pressure at the surface. Looking at Water Vapor imagery this 
morning, there is an increase in moisture across the southeast. At 
the same time, looking at IR imagery, there appears to be a weak 
boundary just to our south. Meanwhile, the main storm system remains 
well to our west. As the ridge and surface high nudge to our east a 
little bit more today, the flow will become more southerly. So even 
though the overall airmass will remain dry for the day, there will 
be some factors that could allow a shower/storm to develop. With the 
warmer temperatures, an increase in moisture in the overall 
environment (as seen on WV), and the boundary (as seen on IR) 
forecast to rotate around the high pressure system, there is a 
chance at seeing an isolated shower/storm across the northern and 
eastern portions of the area this afternoon. Highs will be in the 
90s, with lows in the upper 60s to low 70s.

Tuesday and Wednesday.

* Record high temperatures possible through Wednesday.

* For specific information on record high temperatures and record 
  warm lows for the four Central Alabama climate locations, please 
  refer to the Climate section at the bottom.

Hot temperatures are expected to continue through Wednesday with low 
to upper 90s for afternoon highs. The deep-layer ridge should begin 
to weekend with low-level anticyclonic flow positioning more to our 
southeast, however. This may help draw in a little more low-level 
moisture from the Gulf. To our northwest an upper-level disturbance 
will meander across the Central plains with southwesterly flow aloft 
stretching from Texas to the Ohio Valley. This will help keep 
forcing for ascent & storm tracks out of our area which keeps rain 
chances very limited until Thursday. Overnight lows in the mid 60s 
to lower 70s and patchy fog will continue.

Thursday through Sunday.

The synoptic pattern across the CONUS will begin to transition as we 
head into late-week. The persistent blocking ridge across the 
Southeast will continue to weaken/flatten as the aforementioned 
trough moves towards the Great Lakes region. This system is progged 
to elongate and weaken as it is absorbed into a more significant 
longwave trough across Quebec. As a result, quasi-zonal flow will 
take hold of the area by the weekend. Effects from the remnant 
diffuse frontal boundary will be felt Thu/Fri with rain chances on 
the rise from associated lift & moisture increases. Trends with this 
have been fairly consistent though still lack high confidence on 
specific details other than scattered thunderstorms could be 
anticipated on those respective afternoons. Fortunately, this will 
bring some relief from the heat and dry conditions with needed 
rainfall. Have kept PoPs <30% for now due to the weakened nature of 
the front and associated lift, as well as the expectation that PoPs 
will be more diurnally driven with the forecast summer-like airmass. 
Otherwise, afternoon highs Thu-Sun are forecast in the upper 80s to 
mid 90s in our typical warm spots with isolated rain chances 
continuing into the weekend.

...1896...
A massive tornado struck Saint Louis MO killing 306 persons and causing
thirteen million dollars damage. The tornado path was short, but cut across
a densely populated area. It touched down six miles west of Eads Bridge in
Saint Louis and widened to a mile as it crossed into East Saint Louis. The
tornado was the most destructive of record in the U.S. up until that time.
It pierced a five-eighths inch thick iron sheet with a two by four inch
pine plank. A brilliant display of lightning accompanied the storm. (David
Ludlum) (The Weather Channel)
