DAYS 1-5 (MAY 12-16)
Moisture overcomes dry air for some wetter weather, still focused in areas to the south, at times today as one wave of low pressure passes south of the region. A second low will come up from the southwest Monday and Tuesday and pass very slowly, bringing unseasonably cold air and more wet weather, some of which may fall in the frozen form in some locations. Yes, it can happen in May. Slow midweek improvement but not total improvement as upper level low pressure hangs around.

DAYS 6-10 (MAY 17-21)
Upper level low pressure may hang around for a couple days before being replaced by a flat ridge of high pressure. This period should be mostly dry, but not completely rain-free, though timing is uncertain on disturbances and shower threats, so will have to fine-tune that. The temperature trend should be warming, as it starts out below normal and ends near to above normal.
DAYS 11-15 (MAY 22-26)
Dry and mild start and end should flank a period of cooler/wet weather as low pressure passes during the middle of the period.
