544 AM EST Fri Jan 26 2018 Warmer air will continue to flow into the region into this weekend with highs reaching the mid 40s to the mid 50s today and Saturday.
An approaching Polar trough will pull plenty of Gulf moisture into South TX to generate good chances for rain Today into Saturday. A cold front moving through the area during the day Saturday looks perhaps the best opportunity for isolated brief thunderstorms to form over the area.
A weak cold front will move south across the terminals tonight and early Saturday.
A period of snow will occur across northern Nevada Saturday into Saturday night as warmer air attempts to push back into the state.
422 AM CST Fri Jan 26 2018 Weak ridging lingers over SETX this morning with coastal troughing along the mid and lower coast. Today should be a few degrees warmer than yesterday with mostly cloudy to cloudy skies. Deep convection will probably be confined to areas to the south of the Highway 59 corridor and primarily focused over the coastal waters. As the s/w departs the eastern areas a lull will probably develop Saturday morning with the cold front entering the picture and pushing through to the coast Saturday mid to late afternoon.
Broad cyclonic mid level flow in wake of yesterday's shrtwv trof will favor the development of a low level thermal ridge and thus warmer temps, mostly M60s-L70s. As a trough moves east thru the central plains Fri evening an assocd cold front will move s and is expected to be just s of I-20 by 3 AM Sat.
938 AM EST Fri Jan 26 2018 High pressure heads east today, with southwest flow ushering in milder air to start the weekend. A cold front crosses Saturday/Saturday night.
A few showers will be possible today but will gradually fizzle out as a brief period of high pressure passes through the region.
High pressure will build off the southwestern Pacific Coast through the remainder of the weekend causing flow to become more northwesterly with time as the feature amplifies up into the Northwest Territories of Canada.
408 AM PST Fri Jan 26 2018 Precipitation chances will retreat northward over the next several days as ridging over the eastern Pacific moves over NorCal.
Generally 2-4 inches can be expected across the higher terrain of the central mountains with maybe an inch or 2 over the ranges farther south. Otherwise, the main impact from this system will be the wind and the high fire danger it will create. Gusts won't be what they are in the mountains right now but gusts over 30 to 40 mph will possible down to the lower elevations.
527 AM EST Fri Jan 26 2018 High pressure should maintain dry weather until rain chances return with a Saturday cold front. Sunny and dry weather is expected today as ridging builds across the area. Clouds should increase late tonight ahead of an approaching upper trough and associated sfc cold front.
Cool overnight temperatures expected the next two nights with overnight lows near freezing in coldest valleys. Current temperature readings are ranging from the upper 30s to upper 40s, cooler than yesterday at this time by a few degrees. A high pressure ridge is progged to build in over the Eastern Pacific beginning today, and gradually edge in over California over the next day or two.
458 AM CST Fri Jan 26 2018 Another mild and breezy day is on tap with the area between high and low pressure to our east and west, allowing for continued southerly flow. A cold front will push toward the area tonight, with increasing moisture ahead of it.
Daytime heating should be sufficient to add another 10-15 degrees with readings approaching 60 in the south to the lower 40s over the snowpack in the northwest.
Latest surface analysis showing a cold front pushing through southeast Wyoming at this time. May need to cancel the High Wind Warning early up there as strongest winds look to be between now and 12Z.
1054 AM EST Fri Jan 26 2018 Strong high pressure centered over the mid-Atlantic coast will slowly drift east. Partly cloudy skies will prevail with near average temps inland and a little below average along the coast due to the cooler onshore flow.
Current observations are reporting some light snow with this, but forecast soundings continue to indicate a loss of ice later on, so will keep the mention of freezing drizzle in the forecast. Cold front continues to gradually work its way into western North Dakota. Upper level analysis places trough stretching from the lee of the Canadian Rockies into central Montana. cold front will continue its march across the area with increasing northwest winds. Forecast soundings indicate that this may be a mix of some light freezing rain or snow, but chances for development remain on the lower side as main area of precipitation is expected to remain to the north. Notably cooler temperatures expected, with highs returning to below average.
435 AM CST Fri Jan 26 2018 (Today and Tonight) An upper trough currently over the Rockies will move east across the central and northern Plains later this afternoon. An associated cold front will move south across the area tonight, with the front clearing far southern counties around sunrise Saturday morning. Could see a few warm advection showers over far southeast counties mainly this morning but a better chance for scattered showers will be later tonight in advance of the cold front.
Temperatures trend cooler today with brisk west winds. A cold front will back into north-central Montana late tonight, lowering temperatures into the teens and 20s on Saturday.
946 AM CST Fri Jan 26 2018 Adjusted our mention of fog as the lowest visibilities have moved east into the Red River Valley. Main concern will be p-type (potentially freezing drizzle) with any light precipitation that occurs this afternoon/evening. Guidance does not indicate precipitation this morning (forcing is very weak), but as winds become light fog (maybe freezing fog?) could be an impact through the morning hours. Forecast soundings show the potential for freezing drizzle (no ice crystals in cloud) initially, transitioning to snow. With that said, potential for freezing drizzle/snow enough to message.
Highs will range from the mid-upper 60s north of Orlando to the lower 70s across srn sections. Strong high pressure along the Atlc seaboard will push eastward into the western Atlc thru the next 24 hours.
/NF/ Today and Tonight: Today should be a few degrees warmer with humidity levels noticeably higher thanks to continued southeast winds across the region.
Gusty southerly winds will also develop this morning and continue into this evening ahead of a cold front approaching the CWA. This evening and overnight the cold front is forecast to move through the CWA with MVFR ceilings and possible rain showers ahead of the front. Otherwise, mild and windy conditions expected today ahead of upper trough moving into the central Rockies. As upper trough swings into the Central Plains tonight, areas of light rain/drizzle will be possible across northeast Oklahoma ahead of approaching front with precipitation coverage increasing as boundary moves into southeast Oklahoma/northwest Arkansas late tonight. Temperatures will not be significantly colder behind front on Saturday with mostly sunny skies and highs back into the lower 60s across much of eastern Oklahoma and west-central Arkansas.
617 AM EST Fri Jan 26 2018 High pressure along the Eastern Seaboard moves out to sea tonight and Saturday.
341 AM MST Fri Jan 26 2018 The cold front has pushed into the central mountains early this morning and is draped back across the lower Gunny River back into eastern Utah. Much cooler temperatures will move in behind this front and will be most noticeable in the high country. We remain in the northwest flow with moisture topping the ridge to the west and brushing our northern mountains again on Saturday later in the day. Northwest flow aloft and a large ridge over the Great Basin to the west coast will bring dry weather to most of eastern UT and western CO, except over the northern mountains of CO.
A trough was over the western U. with moisture streaming in ahead of the trough and spilling over the ridge over the upper Mississippi Valley. The trailing longwave trough moves through the Plains through tonight. This will trough will gradually usher in a cold front through the day. High clouds should increase this morning with the jet level support and mid clouds should increase this afternoon ahead of the longwave trough.
This weekend a warm front accompanied by a moderate atmospheric river moves across the region.
The local Doppler radar remains free of precipitation and temperatures so far have reached the low 70s.
A cold front is expected to move across the region beyond the end of the current TAF period. /ISSUED 422 AM CST Fri Jan 26 2018/ Weak ridging lingers over SETX this morning with coastal troughing along the mid and lower coast. Today should be a few degrees warmer than yesterday with mostly cloudy to cloudy skies. Deep convection will probably be confined to areas to the south of the Highway 59 corridor and primarily focused over the coastal waters. As the s/w departs the eastern areas a lull will probably develop Saturday morning with the cold front entering the picture and pushing through to the coast Saturday mid to late afternoon.
511 AM CST Fri Jan 26 2018 A generally milder day is in store as a surface/upper level trough slides across the region. With the passage of today's trough, Saturday will have slightly cooler temperatures with highs mid 30s to near 40. A cold front drops southward during the day, bringing in much colder air for Saturday night with lows just either side of 10 degrees.
641 AM EST Fri Jan 26 2018 High pressure centered over the area this morning will slide offshore this afternoon into tonight and Saturday.
Models indicate the trough will be to the east of the area by mid-afternoon and have decreased cloud cover during this timeframe. At the surface, high pressure is located along the Atlantic Coastline. Despite the upper level trough, 500mb heights are elevated and highs will top out 5-10 degrees above normal.

540 AM EST Fri Jan 26 2018 High pressure should maintain dry weather until rain chances return with a Saturday cold front. Sunny and dry weather is expected today as ridging builds across the area. Clouds should increase late tonight ahead of an approaching upper trough and associated sfc cold front.
956 AM EST Fri Jan 26 2018 High pressure will crest over the region today. A cold front will approach tomorrow and cross the region Saturday night. Temps shud warm a couple degrees more than yda and with winds expected to lighten throughout the day it wl feel warmer. A high pressure SW of the coastal waters will be ridged into Maine. A cold front moving east the associated low over James Bay, the cold front extending south through the eastern Great Lakes. By early afternoon Saturday the cold front will move into western Maine.
Cold front has exited the southeast tip of the forecast area early this morning, with the rain recently ending at Lawrenceville. While the southwest half of the forecast area may eke out some lower 40s this afternoon, temperatures will fall well below freezing tonight.
On the hemispheric scale, ridging along the West Coast and deep troughing across the eastern half of North America will continue. The next coherent cold front looks to be Wednesday Night, as the global models agree 850mb temperatures in the -8 to -11C range will push into Kansas, but mainly the central part of the state.
933 AM PST Tue Dec 5 2017 Strong high pressure will intensify over the Pacific Northwest early this week, persisting through at least the weekend. Areas of low clouds and fog will develop in the lowlands by midweek, persisting through at least the weekend. Today and Wednesday: The main forecast challenge for the next several days will be the potential for fog and low clouds under an increasingly strong high pressure ridge.
228 PM CST Tue Dec 5 2017 The short term concern is cloud/flurry trend into the evening and then timing of the next short wave trough dropping south over the area Wednesday. Clouds and flurries remain over the eastern cwa this afternoon as the cold trough exits to the east. Will develop some lower end PoPs to the northeast and spread those west and south into Wednesday as the next trough moves south. The longer term trends remain on the cool side with the north/northwest flow continuing with the eastern CONUS trough in control. Periodic cold fronts will drop south in the flow pattern every 24 hours or so with small end chances for some light snow/flurries.
/issued 537 AM CST Tue Dec 5 2017/ A potential winter storm is heading toward west Texas and Much cooler temperatures are expected today across the entire forecast area as an upper level trough across the Mississippi valley sends a strong cold front towards the Mexican border this morning. A high probability of a mixture of snow, sleet, rain, and freezing rain is expected to rapidly develop late tonight across much of the region. Forecast soundings indicate that freezing rain will be the more dominant precipitation type later tonight across the mountains. The mixed precipitation will be more confined to the Big Bend Wednesday night where warmer air aloft and at the surface will linger.
/issued 327 AM CST Tue Dec 5 2017/ Cold front currently along a line from Rusk, Texas, to El Dorado, Arkansas. Pressure gradient to relax overnight as high pressure settles across the region.
Main theme for the next couple of days will be for the upper energy over the northern Rockies to quickly dive southeast and further enhance the upper trough from eastern Quebec into the central Rockies. As this trough continues to dig, an additional surge of cold air will spill south Wed evening into Thu morning. By Fri afternoon, upper trough axis will extend from the eastern Great Lakes into southern TX with strong northerly flow over the Plains. For the weekend, upper trough will continue to migrate east with northwest flow remaining over the Plains.
224 PM CST Tue Dec 5 2017 Upper level positively tilted trough that lies from southern California into northwest Oklahoma is expected to continue to move southward away from the Panhandles overnight. The precip associated with this trough will likely stay to the south of our area. The upper level pattern will be dominated by a trough over the eastern U. and a ridge over the West Coast of the United States.
334 PM CST Tue Dec 5 2017 Tonight through Wednesday: The cold front currently extends across the southeastern portions of the ArkLaMiss this afternoon, and will continue to move southeast out of the area.
Cold front is pushing south and is about to enter the northern CWA. Strong cold front will sweep south across area waters this afternoon with strong north flow developing in its wake.
358 PM EST Tue Dec 5 2017 An area of high pressure will continue to bring mainly dry weather to the region for tonight. On Wednesday the pattern will begin to shift as the winds begin to veer to the southeast and then the south southeast as a cold front approaches from the north.
/issued 355 AM CST Tue Dec 5 2017/ A strong cold front is knocking on the door at 09Z. Once the cold front clear the area cold air settles in and several upper level impulses /clipper systems/ move through the southeast.
250 PM EST Tue Dec 5 2017 A strong cold front moving into the forecast area late tonight will reach the coast Wednesday.
1247 PM EST Tue Dec 5 2017 Showers will move across the area this morning as a cold front traverses through the Ohio Valley.
350 PM CST Tue Dec 5 2017 Additional light snowfall is expected this evening and overnight for much of the area as a weak vorticity maximum rotates around the large upper-level trough centered over the Great Lakes and eastern U. Wednesday will be another breezy and cool day, with temperatures a few degrees cooler than Tuesday. The overall weather pattern will change little over the next 7 days, with a massive upper level trough over the eastern CONUS and an amplified ridge over the West Coast.
312 PM EST Tue Dec 5 2017 A cold front continues to move southeast across the area. Once the front passes colder air will push into the area and weak surface ridging will build into the area from the southwest.
1153 AM CST Tue Dec 5 2017 Brisk weather and much cooler temperatures have settled into the area. An upper-level ridge extended along the eastern US coast into New England, with another off the northern Pacific coast. Cold air had plunged into the central US, with an 850mb low centered in northern MN/western ON and 850mb cold front extending from near the WI-MN border through eastern IA/northwest MO/southeast KS. Behind the low and front, 850mb temperatures were in the teens below 0C from northern NE through the Dakotas. The low- to mid-level baroclinic zone should linger across the area on Wednesday, with reinforcing cold air pushing the boundary southward on Wednesday night.
244 PM EST Tue Dec 5 2017 A cold front will push east through the region overnight and will be followed by a shallow ridge of high pressure on Wednesday.
313 PM EST Tue Dec 5 2017 A sharp cold front will arrive early Wednesday bringing rainfall and plummeting afternoon temperatures.
1116 AM MST Tue Dec 5 2017 Extended the High Wind Warning until 2 pm this afternoon for Arlington and added Bordeaux based on their recent wind speeds. Clear to partly cloudy skies over the CWA with an upper trough axis moving east of the area.
Weak high pressure will continue to settle in across our terminals for tonight, keeping surface winds light and variable, with a return of northerly surface winds after 12Z.
257 PM CST Tue Dec 5 2017 Cold air advection continuing across the region this afternoon following yesterday's cold frontal passage. The bigger story will arrive Wednesday night when a secondary shot of cold air surges south over the lower Missouri Valley following the passage of a reinforcing cold front.
231 PM EST Tue Dec 5 2017 Cold front exits early tonight.
1200 PM CST Tue Dec 5 2017 Strong low pressure over south central Canada will drift northeast over the next 24 hours while the pattern aloft begins transitioning to a high amplitude ridge over the western U. and full longwave trof over the east.
1107 AM EST Tue Dec 5 2017 Rain is expected today with a crossing cold front. Showers will continue until the passage of the cold front this afternoon/evening. Variably cloudy conditions are expected through the rest of the period in cold advection and broad upper troughing.
226 PM MST Tue Dec 5 2017 Broad upper trough is persisting across the eastern half of the CONUS while upper ridging/Rex blocking pattern has set up over the western CONUS and Pacific Coast. Next upper wave near the MT/Canadian border will swing through late tonight bringing a reinforcing cold front to the area. A slight eastward shift of the upper ridge will bring warmer temperatures to the region with highs reaching into the 50s by the end of the week.
358 PM CST Tue Dec 5 2017 The upper air pattern continues to transition such that a deep trough will be located over the eastern CONUS. The first of several embedded disturbances will rotate across the area tonight within the developing longwave trough over the eastern half of the CONUS.
331 PM EST Tue Dec 5 2017 Rain will taper off with the departure of the cold front. Showers will continue until the passage of the cold front this evening.
Winds will become light and variable tonight then modestly increase Wednesday morning with secondary push of cooler/drier air.
The coldest air so far this season settling over the region will lead to freezing low temperatures across much of the region through Wednesday morning. Temperatures will slowly recover late this week with winds gradually decreasing except for the lower Colorado River Valley where breezy to windy conditions will persist into the weekend.
1255 PM EST Tue Dec 5 2017 Aviation A strong cold front will push east of the region today.
/issued 624 AM CST Tue Dec 5 2017/ Stg cold front movg across southern portions of the cwa with a line of showers with moderate to heavy rainfall along the front, and a few heavy showers south of front. /issued 327 AM CST Tue Dec 5 2017/ Cold front currently along a line from Rusk, Texas, to El Dorado, Arkansas. Pressure gradient to relax overnight as high pressure settles across the region.
258 PM EST Tue Dec 5 2017 Cold front and associated band of shallow convection is a bit slow advancing across north Georgia this afternoon. Would not expect any significant accumulations, however the higher elevations of the north Georgia mountains may see a little.
A strong cold front moving into the forecast area late tonight will reach the coast Wednesday.
1242 PM MST Tue Dec 5 2017 A very large high pressure ridge along the west coast extending north well above the Arctic Circle will produce cool dry northerly flow over western and central Wyoming through the week with gradual warming.
Under mostly sunny skies with a slowly moderating east to southeast breeze, temperatures along the Keys island chain have climbed into the lower 80s. The local area will remain on the southern periphery of a broad but slowly weakening area of high pressure draped across north central Florida over the next day or so.
Morning Boise sounding trace showing surface based inversion and building inversion aloft as the upper ridge builds along the West coast. Fog/stratus formation again Wednesday morning in the lower valleys. The much talked about ridge is building closer to the coast this morning. Northwest flow aloft will veer to northerly by Wed as the high-amplitude ridge becomes aligned just offshore. We have continued the trend of cooling the valleys and warming the higher elevations in the short term. We expect the inversion to show itself first in the Lower Treasure Valley and Upper Weiser River Basin, along with all the mountain-valleys. There is no way to know for sure when low clouds or fog will begin, so we have continued the ongoing forecast of hinting at it mainly in the Lower Treasure Valley Wed.
Cold front is currently progressing Swrd across S TX as of writing with MVFR CIGs (Cu/Tcu) to the S of the front and MVFR CIGs (stratus and stratocu) to the N of the front.
A cold front is pressing slowly east across Middle Tennessee at mid afternoon. The upper trough driving this system is rather unimpressive for the active colder season. There will just be a slight chance for a sprinkle or flurry in the higher terrain along the North Carolina border through the remainder of the overnight period, as cold air builds into the region.
1225 PM PST Tue Dec 5 2017 Strong high pressure will intensify over the Pacific Northwest early this week, persisting through at least the weekend. Areas of low clouds and fog will develop in the lowlands by midweek, persisting through at least the weekend. 18Z TAFS: A high pressure ridge will continue to build in over the region.
Cold front currently extends from columbus to just north of Jackson to Vicksburg this morning and is moving to the southeast. /15/ Prior discussion below: Today and Tonight: As of early this morning, the much anticipated cold front is knocking on our door. An area of light showers was lifting northeast across the forecast area ahead of this cold front. Light rain will continue to be possible for a few hours after the frontal passage, however rain chances will diminish by this evening as drier air starts to work its way into the lower levels. A slight chance for light rain will return to mainly southern parts of the area by daybreak, as frontogenetic forcing associated with the elevated cold front causes moist, isentropic lift over the cooler surface airmass.
