439 AM MST Wed Nov 22 2017 Water vapor shows highly amplified upper ridge over the western CONUS, with ridge topping wave over southern Canada pushing into the Northern Plains. At the surface, lee trof is advancing into eastern MT/WY. Thermal profiles along with downslope flow will push temps well into the 60s today, slightly cooler in the Hills. On Thanksgiving, upper ridge axis will move into the Northern Plains with even warmer temps expected, 70s on the SD plains.
421 AM CST Wed Nov 22 2017 The upper level ridge that has taken up residence over SOCAL will continue to dominate our weather over the holiday weekend.
640 AM EST Wed Nov 22 2017 An area of low pressure will shift NE offshore the NC coast today, with light rain exiting our forecast area early this morning.
Surface observations this morning show a cold front is moving through the Mid State with temperatures in the 30s to low 40s and north to northwest winds.
A southwesterly flow aloft will dominate the short term forecast as a ridge continues to build over southern California. Precipitation continues to spread across the region under a moist southwesterly flow aloft associated with a deep, subtropical moisture tap; rain showers will persist north of a Burns-Boise- Featherville line through late morning, finally shrinking north this afternoon as the ridge builds over the region. This will temporarily suppress the ridge, allowing for showers to spread across the east-central Oregon and west-central Idaho mountains once again Thursday afternoon.
957 AM EST Wed Nov 22 2017 A weak area of low pressure off the NC coast this morning will accelerate northeastward off the Mid-Atlantic today. Meanwhile, a cold front will move through the area later this morning.
An area of low pressure, currently over Alberta will track southeastward across the region today. Warmer temperatures will move into the region today with highs ranging from the mid 30s, in western MN, to the upper 50s and low 60s, west of the Missouri Valley. An upper level ridge, along with southwesterly winds will usher in much above warmer temperatures into the region on Thursday.
low pressure continues to move out of the Gulf of Mexico and cross the Florida peninsula.
Some higher elevations in the west were much warmer and windier than lower elevations further east. TFJ Warm front moving slowly from central Montana early this morning. This will limit the strongest winds to the higher terrain areas around the Little Rockies and Big Sheeps. The front will linger over the region overnight, and with high pressure sliding from Saskatchewan into North Dakota, could see a slight push of cold air under the incoming warm airmass.
A ridge of high pressure will shift ewd across srn WI today, with swly winds and weak warm advection beginning in the afternoon. Full sunshine and the weak WAA should be able to boost temps into the lower to middle 30s, before the high clouds arrive for late afternoon. Forecast soundings show the low levels of the atmosphere remaining fairly dry in srn WI, with better chances of saturation to the north.
High pressure will bring another warm day to the area today. Rain chances return to the North Bay on Thanksgiving, but the rest of the region is expected to remain dry with slightly cooler temperatures.
Breezy conditions were accompanying the cold front passing through the region early this morning. The colder airmass ushered in by the overnight cold front passage will pull high temps back into the low to mid 40s today.
For today the area will be in between systems with not much of any forcing, but daytime heating combined with the low level moisture and a weak sea breeze could pop a couple of showers and possibly a thunderstorm over inland areas. Winds will begin to increase tonight into Thursday as low pressure develops over the central Gulf of Mexico.
424 AM PST Wed Nov 22 2017 High pressure aloft near the West Coast combined with weak offshore lower level flow will bring record setting heat through Thanksgiving.
723 AM EST Wed Nov 22 2017 A cold front will move west to east across the North Country today, bringing rain and snow showers to the region.
The low point, as far as temperatures go, will come this morning as high pressure moving into the area allows for good radiational cooling. High pressure will remain over the area which will allow for copious sunshine however mixing will be weak so temperatures will remain below normal with highs in the low to mid 40s. A brief period of warm air advection will get underway tonight as high pressure shifts eastward however, another area of high pressure will move back into the area for the Thanksgiving holiday.
537 AM CST Wed Nov 22 2017 Surface map early this Wednesday morning has high pressure centered over eastern KS/NE with ridge extending northward into the Upper Mississippi River Valley Region. The area/ridge of high pressure will drift southeast of the region today as a wave of low pressure drops southeast out of Alberta into the Northern Plains. The wave of low pressure moves southeast through the area tonight, spreading the likelihood of some light snow across north central WI, including Clark Taylor counties. Thanksgiving Day looks fantastic as a weak ridge of high pressure drifts across the region.
Satellite images show an amplified ridge extending from the Baja coast north over the west coast. The strong ridge of high pressure will provide very warm conditions across the central California interior.
302 AM MST Wed Nov 22 2017 An upper ridge over the western states and an upper trough from the Great Lakes to the Gulf of Mexico will keep Colorado under north-northwesterly flow. Some moisture in the flow will continue to bring light orographic snow to the high country today, with accumulations less than an inch. Northwesterly winds of 30-45 mph in the high country will become a little more widespread. With the warm advection in place, some high clouds remaining overnight and a slight gusty downslope wind pattern overnight, minimum temperatures will likely be above freezing across the plains. The high pressure center over the Pacific will deepen slightly and continue to bring strong NW flow over the region. This will aid in the slight increase of temperatures over the Metro bringing highs into the low 70s.
By early to mid afternoon, the wind will return to a southerly direction across west central and northwest Oklahoma where somewhat warmer temperatures are expected.
/issued 415 AM CST Wed Nov 22 2017/ Cold front continues its southward push toward the Gulf coast this morning with just some lingering stratocu cloud decks over parts of east Texas extending down across Toledo Bend country into west central Louisiana. High temperatures will only manage to warm into the mid and upper 50s to lower 60s this afternoon followed by rapid cooling overnight as lows bottom out either side of freezing to begin Thanksgiving Day, setting the stage for a nice warm-up back near 60 degrees north to lower and mid 60s south with ample sunshine.
404 AM CST Wed Nov 22 2017 An area of low pressure, currently over Alberta will track southeastward across the region today. Warmer temperatures will move into the region today with highs ranging from the mid 30s, in western MN, to the upper 50s and low 60s, west of the Missouri Valley. An upper level ridge, along with southwesterly winds will usher in much above warmer temperatures into the region on Thursday.
1032 AM EST Wed Nov 22 2017 High pressure will gradually build across the area today.
High pressure will move over the state by this evening. Today Through Thursday Night The cold front has pushed south through the state as of early this morning. This drier air will continue to filter into the state this Wed as high pressure to the north moves south into the region.
523 AM CST Wed Nov 22 2017 The region remains in between amplified ridging over the western states and a trough over the eastern third of the country.
/issued 357 AM CST Wed Nov 22 2017/ A cold front bisects the area this morning although the boundary appears to have taken on a very wavy shape as analyzed based on dewpoints. Scattered light to moderate showers continue along the coast becoming more numerous offshore as the upper trough axis extends nearly halfway across the gulf of Mexico. As the trough continues its southeasterly progression, skies are expected to clear by mid to late morning yielding sunny and cool conditions by this afternoon. The pressure gradient in the wake of the front will result in breezy conditions area wide today with winds diminishing overnight as high pressure builds across the region. With high pressure in control, the cool, dry weather will continue through the weekend.
Temperatures are going to be similar today as yesterday with 850 mb temperatures 3 degrees warmer than yesterday at this time. In Roseburg winds have already mixed down with the current record temperature already at 68, and have bumped up the high there to a new record of 71 since there will not be influx of warmer air there, and with the overcast deck with showers already in that area there should be only marginal additional temperature rise. With the upper level ridge shifting east of the region Thursday this front will bring precip over to the east side Thursday afternoon.
A much cooler day will be in store today as the region continues to feel the effects of yesterday's cold front passage. Also as a result, a very good radiational cooling set up will be in store overnight tonight allowing temperatures to efficiently drop into the 30s across the CWA, with some locations seeing at or below freezing, mainly in the low lying areas of the Hill Country. With building heights and high pressure continued at the surface, a chilly morning will quickly improve to highs in the low to mid 70s with light wind and clear skies.
Dry and Much Cooler. With dry cool air in place over the region, temperatures today and tonight will be cooler than seasonal normals. Lows tonight mainly in the 35 to 40 range will dominate; however, some low-lying areas may have lows closer to freezing.
Areas that we are concerned with experiencing strong winds include the Flathead Valley south to Missoula, through the Bitterroot Valley, and the valleys of southwestern Montana, so the High Wind Watch has not been changed. One aspect of this Thursday weather pattern that is interesting is that the upper jet will be parallel to the cold front which is usually a good set up for precipitation, so moderate to even heavy rain may accompany the strong winds. Snow levels will lower behind the cold front Thursday night so snow is likely to return to the high terrain and there may even be some snow at lower elevations.
948 AM EST Wed Nov 22 2017 A cold front will move west to east across the North Country today, bringing rain and snow showers to the region.
930 AM CST Wed Nov 22 2017 Northerly flow persists behind a surface cold front that moved through the TN Valley early this morning. Winds will increase just a bit over the next couple of hours, as the pressure gradient increases in response to high pressure building into the region. Despite the clear skies, strong cold air advection will prevent much of a warm up today as highs struggle to make it out of the lower 50s.
Surface analysis from this morning shows that the dry cold front has shifted through the S. With strong ridging re-establishing along with a strong low to mid level subsidence inversion over the area, rain chances will be at 0 percent.
641 AM EST Wed Nov 22 2017 A cold front exits east first thing this morning.
717 AM EST Wed Nov 22 2017 A cold front will push southeast across the region early this morning. High pressure will then build into the area for the second half of the week.
415 AM CST Wed Nov 22 2017 Cold front continues its southward push toward the Gulf coast this morning with just some lingering stratocu cloud decks over parts of east Texas extending down across Toledo Bend country into west central Louisiana. High temperatures will only manage the mid and upper 50s to lower 60s this afternoon followed by rapid cooling overnight as lows bottom out either side of freezing to begin Thanksgiving Day, setting the stage for a nice warm-up back near 60 degrees north to lower and mid 60s south with ample sunshine.
North winds have developed in the wake of a cold front early this morning. MVFR cigs linger over KCRP early this morning, but should clear within the next few hours as drier air continues to push into the region in the wake of the cold front. A cold front has been moving through the region early this morning. Low pressure over the Gulf of Mexico will shift further east this afternoon as high pressure settles further south into South Texas. Anticipate lows to fall to the upper 30s across the Victoria Crossroads/northern Brush Country, and into the low to mid 40s further south.
With the storm track north of the area, the next chance for precip will be at the end of the period as cold front drags across the area.
It will indeed be a cold start to the day in wake of yesterday's front, though lake effect cloudiness across northwest Indiana is doing its work as a natural blanket to keep things warmer in lee of the lake. High pressure across the plains will shift into the region today which allow for winds to slacken over what has been several windy/breezy days. The high center will pass to our south, so we will still maintain a lighter wind that will shift to southwest through the day. The wave will pass through Wisconsin tonight, providing us just increased cloud cover and a warmer night. Weak high pressure will fill in behind this weaker system for Thanksgiving day, which will result in mostly sunny conditions and temperatures in the lower to mid 40s, just a tad below normal.
The low and mid levels of the atmosphere will remain very dry, however some high cloudiness will once again make an appearance at times, especially later this afternoon and this evening. Temperatures today will be much cooler with highs only warming into the lower to middle 40s. Lows should range from the middle 20s over the eastern Ozarks to the lower 30s back towards I-49.
A cold front will push through the region and bring northerly winds back to the forecast area around 10kts, with some locations seeing gusts of 15-20kts by later this morning into during the day. /17/ Today through Tonight: Latest Rap and Satellite imagery showed an upper trough over the Mississippi Valley with a cold front moving through the region. For tonight expect the winds to taper off as high pressure builds into the region from the northwest as the upper trough persist across the region. Under clear skies and light north winds radiational cooling will provide lows from the middle 20s to the lower 30s.
A broad upper trof covered the eastern half of the United States. A short wave trof will pass through Alabama today and pull deeper Gulf moisture northeast across northern Florida. Some lingering mainly mid to high level clouds will remain across east and southeast Alabama today in advance of the short wave trof, but drier air at the the mid levels of the atmosphere will advect into central Alabama, keeping the area rain free today and tonight. Low level cold air advection will increase today as the short wave trof passes to the east of Alabama. Temperatures will be cooler than yesterday due north winds around 10 mph. With mostly clear skies and light winds tonight, temperatures will likely fall below freezing for areas along and north of I-59.
Tonight's temperatures should only fall back into the high 30s given the warmer temperatures just above the surface and 5 to 7 kt northwest winds.
The dry weather will be maintained tonight with temps remaining above freezing for lows. Temperatures will be well above normal with the pattern influenced by an upper ridge of high pressure.
911 AM EST Wed Nov 22 2017 Behind a cold front, high pressure will begin to move into the Ohio Valley today, bringing cool and dry conditions. Dry weather will continue through the end of the week, as temperatures slowly increase as the high moves off to the east. Near term guidance continues to show that the low level moisture will be decreasing within the few hours. The clear skies and light winds should allow for min temps to drop into the middle 20s on Thursday morning, followed by a slight increase in max temps on Thursday as opposed to Wednesday -- values in the lower to middle 40s.
High pressure will continue to strengthen across the region today, then remain in place through the rest of the week.
VFR will continue with a few thin high clouds overhead while an upper level high pressure ridge holds to our west. /issued 421 AM CST Wed Nov 22 2017/ The upper level ridge that has taken up residence over SOCAL will continue to dominate our weather over the holiday weekend.
Winds are breezy from the north northeast near the surface as cooler and drier air moves in this morning with building high pressure. /issued 300 AM CST Wed Nov 22 2017/ Upper analysis shows a southern stream trough moving into the northwestern Gulf of Mexico, a northern trough draped across the Great Lakes and Appalachian Mountains, and ridges well to the east and west. Radar imagery shows rainfall associated with the southern trough is moving south and will be a mostly coastal issue by daybreak. Observations show that the southern disturbance has drawn some drier air into the CWA ahead of the actual cold front to the north. The continental air mass associated with the northern upper trough will likely not reach the northern CWA zones until late morning and track across the area through the early afternoon.
A cold front has been moving through the region early this morning. Low pressure over the Gulf of Mexico will shift further east this afternoon as high pressure settles further south into South Texas. Anticipate lows to fall to the upper 30s across the Victoria Crossroads/northern Brush Country, and into the low to mid 40s further south.
High pressure will build Southward toward the region Today, with partly cloudy skies expected.
Temperatures so far this morning have been able to drop to the low to mid 70s with dew points in the lower 70s.
Further west, digging upper level trough and jet are driving the development of a low level disturbance along the boundary across the Central Gulf. Temperatures will climb into the low-mid 80s, with somewhat humid dewpoints in the upper 60s and low 70s.
A cold front is advancing southward across east Kentucky early this morning. With the high building in across the area tonight, a cold night is anticipated with lows well into the 20s. Ridging will remain in control across the Desert Southwest, with troughing in the East, as well as across the Pacific Northwest.
High pressure will dominate the wx today with clear skies. High pressure in control today producing clear skies and a light NW breeze this mrng becoming SW this aftn. A ridge of high pressure will shift ewd across srn WI today, with swly winds and weak warm advection beginning in the afternoon. Full sunshine and the weak WAA should be able to boost temps into the lower to middle 30s, before the high clouds arrive for late afternoon. Forecast soundings show the low levels of the atmosphere remaining fairly dry in srn WI, with better chances of saturation to the north.
In the low to mid levels of the atmosphere, an area of low pressure will develop over the central Gulf of Mexico this afternoon. In the upper levels of the atmosphere, a trough of low pressure will be located over the western Gulf of Mexico today.
A front will drift south as a weak cold front today for more rain, especially near the coast and in the north interior areas.
1005 AM EST Wed Nov 22 2017 A cold front will continue to move away from the area afternoon. High pressure will then build into the area for the second half of the week.
Warm front moving slowly from central Montana early this morning. This will limit the strongest winds to the higher terrain areas around the Little Rockies and Big Sheeps. The front will linger over the region overnight, and with high pressure sliding from Saskatchewan into North Dakota, could see a slight push of cold air under the incoming warm airmass.
302 AM MST Wed Nov 22 2017 Cooler air behind a weak backdoor front will be in place today. Meanwhile a strong upper high to the west will begin moving eastward and bring a return to warm daytime temperatures that will peak at about 15 to 17 degrees above normal on the weekend. Northerly flow on the east side of a strong upper high centered west of Baja CA will bring some high clouds over the area today.
An area of high pressure will move through the Northland early today, bringing milder air and a period of sunshine. Highs will be back to the lower to middle 20s, and without the strong wind. A weak area of low pressure will move into the Dakotas today and spread clouds and eventually light snow into the Northland from the west. Another area of high pressure will move through later today and early Thursday. Southerly flow will develop Thursday, bringing warmer air into the region. Expect partly cloudy skies and highs ranging from the middle 20s near the Canadian border to the lower 30s from central Minnesota into northwest Wisconsin.
Cold front nearing Fort Worth/Denton area and it should reach the CLL area 11 am and Downtown Houston 2-3 pm. Otherwise, a cold front moving across the state today will reach the terminals this afternoon and evening, resulting in northerly winds 6 to 10 knots and ceilings gradually lifting to IFR or MVFR through the end of the TAF period. Frontal lift with the incoming cold front weakening through the afternoon hours will probably see precip with the front but not nearly the intensity that is ongoing at press time around Galveston County.
716 AM EST Sat Jan 27 2018 A cold front will move east across the area late today and early tonight. High pressure will slide quickly across the Ohio Valley on Sunday ahead of a second cold front that will drop across the lower Great Lakes Sunday night.
541 AM CST Sat Jan 27 2018 09z/3am surface analysis shows cold front approaching the Illinois River.
A cold front arriving between 16Z and 19Z should bring an end to rains significant enough to alter cigs and vsbys; ahead of the front cigs and vsbys will be mainly in the lifr/ifr range with some outlying areas possibly seeing some dense fog. A trough axis is passing through the Central Plains tonight and this feature is sending a cold front south into the Southern Plains.
Otherwise, a cold front moving across the state today will reach the terminals this afternoon and evening, resulting in northerly winds 6 to 10 knots and ceilings gradually lifting to IFR or MVFR through the end of the TAF period. Frontal lift with the incoming cold front weakening through the afternoon hours will probably see precip with the front but not nearly the intensity that is ongoing at press time around Galveston County.
551 AM EST Sat Jan 27 2018 High pressure will continue shifting eastward today. A cold front will spread rain across the area tonight through Sunday night.
511 AM CST Sat Jan 27 2018 A cold front moved through the area last night however, with little cold air advecting in behind it, temperatures will remain well above normal today. Sunday a clipper system will force another cold front through the area. What is less in doubt is that this cold front will usher much colder air into the area. Highs Sunday will be in the mid to upper 30s across the northern CWA where the front will pass earlier in the day, to the low 50s across the south out ahead of the front.
433 AM MST Sat Jan 27 2018 Current surface analysis shows low pressure over western Ontario, with cold front stretching west-southwest into northern MN and ND. Cooler air will continue to push into the area over the weekend as the cold front to the north slides south through the region today. Highs today will range from the 20s across far northwest SD to the lower 40s across portions of southern SD.
