SHORT TERM. /Updated at 1250 PM CDT Wed Aug 04 2021/
Features of Interest.
Broad troughing persists from Southeast Canada that extends south over the Ohio River Valley and across the Tennessee Valley region. Ridging was located over Nevada and over much of the Western Atlantic.
Toward the surface, a weak cold front was draped across the Northern Gulf of Mexico while a weak trough was analyzed from Virginia southwest into Eastern Alabama. Surface high pressure was analyzed to our north over the Midwest into the Eastern Great Lakes region.
No wet microbursts are expected today. While some thunderstorms are forecast, which will produce frequent lightning strikes and heavy downpours, the potential for flash flooding is minimal.
Isolated showers continue to develop with the best chances generally along and east of a line from Oneonta to Birmingham to Selma. This area is in the vicinity of a weak trough toward the surface along with being positioned beneath upper level troughing. Expect the showers to continue to develop through late afternoon with the potential for a few thunderstorms to develop over the next few hours. This activity will move slowly to the east with time.
Expect partly cloudy skies today with isolated showers and a few thunderstorms across the eastern half of the forecast area. Highs will range from the upper 80s northeast to around 90 southwest. Winds will remain out of the north to northeast 5-10 mph.
The core of the deep trough aloft will begin to shift further to the northeast overnight while the surface front remains to our south over the far Northern Gulf of Mexico. An inverted trough from a low along the front will persist across our eastern counties.
Look for shower and storm coverage to decrease through the evening hours with a few showers remaining possible across the far eastern and southeast counties into tonight. Lows will range from the lower 60s northwest to readings around 70 southeast. Winds will be light from the northeast 3-6 mph.
The upper trough will continue to lift further to the northeast while shortwave ridging moves into the Mid South region ahead of a well-defined impulse that will move into the Central Plains. The front will remain across the Northern Gulf Coast while the inverted trough will become positioned across the central portion of the state. Expect isolated showers to develop across the east and southeast from mid to late morning, followed by isolated showers and a few thunderstorms across much of the forecast area from late morning through the afternoon hours. The lower chances will be across the northwestern counties. Highs will range from the upper 80s northeast to around 90 south and west. Winds will be from the east 5-10 mph.
LONG TERM. /Updated at 0245 PM CDT Wed Aug 04 2021/
There were no significant adjustments in the long term forecast. A shortwave trough will traverse the region in the Friday/Saturday time frame. Overall moisture looks to remain on the lower end so only expect isolated to scattered convection with the best chances in the southeast. Next week, we'll see a return to scattered afternoon storms with temperatures in the 90s as high pressure settles in over the region. We'll have to keep a close eye on heat indices as well.
Previous long-term discussion: /Updated at 0236 AM CDT Wed Aug 04 2021/ Friday through Tuesday.
A relatively amplified (by August standards) shortwave trough will move eastward from the Lower Mississippi Valley Friday afternoon. The wave will be moisture-starved until it begins to cause the old frontal boundary and associated moisture to lift northward. There still continues to be a lot of spread in the models and ensembles regarding this moisture return and whether a wave of low pressure develops along the front, with some models also suffering from apparent convective feedback issues. For now the consensus places the relatively highest PoPs in the southeast counties Friday afternoon through Saturday morning. Subsidence develops behind the shortwave from west to east by Saturday afternoon, likely diminishing rain chances. Ridging builds across the Deep South Sunday through the rest of the period, a more typical synoptic pattern for this time of the year, and the front dissipates. This will result in temperatures returning to near normal, with moisture gradually increasing as well. Coverage of diurnal convection will be dependent on weaknesses in the ridge, but should remain scattered in nature. Heat indices will also creep up into the 100 to 105 range early next week.
AVIATION. 18Z TAF Discussion.
Isolated showers with a few thunderstorms are forecast across the eastern and southern portions of the forecast area today as a weak trough is positioned across the eastern portion of the state. Carried VCSH at all sites but TCL and included a 21z-00z TEMPO for TSRA for ANB/ASN/EET/MGM/TOI where chances will be best. Low- level winds will remain generally out of the north 4-8 kts. Expect most sites to be dry overnight under fair skies with light northeast winds 2-4 kts. Isolated showers with a few thunderstorms are forecast on Thursday with all terminals having VCSH included from 15z onward with TS potential increasing beyond 18z.
Showers and storms will remain isolated to widely scattered at most through the rest of the week, with relatively highest chances east and minimal chances west. RH values will remain above 40 percent through the forecast period.
