Area Forecast Discussion National Weather Service Blacksburg VA 336 AM EDT Wed Jun 19 2024

High pressure will cover the region through the end of the week. This will result in unseasonably warm temperatures and mainly dry conditions. Any rainfall is expected to be isolated.

As of 330 AM EDT Wednesday...

Key Messages:

1) Warm and dry. Temperatures about 5 degrees above normal.

500mb (597dm) anticyclone is centered over the northern Mid- Atlantic...this persistent ridge of High pressure poised to remain nearly stationary through the near term...amplifying with time. Clockwise flow around the center (vcnty IAD) of the High will continue to focus main heat risk from Ohio Valley and Great Lakes into New England where westerly low level winds will advect plume of well above normal warmth across areas to our north. Our forecast area is positioned just south of the anticyclone with wind flow primarily coming from the southeast and off the Atlantic Ocean. This will mute our temperatures to some degree maintaining only minor heat related risks compared to our neighbors to the north. Temperatures over the next 24 hours across our forecast area will average about 5 degrees above the seasonal norm, but nothing extreme (yet). Longer range guidance suggests we will get a taste of this airmass by the weekend as the center of the upper ridge retrogrades and allows for a shift to westerly flow aloft and the formation of a lee trof over the southern Mid-Atlantic. Until then, our weather should feel seasonally warm for the time of year...skewed slightly to the above normal range with respect to the temperature...highs ranging from the upper 70s to mid 80s in the mountains and upper 80s to around 90 in the foothills and piedmont. Dewpoints today and tonight should remain at or below 65 and may even mix into the upper 50s. This little bit of drying should be enough to keep the heat index in check...the temperature generally mimicking the heat index. The dry air is also not good for CAPE, so not expecting any deep convection for our CWA today or tonight.

As of 110 PM EDT Tuesday...

Key Message:

1) Confidence is high for hot and dry conditions.

A 598 dam upper level ridge centered over Delaware and New Jersey will control the weather pattern across the Mid Atlantic during Wednesday night into Thursday. The ridge should slide towards the southwest across the Appalachian Mountains by Friday. Surface high pressure will remain situated off the East Coast during this time.
As a result, temperatures will continue to trend hotter with highs in the 90s becoming more common in the lower elevations as this work week concludes. The ridge should keep the atmosphere suppressed with a decent capping inversion preventing any development of showers on Thursday, and any convective activity on Friday should stay to the north across central West Virginia.

As of 110 PM EDT Tuesday...

Key Messages:

1) Confidence is moderate for increasing chances of showers and thunderstorms during the weekend and Monday.

2) Drier air may arrive by Tuesday.

The heat persists into the weekend, but the upper level ridge will keep heading southwestward towards the lower Mississippi River Valley as an upper level trough passes over the northern Plains.
This trough should cross the Great Lakes by Sunday night into early Monday. A cold front associated with this trough will reach the Appalachian Mountains during this timeframe. Consequently, the chance of showers and thunderstorms will increase on Saturday and peak during Sunday and Monday. It remains questionable on how far southward the cold front could advance by late Monday into Tuesday as it could stall somewhere across the Southeast, but some drier air may arrive from the north on Tuesday to lower the odds of convection.

As of 330 AM EDT Wednesday...

Some patchy areas of fog across the mountain valleys, particularly at LWB, this morning, otherwise expecting widespread VFR through the 24 hour TAF.


Thursday Through Sunday...High pressure will cover the region.
Aside from some morning river fog in the mountain valleys, conditions are expected to be primarily VFR. Little or no chance for rain is expected through Friday...then increase for the weekend. Heat and humidity will also increase for the weekend.
