Today through Tonight...

Today: Water vapor/RAP imagery indicate >590DM ridge centered over 
the Bay of Campeche, while quasi-zonal flow persists across the 
region. Broad cold core/sfc low & frontal system are moving into the 
Hudson Bay area, with another sfc low moving into the OH Valley. 
This is bringing a cold front towards the area, where a few radar 
returns persist across the Mid-South in southeast AR & northern 
MS. Can't rule out a stronger storm sliding into the Hwy 82 
corridor over the few couple hours but likelihood is diminishing.
Main concerns remain for low stratus/dense fog this morning. 
Warm, moist southwesterly flow gradually becomes westerly as the 
sfc low swings into the OH Valley. There has been some vsby drops
across the Hwy 45 corridor with patchy fog, while dense fog along
the I-59 corridor up to Lauderdale County area. Main adjustments 
were to add an "Elevated" for areas of dense fog in the HWO 
graphics along & southeast of a line from Lincoln-Newton/Lauderdale
Counties, while an adjacent "Limited" along & east-southeast of a
line from Adams-Simpson-Neshoba-Oktibbeha/Clay counties. HREF 
probs have been persistent for some dense fog so made that 
expansion in the HWO graphics. This will persist through mid- 
morning around 9AM. As the front sinks south, expect a gradual 
improvement in low stratus/fog into the day. Rain & isolated storm 
chances will dwindle & remain confined to east-northeast MS. 
Winds will shift more northerly around daybreak in the Delta to 
mid-afternoon northwest of the Natchez Trace. Highs will be 
seasonably cool, in the low- mid 70s, in the wake northwest of the
Natchez Trace corridor, while seasonably warm, some +5 deg F 
above normal, to the southeast in the low-mid 80s. Locales in the
Pine Belt could eclipse the 90 degree mark.

Tonight: As broad cold core low/sfc frontal system swing into the 
Hudson Bay, frontal zone is expected to slide southeast through the 
Gulf Coast states. Northerly winds will build in, but this front 
won't be a good clearing of deep moisture. It will clear out rain 
chances briefly, before increased isentropic showers & possibly a
few rumbles of thunder build back into the ArkLaMiss Delta before
daybreak. Persistence will be the case for fog, with the Hwy 84 
to I- 59 corridors, south of I-20, having the best chance for 
patchy to patchy dense fog. For now, did not introduce dense fog 
but another round of dense fog is probable. Will hold off any
graphics during this fcst package but may be needed later. 
Seasonable lows in the mid-upper 50s are expected northwest of 
the Natchez Trace, while seasonably warm to the southeast, in the 
low-mid 60s. /DC/

Saturday through next Thursday...In the wake of a cold front, a 
couple of disturbances will shift east across the region in zonal 
flow during the upcoming weekend. This will result in decent chances 
for showers, along with an isolated thunderstorm or two, across the 
forecast area Saturday and again on Sunday.  Cooler drier air will 
also advect into the region during this time.  Look for highs on 
Saturday to range from around 60 to the upper 70s, and then in the 
60s on Sunday.  Lows Saturday night will be from the upper 40s to 
middle 50s.  Then noticeably cooler conditions will be seen Sunday 
night, as lows cool into the low and mid 40s areawide.

As the final disturbance exits the region late Sunday, northerly 
winds will persist as high pressure to the northwest builds into the 
forecast area.  Quiet weather and drier air will exist across the 
region Monday into Tuesday.  While conditions will steadily warm 
through mid-week, another weak frontal boundary is currently 
forecast to sink south into the forecast area late Wednesday into 
Thursday.  At the moment, little to no chance of rain is expected 
across the area.  However, this will bring an increase in cloud 
cover across the CWA. /19/
