We are looking at a repeat of Monday for today with mostly sunny and cool conditions.

TUESDAY: A few high clouds and continued seasonably cool. Highs: 66 to 70 inland, 62 to 66 coastal. North wind 5 to 10 mph.

TUESDAY NIGHT: Increasing clouds and continued cool.  Lows: 44 to 48 inland, 48 to 52 coastal. Northeast wind 5 to 10 mph.

WEDNESDAY: Thickening clouds AM with rain arriving PM. Highs: 64 to 68 coastal. Northeast wind 5 to 10 mph.

DISCUSSION: A cool Canadian high pressure is moving out of the Ohio Valley this morning and will pass off the coast Tuesday. While that high pressure is in control of our weather today we can expect the continuation of sunny but cool weather. High temperatures only in the upper 60s will be close to 10 degrees below normal for the end of April.

By mid-week we will be watching a coastal storm develop off the Carolinas. The exact track and strength of this storm will depend on the interaction of a cold upper level features at the jet stream level. The first of these features is an upper level low that is across New England, centered near Nova Scotia. This will actually do an unusual thing and push WESTWARD, not eastward and out to sea. Because of this it will send a couple pieces of energy rotating counter clockwise around it, which in turn will capture another upper level low pressure that will move out of Texas on Tuesday.

The exact details on the track, strength, and impacts on us from this coastal storm will depend on how all these upper level systems interact with each other. But I’d plan on wet and windy conditions for Wednesday and Thursday and some minor flooding/high tides at the coast during that time.

But this should be our last shot of cold weather as by the weekend when the storm moves off the coast it will create a change in the jet stream pattern that finally bring the sunny and warm weather we have been wanting just in time for the start of May!
