KEY MESSAGE 1: Trending humid with heavy downpours and localized flash flooding possible Wednesday into the weekend After a very nice/refreshing start to the week, deep moisture surge of high pwats within a return SW flow will spell an increased risk of heavy drenching downpours and localized flash flooding Wednesday into the upcoming weekend. WPC continues to show broad marginal risks of excessive rain (ERO) given the uncertainty in the location of heavy rainfall. Conditions will be warm and quite sticky/humid with dewpoints in the 65-75F range; muggy nights 5-10+ degrees above the historical average. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... VFR through most of tonight. Surge of low level moisture will likely bring MVFR ceilings into the southern half of the central PA airspace Wednesday morning. Best odds for +RA and brief IFR visibility appears to be in the KMDT/KLNS vicinity Wednesday PM. Outlook... Thu-Sun...Pockets of fog in the morning. Scattered showers/isolated t-storms with heavy downpours and localized restrictions. && .CTP WATCHES/WARNINGS/ADVISORIES...
