Our weather pattern will continue to be active for the foreseeable future with some pretty good chances for rain today and Monday thanks to the approach of a weak front. SPC even suggesting potential for severe storms especially in the Tennessee River Valley today and tonight with damaging wind and marginal severe hail possible.

The strong trough moving across the Great Lakes will be responsible for dragging a cold front into the Tennessee River Valley today and Monday. In the upper atmosphere, the Bermuda High to the east and the persistent ridge to our west will connect today, however, the connection is short-lived as another strong trough moves in quickly behind this first one to help to reestablish the trough over the eastern US. At the surface, there is the front approaching from the northwest which should help to add thunderstorm development in the heat of the day plus a weak inverted trough moving toward the west across the Gulf coast. So two distinct features each helping to improve rain chances for the northern and southern sections of the state.

This means that we should stay in a fairly active pattern for the next week or so with rain chances up due to the presence of the frontal boundary plus we get back into a northwesterly flow pattern. The atmosphere does not change much so we remain moist for daily shower chances.

Rainfall amounts are likely to be between 2 and 3 inches for some locations during the next 5 days. As we noted yesterday, many of the storms were slow moving resulting in heavy rainfall in isolated locations. The relatively slow movement of storms should keep this threat with us for the next several days, too.

Tropics are active with Florence and Ernesto. Florence defies forecasters by maintaining herself, but she remains a threat primarily to open waters of the Atlantic. And Ernesto continues to chug steadily across the Caribbean with some weakening. Ernesto seems to have a bead on the Yucatan Peninsula and could become a hurricane before reaching the coast there. Current guidance continues to show a slightly more southerly track which would bring the storm into the southwest Gulf of Mexico on Thursday and Friday. My concerns for the troughiness over the eastern US are not as high with a slightly more southerly track, but I am still wary of how the two might interact as they get closer. So for now it looks like the western Gulf remains the primary risk area.

Looking into voodoo country, the GFS shows a messy pattern with a continuation of the western ridge and a sizable storm in the Atlantic around August 20th.
