The new JMA Weeklies paint a wet and active picture for Week 1, but begin to suggest we get into a milder, drier pattern as we push into the middle and latter portions of May…

Week 1:

The “mean” upper air pattern places coastal ridges with a cool trough settling into the central.  The end result will be a wet and active regime, locally, this weekend into next week.  Though we’ll see a “spike” in temperatures Sunday, the overall theme is a chilly one as we open the month of May.  In fact, temperatures will trend significantly cooler than average as we push into next week.

Week 2:

While it still looks chilly (compared to average), the JMA Weeklies suggest a “calmer” weather pattern moving in.  Wet anomalies are noted through the Rockies and Central, but a drier trend across the east, including the Ohio Valley.

Weeks 3-4:

Wet times remain across the Central and spread into more of the southern tier, as well.  Slightly cooler than normal temperatures are also forecast across the Southeast.  Budding warmth seems to develop over the West.
