.DISCUSSION...
Tonight and Friday: 

Continued cooler than normal and dry through the short term. 
Afternoon surface analysis had a weak cold front drifting into the
central portions of the CWA. This cold front was losing its 
momentum as it has become nearly parallel to the upper level 
winds. The cold front is still expected to push southeast of our 
area this evening as a surface high centered over the Central 
Plains this afternoon shifts east through Friday. This will result
in shallow cool air beneath mid level flow that will back a 
little further to the southwest tonight. Satellite imagery showed 
mid and high level clouds streaming across the southern half of 
our CWA this afternoon. Models suggest our CWA will remain in the 
favorable quad of a jet streak that will strengthen to >150kts by 
Friday morning. Although no precipitation is expected in our CWA 
the cloud cover will continue through Friday and limit insolation.
This will hold afternoon highs in the 50s again. Friday morning 
lows will be cooler than normal as well with lows in the 30s 
areawide. /22/

Friday night through Wednesday:

As we go into the weekend, expect a chaotic upper pattern as a
longwave polar trough will be moving through the Great Lakes while
two distinct closed shortwaves will be diving into the Great Basin
to over western Mexico. This will only help slowly increase
moisture & clouds as we go into the weekend. By Friday night, the
mid-level ridge axis will be slowly moving towards the area while
PWs will only be around a quarter of an inch or so. The surface 
ridge axis will be centered off along the Atlantic seaboard. This 
will help south-southwesterly return flow to slowly develop & 
moisture will only be slowly moving in by that timeframe. Thus 
expect a cold and chilly night (~5-10 degrees below normal) near 
freezing to just below in the northeast. As the the shortwave 
trough swings into southern Texas on Saturday, the ridge axis will
move directly over the area and expect near normal highs warming 
into mid-upper 50s. As isentropic lift slowly increases, mid-high 
clouds will increase in coverage.

By late weekend on Sunday, expect the ridge axis to shift east & 
southerly return flow to bring back in better moisture into the 
area. This will help a cold front with decent low-mid level wind 
flow to propagate through the area. PWs will increase to around an
inch and a half to inch and three quarters. Right now it looks as
though most destabilization will remain off to our south & the 
surface low development looks to move through most of the central 
portions of the area. With around 30-40kts 0-3km bulk shear, can't
rule out a couple stronger storms in the south but overall 
organized convection is not expected. This looks to bring enough 
moisture & moisture transport into the area to bring some 
potential for some heavy downpours, possibly upwards of an inch or
so. This will help make some of a dent in rainfall deficits 
across the area. 

Expect this shortwave trough to swing through by Sunday night. 
However, this persistent southwest flow pattern will continue 
through most of next week. This will help moisture & rain chances 
to linger through the work week. The main difference looks to be 
around mid- late week as the Euro is less phased, which keeps the
rainfall chances lingering through the period. This airmass will 
also keep clouds & cooler temperatures but with increasing thermal
profiles, can't rule out temperatures reaching the mid-upper 60s 
or so (~8-10 degrees above normal). Went slightly cooler for highs
around early portions of the week but due to increasing warm air 
advection, still could warm efficiently. Also lows seemed too cool
as there is significant spread in the ensembles/guidance on 
phasing of the trough & timing of the cold front moving through. 
Due to that, trimmed lows around 3 degrees or so towards the MOS 
ensemble means but would not be surprised for this to slowly 
increase due to moisture, rain & clouds around. By Wednesday, if 
the pattern is less phased (which this package was leaning towards
with the Euro), we could have some showers mainly along & south 
of I-20 on Wednesday. /DC/
