... The remnants of Barry affect the area through tonight. Deeper moisture moves out Thursday. Dangerous afternoon heat expected Friday and Saturday. A break in the heat comes early next week.
NEAR TERM /THROUGH THURSDAY/... As of 533 PM Wednesday...
Have made significant changes to precip chances for this evening/overnight. Main changes were to increase POPs for early this evening for southern and eastern CWA and to lower them from categorical to likely for the northern CWA. An additional update will likely be sent later this evening.
As of 250 PM Wednesday...
Scattered bands of showers with isolated thunderstorms will continue to develop or move across the area through tonight. This activity is associated with the remnants of Barry. Abundant moisture as seen in PWATs reaching 2.25 inches and surface dewpoints in the lower 70s. However, little dynamic forcing can be expected with this event. Heavy downpours could produce isolated minor water problems through tonight.
Pcpn intensity is expected to diminish toward midnight. Lower atmosphere could decouple tonight depending on clearing skies. This could produce areas of dense fog during the predawn hours Thursday over areas that receive rain. Otherwise, cloud cover could prevent fog formation.
SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... As of 225 PM Wednesday...
Big story continues be the heat and humidity slated for late week and the weekend, courtesy of upper level ridge axis shifting into the region. Guidance continues to fluctuate a a couple of degrees for highs both Friday and Saturday but remain steadfast on dewpoints. Given that MOS guidance has generally been too cool the past few weeks for highs, elected to accept the higher values from blend of models. As such, the combination of heat and humidity Friday and Saturday warranted issuance of excessive heat watch for most of the lower elevations earlier this morning. This area matches well with WPC probability grids for reaching 105. Though, confidence of reaching 105 is a bit lower across the northern Lowlands in the vicinity of the I-79 corridor. Regardless, I anticipate advisory level readings to be reached both days in those areas.
Chances for convection each day remain very small and confined to the mountains where elevated heat sources may contribute to isolated late day activity.
LONG TERM /SUNDAY THROUGH WEDNESDAY/... As of 235 PM Wednesday...
Heat wave breaks down this period, as a cold front approaches on Sunday, and then crosses on Monday.
Ridge reorganizes off the East Coast Sunday as upper level trof moves into the upper OH Valley. Models are hinting out moisture return resulting from these features which will increase shower/storm chances Sunday, perhaps as early as the morning. Depending on how much coverage there is Sunday afternoon, we may be looking at head advisory criteria, though warning levels are not anticipated.
It will take until late Monday to get the front through as the trof axis crosses. This means a good chance of showers/storms continue into Monday, though diurnally maximized.
High pressure builds into the region Tuesday and Wednesday for lower humidity and temperatures.
