...New UPDATE...

.UPDATE...
Issued at 1031 AM CDT Fri Oct 7 2022

As of 10:30 AM CDT, temperatures remain in the low-to-mid 70s
across the Ark-La-Tex with high clouds drifting in from the west
as a trough over the Gulf of California funnels southwesterly 
flow aloft. Temperatures will steadily warm up to maximums in the 
upper 80s (with lower 90s possible) on an otherwise dry day. With 
weather and observed trends continuing as anticipated, forecast 
grid adjustments are not necessary at this time. /16/

.SHORT TERM...
(Friday through Saturday)
Issued at 152 AM CDT Fri Oct 7 2022

Cry Havoc, and let slip the temperatures of fall! 

For starters, I don't believe that Shakespeare quote to be
entirely accurate. Beyond that, it's not entirely accurate from a
meteorological sense either. While we can expect a swing in
temperatures towards an autumn feel, it's really only a feel of
the seasonal kind. A trough will continue to dig through the
Midwest at the start of this short-term, which will push a pretty
powerful cold front south with it. The region won't really begin
to feel the effects of this front until Saturday, with afternoon
highs getting down into the mid-70s to mid-80s. Until then,
temperatures under the dry airmass will continue to run above
average. Highs today will range in the upper-80s to low-90s, with
lows tonight ranging in the low-50s to low-60s.

Rain chances....well...we won't talk about those. Well, I will,
but you won't like what I have to say. While this is a very beefy
cold front expected to move through into the weekend, the airmass
situated over the region is bone dry. This will once again result
in a dry frontal passage, with rain chances remaining limited well
into the long-term.

.LONG TERM...
(Saturday Night through Friday)
Issued at 152 AM CDT Fri Oct 7 2022

Post FROPA continues through the weekend as the ridge axis settles 
in and works to the south and east. The 10 degree high temperature 
spread forecasted for Saturday will return back to low to mid 80s on 
Sunday as return flow settles in late Sunday night into Monday 
morning with sfc winds becoming southeasterly. The return to 
southerly sfc flow will aid in an increase in temperatures to start 
the new week as mid to upper 80s appear likely in this forecast 
package. Best chances for low 90s look to be to the southwest, 
closer to Lufkin (KLFK). 

As the ridge axis continues to work east and depart 
the Delmarva Peninsula, into the Atlantic between 15-18z Tuesday, 
southeasterly winds will prevail locally ahead of an expected 
frontal passage highlighted in the global guidance for Thursday 
morning/afternoon. Timing of the frontal passage, along with FROPA 
associated POPs, will dictate just how warm high temperatures get 
Thursday. For now Wednesday should represent peak warming ahead of 
the front. Post frontal temperature advection will allow for another 
return to seasonal highs near the end of this forecast cycle.  

Models continue to highlight healthy moisture advection northward 
from the Gulf of Mexico (GOM) Wednesday ahead of the arrival of the 
frontal boundary some time between 12-15z Thursday. Increased PWAT 
values nearing 1.50" across central LA, mixed with convergent flow 
ahead of the front will help support some minor POPs Wednesday 
afternoon in the far SE corner of the CWA, with more widespread POP 
chances Thursday as the front moves in and PWAT values advance 
further north. While the trend of frontal associated POPs continue 
to appear in the guidance, forcing associated with the front looks 
to decay on approach to the northern fringe of the CWA, but still 
enough to support the chance for showers Thursday. For now, keeping 
the NBM long term rain chances in this forecast cycle. Following the 
passing front, the associated ridge axis behind the front sets up 
across central Arkansas for the end of the forecast period, drying 
us out once more.
