My last post two weeks ago ended with the following… If this all happens as currently forecast, the 2nd half of June could end up cooler than normal due to a NW flow, but we may not see very much … Continue reading →

The 2nd in a series of weakening cold fronts will bring about a pattern change that will end the early-season heat wave and bring about a return to cooler weather. The first front will cross the Mid-South Tuesday and will … Continue reading →

One small change in the value of a teleconnection is all that was needed to change our weather from cool and wet to hot and dry. This is a perfect example of why seasonal forecasting is so difficult.

The prolonged negative PNA pattern that has controlled the weather across the Mid-South since mid-March (right about the time I stopped posting) has kept things quiet and dry. That will change as a bowling-ball 500 mb low will barrel across … Continue reading →

The GFS and ECMWF have very different interpretations of Easter weekend weather. While the GFS shows a couple of minor shortwaves rotating around the trough, the ECMWF has a blizzard for New England. How can two models that use the … Continue reading →
