NEAR TERM /THROUGH TONIGHT/... As of 650 AM Sunday...
Made a minor tweak to temperatures as locations in the northern and central mountains are currently slightly cooler than original forecast as much of this area is in the mid/upper 40s. Thus, made an update based off latest observations and trends, but other than that, no additional changes were needed at this time.
As of 248 AM Sunday...
Latest satellite imagery and observations reveals that river valley fog has once again formed this morning across parts of the area, with the greatest coverage so far across the Tug Fork region and much of central WV. Some lingering stratus across the northern FA has delayed fog development so far, but should still be possible, especially near EKN.
Upper level ridge in eastern Canada remains in control today, supporting a very dry atmosphere with PWATs around a modest 0.50 inches throughout the region. Forecast soundings reveal that the subsidence today will lead to a stable layer around 5-7 kft AGL, yielding the development of a cumulus deck this afternoon as diurnal heating increases. Weak warm air advection will occur as the upper ridge axis north of the region continues to shift further eastward. Thus, temperatures will be a degree or two warmer today than yesterday, with the majority of the area around or just above 80F.
Cloud cover is expected to increase from west to east this evening as a shortwave trough is progged to track across the mid Mississippi Valley. Increasing southwest flow ahead of this feature will bring an increase of moisture into the area by the end of the period, but the majority of precipitation is expected to hold off until the short term period.
SHORT TERM /MONDAY THROUGH WEDNESDAY/... As of 240 AM Sunday...
Pattern becomes active again with in southwest flow aloft, low amplitude trough axes, and lower level moisture advection back into the region. Despite the change in the column to more favorable conditions for upward motion, the thunder chances are rather modest going into Monday night/Tuesday. The better dynamics will remain to the west, closer to the frontal boundary that will work its way through later in the short term. The speed of the cold front will be governed by a surface low north of the Canadian border, in a system that is occluded/stacking and eventually filling. This could play a little bit of havoc with the timing, but the front should be through the mountains Wednesday. A tropical system moving northeastward away from the coast could also hamper forward speed, but the main interactions should be well east of us.
LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... As of 240 AM Sunday...
A return to drier/cooler/quieter conditions returns for the end of the week, but the next trough axis aloft and frontal boundary will sink southward into the area for Saturday. Dewpoints in the mid 50s to lower 60s will dictate a slightly greater diurnal temperature trend as we get later into summer.
