become active later on this morning and into the afternoon. A 
fairly strong cold front for this time of the year is currently in  
the Southern Plains and stretches to a low pressure system almost 
on top of Kansas City. There is a 1020mb high pressure system in 
the Atlantic, with a 1027mb high pressure system sliding down into
the High Plains. This pattern will continue to provide 
southwesterly flow into the area through the day and will result 
in a good coverage of scattered to numerous showers and storms 
this afternoon. Meanwhile additional showers and storms will 
develop along the front itself as it begins to approach the area. 
A few stronger storms can be expected with the activity in the 
afternoon over the area, but most of the activity will be sub 
severe as cloud cover and lack of instability should keep things 
under control. 

As we move through the late afternoon/early evening, the stronger 
activity will be along the front as it moves through MS and TN. We 
will need to keep an eye on this activity as it begins to work
into the region. Stronger storms will be possible along the 
line, and depending on the trend and timing a few stronger storms 
may work into the far northwestern counties before 10 pm. There is
quite a nit of difference in timing and thus strength of this 
activity through the next 24 hours, so confidence is not high 
enough to include the mention of severe storms at this time, as 
the front should remain just to our west through the short term. 
The one thing the models do agree on in that as the activity works
into the area it weakens fairly quickly, especially if the area 
does get worked over this afternoon. Further evaluation will be 
done this morning once the latest models and upper air get into 
our system.



Tuesday through Sunday.

A surface cold front will sweep across Alabama on Tuesday into 
Tuesday night as a relatively strong upper-level trough moves 
from the Ohio Valley toward the East Coast. The forward speed of 
this system continues to trend slightly faster in the newest model
runs, and the highest rain chances have been shifted farther 
southeastward beginning at 12Z Tuesday. Due to the lack of daytime
heating, activity along the front may be at a relative minimum as
it passes through the I-59 corridor in the mid to late morning 
hours. Convection should increase along the front during the early
to mid afternoon along and south of I-85. 

A much drier airmass will overspread the region Tuesday night and 
remain in place through Thursday. Morning temperatures should fall 
into the low to mid 60s for many locations in our northern
counties with upper 60s elsewhere.

The development of deep-layer easterly flow is likely to cause a 
moistening trend on Friday and into the weekend. This may mark the 
end of the rain-free period with a return to daily afternoon and 
evening convection focused along and south of I-20.

Historical Weather And Climate Facts For Today

The town of Indianola TX was completely destroyed by a hurricane, and never
rebuilt. (David Ludlum)
The "big blow up" of forest fires finally came to an end in Idaho. A record
dry August fueled 1736 fires which burned three million acres destroying
six billion board feet of timber. The fires claimed the lives of 85
persons, 78 of which were fire fighters, and consumed the entire town of
Wallace. The smoke spread a third of the way around the world producing
some dark days in the U.S. and Canada. The forest fires prompted federal
fire protection laws. (David Ludlum)
Half a dozen cities in the Central Plains Region reported record high
temperatures for the date, including Pueblo CO with a reading of 102
degrees, and Goodland KS with a high of 104 degrees. Hill City KS reached
106 degrees. (The National Weather Summary)
Sheridan WY reported a record hot temperature reading of 100 degrees.
Evening thunderstorms produced golf ball size hail near Fortuna ND, and
wind gusts to 70 mph near Webster SD. (The National Weather Summary) (Storm
Early morning thunderstorms produced heavy rain in southeast Kansas and
northeastern Oklahoma, with up to six inches reported around Tulsa OK. Some
roads in the Tulsa area were closed by water 10 to 12 feet deep. Evening
thunderstorms produced severe weather in northern Oklahoma and southern
Kansas. Thunderstorms produced winds gusts to 75 mph in Major County OK,
and hail two inches in diameter at Jennings KS. (The National Weather
Summary) (Storm Data)
