330 PM CDT WED OCT 12 2016 Strong cold front will continue to push south this evening with a cooler night on tap with diminishing winds. A much cooler day expected on Thursday with much of the area only warming into the 60s, with some places not climbing out of the 50s. In addition to the cooler temperatures, a disturbance will move out of the southern Rockies into the Southern Plains.
459 PM EDT Wed Oct 12 2016 A cold front will move through overnight into early Thursday, bringing showers and cooler weather to the region. High pressure will build in providing dry weather and cooler temperatures.
Models show the approaching cold front moving into northwest portions of the PAH forecast area this afternoon, pushing just southeast of our region early in the day Thursday. By Thursday afternoon, high pressure north of our region will quickly be sliding east. Models continue to bring an upper level trof west of our region late Thursday night.
345 PM CDT Wed Oct 12 2016 Cold front continues to march southeast, snaking along the Red River and slowly entering the far northwest fringes of the CWA. So expect a dry forecast tonight even with frontal passage as cooler air works farther south through the overnight hours.
A cold front is currently near the Pecos River. /issued 250 PM CDT WED OCT 12 2016/ The much-advertised cold front is currently moving south through the area, a bit quicker than previously expected. Winds behind the front are northeasterly, with gusts to around 20-25kt, though the leading edge of the cooler air is lagging the front by about an hour. The cooldown overnight will be hampered somewhat by cloudcover, though it will still be noticeably cooler, with lows in the middle to upper 40s north to the 60s through the Rio Grande Valley. Given cold air advection in the wake of the front tomorrow as well as widespread cloudcover, temperatures will be below normal in the middle 60s north to upper 80s south, around 15-20 degrees cooler than today for locations along and north of I-10.
139 PM EDT Wed Oct 12 2016 Dry and cool high pressure will remain in the forecast area through tonight. A cold front will approach from the northwest Thursday. High pressure will ridge into the area from the north behind the front over the weekend. The surface pressure ridge will remain in the forecast area through tonight. Aloft, broad troughing will be over the area. Expect this cloudiness will dissipate with the loss of heating this evening with a little upper cloudiness associated with the broad upper troughing. A small bubble of high pressure will break off from the main wedge and settle over the area tonight. Temperatures should warm further ahead of the next weak cold front as cold advection shuts off at low levels. The weak cold front will move through the area from the northwest overnight.
149 PM EDT Wed Oct 12 2016 High pressure to our east will allow for abundant sunshine, above normal temperatures, and an increasing southerly breeze this afternoon. A cold front will pass through on Thursday morning and early afternoon bringing showers to mainly the northern and central mountains.
Fair weather continues today as a weak upper level ridge shifts east into the Great Basin.
The main upper trough currently moving through ND will head east towards MN/WI today. Even with winds staying in the 5 to 10 kt range and the warmer air mass starting to move into the area, think that with clear skies and fairly dry dewpoints we will get down into the upper 20s in many areas again tonight.
The larger and more uniform echoes on KBYX doppler radar currently to the west/southwest of the Lower Keys are chaff.
High pressure centered over the northeast United States will shift offshore tonight, followed by a cold front crossing the region Thursday.
244 PM CDT Wed Oct 12 2016 Upper level pattern across the CONUS characterized by upper trof over the central plains, which has brought a cold front into the srn plains today. Cold front draped across N TX/central OK will continue to make progress sewd into our region by tonight and will bring some sct convection and cooler air along with it.
In the upper levels, an elongated ridge remained centered over northern Mexico, with a trough extending from the Canadian prairies to southern California. This trough will move eastward today, and this should give the surface boundary a slow push into Arkansas.
/issued 406 AM CDT WED OCT 12 2016/ Latest WV imagery and UA analysis shows mostly zonal flow aloft on top of weak flat ridging acrs nrn mexico into srn tx. At the sfc, high pres over the ern seaboard was ridging sw acrs LA/ ern TX, resulting in a lt e/se wind acrs the area. On Thursday, the nrn stream trough will push a weak cold front southward toward the area, but the front will stall prior to reaching our NW zones.
311 PM CDT WED OCT 12 2016 A cold front currently extends from far northwestern Arkansas to south-central Oklahoma. Temperatures will be considerably cooler Tonight with lows in the 40s and 50s.
140 PM EDT Wed Oct 12 2016 High pressure will maintain dry weather today before showers return with a cold front early Thursday. High pressure will continue to slide eastward as a cold front approaches. Southerly flow in advance of the boundary and mostly sunny skies should support high temperatures that are about 10 degrees warmer than average today. Shower chances will increase after midnight as the upper trough over the northern Great Lakes swings a cold front toward the region. Front will continue to make progress across the upper Ohio Valley early, followed quickly by building high pressure. With northwest flow and moisture lingering in the high terrain, have kept chance PoPs in the forecast through Thursday afternoon.
High pressure will fill into the area tonight bringing light winds to much of the area. East of the James River and especially across parts of northwest Iowa winds will remain light all night and these locations will see the highest threat for a killing freeze and widespread frost.
143 PM EDT Wed Oct 12 2016 Cool and dry high pressure will extend over the area from the north through tonight.
210 PM EDT Wed Oct 12 2016 Dry and cool high pressure will remain in the forecast area through tonight. A cold front will approach from the northwest Thursday. High pressure will ridge into the area from the north behind the front over the weekend. The surface pressure ridge will remain in the forecast area through tonight. Aloft, broad troughing will be over the area. Expect this cloudiness will dissipate with the loss of heating this evening with a little upper cloudiness associated with the broad upper troughing. A small bubble of high pressure will break off from the main wedge and settle over the area tonight. Temperatures should warm further ahead of the next weak cold front as cold advection shuts off at low levels. The weak cold front will move through the area from the northwest overnight.
1134 AM MDT Wed Oct 12 2016 Latest upper air analysis has a long wave trough moving onto the Northern Plains. Further west a short wave trough was moving onshore. At the surface a cold front had moved south through Kansas and Colorado. Early this morning there may be some lingering rain over the Southwest Nebraska counties where weak lift persists before the 500mb trough axis moves through. North winds will be strongest this morning then become light this afternoon as high pressure builds in. Highs today will be Tonight lows will fall into the lower to mid 30s. A weak upper level short wave trough does move in from the west during the overnight hours, but the lift is very weak. Thursday morning kept the forecast dry as the weak short wave trough moves through for the same reasons as stated previously.
248 PM EDT Wed Oct 12 2016 Dry, mild weather will continue tonight, as high pressure slowly retreats off the coast. Showers are expected to cross the region Thursday, associated with a cold front.
Temperatures will remain cool with high pressure centered over the area.
A weak cold front pushing down across central Texas is expected to drop to the Hill Country late tonight. Due to cloud coverage across the Hill Country on Thursday, highs may only get to the lower 80s while rest of the area gets into the mid 80s to near 90.
207 PM EDT Wed Oct 12 2016 Dry and cool high pressure will remain in the forecast area through tonight. A cold front will approach from the northwest Thursday. High pressure will ridge into the area from the north behind the front over the weekend. The surface pressure ridge will remain in the forecast area through tonight. Aloft, broad troughing will be over the area. Expect this cloudiness will dissipate with the loss of heating this evening with a little upper cloudiness associated with the broad upper troughing. A small bubble of high pressure will break off from the main wedge and settle over the area tonight. Temperatures should warm further ahead of the next weak cold front as cold advection shuts off at low levels. The weak cold front will move through the area from the northwest overnight.
Troughing will further deamplify downstream through the southern Rockies Thursday though quasi-zonal flow south of the primary northern stream jet core will keep H5 heights near a 585dm range.
300 PM EDT Wed Oct 12 2016 A strong cold front will bring showers and isolated thunderstorms to the region later this afternoon into this evening. Much cooler and drier air will follow in behind this front later tonight into Thursday.
Dry weather can be expected through Thursday as a low amplitude ridge sets up over the region continuing a warming trend.
1237 PM CDT Wed Oct 12 2016 The low cloud deck is eroding quickly and all terminals will be mainly clear within the next hour. Expected these to move north from the Coastal Plains to along the Highway 77 corridor by midday with a thunderstorm or three possible this afternoon at max heating. A weak cold front drops south into Central Texas late tonight into Thursday as a weak mid level trough and a favorable quadrant of a small upper level jet approaches from the west. Upward forcing by the front, trough, and jet on this moisture will generate showers and thunderstorms Thursday. With the Subtropical Ridge nearby and PWs still near or below normal, only isolated coverage is expected.
As high pressure continues to build into the Dakotas today, expect a clearing trend through the day. The rest of the short term is dry with a warming trend as high pressure moves east and southerly flow returns.
344 PM CDT WED OCT 12 2016 (Tonight and Thursday) As of 330 pm, a strong cold front was south of Abilene, and heading south through the Big Country at around 20 mph. Although much cooler temperatures will follow behind this front, cooling tonight will likely be moderated somewhat by the development of low clouds after midnight.
133 PM MDT Wed Oct 12 2016 Water vapor imagery shows upper trough now crossing the cntrl CONUS with upper ridging building over the Pac NW. Clear skies will continue tonight and Thursday as high pressure remains in control along with upper ridging. Return flow will set up on the backside of the high tonight into Thursday. This will bring slightly warmer temps to the area tonight with lows in the mid 20s to mid 30s.
255 PM EDT Wed Oct 12 2016 High pressure pulls off to the east toward the Canadian Maritimes today while an upper level trough approaches from the west. A cold front will cross the area Thursday night with showers along and ahead of it.
340 PM CDT Wed Oct 12 2016 Latest surface analysis showed a 1026mb high over northeast United States with ridge axis extending southwest to Georgia to Mississippi. An inverted trough was located over west Gulf of Mexico. With the high pressure not as strong as previous days, the pressure gradient has relaxed today. A cold front was located from Michigan to north central Texas. wedge of drier air in the same area of the ridge axis have kept dewpoint values in the with 50s across the north zones and 60s along the coast. Upper air analysis showed an anti-cyclonic circulation just south of Texas with the ridge axis extending east to Florida. 18 Cold front will approach west Tennessee and northwest Louisiana by Thursday and stall.
A fast moving cold front set to race across the Ohio Valley tonight extended from the U.
302 PM CDT WED OCT 12 2016 19z/2pm surface analysis shows cold front approaching the I-55 corridor. Once the front passes, skies will gradually clear from west to east overnight as a much cooler/drier airmass flows into the region. With strong high pressure firmly in control of the weather, sunny and cool conditions are expected on Thursday with highs only in the upper 50s and lower 60s. The affects of the chilly high pressure will linger on Thursday night, as mostly clear skies for a majority of the night help low temps dip into the lower 40s.
Strong cold front currently moving through the Tulsa metro early this afternoon with gusty north winds behind boundary. Cold front moving through northeast Oklahoma late this morning, currently just north of I-44.
330 PM MDT Wed Oct 12 2016 A weak trough moving ashore over southern California continued to spread cirrus, mainly of the thin mostly transparent variety, over the region this afternoon. Models suggest isolated light showers will develop over the higher terrain south of the I-70 corridor as the trough sweeps across the Great Basin then overhead late tonight.
201 PM EDT Wed Oct 12 2016 Rain-free, mild weather will continue through tonight, as high pressure slowly retreats off the coast. Showers are expected to cross the region Thursday, associated with an incoming cold front.
122 PM EDT Wed Oct 12 2016 High pressure will allow for dry conditions across the region through most of the daytime hours today. A cold front will move through tonight bringing showers and cooler weather to the region.
Cool tonight with winds turning sw to westerly allowing for warmer air to begin its return. Much warmer conditions for Thursday under westerly flow aloft with winds becoming breezy over se Wy around the mtns.
320 PM CDT Wed Oct 12 2016 Current surface analysis places high over the northern into the central plains, while cold front stretches from the midwest into the southern plains. Upper level analysis places trough pushing into the midwest with ridge building over the Northern Rockies. skies will continue to gradually clear out as aforementioned ridge gradually broadens out towards the east. quiet weather with warming temperatures expected as ridge continues to develop into the area.
306 PM EDT Wed Oct 12 2016 Upper air pattern consists of a 500 mb trough in the northern plains which heads into the upper Great Lakes by this evening and into the lower Great Lakes by Thu morning. A high latitude blocking ridge from AK into ern Siberia and trough over the ne Pacific will result in a low amplitude progressive pattern across the nrn CONUS with several pacific origin shrtwvs bringing rounds of precipitation to the nrn Great Lakes. Otherwise, the winds should still be light enough for good radiational cooling which will allow temps to drop into the lower 30s inland.
Hints of a weak Denver cyclone have resulted in light northerly winds West of Denver have also helped to keep stratus intact even through Northern Douglas county. Warmer day on Thursday as low level moisture finally scours out and a return to Partly cloudy skies on the plains.
1137 PM CST Tue Dec 20 2016 Weak high pressure will allow decoupling of the atmosphere and therefore another relatively cold night with lows ranging from the middle teens across the north to the lower 20s in the south. A weak cold front will move across the area on Wed/Wed night, but no precipitation is expected. A cutoff low west of Baja California will eject northeastward into the Four Corners region on Thu night in response to an approaching upstream trough. Meanwhile, a longwave trough will approach the west coast and eventually develop into a large low pressure system somewhere across the central CONUS. Models have come into much better agreement compared to 48hrs ago, and it now appears that the maturing low pressure system will be located somewhere between Oklahoma City, OK and Williston, ND.
Some freezing fog is occurring early this morning but is confined to mainly areas near the Tennessee River. Will keep Freezing Fog Advisory going for much of the forecast area but will consider canceling portions of it later this morning if more fog does not develop. High pressure continues to cover much of the southeast U. As a result, temperatures will be warmer today with highs expected to be in the low to mid 50s.
And with temperatures already near or below freezing in those same northern tier counties, we are strongly considering changing a portion of the DFA into a Freezing Fog Advisory. Will make decision on Freezing Fog Advisory and have update forecast done by 830 pm.
Cooler. Have increased snow/rain coverage across the area this evening associated with the passage of a cold front.
248 AM EST Wed Dec 21 2016 High pressure through tonight.
1157 PM EST Tue Dec 20 2016 Maintenance of a dry low level environment in southwest flow will ensure a clear sky holds across the lowest 10k ft through Wednesday morning. Low pressure tracking through the northern Great lakes will bring a thickening and lowering cloud into SE Michigan Wednesday afternoon. Southeastern Michigan will remain within the higher pressure gradient, tucked under the consolidated higher upper level kinematic axis. Model data shows deep dry air holding firm in the lowest 10 kft agl at DTW right through the cold front passage.
300 AM EST Wed Dec 21 2016 High pressure will extend across the Southeastern U.
1133 PM EST Tue Dec 20 2016 Low pressure over Ontario will move east into Quebec tonight as high pressure begins to build over the lower Ohio valley.
Expect an initial surge of gusty winds with the cold front, then winds will pick back up again later Wed morning. Strong trof moves through the Rockies and into the Plains for the weekend. A fast moving low pressure system will bring scattered rain and snow showers tonight, mainly over northwest areas. Gusty northwest winds will develop late tonight behind a low pressure trough, with the strongest winds expected on the SD plains.
Low pressure has moved into North Dakota early this morning. Tight surface gradient behind the low has brought strong west winds to Northeast Montana with gust as high as 68 mph overnight. The low will continue to move to the east this morning and surface gradient will relax allowing the winds to diminish.
315 AM EST Wed Dec 21 2016 Max temperatures ended up around the freezing mark yesterday, and looks like we should solidly rise above 32 degrees today (mid 30s) with the milder start and southerly winds, as 925 mb temps progged to rise into the 1 to 2 C range (not that we are mixing up that high). Much of the lift will be used up just to saturate the low levels, and thus expecting any light snow accumulations to be less than an inch.
423 AM EST Wed Dec 21 2016 High pressure will be centered near the forecast area today and tonight.
342 AM CST Wed Dec 21 2016 Water vapor imagery/RAP 500mb analysis showing a well defined mid- level trough swinging eastward through North Dakota. There is a slight chance for some freezing drizzle in the afternoon as well across that area with loss of cloud ice. Plan on highs across the area in the lower to middle 30s.
Surface analysis this evening shows an area of high pressure in place centered over Alabama. However, with dew points lingering in the low 30s/upper 20s and light/calm winds, we are still expecting areas of dense freezing fog through the early morning hours. As such, the Freezing Fog Advisory remains unchanged. Among low visibility hazards, freezing fog can cause light icing on bridges/overpasses, or on roadways at higher elevations.
407 AM EST Wed Dec 21 2016 High pressure will build over the area today.
Meanwhile a ridge of high pressure moving into the two state area will keep conditions dry overnight.
A cold front will near ktxk just beyond the scope of this TAF cycle and will veer winds to the north. Current temperatures are running in the lower 50s from Tyler to Shreveport, but as cold as 41 in Monroe with clouds nearly overhead. A warmer day is expected on Wednesday with high temperatures again very near normal right around 60 degrees.
Precipitation type may be a challenge early this morning across the southeast corner of North Dakota where temperatures have risen to the freezing mark or even slightly above. NWS Bismarck reported sleet and freezing rain earlier with some enhanced radar returns, along with Jamestown and Valley City now reporting unknown precip as of 10z. Therefore, have continued the blowing snow mention through the afternoon for the far northwest but reduced the chances for southeast North Dakota with the warmer temperatures and mixed precipitation potential.
412 AM EST Wed Dec 21 2016 High pressure will remain in place across the area today allowing for seasonable temperatures.
High pressure across the region will allow for IFR cigs and vis overnight, with surface obs and spotter reports indicating patchy dense fog already forming.
A cold front will swing through during the day on Wednesday, but with good mixing and the upper system staying well north it will only be a glancing shot of cooler air. The primary concern will center around a strong upper low that will track across the northern/central plains on Christmas. Given the current forecast track of the upper low, it appears thunderstorms and possibly even severe thunderstorms will be our primary hazard with this system on Christmas, with most of the snow currently expected to be over the Dakotas. Christmas Eve into Christmas Day: The 12Z GFS/ECMWF/GEM and a vast majority of ensembles are all indicating above freezing 850mb air for Christmas Eve through Christmas Day.
Light and variable winds will become predominantly southerly tonight and will shift to the north as a cold front passes by from northwest to southeast late morning into the afternoon. Northerly winds could gust to over 20 knots behind the the cold front--especially across western Oklahoma. Light and variable winds will become predominantly southerly and will shift to the north tomorrow as a cold front passes by from northwest to southeast.
121 AM EST Wed Dec 21 2016 High pressure will extend across the Southeastern U.
111 AM EST Wed Dec 21 2016 A frontal system off the coast will move farther offshore tonight as high pressure builds in.
The high temperature forecast was increased a couple degrees, so expect readings near, or a couple degrees above the seasonal averages on the strength of warm advection in advance of that system.
400 AM EST Wed Dec 21 2016 High pressure will extend across the Southeastern U.
Moderate westerly flow aloft will continue which will keep some gusty winds going over mountain ridges. For pops, will keep them out overnight through 12Z, then will need "chance"s in the high mountains on Wednesday. There is a departing 150 knot upper level speed max over northern Colorado, while there will also be shallow anticyclonic upslope flow on the plains behind Wednesday's cold front. Should see at least areas of light snow over the high country with sufficient mid level moisture.
A cold front will veer light southwest winds to the northwest at KABI and to the west at KSJT by early evening. Flow aloft will generally remain zonal or weakly ridging. Considering how warm we have gotten today, have trended temperatures upward for Wednesday as well with much of the area getting into the lower 70s. 20 (Wednesday Night through next Tuesday) The cold front will push south across west central Texas Wednesday evening and Wednesday night.
Biggest weather of note for today will be the potential for freezing fog early this morning. With the clearing skies allowing temperatures to drop to near the dewpoint some locations could see freezing fog reduce visibilities. Quiet and slightly warmer weather will continue overnight and into tomorrow.
