NEAR TERM /THROUGH TONIGHT/... As of 215 AM Tuesday...
High pressure sails by to the north of the area today and tonight, providing dry and cooler weather. Stratocu in and near the northern and central WV mountains beneath a subsidence inversion early this morning, will mix out by late morning,
A southerly flow of warmer and more humid air starts to develop tonight, as the high moves off to the east, beneath upper level ridging. That ridge stiff-arms the upper level trough associated with the severe weather outbreak over the central U.S. early this morning. Nonetheless, patchy high and mid cloud out ahead of it will spill across today and tonight.
Central guidance looked reasonable on highs today beneath the low level inversion. Central guidance appeared reasonable for lows on hill and ridge tops tonight, while the lower MET and MAV guidance was blended in for the valleys.
SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... As of 335 AM Tuesday...
After a brief break from the heat and humidity earlier in the week, a strong upper level ridge in the southeast CONUS will allow the hot and humid conditions to make a comeback by mid to late week. As this feature builds into our region, heights aloft will rise and temperatures will will reach the mid/upper 80s across the area. While most of Wednesday will be dry across the region given the influence of the ridge and lack of any forcing, there will be at least a small chance of some isolated scattered showers and storms by Wednesday evening. This activity will be due to a remnant band of convection ahead of an occluded low pressure system in the upper Midwest. This activity should be on a weakening trend as it moves into our area, but models do suggest that enough elevated instability could be present to support a mention of thunder through Thursday morning. Have greatest POPs in southeast OH and northern WV with this weakening area of convection moving through.
Greater coverage of showers and storms will be possible Thursday as the upper ridge in the southeast slides slowly southward and several disturbances ride along the northern periphery of the ridge in the Ohio Valley. Each of the these disturbances will be capable of triggering rounds of ascent and coupled with good instability across the region (MLCAPE around 2,000-3,000 J/Kg), scattered showers and storms are more than possible. In addition, latest NAM soundings suggest favorable shear will also be present, with 0-6 km shear values around 45-50 kts. Thus, some of the storms could be strong based off some this recent data and trends will be watched closely over the coming days.
LONG TERM /FRIDAY THROUGH MONDAY/... As of 335 AM Tuesday...
As the ridge axis builds back northward on Friday and with a lack of any upper significant trigger for convection, thinking it will be mainly precipitation free across the region. There is just a small chance of an isolated diurnally-driven shower or storm, but most areas should be dry. It will also be another warm and humid day with temperatures in the mid/upper 80s across the region.
On Saturday, a shortwave trough will move across Ontario which will push a cold front into the Ohio Valley. This front will then stall across the region and combine with disturbances in the westerly flow aloft to support a better opportunity of showers and thunderstorms compared to Friday. Favored areas for convective activity at this point on Saturday appear to be in southeast OH closer to the frontal boundary, and near the mountains with the orographic influence. More convection will then follow for Sunday as additional shortwave energy rotates around the northern periphery of the ridge south of the region and it appears that coverage of storms for Sunday will be greater than Saturday with most of the region.
The ridge will still be in control by early next week and thus, a continuation of the heat and humidity is expected. Chances for showers and storms will also linger into the new week as well as the region remains on the northern periphery of the ridge.
