Time to start a February weather thread will winter hang aroung or spring start early?

Looks pretty seasonable on GFS, GEM, ensembles with a potential Gulf low late next week...

I wouldn't be surprised to see one more arctic front in February seeing there was one in December and one a few weeks ago, but that maybe is it. The pattern has been a lot more days warm compared to cold days. I don't mind days like this with sun and nice weather!

Seeing indications of a significant pattern change as February begins. Several Hemispheric features suggest the jet stream buckles and potentially sends a February chill heading S along and East of the Rockies. Time will tell.

The overnight guidance suggests a stalling frontal boundary draped across Central Texas on Thursday will bring increasing clouds and the potential for some light rain Thursday afternoon into the early part of Super Bowl Weekend. It appears a shortwave with a attending Pacific frontal boundary may push across the area Super Bowl Sunday with a chance of showers and possibly a few thunderstorms, but the best chance for heavier rainfall appears to be NE of Metro Houston with local rainfall amounts of a quarter to a half inch possible for our Super Bowl festivities.

Winter Cancel.

Now praying for a long cool spring and cooler summer if we cant have winter here in se texas!

I see nothing to indicate a major pattern reversal in February. We'll end January about 7 degrees above-normal. Superbowl weekend is looking mild and generally dry. Lows in the lower 60s, highs in the mid 70s. Doesn't get much better than that in early February.

I would not write winter off yet........ It can get cold into March.

Another mostly sunny and warm day ahead across SE TX with onshore winds beginning leading to increasing moisture. Patches of fog possible tonight and Wednesday morning; as well as, Wednesday night. Increasing clouds Wednesday followed by a 20-30% chance of showers Thursday into the weekend.

Let's see what Punxsutawney Phil has to say...

The afternoon deterministic GFS and ECMWF solutions suggest a big Central North American full latitude trough ushering in some chilly air around the middle of next week. It's still too soon to know with any certainty exactly what our sensible weather will be since the models have been struggling with the Hemispheric Pattern, so we will continue to monitor the trends.

Wednesday morning briefing from Jeff:

Extremely nice late January/early February weather to continue for a few more days.

Zonal upper air pattern allowing a fairly straight forward forecast…mainly a temperature forecast. Low level moisture has been on the increase over the last 36 hours as winds have returned to onshore and this is resulting in a few more low level clouds and warmer overnight lows. Temperatures will continue to run well above early Feb. averages with lows in the 60’s and highs near 80. Onshore flow will continue into Friday before a weak cold front moves across the area. Temperatures look to cool back toward normal behind the front with lows in the 50’s and highs in the 60’s under mainly cloudy skies Friday and Saturday.

A storm system will eject into the central plains and upper Midwest over the weekend, but latest model guidance is suggesting the main dynamics will remain well north of SE TX and models have been trending drier and drier with each run for the weekend. Expect the old cool front to begin to lift northward late Saturday into Sunday which will bring a warmer air mass back into the region for Sunday. Will maintain a 30% rain chance for Saturday and Sunday for a passing shower especially with a boundary over the area, but think much of the area will remain dry.

Climo and cold air in Siberia Alaska suggest we'll see probably 1 maybe 2 more outbreaks of cold in February to the beginning of March with longer periods of zonal warm weather...par for this "winter."

Having said that we've had the coldest night in about a decade in College Station, and some changeable and windy days. It's possible that climate changed has nudged the PDO damping outbreaks over the past few weeks.

The GFS, GEM ensemble suggest the coldest air late next week will be from Louisiana to the Carolinas. We'll see.

It's ain't over yet - but enjoy mild weather for the next week. It's not like there's a shortage of warm weather in SE Texas, though!

Winter, what winter?
We've had maybe two somewhat cold snaps lasting two or three days.
Now the winter of 2013/2014.....that was a winter.
Believe me I don't mind, but this winter is laughable.

Its Ground Hog Day 2017. According to folklore Spring will arrive early if the ground hog does not see its shadow this morning. A cold front is moving across SE TX this morning with clouds and a few light showers thus perhaps no shadow for the ground hog this morning. Temps forecast rise into the mid to upper 70s early next week.

Cloudy skies, slightly cooler temps Friday and Saturday, and 20-30% of showers through the Houston Superbowl weekend.

Phil saw his shadow - so six more weeks of winter.

Hence the quotation marks around "winter."

I thought 2015 was colder than 2014, at least in CLL...will need to check


Yes - on average, 2015 was colder for us. 2014 had a brief cold snap in early March, but February in 2015 was considerably colder that 2014 and persistently so.


I need to mentioned that the temp discrepancy between CLL and HOU has been greater than normal this "winter." We were on the colder side of the battle of the air masses for over a week.

Cooler should transition to increased clouds and warming temperatures Saturday night into Super Bowl Sunday as a retreating frontal boundary and a foggy start of the day gives way to some breaks in the clouds and a slight chance of a light shower or two during the Super Bowl festivities.

Saturday afternoon briefing from Jeff:

Light rain, drizzle, and fog will be developing late this afternoon into the overnight hours as a warm front moves northward across the region.

Already seeing the cloud deck lowering as increasing warm air advection overrides the cooler easterly flow at the surface. Warm front located offshore will begin to move inland this evening while coastal trough currently producing light rain over S TX shifts NNW. Expect periods of light rain and drizzle to develop around Matagorda Bay and move NE across SE TX tonight while the cloud deck lowers as the warm front approaches from the SSW. Think fog will also likely begin to develop after midnight and last well into Sunday morning before the warm front sweeps north helping to scour out the low level fog and low clouds. GFS hinting at better rain chances Sunday morning (near 50%), but other models are drier and think much of what the GFS is suggesting will be drizzle and light rain even though that model wants to produce some thunder. Warm front should cross metro Houston mid to late morning with improving visibilities and lifting decks. Isolated showers may continue to stream inland from the Gulf, but latest high res guidance suggests most activity will end with the warm frontal passage.

Next item of concern will be dense sea fog advection from Galveston Bay into Galveston/SE Harris County Sunday evening. Wind profiles (ESE/SE) over a long fetch of cool shelf waters seems to support a decent threat of dense sea fog after 900pm Sunday into Monday.

Aviation:
4,100 arrivals and departures out of IAH and HOU this weekend along with numerous aircraft in the air on Sunday.

Flying conditions will be messy especially this evening into midday Sunday and then again Sunday night. Mid level deck is already lowering and expect this to continue this afternoon with fog and patchy light drizzle/rain developing. CIGS dropping to around 1000 ft this evening then down to 500ft overnight into Sun AM especially at HOU. Winds will veer from E to SE then S early Sunday with warm frontal passage. Will see slow lifting Sunday AM until warm front passes then rapid improvement in CIGS and VIS. Sunday afternoon into early evening should be decent with mixed boundary layer helping keep CIGS elevated. Doubt HOU/IAH will see much better than 5-7 mile VIS given onshore flow south of the warm front and typical hazy/foggy conditions with inland advecting marine layer.

Sunday evening sea fog will crater CIGS and VIS rapidly from the coast working inland. Could see sea fog into SE Harris County as early as 800-900pm Sunday, but much more likely around midnight with impacts at HOU between 1000pm to 100am. VIS rapidly falling to less than 1 mile is possible with rapid decline in CIGS from 2000-1500ft to less than 500ft over a few hours or less. Likely very slow recovery on Monday AM.

No wind issues except veering direction (E to S) at less than 10kts for the next 36 hours.
