February 2016: Quiet Warm Weather To End The Month
It is way too hot for this time of year. I sweated like crazy doing light yard work the last two days.

The 0z and 6z GFS operational runs have backed off on the winter storm scenario for the Feb 9-11 period. However, the 0z Euro operational run lays down a swath of 1-2" of snow across much of south central Texas in that period. The CMC remains bullish as well. The signals are clearly there for a storm system to impact the state in that time frame. As always the big questions will be how cold is the airmass and how much moisture will be in play.

The immediate concern will be the rather High Impact Spring like storm existing the Southern Rockies tomorrow into Tuesday and the Severe Weather potential for our neighbors to the North and East.

That is true, srainhoutx. There is also a fire weather danger today in west Texas and stretching into parts of central Texas by Tuesday. It's hard to believe it's there after having the state's wettest year on record ... but NWS offices are expressing concern due to high winds, low humidity, and dead vegetation as a result of it being "winter."

The 12Z Euro and Canadian models are completely opposite of the 12Z GFS. The Euro particularly raises an eyebrow when looking ahead to next weekend. We know that a strong Canadian front will sweep across the Lone Star State on Tuesday with much chillier temperatures late next week. The Euro suggests two cold upper air disturbances passing over our Region after the cold air is in place. Typically in early February IF we can get a shortwave or two passing over cold air at the surface, interesting things can develop. Looks like a long week of watching the various computer schemes to see if this is a mirage or a real potential.

Hit 86 degrees here in Austin at Camp Mabry (KATT) at 3:15 pm, easily shattering the record high for this date of 83 set in 1911. It was probably helped by the West Texas dry line which slipped into town and kinda bisected the metro area with the temp rising 4 degrees and dew point dropping 14 degrees in one hour. Interesting to see we had a 41 degree dew point at KATT while the airport, just miles away, had 53 degree dew point at same time.

The overnight guidance continues to advertise a full latitude trough digging well South across North America. The guidance also suggests a Stratospheric Warming event across the Polar Region of the Northern Hemisphere with a strong blocking signature. The blocking signature is indicated by the orange 'U' shaped area from the West Coast to Greenland. The blue shades are indicative of full latitude trough with temperatures departures nearing the -20 degree range. There are growing indications that some areas may near 2 Standard Deviation below normal, temperature wise. Will this pattern translate to much colder for our Region? It's a bit too soon to know.

Morning briefing from Jeff:
Record to near record warmth continues today…but colder air will return late Tuesday.
Southerly flow has greatly moistened the low levels of the atmosphere with dewpoints running 60-65 degrees over much of the area. Light winds overnight and this morning with high dewpoints over chilled near shore waters is resulting in a sea fog bank along the upper and mid TX coast. Visibilities have been bouncing all around this morning along the coast between nearly 0 to over 2 miles at times as the sea fog bank sporadically moves inland. Fog has generally lifted into a stratus bank inland with a slightly stronger breeze. No real change until early Tuesday along the coast so expect the fog bank to be maintained and varying visibilities at times.
Think some areas with enough sun will have no problem reaching 80 today and areas across S and SW TX will likely rise into the 90’s.
Upper level storm system heading for the Midwest today and Tuesday will drive a pre frontal trough across the area early Tuesday followed by a strong frontal passage late Tuesday. Pre-frontal trough may be able to squeeze out a shower or two over the region, but moist surface air mass is generally shallow with very dry air mass above…a function of the air mass since late December. Will go with a generous 30% rain chance…but not expecting much.
Dry WNW winds will lower dewpoints and RH values on Tuesday. Have had a bit of fire behavior over the weekend with dead/frozen winter fuels, but think conditions on Tuesday will not support a critical fire weather concern. Conditions will be elevated however especially west of I-45.
Strong cold front will progress across the area late Tuesday afternoon with strong cold air advection driving temperatures into the 30’s by Wednesday morning. Cold high pressure will build down the plains and into TX with cold nights and cool days Wednesday-Friday. Low temperatures Thursday and again on Friday morning may touch freezing in the normally colder locations and away from urban areas. Overall clear skies and little chance of rain beyond Tuesday.
Next weather system will approach the area on Saturday with increasing clouds over the cold surface dome. Moisture once again looks meager, but strong lift will work with what moisture is available to produce at least a chance of showers over mainly the southern half of the region Saturday. If more moisture than currently expected is available…this system could be fairly wet. However pattern of late has been to take the drier solutions…somewhat unusual for TX El Nino winters.
Next Week:
Some of the longer range forecast models…ECMWF and CMC…have been indicating the development and southward progression of an arctic air mass toward the start of next week. Model solutions this winter have been far less than stellar with both cold air intrusions and potential storm systems at the longer range which leaves little confidence in what may transpire next week. While we have experienced a very nice warming trend these last few days…winter is not over.

Warm this puppy up. Can't wait for spring. Winter can go jump in a wood chipper.
Promises. Promises.
Drier and warmer have been the norm. Although Jan was slightly cooler than average in CLL, not much wintry excitement.
Bastardi was right about the East Coast Blizznado...we'll see if he's right on the cold...fingers crossed for disturbances sliding across with good timing.

Who has said anything about promises, DoctorMu? Srainhoutx was merely stating what Jeff said what could be taking place in this vicinity of the country weatherwise if and when all of the elements come together starting tomorrow & feasibly lasing into this weekend if everything pans out the way the Euro computer models are showing. Hi, I sleetstorm have returned. I am a high-functioning autistic person, only so you know.
Groundhog did not see his shadow. Early Spring....There, I said it....lol

Ha, no news there....biggest dud of a winter in recent memory
Where is the "LIKE" button....no lie!!BiggieSmalls wrote:Ha, no news there....biggest dud of a winter in recent memory
70°F, sunshine, and a DP of 24°/18% RH in CLL
Could not be a better day.
Bottle this for the summer!
Cool and dry for the remainder of the week with a slight chance of rain Friday night as the Southern Jet twerks with the polar jet. Light freezes possible the next 2 nights in CLL to NW Harris Co and our heat sink in Conroe.
Maybe a strong cold front next Tue with an active Jet. Hope a disturbance actually fills the hose with well-timed (frozen) precip. There's not much of a chance, but it may be best we have for any mischief.
