/issued 840 AM EST Tue Nov 28 2017/ High pressure along the eastern seaboard will maintain a northeast to easterly wind flow over the region the rest of today. This increase in moisture along with some additional mid level moisture advecting into the region from the south associated with a weak upper level low over the southeast Gulf will support an increase in clouds across the region during the afternoon especially across central and southern areas along with perhaps some isolated low topped showers over central interior and southern counties as well, otherwise dry and warm conditions will prevail with temperatures climbing into the upper 70s to lower 80s.
1041 AM CST Tue Nov 28 2017 The approaching cold front is approximately from the NW corner of Illinois to Kansas City as of 10 a. A cold front currently stretching from Minnesota to northern Kansas will push into the area late this afternoon, but its arrival appears to be slightly slower than previously thought. with cooler readings near 60 degrees across the far northwest around Galesburg and Lacon. to the lower 40s south of I-70 where clouds will linger through the entire night.
A cold front continues to make its way across west central OK this afternoon.
206 PM EST Tue Nov 28 2017 High pressure will dominate our weather pattern tonight through at least Wednesday night with dry weather and above normal temperatures.
234 PM CST Tue Nov 28 2017 A surface cold front will slide southeast through the Missouri Ozarks into this evening. Meanwhile, a closed upper level low will move east across northern Oklahoma this evening and reach the Tulsa area by about 12 UTC. While low and mid-level moisture quality is not great, there will be quite a bit of lift associated with this low pressure system. After the balmy temperatures of the last few days, cooler temperatures are on tap for Wednesday with highs expected to be in the upper 50s to perhaps lower 60s.
420 PM EST Tue Nov 28 2017 At the surface, WPC analysis shows a prominent 1031 mb high over New England with a cold front draped southward from the midwest to Texas.
Forecast focus today will be temperatures trends as a cold front slides through the area during the morning hours. Cooler drier air begins to work into the northwest half of Wisconsin later in the afternoon but clouds decreasing as well. Further south along the cold front, mid level clouds were sparse over Minnesota and far northwest Wisconsin.
459 PM EST Tue Nov 28 2017 A warm front will cross the region overnight. A cold front will approach late tonight then cross the region Wednesday.
The chance for rain looks good for tonight across northeast Oklahoma, with the favorable upper low track. The highest chance will be after midnight, mainly north of Interstate 40.
Shower activity will decrease on Wednesday as upper low over n Fl shifts eastward and drier air settles over the area.
335 PM EST Tue Nov 28 2017 High pressure will bring fair skies and mild temperatures to NY and PA through this evening. A weak cold front will move through tonight into early Wednesday bringing more clouds and a few light rain or snow showers to Central NY. High pressure returns Wednesday night for clearing skies and cold temperatures. A weak cold front will move across the forecast area after midnight tonight. Temperatures are forecast to peak in the lower to mid- 40s during the late morning hours or midday before gradually falling back into the 30s by afternoon. especially in CNY and the higher terrain of NE PA. A ridge of high pressure aloft and at the surface builds over the area for clear skies, lighter winds and rather cold temperatures.
122 PM EST Tue Nov 28 2017 A weak and moisture starved cold front will drop through the area this evening with nothing more than a brief increase in cloud cover.
316 PM CST Tue Nov 28 2017 A cold front is slowly edging southeastward toward the central IL forecast area with cloud cover along and ahead of the front spreading into central IL as far east as about Taylorville to Champaign, and temperatures are peaking out or cooling slightly as a result. Dewpoints have reached the lower 40s under the cloud band which will be probably just a bit low for sprinkles which have been in the forecast from around I-72 northward, so have trimmed back wording to slight chance sprinkles and also trimmed back coverage as well.
A remnant of this morning's cold front is the wind we are feeling this afternoon due to the strong pressure gradient. Clouds are building due to isentropic ascent toward the Colorado/Kansas border this afternoon, and will track east with the low. Have left Comanche, Barber and Pratt counties with the highest POPs late this afternoon as they have the best chance for any accumulating rain. With clear skies behind the low, temperatures tonight will drop below freezing for most of Southwest Kansas. Tomorrow, as high pressure moves southeast, WAA advection returns by the end of the day, keeping highs closer to normal for this time of year, in the 50s. As one upper level trough moves across the Mid Mississippi Valley mid week another upper level trough will move from the Pacific Northwest to the Northern/Central Rockies.
333 PM CST Tue Nov 28 2017 The cold front has cleared the forecast area as of 3 pm with brisk north wind continuing late this afternoon.
1216 PM EST Tue Nov 28 2017 High pressure will move offshore today.
300 PM CST Tue Nov 28 2017 Mature cyclone over the Hudson Bay with cold front through the Great Lakes into an upper closed low over the Texas Panhandle. Some high clouds filtering in from the west through the day on Wednesday as the upper trough over the Pacific Northwest moves into the western plains of Canada and brings a cold front through the northern high plains late Wednesday afternoon through the evening. Strong southwesterly flow over the north through the day Highs on Wednesday still well above the low 40s average for highs with highs in the mid 50s.
Temperatures are in the upper 70s to near 80, and dew points are in the low to mid 70s. A non-tropical low pressure system is located in the Gulf of Mexico, and a trough of low pressure is stretched across the Florida Peninsula. An expansive high pressure ridge is anchored off the New England coast. The low pressure trough will lift northward across the Florida Peninsula tonight as the low pressure center in the gulf drifts eastward, weakening and emerging in the western Atlantic Wednesday. Highs tomorrow are expected to be in the low 80s, which is also slightly higher than climatological normals.
141 PM MST Tue Nov 28 2017 Cooler temperatures continue into tonight and Wednesday. The small cut off upper low moves through Oklahoma and weakens into an open wave as it moves through the plains while the next upper trough moves through the Pacific Northwest and emerges over the northern High Plains Wednesday afternoon. High pressure at the surface moves across the forecast area ahead of the next lee trough deepening along the Front Range in unison with the next upper trough moving east of the Rockies on Wednesday. Conditions will remain dry with some of the cooler temperatures over the western sections of the forecast area moderating slightly on Wednesday. Southwest to southwest near surface winds on the east side of the deepening lee trough will allow warm air advection and possible some downslope warming over the western sections.
the cold front extended from west central Kansas through central Iowa. As an upper trough moves into the Western Great Lakes, 850mb temperatures will be much cooler across the area today, ranging from 1 to 3C. Much cooler highs today, compared to yesterday's record breaking highs, ranging from the upper 40s northwest Sandhills to the lower 50s southeast. The upper flow will remain fairly zonal, as an upper trough crosses the Northern Rockies. Kept lows near previous forecast in the low to mid 20s. Ahead of the front a windy and mild day (highs in the mid 50s) are expected Wednesday, as a tight surface pressure gradient develops just ahead of the cold front.
1122 AM CST Tue Nov 28 2017 As of 17Z cold front had made it through all terminals with winds shifting to the north. A compact upper low will move from the four-corners to the Texas Panhandle by this afternoon. This will bring strong winds to the region behind a cold front although slightly later than previously forecast.
305 PM EST Tue Nov 28 2017 Moisture starved cold front tonight.
1240 PM EST Tue Nov 28 2017 A cold front near the Mississippi river will push east across the region tonight.
Temperatures overnight to fall into the low to mid 50s areawide. Temperatures on Wednesday to climb into the lower 70s.
340 PM CST Tue Nov 28 2017 A cold front will move across the area this afternoon and early this evening. However as the front moves south, it will stall a bit over northern Arkansas/western Kentucky/Tennessee as an upper level low pressure system moved into southeast Kansas/northeast Oklahoma Wednesday morning.
224 PM EST Tue Nov 28 2017 High pressure centered offshore will extend west over the area tonight into Wednesday.
1137 AM CST Tue Nov 28 2017 The approaching cold front is approximately from the NW corner of Illinois to Kansas City as of 10 a. A cold front currently stretching from Minnesota to northern Kansas will push into the area late this afternoon, but its arrival appears to be slightly slower than previously thought. with cooler readings near 60 degrees across the far northwest around Galesburg and Lacon. to the lower 40s south of I-70 where clouds will linger through the entire night.
348 PM EST Tue Nov 28 2017 A cold front located near Lake Michigan late this afternoon will move across the region tonight.
but will further lower later tonight as cooler air shifts over the region. The challenge could be in the lower valleys of western Montana from the Mission Valley southward to Missoula and Hamilton on whether snow showers may be intense enough to produce some sticking snow on roads towards the Wednesday morning commute time.
1230 PM EST Tue Nov 28 2017 High pressure centered to the east will keep dry weather and above normal temperatures over the Ohio Valley today. Dry weather will continue tonight through Wednesday as a weak cold front washes out across the Great Lakes.
However, the High Surf Advisory was pushed up a few hours earlier to account for the increased threat of sneaker waves as long period swell arrives today. A cold front will bring rain to the coast this morning with mainly MVFR and areas of mountain obscuration. Freezing levels now near 7000 ft msl will fall to around 5500 ft msl today and 3000 ft msl early Wednesday.
1211 PM EST Tue Nov 28 2017 VFR conditions continue with high pressure in control.
An upper level trough will move onshore tonight and spread showers into mainly the northern half of the CWA overnight. Next Pacific upper trough along 130W at 2 AM MST, moving steadily east. Trough axis will be along the Oregon coast around noon PST, eastern Oregon this evening, western Idaho late tonight, and western Montana 12Z Wednesday. Associated surface cold front will bring rain and snow showers to eastern Oregon this afternoon and evening, and western Idaho tonight, clearing from the west by sunrise Wednesday.
248 PM CST Tue Nov 28 2017 (Tonight and Wednesday) Cold front, just north of Midland and Aspermont to Benjamin line at 2 PM, will move rapidly southeast through West Central Texas this evening. Cold front should be along a Sterling City. Lows will be mainly in the lower 40s, with some mid and upper 30s in portions of the western Big Country and Concho Valley. It will be cooler Wednesday.
Upper level trough will continue to slowly slide eastward today. The main impacts from the pattern today will be an increase in clouds today and high temperatures (mid 70s) around 5 degrees warmer than yesterday.
238 PM CST Tue Nov 28 2017 High pressure continues to dominate the area, with warmer than average temperatures and dry conditions.
With surface ridging to the east, weak WSW flow aloft, and very dry air remaining through the air column with a clear sky, expect efficient radiational cooling with coldest temperatures in protected valleys. Closed low across the Southern Plains will become an open wave trough and progress eastward tomorrow, but 850-700 mb winds remain out of the WSW/W ahead of the disturbance with continued dry air evident through the mid to upper levels in forecast soundings. With surface ridging to our east and similar 850 mb temperatures, expect surface temperatures to remain above average and be within a degree or two of Tuesday afternoon observations.
343 PM CST Tue Nov 28 2017 Had to issue a Red Flag warning earlier this afternoon to account for the low humidity and strong winds across the eastern CWA. As has been the story for quite some time, sided with the higher end of guidance in regards to temperatures.
In addition, a weak cold front sliding in from the northwest coincident with the happenings aloft will be another factor to subtly increase lift further below 10 kft or so.
359 PM EST Tue Nov 28 2017 The latest surface map features retreating high pressure off of the Eastern Seaboard. A weak cold front extends from the Great Lakes down across the southern Plains, with another area of high pressure building in from the Rockies. Aloft, broad ridging is found in the East, with a pair of short wave troughs rotating through more the middle of the CONUS. Skies will remain clear initially tonight, before a weak cold front approaches from the northwest towards dawn, allowing for an increase in cloud cover. Expect the eastern sites to dip into the lower 30s, with mid to upper 30s in the broader valleys. Lows along the ridges will generally be in the mid 40s. The cold front will essentially dissolve as it drops down across our region on Wednesday.
Temperatures will warm quite a bit this afternoon ahead of an approaching cold front. Fire weather conditions will improve this evening as RHs increase behind the cold front. Gusty west winds this afternoon will gradually shift the NW then N by this evening with the arrival of a cold front. /issued 349 AM CST Tue Nov 28 2017/ An upper level trough is over northern New Mexico with southwest flow over the CWA. This upper trough will move over the Texas Panhandle by this evening, and a cold front will push into the area beginning this afternoon. Overnight lows tonight will be much cooler with temperatures in the 30s and 40s across the area.
With high pressure to the east, a gradual increase in surface based moisture favors the potential of developing late night fog. Upper level low spinning over north Florida early this morning will drift east through tonight and be located just off the NE Florida coast to the east of Jacksonville by late tonight. As this low drifts east, upper level ridging will increase over our area in the near term. At the surface, high pressure will continue to ridge into the area from the northeast.
Latest visible satellite shows a band of low clouds developing ahead of a cold front and associated wind shift. The chance for rain looks good for tonight across northeast Oklahoma, with the favorable upper low track. The highest chance will be after midnight, mainly north of Interstate 40.
239 PM MST Tue Nov 28 2017 Afternoon GOES-R water vapor image loop showed split flow aloft with a mid/upper level low tracking east from northeast NM into western TX panhandle/far southwest KS.
1142 AM CST Tue Nov 28 2017 Satellite and surface observations indicate a cold frontal boundary that stretches from Omaha down into SE Kansas currently. Warmer air will still reside on the southern side of this boundary creating a decent thermal gradient that runs SW to NE over the CWA this afternoon. The northern side of the boundary will be much cooler than yesterday with highs in the mid to upper 50s and south of the boundary in the low to mid 60s. A closed upper level low over OK will push just to the south of the CWA creating increased chances of light rain over our southern CWA Wednesday morning into the afternoon, but once again little to no accumulation is expected.
322 PM CST Tue Nov 28 2017 The cold front is currently from near Stillwater to Oklahoma City to Lawton to Seymour and is moving southeast through the area.
346 PM EST Tue Nov 28 2017 Dry high pressure will prevail through Wednesday.
1237 PM EST Tue Nov 28 2017 High pressure remains near the coast through tonight.
Rodriguez 234 AM CST High pressure expected to be in place at the start of the period, but quickly shift to the east.
/issued 241 AM CST Tue Nov 28 2017/ High pressure will continue to shift east today allowing southerly winds to bring in warmer temperatures to the Mid-South. Take caution when doing any outdoor burning Clouds ahead of an approaching upper level low pressure system will begin to spread into the area by sunrise Wednesday.
347 PM EST Tue Nov 28 2017 Warm breezy conditions will continue overnight ahead of an approaching cold front which will bring scattered light rain and snow showers to the area on Wednesday. Temperatures will fall sharply Wed evening behind the departing cold front and bottom out in the teens. Region is currently under strong southerly flow ahead of an approaching cold front. Most of our overnight hours will be dry ahead of approaching cold front, but may see some light rain showers start to make it into the Saint Lawrence valley towards the very early morning hours. Cold front finally crosses our area on Wednesday and we will have scattered light rain and snow showers with the frontal passage.
NW flow aloft is not the best for lee troughing and s-se winds will mostly be less than 10kts thru Tue. Minor mid level troughing is evident at 5h on Wed and moreso on Thur when GFS latches onto mid level mstr. Said trough will have passed e on Fri, but broad cyclonic flow will develop across wrn half of CONUS with a 110kt jet 3h serving to sharpen a mid/upper level trof by Sat AM. Trough and assocd cold front will be favored to pass thru CWFA late Sat night or early Sun AM. There is a degree uncertainty with this forecast as models close off an upper low across central TX or farther e on Sun/Mon.
330 AM CDT Mon Oct 16 2017 High pressure centered over northern Texas will move northeast across the Mississippi Valley into the Mid Atlantic Region by early Tuesday morning. The high will bring our area tranquil weather and temperatures near seasonal normals in the mid 60s today. Should see temperatures a few degrees warmer in the mid 40s over northern portions of the forecast area tonight as light southerly flow develops northwest of the ridge axis. Temperatures will be cooler in the upper 30s to around 40 under the ridge axis across southeast Missouri.
The surface cold front has moved east of the area, although some precip will linger behind it until the midlevel trough axis moves through around 12Z. High pressure will settle across KY/WV tonight, allowing winds to go calm across the northern half. Temps in that area will drop into the upper 30s, with some mid 30s in the higher elevations of SW VA and TN mountains.
623 AM EDT Mon Oct 16 2017 A cold front will slide offshore early this morning. Canadian high pressure with cooler and dry weather follows for later today into Tuesday. A large ridge of high pressure will build across the eastern U.
/issued 128 PM CDT Sun Oct 15 2017/ Looks like a quiet work week with moderating temperatures to near or slightly above normal high temperatures by Tuesday as an upper level ridge builds across the southwestern United States.
High pressure will persist across the region through the middle of the week allowing for continued very warm and dry conditions. Somewhat cooler weather with more cloud cover will arrive during the end of the week. Strong high pressure aloft will continue on Monday with 500mb heights to run around 591dm over the southern deserts; Monday will likely be the warmest day of the weak as the hottest locales reach to about 100 degrees.
347 AM CDT Mon Oct 16 2017 (Today and Tonight) A cold start to the morning is expected across West Central Texas, with most locations in the low to mid 40s. Plentiful sunshine today will allow temperatures to top out in the low to mid 70s this afternoon. Overnight low temperatures will drop into the low to mid 40s, with some low lying areas dropping into the upper 30s.
High pressure is forecast to remain stretched from Texas, across the Hoosier State, to New England. There is good model agreement today will be dry as high pressure moves in.
Dry cool advection will continue overnight in the wake of the cold frontal passage. Cold front has pushed through the area as well as the coastal waters. Frontal boundary is through South Texas but the arrival of the cooler air is lagging a little bit.
310 AM EDT Mon Oct 16 2017 A cold front will slide offshore early this morning. Canadian high pressure with cooler and dry weather follows for later today into Tuesday. A large ridge of high pressure will build across the eastern U.
Temperatures will rebound to near normal on Tuesday, then continue to gradually rise to well above normal right into this upcoming weekend, as a large area of high pressure builds in. Low clouds percolating off the lower lakes no expanding farther into C PA.
A weak pressure gradient with winds and seas generally low will continue through Monday, then an approaching cold front is expected to arrive over the eastern Gulf of Mexico Monday Night and Tuesday.
619 AM EDT Mon Oct 16 2017 A large area of high pressure will settle into the Ohio Valley for the upcoming week, with dry conditions expected. Conditions appear dry, clear, and slightly warmer than Monday -- lower to middle 60s.
134 AM EDT Mon Oct 16 2017 A cold front will cross the area Monday bringing chances of showers and isolated thunderstorms to the area. Behind the cold front high pressure will usher in much cooler and drier air through the end of the week. One more mild night on tap ahead of an approaching cold front. The main cold front is now moving into the central Appalachians, and into northwestern GA. The strong cold front will move through the region Monday, bringing rain to the area. Behind the front, high pressure will build into the forecast area along with much cooler and drier air. High pressure will continue building into the region Tuesday and Tuesday night with northeasterly winds continuing to usher cooler and drier air into the forecast area.
141 AM EDT Mon Oct 16 2017 High pressure will build into southern Ohio by Monday afternoon. The high will then persist through the remainder of the week. We will need to get a 5H trough east of the region to stop any of the lake effect showers that can develop across NE OH/NW PA late tonight into Monday morning. This trough looks like it will be east of the region by mid afternoon on Monday. High pressure will then increase its influence through Monday night. It will feel much cooler tonight into Monday.
Models suggest that a slowly progressive pattern will prevail with the ern mid/upper level trough giving way to ridging by the end of week over the ern CONUS and trough over the west. The trough will approach by the weekend, bringing pcpn chances back into the region.
421 AM CDT Mon Oct 16 2017 Today and Tonight: Early morning surface analysis had a 1030mb high centered over Oklahoma and the cold front southeast of our CWA. Much cooler and dry weather is expected through tonight. Afternoon highs today will top out cooler than normal, in the lower 70s. Normal lows run in the lower 50s.
505 AM EDT Mon Oct 16 2017 High pressure will build across the region from the west today through Tuesday. The cold front will reach the coast towards 8 to 9 am. The strongest winds with the LLJ have moved east, but there will still be sufficient winds aloft to mix down 30 to 40 mph gusts as the cold front crosses. There is strong cold air advection behind this front with dew points decreasing from the low 60s to the low to mid 20s by later tonight.
Areas near the lakeshore will be slightly warmer, with lows in the mid to upper 40's.
