight. Temperatures today will moderate a bit, but still remain below normal for this time of year. An upper level disturbance will move across tonight providing some clouds to central Ohio and northern West Virginia, but no precipitation is expected with this disturbance. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... As of 245 PM Saturday... Dry air associated with remnant arctic high pressure rules the roost this period, as the high sits over the southeast and middle Atlantic states, keeping Gulf and Atlantic moisture at bay. As a result, warm advection low-level flow beneath west to northwest mid/upper-level flow does not moisten up the atmosphere much, and a mid/upper-level short wave trough crossing Tuesday may barely be able to squeeze out a shower across northern portions of the area, with the small probability of a snow shower over the higher mountainous terrain. The system pulls out Tuesday evening without much of a cold frontal passage, allowing high pressure to build back in by dawn Wednesday. Low cloud to begin Tuesday night give way to some increase in high cloud toward dawn Wednesday. Lowered lows from central guidance in the normally colder spots Sunday night, even with patchy mid/high cloud. While cold, Sunday night will not be as cold as recent nights or even tonight, and the warming trend in general continues. Radiative cooling under high pressure Tuesday night, again amid some cloud, stunts the warming trend on lows temporarily. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 245 PM Saturday... High pressure right over the forecast area Wednesday morning sets up a dry Wednesday, with a chilly morning followed by a milder afternoon, as the warming trend starting this weekend resumes. A southern stream short wave trough crosses late Wednesday night through Thursday. It may be able to tap a bit more moisture than its early week predecessor. However, even as high pressure to the south and east weakens and exits, the southern stream system will still not be able to tap much Gulf or Atlantic moisture, as low level flow beneath it remains light. While precipitation may be more widepsread compared with Tuesday, amounts will be light. The chance for thunder with this system appears quite small, given a morning frontal passage and a dearth of moisture, as suggested by surface dew points only climbing into the mid 40s ahead of it. The system will be able to pull a cold front through the area Thursday morning, and snow showers are possible, at least in the mountains, Thursday night, before precipitation ends on Friday. High pressure of Pacific origin pays a brief visit Friday afternoon. A northern stream mid/upper-level short wave trough then drives a cold front at least into the area on Saturday, with the chance for showers, possibly snow showers across the higher mountainous terrain. After the warming trend to start the long term period, temperatures drop back to normal to end the work week amid air of Pacific origin behind the cold front, but then climb back above normal ahead of the next cold front on Saturday. && .AVIATION /06Z SUNDAY THROUGH THURSDAY/... As of 1205 AM Sunday... VFR conditions can be expected through the period. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z MONDAY... FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: None.
