As we described yesterday, the front made its way through much of Alabama overnight with a fairly nice rain for many locations but not everyone got a good rain. I recorded only 1 hundredth of an inch, so I was one of those spots that got missed. However, I was at The Summit yesterday afternoon where a small but intense shower produced a drenching downpour for about 15 minutes.

The drier air lagged behind the front somewhat. Dew points were still in the lower 70s from Birmingham south while north of Birmingham values were in the 60s. That drier air will continue to filter into Central Alabama today, so even with a high of about 90 it will feel a little better as the humidity levels fall somewhat.

Dry air and a slight northwesterly flow aloft will continue through much of the upcoming week. We should start each day in the 60s with Monday being our coolest morning. Monday some cooler spots are likely to drop into the upper 50s. But those highs will continue to reach the 90s – mostly 90 to 93 or so.

The pattern changes very little through the upcoming week. By Friday a weak front should be approaching providing the conditions for some isolated showers. Again, not everyone is expected to get rain. But the front will wash out by Saturday with no real air mass change – just some slightly drier air.

Tropics remain quite active with four areas to be watched. Igor has become a hurricane – 4th of the season. Igor is expected to recurve into the open Atlantic but could be a big threat to Bermuda. The area of disturbed weather in the Caribbean continued to march along to the west-northwest. While there are numerous thunderstorms evident on the satellite imagery, the area continued to be disorganized. Conditions do appear favorable for some organization. The track suggests strongly that the area of storms will get into the Gulf, so this one will bear a lot of watching.

Far out in the Atlantic in the vicinity of the Cape Verde Islands is another area that appears quite likely to become a depression in the next 24 to 48 hours.

Further out in time, the GFS continues to show the ridge over the eastern half of the country. This suggests no air mass change for the foreseeable future as the heat continues to roll along.
