856 PM CDT Tue Nov 1 2016 Another area of ci clouds rotating arnd a large area of high pressure, will move across the TN valley after midnight. The upper level ridge will remain in control of the weather again on Wednesday. Now with that said we are still forecasting afternoon highs in the low to mid 80s for the TN Valley.
A cold front will move through the area Wednesday night.
Expect quiet weather overnight as high pressure remains in control. Dry weather and above normal temperatures will continue to prevail across the forecast area over the next 24 hours, as high pressure at the surface and aloft remain in control of our weather. Lows tonight will also be a tad warmer than previous nights as temperatures range from the mid 50s to lower 60s.
/issued 351 PM CDT Tue Nov 1 2016/ Partly cloudy skies with temps in the low to mid 80s today.
Front will move back south tomorrow afternoon as longwave trough progresses across Northern Plains into Great Lakes region. Precipitation chances spread into the area tomorrow as a cold front moves into and through the area Wednesday and Wednesday night.
have only mentioned the lower flight rules for BPK and HRO.
534 PM MDT Tue Nov 1 2016 A cold front will move across the area after midnight shifting winds to a northern direction, speeds generally 10 mph or less. Afternoon temperatures cool about 5f to 7f per 850mb temperatures with readings in the low to mid 60s.

1201 AM CDT Sun Apr 9 2017 A chance for thunderstorms Sunday and Sunday night, then a cool rain Monday, are the highlights of the short term forecast. Aloft, southwest flow was noted, ahead of trough moving onto the West Coast this afternoon. Also noted was plume of mid level moisture from base of trough in the northern Baja into the Plains. Southwest flow aloft will continue overnight as western trough approaches. Western trough will enter the Plains on Sunday, closing off an upper low in northwest Nebraska as per GFS. Warming surface temps combined cooling aloft attendant to approaching upper trough/low will lead to steep mid level lapse rates of 8 C/km and MUCAPE values over 2000 j/kg ahead of dryline sweeping east. Continued chance for showers or storms will favor northeast Nebraska Sunday night where core of upper low will track.
112 AM EDT Sun Apr 9 2017 High pressure will be in control into through Monday. Upper level ridge will strengthen overhead through Monday.
Deep layer ridging will build over the Southeast today, with highs climbing into the upper 70s to low 80s.
Expect tonight to be much milder than the last two as the continued eastward progress of the high will establish a modest pressure gradient over the area, and prevent winds from decoupling. Temps will also rise accordingly, roughly 10 degrees warmer than this afternoon based on low-level thickness trends. Unseasonably warm temps will continue into Monday and Monday night as the East Coast upper ridge amplifies ahead of a trof moving through the Plains.
319 AM EDT Sun Apr 9 2017 A narrow ridge of high pressure will crest over the region early today and will shift offshore south of New England this afternoon. A warm front will pass by to the north tonight and will stall over southern Canada on Monday.
330 AM MDT Sun Apr 9 2017 Southwest flow aloft continues across the northern Great Plains ahead of an approaching upper trough now over the Great Basin. The western trough will cut off over Wyoming this afternoon and cross near the SD/NE border tonight. Will also issue an advisory for the Spearfish area with mention of 2 to 5 inches since it looks like the higher elevation of the foothills would probably reach advisory criteria. which will stay near or above freezing most of the night. Mainly dry and milder conditions will develop for the first half of the week as weak ridging passes over the region.
323 AM CDT Sun Apr 9 2017 Currently, an upper level trough was over the US Rockies with southwesterly flow across the Dakotas. At the surface, a low pressure system was centered over central Nebraska/Kansas. A surface Canadian high pressure system was centered over north central Canada with its southern extent in the form of a cold front draped west- east across northeastern Montana/North Dakota/southern Manitoba. The upper level low over the Rockies is forecast to become a closed low as it moves east across Wyoming today and SD/NE tonight. Lows tonight should be in the 20s with the influence of the Canadian high pressure system dominating over ND.
423 AM EDT Sun Apr 9 2017 A ridge of high pressure will slide just off the Eastern Seaboard today.
As for highs this aftn readings will be cooler across nern Co with readings in the mid 50s to around 60. At this point expect gusts fm 40 to 50 mph over much of the plains with the highest gusts closer to the WY-NE border.
Tonight Through Monday An upper ridge continues over Arkansas this afternoon but will slowly move east tonight. By Sunday afternoon the ridge will be over the eastern U. and an upper low will move into the northern Plains. The upper low then moves into the upper Midwest Monday, increasing southwest flow over Arkansas. A cold front will move through the Rockies tonight and into the Plains by Sunday morning. High temperatures Monday will be considerably cooler than Sunday.
249 AM EDT Sun Apr 9 2017 High pressure will continue over area today then move offshore tonight.
Negatively tilted NW-SE oriented upper trough will move across West and Central Montana with the base of the trough moving across Wyoming and Colorado. Deep moisture and good lift ahead and along the trough axis today will bring widespread precipitation to Central and Southern Montana. An upper low forms at the base of the trough by midday and moves to the east this evening taking most of the moisture with it. The trough over Montana will split with the drier northern branch lingering over the central part of the state tonight. The northern stream trough moves through Northeast Montana on Monday but it looks like it will be dried up by that time.
19z/2pm surface analysis shows ridge of high pressure extending from Quebec southward to the Gulf Coast. a 991mb low is noted over Manitoba, with a cold front trailing into the Northern and Central Plains. The amount of cloud cover will influence Sunday afternoon high temperatures, resulting in slightly cooler readings than previously forecast across the W/SW KILX CWA. As the cold front nears, a few showers will develop late Sunday night. Models have correctly backed off on the areal coverage of precip due to a lack of deep-layer moisture from the Gulf of Mexico, which will be largely blocked by surface ridging over the Deep South. As the high slowly shifts eastward and moisture return becomes more robust, rain chances will increase by Monday afternoon and evening.
622 AM EDT Sun Apr 9 2017 High pressure works its way off the Mid-Atlantic coast through Monday night.
the passage of the upper low associated with the cold front may trigger a few rw/trw.
330 AM EDT Sun Apr 9 2017 High pressure will extend over central North Carolina today, then drift offshore Monday.
A very large warm-up is expected Sunday into Monday as the ridge shifts east owing to south-southwesterly flow and good warming of the column as heights grow in mid to upper levels. The increasing sun angle and virtually no clouds will also equate to very warm afternoons as dew points are slow to recover into the lower 50s on Monday. Some mid level clouds may increase late Monday night in northwest AL within the mid level theta-e ridge that shifts southeast.
330 AM EDT Sun Apr 9 2017 High pressure centered along the Carolina coast early this morning will move out to sea slowly.
356 AM EDT Sun Apr 9 2017 Dry and warmer weather will continue today but shower and thunderstorm chances return on Monday. High temperatures today will be in the low to mid 70s but it will be windy with southwest winds of 25 to 35 mph.
The area of low pressure will continue to lift to the northeast today and into Great Lakes region late tonight into Monday. The pressure gradient will tighten across the area today ahead of the low resulting in breezy conditions. Another warm day is in store for the Missouri Ozarks and southeastern Kansas this afternoon as highs top out in the upper 70s to the lower 80s. A cold front will spread across Kansas today and into the area tonight. Temperatures will be slightly cooler Monday as highs in the lower 70s occur.
Convection firing along leading edge of thermal trough/cold front sliding into the forecast area with support aloft from mid-level jet streak ripping northeast. Convection over Northwest Colorado will keep driving stronger winds down and have decided to re-issue the wind advisory through today with tight pressure gradient in place thanks to passing cold front and strong CAA on back side. Fruit trees) in the lower valleys of West-Central Colorado and East-Central Utah in full bloom, will go ahead and upgrade the freeze watch to a warning. Should see several hours below the freezing mark between midnight and 9 am with the coldest temps expected right around sunrise. Monday night will be warmer with temps staying above freezing in the lower valleys.
Highs today will climb into the upper 70s to lower 80s inland and the low to mid 70s along the coastal areas. Overnight lows will be 5-10 degrees warmer, with lows generally in the lower 50s inland and the upper 50s to lower 60s along the coast.
1212 AM CDT Sun Apr 9 2017 Cirrus clouds have kept temperatures much cooler than forecasted today. Tonight a cold front will push through the area, shifting winds to the northwest.
Low pressure will then move into the western Great Lakes by Monday morning.
400 AM CDT Sun Apr 9 2017 Despite increasing cloud cover, high temperatures today should be slightly warmer than the previous day owing to a much warmer start early this morning and strong and gusty southerly/southwesterly surface/low level winds. A cold front will also be approaching this area tonight as an upper level low moves eastward into the northern Plains. Lows tonight will be unseasonably warm due to the cold cover and continued southerly surface winds ahead of the approaching cold front. A surface cold front will track thru the CWA providing good moisture convergence and have some measure of upper level support.
The low pressure area over the central Great Plains will track into central WI tonight with the most active pcpn area across nrn WI. In the lower levels a low will track from northern or central WI into the eastern Great Lakes. There are still some model differences on the timing of the cold front. At the moment the ECMWF is a compromise between the cooler NAM and warmer GFS. Some big differences in temperature guidance though the Superblend is close to what the warmer GFS guidance is showing for max temp on Bufkit.
The only other change for this update was to increase sky cover in the north beginning after midnight as low clouds in Canada move south behind a cold front that had entered northwestern ND and will move south across the state early this morning. Trended the POPs down into the lower 20s across the central and left around 30 southwest.
The weather system that brought gusty winds to the area yesterday will leave cooler temperatures behind today and Monday. Much warmer readings will then prevail through the remainder of the work week.

402 AM EDT Sun Apr 9 2017 High pressure will be in control into through Monday. Upper level ridge will strengthen overhead through Monday.
An upper trough, currently entering the central and southern Rockies, will move east across the Central Plains tonight.
Upper level ridge for Sunday with partly to mostly sunny skies. The next upper level trough and cold front will move through the area Sunday night into Monday. Breezy west winds Monday after cold frontal passage. A weak upper level ridge will shift east across the region Sunday, resulting in mostly dry conditions. The upper low with this next system will swing across the area Monday afternoon and evening, thus expect to see varying chances of showers continue afternoon and evening.
324 AM EDT Sun Apr 9 2017 Current satellite loop shows mostly clear skies over the region this morning as high pressure continues to dominate the weather pattern. This ridge is centered over GA and the Carolinas right now but it is expected to drift slowly east to just off the Mid Atlantic coast through Monday afternoon. This ridge becomes elongated but continues to keep North and Central GA dry through the short term.
309 AM MST Sun Apr 9 2017 Cooler temperatures can be expected today in the wake of a weak cold front and low pressure system, with high temperatures in the upper 70s and lower 80s across the lower deserts.
425 AM EDT Sun Apr 9 2017 High pressure will be situated east of the region allowing for southerly flow and warm conditions today and Monday.
A trough moves across West Texas Sunday night sending a weak cold front into the Permian Basin on Monday. High pressure behind the front will move south providing a moisture low level return flow that will reach the mountains.
310 AM EDT Sun Apr 9 2017 High pressure will extend over central North Carolina today, then drift offshore Monday.
A front will pass Sunday night making for a cooler but pleasant day Monday as relatively light winds rotate around the dial by Monday night back to the south.
511 AM EDT Sun Apr 9 2017 A ridge of high pressure will slide just off the Eastern Seaboard today.
355 AM EDT Sun Apr 9 2017 High pressure works its way off the Mid-Atlantic coast through Monday night.
1103 PM MDT Sat Apr 8 2017 Current surface analysis shows cold front now east of the forecast area. Upper level analysis shows ridge axis to the east of the region, with southwest flow ahead of trough moving across the west coast states. Unsettled and much cooler weather can be expected through the rest of the weekend as west coast trough moves quickly east and low pressure develops within the trough as it moves over the region later on Sunday and Sunday night. The northern Black Hills and the Bear Lodge Mts, especially the higher elevations, still have the highest potential for significant snowfall of 6 inches or more due to colder air aloft and upslope enhanced snow potential. Mainly dry and milder conditions will develop behind exiting system into midweek, as weak ridging passes over the region.
139 AM EDT Sun Apr 9 2017 High pressure and a dry airmass will provide for seasonably warm temperatures through the weekend.
with dewpoints gradually rising into the lower 60s across the forecast area. The more likely scenario favors convective development across eastern/southeastern KS this evening along the advancing cold front.
624 AM EDT Sun Apr 9 2017 Dry and warmer weather will continue today but shower and thunderstorm chances return on Monday. High temperatures today will be in the low to mid 70s but it will be windy with southwest winds of 25 to 35 mph.

641 AM EDT Sun Apr 9 2017 High pressure will be situated east of the region allowing for southerly flow and warm conditions today and Monday.
01 UTC surface analysis shows an area of high pressure just over the region. With high pressure in place over the region, expect another clear and chilly night for early April. Low temperatures once again are expected to drop into the lower 40s and it wouldn't be too surprising to see some of the cooler inland spots drop into the upper 30s before sunrise. Mostly clear skies are expected with highs generally in the upper 70s to low 80s, and overnight lows in the low to mid 50s.
This activity should be focused over parts of central and southeast SD through the morning as the lower levels remain capped and drier. The main threat from the strongest storms would be about half dollar hail with a freezing level about 9000 feet AGL and wind gusts around 40 mph. On Monday the main upper level low tracks across the region with precipitation continuing over much of the area through the morning. With the clouds and precipitation stayed on the low side of guidance with highs mainly lower 40s - to some mid/upper 40s through our lower northwestern IA zones. Surface ridging builds into the area on Monday night with decreasing clouds and dying winds. This will be conducive to some radiational cooling, so again trended to the low side of guidance with lows mainly mid and upper 20s.
428 AM EDT Sun Apr 9 2017 High pressure will remain across the Southeast today, then shift over the Atlantic on Monday.
603 AM EDT Sun Apr 9 2017 A high pressure system provide dry weather today and Monday.
145 AM EDT Sun Apr 9 2017 Ridge/valley temperature split playing out as advertised, currently 34F in Paintsville and 37F in Quicksand. With these temperatures already approaching current dewpoints, not expecting too ridiculous of a dropoff from current readings, but will still likely see freezing/sub-freezing values prior to dawn in sheltered valleys. Ridges will continue to plummet with drier air aloft intact as evidenced by dewpoints in the teens. This will lead to milder weather through the rest of the weekend, modest ridge/valley splits at night and the continuation low relative humidity in the afternoon hours. Another sharp ridge valley split is expected Sunday night with valleys dipping into the upper 30s and ridges likely staying in the low 50s. Monday will be dry out ahead an approaching cold front, with highs in the mid to upper 70s.
An upper level trof will be moving eastward across CO today and is expected to continuing bringing some showers to the central mtns into the evening hours. As the trof moves east tonight, the showers will end. Temperatures today will be cooler than yesterday by around 10 degrees in most areas, but will be close to average.
327 AM EDT Sun Apr 9 2017 A ridge of high pressure over the area will move to the Appalachian Mountains today.
327 AM EDT Sun Apr 9 2017 A high pressure system provide dry weather today and Monday.
354 AM CDT Sun Apr 9 2017 A warm front stretched from Nebraska, through northwest Iowa, into northern Wisconsin during the overnight hours. A warm front was also situated in western Iowa. For today, have continued to go above guidance for the high temperature forecast.
120 AM EDT Sun Apr 9 2017 High pressure will extend over central North Carolina today, then drift offshore Monday.
A cold front tonight will usher in a period of cold unsettled weather lasting through the end of the week. Moisture is being eroded away as an area of high PW begins to shift south and east today with the cold front moving in from the northwest later.
207 PM CST Tue Feb 21 2017 Upper low centered over Arkansas continues to make slow eastward progress, eventually taking the cloud cover along and east of the Oklahoma/Arkansas line with it. Even warmer temperatures are on tap tomorrow as winds shift to the south and southwest.
347 PM CST Tue Feb 21 2017 A couple short wave troughs moving over the region along with a surface cold front dropping south on Wednesday will bring an increase in clouds along some chances of light rain/sprinkles later tonight and Wednesday. It will be a mild night across the region with lows in the mid 30s to the lower 40s.
300 PM CST Tue Feb 21 2017 Ridge over the east coast and large cutoff low over Arklatex. , will likely fall to near or just below freezing. Not as warm Wednesday behind a weak cold front, but still much warmer than average for this time of year.
222 PM CST Tue Feb 21 2017 An upper ridge across the forecast area will move east and be replaced by westerly flow aloft by early Wednesday.
938 AM PST Tue Feb 21 2017 Slightly warmer today, with a slight chance of showers over portions of Orange and San Bernardino Counties.
Freezing levels across the area will drop to 2000 feet elevation tonight and to 1000 to 2000 feet tomorrow morning. The lower conditions will persist through mid-morning Wednesday.
251 PM MST Tue Feb 21 2017 Upper ridging across the central CONUS continues to slide eastward into the upper Midwest. an upper trough is moving onshore with upper flow across the western CONUS and the CWA transitioning to a more active southwesterly flow. In the low levels. strong thermal ridge is crossing the northern Plains with gusty W/SW flow across northeast WY and far western SD. Rain showers are expected develop over the next few hours ahead of a wave crossing WY/MT and a cold front crossing the area. NW SD could see some showers develop during the day into the evening as a backdoor cold front slides into northwest to central SD. Temps will be cooler tomorrow with highs in the upper 40s to upper 50s.
Though overcast, clouds were thin enough across the north to allow some sunshine to filter through and warm locations to around 70 degrees, with some spots climbing into the low 70s. For Wednesday, conditions should slowly dry out across the south as the closed low slides east and cuts off the moisture transport to our area. Highs will range from the lower 60s there to the upper 60s in the southern valley where some sunshine may be able to work in by late afternoon.
352 PM CST Tue Feb 21 2017 (Tonight and Wednesday) As upper ridging builds over the area from the southwest, northwesterly flow aloft over the area will back to the west tonight and will be out of the southwest by tomorrow. Looking for sunny skies tomorrow with afternoon highs around 20 to 25 degrees warmer than average, 85 degrees at Abilene (normal 62 degrees), and 89 degrees at San Angelo (normal 65 degrees. ) Morning lows tomorrow across the area will also be warmer than average with lows mostly in the mid 40s under clear skies (normals for the area are in the upper 30s.
This will be caused by an approaching low pressure system, currently over Alabama, moving east. Both the ECMWF and the GFS have the upper level low digging to the southeast through tomorrow, trying to cutoff from the main flow.
/issued 521 AM CST Tue Feb 21 2017/ VFR with light winds as an upper level ridge axis moves overhead. /issued 323 AM CST Tue Feb 21 2017/ A warm and generally uneventful weather day is on tap today, as an upper level ridge axis just to our west moves over the Texas South Plains region later today, then shifts east tonight. Relatively mild will continue tonight, although we are siding with the lower end of guidance due to light wind and dry air. On Wednesday, a short wave trough will dig across the Sierra Nevada mountains.
1147 AM EST Tue Feb 21 2017 High pressure will crest over the region early today before shifting offshore. A warm front will push east through the region tonight. Low pressure moving east through southern Canada will drive a cold front toward the region late Wednesday and Wednesday night.
The weak cold front should clear the metro by 0z and forecast area by 6z. High pressure will build into the area slowly from the west.
350 PM CST Tue Feb 21 2017 Skies are mostly sunny to sunny across Southeast Texas this afternoon with high temperatures so far mainly in the lower to mid 70s. It will be clear and cool tonight and on the warm side tomorrow as weak high pressure builds into the area.
