In my last post I discussed how a ridge would build across the central U.S. Thursday and Friday in response to a deepening trough over the western United States. As often happens this time of year, the downstream polar vortex … Continue reading →

In my last post I mentioned that there was some model disagreement regarding the 2nd half of next week. I mentioned that the GFS called for a return to cold and wet while the European model kept the cold air … Continue reading →

The phased jet streak pattern mentioned in my previous post that resulted in rain every 2-3 days will transition to a less wet but cool northwest flow over the next week.

The rest of May is shaping up to be unsettled across the central United States as a perfect setup for shortwave generation in is place.

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 →
