331 AM CST Mon Jan 22 2018 (Today and Tonight) A cold front will move through West Central Texas this morning, resulting in northwest winds of 10 to 20 mph, with higher gusts. Slightly cooler temperatures are forecast today, with highs in the upper 50s to lower 60s. A cold front will move through the area this afternoon, resulting in northwest 20 foot winds increasing to 15 to 20 mph, with higher gusts.
A cold front in association with this low is located across western Arkansas down across the ArkLaTex region and into the Texas Hill Country. Highs today should reach into the the lower 60s in the Delta to the lower 70s in the Pine Belt. As the upper system starts to pull off to the east, high pressure at the surface will move in this evening.
Precipitation in the form of rain showers ahead of the cold front will develop by the early to mid-afternoon hours from west to east. Increased low- level flow surrounding the surface flow will also create gusty winds across the area in the wake of the passing cold front. Regardless, northwesterly flow and cold advection will bring a return of sub-freezing surface temperatures late this evening and overnight.
227 AM EST Mon Jan 22 2018 High pressure remains centered off the Mid Atlantic coast through today. A cold front crosses the region Tuesday morning and moves well off the coast by Tuesday night.
Much cooler temperatures continue, with a widespread freeze Monday morning. Dry conditions with warmer temperatures most of the week, before a trough brings cooler air and gusty winds late in the week. Warmer Monday with warming trend continuing into mid-week.
309 AM CST Mon Jan 22 2018 The upper level low over Kansas will slowly move off to the east today and upper level ridging will build in on Tuesday. Winds will drop off quickly after sunset as the upper low moves off to the east and will generally be light through Tuesday night.
221 AM EST Mon Jan 22 2018 High pressure remains centered off the Mid Atlantic coast through today. A cold front crosses the region Tuesday morning and moves well off the coast by Tuesday night.
Upper low currently over Kansas will push east into the Great Lakes region by Tuesday morning. Guidance continues to indicate a secondary band of convection developing closer to the upper low later this afternoon, but it should largely stay to our north. May see some wrap around showers on the backside of the low spread into our far northern counties during the evening/overnight hours.
As the upper low over central Kansas begins to pivot northeast guidance suggests this band should begin to weaken as precipitation begins to focus along stronger 850:750 frontal zone over NW Iowa.
1030 PM MST Sun Jan 21 2018 Water vapor shows upper low developing over sern CO, with surface analysis placing low center over western KS. Snowfall will continue to increase this afternoon and evening across south central SD, especially Mellette Todd and Tripp counties, with upper low deepening even further as it tracks east across KS.
334 AM CST Mon Jan 22 2018 A cold front pushed through the Panhandles yesterday evening, and northwest winds will prevail today behind that front. Winds will also make the temperatures feel cooler today. Temperatures on Tuesday will be similar, but will feel warmer as winds will likely be light and variable with mostly sunny skies.
An area of high pressure will move in for the middle part of the week leading to mostly dry weather. Models are in reasonable agreement in showing a deepening area of low pressure tracking northeastward through the Great Lakes Region Today and into Tonight. Will maintain the high pops and show a northeastward progression of the thunderstorm risk today. with the High Res Euro trying to lower surface temperatures below freezing in the afternoon.
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.
547 AM EST Tue Nov 28 2017 Dry high pressure will prevail through Wednesday.
319 AM PST Tue Nov 28 2017 Rain is starting to show up on the radar near Portland as a front and upper level low move through the region. This will result in a high probability of precipitation across southern Oregon and northern California, yet measurable precipitation will be on the lower side as the system is very progressive and will move through the area quickly. After this system moves through, high pressure should build rather quickly clearing out skies and bringing fog into the valleys.
High pressure is building in over central California behind the exiting frontal system. A dense fog advisory remains in effect for this area as there are indications that the fog could continue to thicken and spread given the recent rainfall and high pressure building overhead. The upper ridge will slide eastward as a weak trough drops into the region by Wednesday. Models have somewhat similar solutions in handling this passing trough, moving it through the region Wednesday and pinching off a low in the Pacific to the west of Baja.
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.
550 AM 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.
650 AM EST Tue Nov 28 2017 High pressure over the area tonight will move offshore Tuesday.
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.
513 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.
Temperatures will range from the low 70s near the coast to the mid/upper 70s well inland. North northeast winds 10 to 15 knots will become more east northeast this afternoon as inverted trough over the waters shifts west.
626 AM EST Tue Nov 28 2017 High pressure will bring fair skies and mild temperatures to NY and PA today. A weak cold front will move through tonight into early Wednesday. Mild temperatures will develop on the backside of a departing anticyclone today. A cold front well north into Ontario will skirt NY tonight, setting off a few light showers or sprinkles. Light showers and sprinkles will depart the northern forecast area early Wednesday as a cold front moves toward the Atlantic seaboard. High pressure, coincident with a ridge building aloft, will slide east through the Ohio Valley and toward Western NY and PA Wednesday afternoon.
Aloft - Broad troughing resides across the southeast U. A ridge initially from Mexico to the central Plains slides into the Gulf region as it flattens. in response to a short wave trough tracking from the 4-Corners region to the Mid- Mississippi Valley. Surface - High pressure sprawling across the eastern states. The high pressure to the north dominates with northeasterly to easterly flow which will slowly increase moisture somewhat across the area. Then the ridge aloft moving into the Gulf starts to nudge this moisture gradient southward Wed. Temperatures continue to run on the warm side of normal with highs Wed a degree or two above the highs today.
935 AM EST Tue Nov 28 2017 High pressure largely controls the area through Wednesday night, less a dry cold front Tuesday night/Wednesday.
Temperatures will rebound an average of 5 to 7 degrees over Mondays obs with highs expected to reach into the low to mid 60s by this afternoon. Slightly cooler conditions are forecast over elevated terrain with highs topping out in the low to mid 50s.
Not much to write home about today as aloft we'll be under mostly zonal flow as the upper ridge remains across central Mexico. Upstream, a low pressure system will be getting its act together across the TX high plains region. At that time, a cold frontal boundary will be moving southward into central TX and eventually our region.
926 AM EST Tue Nov 28 2017 A tandem of mid/upper level lows stretch from the central Gulf of Mexico to the northern Florida peninsula.
612 AM EST Tue Nov 28 2017 A cold front near the Mississippi river will push east across the region tonight.
Light south winds will increase and become northwesterly and northerly today behind a cold front moving through the area. /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.
1002 AM 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.
Then building high pressure will bring mostly dry conditions through the remainder of the work week before another frontal boundary impacts northwest California this weekend. High pressure will build in behind the exiting frontal boundary with some chilly temperatures expected once again tonight.
An upper level closed low is moving southeast through the Four Corners region. Temperatures will be cooler tonight/Wednesday morning behind the front with lows in the upper 30s to mid 40s. (Wednesday through next Tuesday) By Wednesday morning, an upper level trough will move east across Oklahoma. At the surface, a cold front will be moving east across the area during the morning hours.
Mild conditions expected today with an upper ridge sliding across the region. High pressure over the northern Rockies will also be spreading eastward, with downslope flow/chinook developing along the front range by late in the day. Upper trof pushes from the Pacific Northwest into Montana tonight bringing a cold front with it. Following the upper trof passage on Wednesday the remainder of the week will feature flat westerly flow.
Windy conditions continue early this morning across the region, with a tight pressure gradient in place ahead of an approaching cold front. Cooler temperatures will build into the area tonight, with lows falling into the mid to upper 20s under clearing skies.
551 AM CST Tue Nov 28 2017 Strong cold front was racing southward this morning through the northern Texas Panhandle, a little ahead of the latest short-term solutions. Well formed upper level low pressure system located near Cuba, New Mexico will continue east across the northern Texas Panhandle late afternoon and early this evening. Then, the cold front will speed through TAF sites mostly late this morning. Majority of expectations indicate surface wind speeds will mostly range in the lower 20s but strong pressure rises this morning could elevate speeds into the mid 20 knot range for a period, as well. 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.
An approaching upper-level low, along with a surface cold front and developing low on the front, will bring deteriorating weather to Oklahoma/north Texas later today. Its approach will coincide with the advance of a cold front across Oklahoma and north Texas, and the development of a surface wave/low on the front over Oklahoma.
604 AM EST Tue Nov 28 2017 High pressure largely controls the area through Wednesday night, less a dry cold front Tuesday night/Wednesday.
635 AM EST Tue Nov 28 2017 Unseasonably warm conditions will prevail through much of the day ahead of a cold front set to sweep through tonight. A low chance of rain showers will also accompany the cold front as it passes Tuesday afternoon and evening. Strong southwesterly flow helping keep temperatures quite balmy for late November with readings from the lower 40s NE to lower 50s NW. Cold front still well NW of the area, located from the arrowhead of Minnesota to NW Iowa. Another northern stream trough will move through the Great Lakes late in the weekend. Stronger trough will begin to dig into the central Plains with any possible impacts remaining outside the current forecast period. Gusty SW surface winds then expected ahead of approaching cold front.
539 AM CST Tue Nov 28 2017 Surface cold front extended from northwest Iowa through southeast Nebraska and north central Kansas at 200 AM. High pressure builds into the area behind the front today and tonight. By tonight, models develop a closed upper low over the southern plains which tracks east toward the Ohio Valley on Wednesday. This northern system will drag another cold front through the area by Wednesday evening.
The higher rainfall chances and amounts will reside north of I-40.
GAH PREVIOUS SHORT TERM DICUSSION: Mild conditions expected today with an upper ridge sliding across the region. High pressure over the northern Rockies will also be spreading eastward, with downslope flow/chinook developing along the front range by late in the day. Upper trof pushes from the Pacific Northwest into Montana tonight bringing a cold front with it. Following the upper trof passage on Wednesday the remainder of the week will feature flat westerly flow.
347 AM MST Tue Nov 28 2017 A cold front moved thru the southeast plains this morning and will continue bringing some gusty northerly winds thru much of the morning. An upper level low will move east- southeast over northern NM today and into the TX panhandle by late afternoon or early evening. There is also a chance that some light freezing pcpn could occur over portions of Teller and northern El Paso counties this morning, however with generally warm ground temps, it doesn't seem that it would affect the roads, but caution should be used if freezing pcpn does develop. Temps today will be much cooler than yesterday, and it generally looks like the southeast plains will see highs in the 40s, but some lower 50s are possible over the far east plains.
506 AM CST Tue Nov 28 2017 A ridge axis aloft extends from the southern plains northeastward into the OH valley eith a trough from the Rockies into the northern plains. At the surface, a fairly tight pressure gradient was located across the area ahead of a cold front which extended from southwest KS up towards the U. The cold front will move into the area today and we should have some better dewpoints along and ahead of the front (as evidenced by observations over eastern KS). Eastern Ozarks will have the lowest humidity levels during the afternoon (in the 20s), but surface winds will likely keep fire weather conditions in the elevated category.
627 AM CST Tue Nov 28 2017 So far the large stratus area associated with a cold front across Manitoba is trending to the east of the CWA. Wednesday: a quick moving surface front and proceeding warm front will push east across the state.
549 AM EST Tue Nov 28 2017 Departing high pressure will create a milder southwest flow and moderating temperatures today and tonight.
Expect lowest dewpoints across the higher elevations of the TN/NC mountains and northeast TN/southwest VA where afternoon minimum RH could be in the 20-30 percent range with isolated lower values across the higher elevations. Chattanooga Airport, TN 65 43 65 49 / 0 0 10 10 Knoxville McGhee Tyson Airport, TN 63 39 62 46 / 0 0 0 10 Oak Ridge, TN 64 40 63 46 / 0 0 0 10 Tri Cities Airport, TN 62 34 61 40 / 0 0 0 10.
522 AM CST Tue Nov 28 2017 The upper level trough that brought last night's cold front will continue pushing east.
425 AM MST Tue Nov 28 2017 A shallow layer of moisture was all that developed in the wake of last evening's cold frontal passage over northeast Colorado. Temperatures are expected to remain much cooler than yesterday's record setting numbers, with afternoon highs in the mid and upper 40s across the plains. Mostly clear skies are expected to continue tonight, allowing temperatures to drop back down to around the freezing mark.
434 AM MST Tue Nov 28 2017 Upper level flow will remain amplified, but progressive in the period, bringing mild weather with periodic ridge topping/flattening impulses in the flow. However, the main wind event will be with the cold front late Wed morning and afternoon across NW SD. Any snow will likely be confined to the higher elevations of the Black Hills. PAC westerly downslope flow will return Thur into the weekend with forecast models still supporting an amplifying ridge by the end of the weekend as a deep trough drops into the western CONUS.
922 AM EST Tue Nov 28 2017 A cold front near the Mississippi river will push east across the region tonight.
344 AM MST Tue Nov 28 2017 Broken clouds and some elevated winds have lingered across northwest Montana overnight, keeping temperatures slightly warmer than forecast so far this morning. In north-central Idaho valleys where overhead skies are clear, areas of fog/freezing fog have developed and could impact travelers (particularly along US-12) now through late morning.
740 AM EST Tue Nov 28 2017 Departing high pressure will create a milder southwest flow and moderating temperatures today and tonight.
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.
558 AM EST Tue Nov 28 2017 High pressure will dominate our weather pattern today through at least Wednesday night with dry weather and above normal temperatures.
915 AM EST Tue Nov 28 2017 High pressure will move offshore today.
615 AM EST Tue Nov 28 2017 High pressure moves off the coast today.
A mid and upper level low moving out of the southern Rockies into the southern Plains this afternoon through tonight will send a cold front south into Texas. The weak cold front will move into the Hill Country and Rio Grande after midnight and through the remainder of the CWA by daybreak Wednesday. Slightly cooler on Wednesday with highs in the upper 60s to mid 70s.
942 AM EST Tue Nov 28 2017 High pressure remains near the coast through tonight.
243 PM EDT Mon Oct 9 2017 High pressure will nose in from the Upper Great Lakes tonight.
Ahead of this potent wave an area of rain is impacting central and western Nebraska with strong to severe thunderstorms in southeast Kansas ahead of the cold front. Temperatures will continue to drop, but eventually where the cloud cover remains it'll stay warmer additionally while the northerly winds will decrease in speed, they will not be calm. There is a small portion of Sherman county that also has freezing temperatures, but with the lack of confidence have decided to not include them in the warning at this time. If the clearing line doesn't reach these counties, we very likely could not drop to freezing, while if it moves further, we could easily drop to freezing further east. Tuesday night: This period will have a much better chance for freezing temperatures.
An approaching cold front will be making its way through the northwestern CWA shortly after midnight tomorrow. A mostly overcast morning with scattered showers and thunderstorms in the vicinity of the lower level front as it encounters the higher pooling of downstream moisture over the southern half of the forecast area.
523 PM EDT Mon Oct 9 2017 Moisture with the remnants of Nate will continue to shift off to the east as high pressure builds overhead. This will be the big question overnight, will the dry air win out and slowly decay the low clouds, or with sunset, will lowest layers of the atmosphere resaturate in low clouds and fog. Tuesday should be mostly dry with high pressure in place but clouds will start to spread northward ahead of the next low pressure system, ejecting out of the midwest. This aforementioned low will track across northern Ohio, with the warm front providing for increased rain chances overnight Tuesday. It appears both downsloping southeasterly wind and a dry slot may be limiting factors for QPF outside of the initial warm front surge, but will still maintain likely PoPs, even with low QPF forecast.
A surge of southerly air will lead to the development of a warm front across the state by tomorrow afternoon, as analyzed by WPC, and also create enough instability that some isolated thunderstorms cannot be ruled out across the region.
Temperatures will run near normal through Tuesday, then trend several degrees cooler through the end of the week.
During the overnight periods, interior temperatures will cool into the lower to mid 30s for much of the region, warming to the 40s along the immediate coast.
WV shows the upper trough over SW CO/NW NM at 18, but the cold front ended up a little faster than previously advertised, and fropa'd KMAF right at 17Z, w/little fanfare other than establishing the high temp for the day. The cold front will slow due to diurnal heating this afternoon somewhere invof the Pecos River, then pick up speed after sunset. Model temp progs suggest nrn Lea will stay well-abv freezing, w/post-frontal winds to keep things mixed.
129 PM PDT Mon Oct 9 2017 A series of dry cold fronts will provide periods of gusty winds and cool downs this week. Temperatures will warm on Tuesday as gusty southwesterly winds develop ahead of an approaching cold front.
303 PM EDT Mon Oct 9 2017 A cold front will combine with moisture from the remnants of Nate to bring showers to the area into this evening.
Breezes are starting to freshen across the eastern portions of the service area as gradient flow increases along the southwestern flank of a building high pressure cell.
Temperatures will run near normal through Tuesday, then trend several degrees cooler through the end of the week. This is typically a warmer and drier pattern for this area. Temperatures will generally run near normal through Tuesday in the west to northwest flow between this exiting trough and another developing trough moving into the Pac NW.
Diurnal cumulus should diminish by early evening as well, nearby sagging cold front.
309 PM MDT Mon Oct 9 2017 Relatively warm and dry high pressure will be present over the Northern Rockies through midday Tuesday.
