On Wednesday night, I aired my expectations for the month of May. Heat should continue building through the nation's midsection and the Southwest U.S. through the month, while a Northeast U.S. trough sends surges of cold south from Canada and keeps temperatures near normal for much of the Eastern United States. A similar phenomenon is expected in the Pacific Northwest. Meanwhile, the intersection of this sagging jet stream with available moisture from the Gulf of Mexico should mean a few heavy rain events on the south side of the Westerlies, and I've indicated above normal precipitation for this area. In the Northeast, jet stream disturbances may deliver a couple of rain events, but total amounts are likely to be near normal for the month.
