FORECAST DISCUSSION: A very humid air mass has returned to Delmarva this evening along with much warmer temperatures. We might see an isolated shower this evening, but the rain chances will drop to near zero by 8 PM with mostly clear skies. Look for lows to dip into the low/mid 70's by sunrise. There may be some patchy fog in spots now that the nights are getting longer. Look for highs to climb above 93 degrees Friday with a heat index over 100 likely in the afternoon hours. Rain chances will climb later Friday night with widely scattered storms about into the evening, as a weak surface front approaches the area. The rain chance Friday night is over 50%.
A more unsettled weather pattern will arrive by the coming weekend with scattered to numerous thunderstorms Saturday, and perhaps at times on Sunday as well. Highs will reach the upper 80's as a more southerly wind flow returns Saturday. A stronger onshore flow will develop Sunday and bring highs back to near 80 on the coast with mid 80's inland. The water temps. across the region remain above normal and the nights will be a little above normal for the next 7-8 days at least. We will lose 16 minutes of daylight in the next 7 days.
