New AVIATION

UPDATE
Issued at 842 PM CST Fri Dec 1 2023

As of 915 PM CST, a slow-moving frontal boundary continues to maintain cloud cover over the southeastern two-thirds of the forecast area, producing a corresponding effect upon temperatures.
This includes lower 40s north of I-30, and mid-60s south of I-20.
This round of showers and isolated thunderstorms will linger across north-central Louisiana overnight near the frontal boundary while patchy fog is likely to develop nearly areawide as a result. With weather and observed trends continuing as anticipated, forecast grid adjustments were not necessary at this time. /16/

SHORT TERM
(This evening through Saturday Night)
Issued at 229 PM CST Fri Dec 1 2023

Fair skies unfolding for much of our Four-State area with some elevating stratocu S of I-20, lifting into the lower mid levels from Lufkin to Monroe soon. Meanwhile, cold air stratocu is holding position just edging into McCurtain County. There a strip of high clouds over Texas and OKlahoma that will drift over our I-30 corridor tonight. So clouds will be good in limiting fog formation. However, decided to go with widespread patchy after midnight with ground still cool and damp. Lows will be dropping to within a few degrees of dew points and model guidance remains split from light to dense in some cases. Rainfall will be light and exiting to the SE early on Saturday.

The soon to bring light rain clouds are thickening now over the Rio Grande and Texas coastal bend with a jet speed max and will shift overhead for our deep east TX counties, S central AR and all parishes overnight. Any QPF from middeck is generally light, and thats about all we will be adding to start the new month after some decent totals to end Nov anyway. Even though it was a dry month for most. This thickening of clouds will bring a tenth or two at most from Toledo Bend Country over into NE LA overnight.
Lows will sport a healthy diagonal gradient from SE OK with a few upper 30s or DeQueen with middle 30s, to even some lower 50s in the Monroe and Jena vicinities. In fact this diagonal swath of clouds will linger into much of tomorrow and tomorrow night as well with highs seeing a range of 60s from the cooler NW to warmer SE. Finally tomorrow evening will see skies clearing out areawide with a cooler range of 30s and 40s expected in the predawn hours on Sunday. /24/

LONG TERM
(Sunday through next Thursday)
Issued at 229 PM CST Fri Dec 1 2023

After some much needed rainfall over the past few days, a splendid long-term forecast is in store throughout the upcoming work week.
Beginning Sunday, a weak shortwave will traverse through the Central Plains into the Mid-MS Valley and help usher another weak cold front across the region on Sunday night. This cold front will serve as a reinforcement of the dry air mass in place and return to seasonable temperatures into early next week after slightly above normal highs with most areas generally ranging from the mid 60s to lower 70s on Sunday afternoon.

Behind the cold front, look for a gradual transition to more NW flow aloft into mid week as the longwave trough shifts across the eastern CONUS. Within the NW flow pattern, another weak cold front will work across the region on Tuesday into Tuesday night with little fanfare.
Once again, it will more or less serve to reinforce the mild and dry air mass in place with dry conditions expected to prevail through the end of the week. Expect daily highs generally in the 60s with lows in the 30s and 40s, quite seasonable for the first full week of December. /19/
