Forecast for Monday, August 13, 2012

A few clouds around early this evening will thin and dissipate with the loss of daytime heating and so will the shower affecting far southern portions of Delaware. Tonight, expect a very comfortable night with low temperatures in the upper fifties and lower sixties in the far north to around the upper sixties in the urban centers.

For Monday, while there may be a few fair weather clouds in place, the sky conditions are expected to be mostly sunny. There is a slight chance of an isolated shower in the far northwestern fringes of the area.

On Tuesday, a cold front will approach the region late in the day. A southwest flow ahead of the front should result in an increase in the moisture content of the air. Dew points are expected to rise into the upper sixties, making it feel humid again. In response to the cold front, some afternoon showers and thunderstorms are expected. Gusty winds and hail are possible with any thunderstorm. On Wednesday, this cold front pushes offshore. There is a bit of uncertainty regarding how fast it moves away, thus I retain some clouds mixed with sun on Wednesday with a shower or thunderstorm threat still present.

On some days this week, we will be flirting with 90 degrees. Most highs will top out in the upper eighties, but  a few isolated 90 degree readings cannot be ruled out if we see enough sunshine. 

Thursday looks like a mainly sunny day, before another more potent cold front approaches late Friday into Saturday. This front will also likely trigger showers and potentially some thunderstorms. Later forecasts may have to push the timing back if waves of energy can slow down the front and make for a wetter outcome. At this moment, next Sunday looks like the beginning of some substantial relief from the summertime warmth we have been having.We will have our eyes on the tropics to see if anything becomes a threat to the Western Atlantic or Gulf Coast as we approach the peak of the hurricane season in September.
