DISCUSSION

KEY MESSAGE 1...Rain/drought relief not to return until Sunday.

KEY MESSAGE 1 DESCRIPTION... WV imagery not looking very July-like with a deep cutoff/occluded low in the Northeastern U.S. Locally the resulting low level flow acquires a northerly component making for lower dewpoints over the next few days. Although there is a semblance of dry advection there is little to no thermal advection keeping temperatures pretty close to normal. The next trough will be diving into the OH and Upper MS Valleys Friday night into Saturday. Its weak surface reflection will push a warm front through on Sunday. Dewpoints rise considerably Sat night into Sunday with rain chances then precipitously rising Sunday into Monday.

AVIATION /18Z WEDNESDAY THROUGH MONDAY/

VFR. A light pressure gradient will keep winds light and variable while downsloping flow aloft around a trough in the NE keeps skies clear.

Extended Forecast... VFR conditions should dominate Wednesday through Saturday.

MARINE

Tonight through Sunday... The post-frontal gradient is progged to remain very weak for days now. With all of the longer period swell energy remaining well offshore this only leaves behind the diminutive wind waves. This will gradually change over the weekend as a warm front lifts north across the area and winds and seas both increase, though the shorter periods will continue to dominate.

ILM WATCHES/WARNINGS/ADVISORIES

NC...Coastal Flood Advisory from 8 PM this evening to 1 AM EDT Thursday for NCZ107. SC...None. MARINE...None.
