.SHORT TERM...

Today and tonight.

Looking at the overall synoptic pattern across the area, a front is 
draped across Central Alabama. Convection is limited to an outflow 
boundary that moved through the area earlier Saturday evening. 
Meanwhile, a large upper low is centered over the Ohio Valley and 
beginning to slip down toward Tennessee. To emphasize the extent of 
the upper lows impact, feeder bands into this low can be observed on 
IR satellite stretching across the Atlantic and down to near Cuba. 

So for today, the main upper low will begin to drift toward the 
south and begin to impact northern Alabama this afternoon. The cold 
front will slowly slide south at the same time. As it slides south, 
it will also pivot to more of a southwest to northeast orientation, 
in conjunction with the upper low. Rain chances for today will be 
highest in the south ahead of the front, as well as in the northeast 
as the upper low moves in. Activity will likely be more rain showers 
than thunderstorms in the northeast, while activity in the south 
will be mainly thunderstorms. There could be a stronger storm late 
morning and into the afternoon in the southeast in advance of the 
front, but severe potential remains too low to mention at this time. 
Temperatures today will generally be in the 80s north of the front 
and 90s south of the front. 

As we move into tonight, the rain chances in the south will diminish 
by Midnight, at the latest, as the front clears. Activity in the 
northeast will likely continue through the night, with generally a 
scattered nature. Again activity will likely be more showers with a 
rumble or two of thunder. Temperatures overnight will be in the 60s 
north and central, with some lower 70s in the south.

.LONG TERM...
Monday through Sunday.

The overall synoptic pattern doesn't change much through the first 
half of this week. The strong ridging over the Southwest US persists 
as the deep longwave trough is over the Eastern US. The upper low 
tries to become cut-off over the Gulf States on Monday, but 
eventually does get phased back in with the upper trough Tuesday 
into Wednesday. Expect synoptic scale lift associated with the upper 
low to provide increased rain and thunderstorm chances for Central 
AL, especially the eastern two-thirds of the area. We normally don't 
have this type of large-scale forcing in the summer months, so 
thunderstorm coverage will be a little more widespread. Therefore, I 
have gone with generally 60-70% PoPs each afternoon through 
Wednesday. 

Around mid-week, another strong low pressure system moves through 
Manitoba and into Ontario, which acts to lift the troughing over the 
Gulf States northeastward into New England. A remnant frontal 
boundary will likely remain stretched southwestward along the 
East Coast through the second half of the week, but models 
disagree on exactly where this will become stationary. The current
GFS has the stationary boundary setting up through the 
Appalachians and into Central AL, which would lead to continued 
rain chances through at least Saturday or Sunday. However, the 
ECMWF keeps more along the East Coast, so the best convergence is 
south and east of us, allowing us to have more of a typical 
summertime diurnal pattern. For now, have split the difference in 
PoPs for Thursday through Sunday until we know more about where 
the boundary will set up. 

Temperature-wise, we should have more of a moderated daily range 
considering the increased cloud cover, rain chances, and overall 
cold core nature of the upper low. Towards the end of the week, I've 
started a warming trend, but that will again be dependent on how the 
remnant frontal boundary behaves.

as a result the shock from the lightning bolt was passed from one animal to
another. (David Ludlum)
...1986...
Hurricane Estelle passed 120 miles south of the Hawaiian Islands creating a
ten to twenty foot surf. The large swells resulted from a combination of
high tides, a full moon, and 50 mph winds. The hurricane also deluged Oahu
Island with as much as 6.86 inches of rain on the 24th and 25th of the
month. (Storm Data)
...1987...
Barrow AK receives 1.38 inches in 24 hours on the 21st and 22nd, an
all-time record for that location. The average annual precipitation for
Barrow is just 4.75 inches. Thunderstorms in Montana produced 4 to 6 inches
of rain in Glacier County causing extensive flooding along Divide Creek.
Missoula MT received 1.71 inches of rain in 24 hours, a record for the
month of July. (The National Weather Summary) (The Weather Channel)
...1988...
Six cities in the south central U.S. reported record low temperatures for
the date, including Pueblo CO with a reading of 48 degrees. Thunderstorms
over the Atlantic Coast Region drenched Wilmington NC with 6.49 inches of
rain in about eight hours. (The National Weather Summary)
...1989...
Showers and thunderstorms prevailed across the southeastern third of the
country. Afternoon thunderstorms in Florida produced wind gusts to 86 mph
at Zephyrhills, and gusts to 92 mph at Carrollwood and Lutz. Thunderstorm
winds gusting to 69 mph at Crystal Lake damaged nineteen mobile homes.
