Mainly Dry as It Heats Up

The latest edition of the ABC 33/40 Weather Xtreme Video is available in the player below. You can subscribe to the Weather Xtreme Video on iTunes by clicking here.

The overall pattern for Central Alabama is stuck in a rut with the combination of surface high pressure situated along the East Coast and an upper level ridge over the eastern half of the country. The ridge will be building stronger over the next several days allowing high temperatures to climb into the lower and mid 90s. We could be verging on the upper 90s as we head into the weekend and early next week.

The upper ridge will build stronger through Friday but then breakdown a bit as a strong trough moves through the Canadian provinces. That trough moves through quickly so the ridge only dampens Friday and Saturday, but it may be enough to bring a front into the Ohio River Valley. There is also a lot of moisture over the Florida peninsula, but it looks like neither of these will get to us but this is our best shot at some isolated showers. I still think while it is our best shot that most of us stay dry.

The ridge builds strong again over the Central Plains behind that trough bringing us back on the edge of the ridge and allowing temperatures to stay in the mid 90s, perhaps verging close to the upper 90s.

SPC has a slight risk for today from Northeast Nebraska into the Upper Peninsula of Michigan ahead of the trough moving through Canada. And the NHC is now watching two areas in the tropics, one in the North Atlantic and another area in the central Caribbean. Conditions do not appear favorable for development of either of these right now.

The GFS and ECMWF models are in good agreement on both position and strength of the ridge especially as we get into the weekend. There have been some differences but they have come much closer together in their solutions.

The ridge weakens somewhat as we head into week 2 and early July. That is certainly a good sign to keep us out of the extreme heat. But the ridge is still with us so we can only hope for the return of some moisture to put scattered showers in the forecast.
