Dry air continues across North Alabama, North Mississippi, and northern Louisiana, so thunderstorm development and clouds are supressed. A weak trough axis across southern Alabama and the Florida Panhandle continued to keep showers active in that area.
The good news suggested by the GFS is that there is no evidence of any high heat in our future. While a large upper level ridge will remain in place into early next week, I don't see any signs of heat higher than the lower 90s that we've been experiencing.
Moisture gradually returns over the weekend so our shower chances will increase to what you might expect in the summertime. A developing shortwave at 500 millibars promises to bring a cold front into the area about Wednesday of next week and into South Alabama by Thursday. While the ambitious nature of this forecast is not out of the question - and would actually be a welcome relief if we could knock 5 to 10 degrees off the dewpoints - I'm a bit skeptical about this becoming fact.
Tropical attention is focused this morning on Harvey passing Bermuda and a rather vigorous area of disturbed weather in the far eastern Atlantic. Harvey is no longer a threat to land, only to shipping. And the forecast for that far eastern Atlantic disturbance is for slow strengthening and a track that would bring it close to the northern Leeward Islands in four days.
Headed downtown this morning to address a group of students from Mississippi State University on my Ivan adventures. Looking forward to that.
Almost Friday - hope the end of your week is going well. Stay cool and enjoy the beauty our atmosphere provides.
