SHORT TERM
(Today through Tuesday Night)
Issued at 302 AM CST Mon Dec 4 2023

Today is National Cookie Day and with the weather throughout the short term period being a sweet treat...let's have some fun! See if you can catch all of the cookie puns sprinkled in...there are a lot of brownie points up for grabs! Upper level clouds continue to stream overhead along and south of I-10 as we remain close enough to a jet streak and a stream of PVA from shortwaves extending from northern Mexico to the Upper Texas coastline. We forgot the cooking spray though, so the upper level clouds will stick around into tonight even with a cold front pushing offshore by the mid morning hours today. This will be a dry FROPA as PW values remain in the 0.3"-0.4" range (10th percentile: ~0.36"), so it'll stay nice and crisp out there. You'll fill a difference this afternoon dough with temperatures slightly cooler than Sunday's with highs topping out in the mid to upper 60s. That's just the first of two cold fronts that push through early this week...it keeps getting batter and batter!

Surface high pressure drifts overhead today and remains in place tonight. The upper level clouds south of I-10 begin to crumble overnight as the previously mint-tioned stream of PVA nudges southward. So, we'll have light winds and clearing skies with CAA prevailing...that's a slam dunk recipe for max radiational cooling! Expect low temperatures to bottom out in the upper 30s to upper 40s.
Coming up on Chews-day, another mid/upper level trough dips down into the Upper Midwest with its associated surface low drifting southeastward from the Dakotas to the Great Lakes region. This will lead to another weak FROPA on late Tuesday afternoon/evening bringing us s'more CAA going into Tuesday night. It's worth noting that we catch the tail-end of the second front, so the main batch of colder air will remain to our northeast. Ahead of the front on Tuesday afternoon, we'll still see temperatures reach the upper 60s to low 70s. With skies finally cleared out for all of Southeast Texas on Tuesday night and a ~1030mb surface high pressure moving in leading to light winds again, I decided to take a calculated whisk and trend a little bite cooler. Expect low temperatures to be a degree or two cooler than Monday night's.

Speaking of Tuesday night, this is when mid to upper level ridging begins to chip in from the west. That sets the stage for raisin temperatures going into the long term period...but they don't look to get high enough to get us into baking territory! Hopefully I didn't fudge the numbers while counting things up, but if you counted 24 puns then you got em all and earned the title of "one smart cookie"!

LONG TERM
(Wednesday through Sunday)
Issued at 302 AM CST Mon Dec 4 2023

Surface high pressure ridging into the area from the north at the start of this period will gradually work its way eastward through the end of the week. Northeast to east winds on Wednesday will become southeast to south through the end of the week resulting in a warming trend. Moisture levels will also be on the rise from this onshore flow, and rains will come back into the forecast mainly from late Friday night through early Sunday morning. The latest forecast has the next cold front moving across the area during the day on Saturday. Cooler and drier weather accompanied by breezy northwest to north winds can be expected Saturday night and Sunday behind this front.

The high temperature trend has readings in the 60s on Wednesday increasing to mainly 70s on Thursday, Friday and Saturday. Behind the front on Sunday, we'll indicate highs in the 50s/60.

The low temperature trend has readings in the 40s Wednesday night increasing to the 50s/60s on Thursday night and Friday night. Behind the front on Saturday night, we'll indicate lows in the 40s.

AVIATION
(18Z TAF Issuance)
Issued at 1118 AM CST Mon Dec 4 2023

Fair weather the rule this cycle as high pressure comes to dominate the area. VFR throughout, with no more than partial cirrus, particularly at the coast. North to northeast winds around 10 knots (with an occasional gust into the upper teens) this afternoon, becoming light and more variable - generally between northerly and easterly - overnight and early tomorrow morning.
Winds should come back to more northerly afternoon, but only included this explicitly in the IAH extended.

MARINE
Issued at 302 AM CST Mon Dec 4 2023

Mainly light northeasterly winds and low seas will persist through at least midweek, becoming southerly and increasing (seas rising too) by the end of the week. Winds could occasionally flirt with caution speeds.
Look for a cold front (and associated showers/storms) to move off the coast and through the area on Saturday with strong northwest winds and building seas in its wake (advisories will likely be needed).
