Discussion... 


Upper level low pressure system will continue to slowly move to 
the east this afternoon and evening. A short wave riding along the 
base of the low should produce one more shot of light rain 
tomorrow. 


Dry conditions will prevail during the early parts of next week. 
However...with a northwest flow aloft expected to remain in place 
for much of the week...expect for a couple of more upper level 
systems to move across the area. First disturbance will ride along 
the northern Gulf Coast which should keep US rain free. The second 
and a much stronger system will move across the area on Thursday 
which should bring another good chance of rain. 


This system will quickly exit as yet another upper level trough 
begins to set up over the Midwest. Although is still a long way 
out...long range computer models are already showing good upper 
level dynamics with this incoming system. As we get closer and 
closer to Spring...we will need to watch these system a little 
closer. Still plenty of time to see how this system takes shape. 


Temperature wise...expect for them to range in the 60s for highs 
and 40s for low for much of the entire period. No significant 
cool Downs thankfully.

Aviation...00z taf discussion. 


Scattered shower activity and gusty winds will continue to move 
across the area over the next few hours. Activity should not have a 
significant impact to any terminals...and will diminish through the 
evening hours. Expect lowered ceilings overnight with light westerly 
winds. Another weak upper level shortwave will cross the area 
tomorrow. Scattered shower activity will redevelop across the north 
after 15z.
