This clearing along with relatively calm winds will result in another chilly night with lows in the low-mid 20s over central MN & west- central WI, & upper 20s across southern MN & the Twin Cities metro. Frontogenesis in the low-mid levels really begins to ramp up later in the afternoon & this along with some isentropic ascent along the frontal boundary will result in a swath of precip developing first over the Dakotas, & then spreading into western MN by mid- afternoon. This precipitation is expected to fall as snow as wet- bulb profiles remain below freezing, although approach 0C towards the surface.
357 PM EDT Thu Nov 2 2017 The center of high pressure will move into the northern Atlantic tonight, while a cold front pushes eastward through the Ohio Valley. The cold front will approach from the northwest Friday, then crosses the region Friday night.
332 PM EDT Thu Nov 2 2017 Damp and dreary conditions are expected to continue into the evening hours for most of the area as a cold front approaches from the northwest. Low overcast skies and light showers have limited temperatures this afternoon to the low-50s in the South Bend area. Meanwhile, the Fort Wayne area has seen several dry hours and temperatures in the low-60s. The approaching cold front will promote additional rain showers and perhaps a few storms through early tonight.
Winds in the Guadalupe Mountains have decreased below high wind criteria and are expected to continue to weaken so have cancelled the High Wind Warning. An upper trough digs south over the west coast on Friday. A cold front starts to move into the northeastern CWA tonight into Friday morning but winds will shift back around to the southwest Friday afternoon so temperatures will not be affected much on Friday except across the far northeast CWA.
313 PM CDT Thu Nov 2 2017 An upper level high pressure area over northern Mexico will keep a southwesterly flow pattern in the mid and upper levels over Southeast Texas through the weekend and very warm temperatures for this time of the year are expected.
Deterministic NAM/GFS/ECMWF consistent with a quasi-zonal upper pattern during the period, with a weak disturbance predicted to move across TX/SRN Plains Friday, yet with the bulk of associated forcing north of the CWA/MSA, and with a ridge building over the SCNTRL CONUS Friday night.
Areas north of the front were hovering in the lower 50s, while mid-upper 60s were common from about I-72 southward. Quiet weather is expected on Friday, as high pressure drifts east into the upper Great Lakes region. No significant push of cooler air is expected, as the upper flow amplifies a bit more out of the southwest.
At the surface, weak high pressure will dominate the local area. The latest ensemble guidance indicates the highest chances across the western portion of the area, but patchy fog could occur anywhere late tonight.
313 PM CDT Thu Nov 2 2017 Current visible satellite trends show the low clouds over parts of the area hanging tough through the daytime hours. The low clouds should fill back in for all areas later tonight as richer moist air to the east of Kansas spreads westward over-running the shallow cool airmass.
The leading edge of a cold front had progressed to Colby KS, through Aurora NE and Wayne NE. A cold front will have pushed through western Nebraska by 12z this morning. Cooler air drawn into the area today will limit highs to only the upper 30s northern Sheridan and nw Cherry county, while upper 40s should be reached portions of southwest into central Nebraska. A warm front aloft will move eastward tonight. While very little precipitation may occur (a trace to a few hundredths), precipitation type to range from mainly light rain chances Sheridan county, to freezing rain to snow chances central into eastern Cherry county, then snow chances eastward into Holt and Boyd county. A rise in temperatures is also expected for the first part of the weekend as south winds bring warmer air into the region.
Under partly cloudy skies with a moderate northeast breeze, temperatures along the island chain are in the lower 80s. Aside from a low amplitude mid to upper level trough which slides down the east coast of Florida late this weekend with little fanfare, the local area will remain influenced by a relatively deep ridge through that depth.
Upper trough moving through the Great Lakes this afternoon. At the surface, low pressure over eastern Lake Superior with a cold front through the middle of MI. Cold front will clear the late this evening.
423 PM EDT Thu Nov 2 2017 Low pressure developing west of the region will bring a cold front through the North Country on Friday with periods of rain expected Friday morning.
A positively tilted trough of low pressure over the Pac NW will basically remain in place the next few days, pulling in moist air off the Pacific into southern California.
Upper level flow is mostly zonal with a ridge to the south and a trough to the north. Temperatures will be above normal thanks to the low level warm advection with overnight lows in the mid 50s to low 60s and highs on Friday in the upper 60s to mid 70s.
/issued 304 AM CDT Thu Nov 2 2017/ Skies are cloudy across the forecast area early this morning with temperatures in the low to mid 60s.
A cold front will approach from the northwest late tonight before pushing south of the forecast area by the end of the period. Cold front pushes through on Friday then stalls just south of the CWA Friday night.
The jet will transition to the north as an upper trough pushes toward the west coast bringing increased SW flow over the Great Basin. Lows will get back into the lower 30s with clearing overnight creating some low stratus/fog formation in the early hours on Friday. Temperatures will be warmer than today with highs reaching into the mid 60s.
342 PM MDT Thu Nov 2 2017 A closed low over the Pacific northwest will slowly sag south through the short term period. The biggest impact will be increasing southwesterly winds, mainly north of Interstate-70 and across the higher terrain. A broad trough of low pressure over the northwestern states will eject several disturbances across the region through the period.
Main upper trof moving from the central plains to the eastern conus through Fri will continue to weaken with embedded mid level short waves still tracking eastward generally over central and lower parts of the country. Lows tonight will continue to run well above seasonal averages ranging from the lower 60s to the west, upper 50s to lower 60s to the east and the mid 60s near the immediate coast. Highs Fri will range from the lower 80s for most inland areas and the upper 70s near the coast.
Temps will only rise a few degrees during the day, with NE winds bringing cooler temps, but still above normal, on Friday night.
This afternoon's surface analysis shows an area of high pressure centered over the east coast and an area of low pressure extending from the Great Lakes to central Oklahoma. Southerly flow will continue to advect low level moisture in the region resulting in dewpoints remaining in the low to mid 70s.
The main upper trough continues to move eastward across the area this morning, and should lift off towards the Great Lakes by afternoon. Flow aloft starts to become more southwesterly, with low pressure developing over the Rockies.
In fact, temperatures should range from 5-10 degrees above seasonal average as an upper level high begins to build over Mexico/northern Gulf. Friday, as you can imagine with the high aloft building even closer to our area it will be just as warm (if not a touch warmer) and just as dry as Thursday, although, southeasterly flow is a bit more favorable for inland progression of the sea breeze.
Some instability will be present both today and tonight as a cold front slowly moves into southern Missouri. The previously mentioned cold front will stall over northern Arkansas Friday morning, and begin surging back northward by Friday afternoon.
A cold front will approach from the northwest late tonight before pushing south of the forecast area by the end of the period.
131 PM EDT Thu Nov 2 2017 Periodic shower chances are expected over the next several days as a cold front crosses early tomorrow morning.
136 PM CDT Thu Nov 2 2017 The cold front is bisecting MO/IL as we are in the warm sector, with sfc dew point tongue of upper 60s extending across heart of FA.
337 PM CDT Thu Nov 2 2017 At 3 PM, the cold front which moved through the region this morning was located over Lower Michigan and northwest Indiana. 00z models continue to show that high pressure will build across the region. This along with light boundary winds in central Wisconsin would allow temperatures to cool into the lower 20s. On Friday, the clouds will rapidly increase ahead of an approaching warm front. 00z models continue to show that a warm front will move north through the region. The highest liquid amount in this band ranges from two tenths to a third of an inch.
A cold front will then cross the region Friday with a few showers, followed by cooler air.
545 PM EDT Thu Nov 2 2017 Periodic shower chances are expected over the next several days as a cold front crosses early tomorrow morning.
Current surface analysis reveals a warm front across northern Indiana and Ohio. Surface flow behind the warm front has remained out of the south and has been gusty at times, with some stations reporting +20mph winds. The warm front over northern Indiana/Ohio will transition into a stationary front near the Great Lakes area today, leaving our region well within the warm sector. Despite the widespread cloud cover, temperatures will be quite warm for November, as many places reach the low 70s this afternoon. With the warm front well north of the area, relatively dry air from 850mb on up (resulting in limited moisture depth), and no evidence of large scale forcing or lift, expect most areas to remain dry today minus a few sprinkles. The stationary front begins to shift back to the region as a cold front tonight.
A mostly zonal flow pattern exists across much of the CONUS this afternoon with broad upper ridging building in across the Caribbean and Gulf of Mexico. With high pressure in control from the surface to the upper troposphere, a dry and stable weather pattern will persist. A weak inverted trough will gradually move westward over the Bahamas on Friday. Otherwise, expect highs to remain near or just a couple of degrees above normal in the lower to mid 80s, and lows ranging from the upper 50s north to the low to mid 60s south.
Tonight Light precip is moving out as weak low pressure exits the area and ridging moves in from the west. Friday through next Thursday High pressure will keep the weather dry during the day on Friday and Friday evening.
Fog is expected to lift/dissipate by mid Friday morning, but a good amount of low level cloudiness is forecast to prevail ahead of a passing short wave disturbance and a weak cold front over central Texas. High temperatures should be few degrees cooler than today's highs due to cloud coverage.
At the sfc, an area of low pressure is deepening across NErn OK, with a cold front sprawled W/SW of this feature across portions of the Panhandle Regions of TX/OK. Aside from the potential for convection through sunrise Friday morning, an abundance of moisture trapped in the lowest levels of the atmosphere will set the stage for lingering low clouds and reduced visibilities overnight. More widespread/slightly more dense fog is expected in the Srn zones where convection hasn't really overturned the lower/moist levels of the atmosphere, so expect lower ceilings/more reduced vsbys there (though this should stay above Dense Fog Criteria attm).
1214 PM CDT Thu Nov 2 2017 /18Z TAFS/ A weak cold front will move into the Big Country this evening, approaching KABI around 04z. The combination of a low level thermal ridge, a dryline located just east of our area, and gusty west to southwest winds will result in record heat and drying in the boundary layer. Low tonight will range from the lower 50s across the northern Big Country to the lower 60s over the far southeast part of the area.
205 PM CDT Thu Nov 2 2017 A very warm day was occuring across the area ahead of a cold front that as of 200PM stretches from Sedaila, MO to Parsons, KS. Record breaking temps are occuring with highs in the lower 80s occuring at a few locations. Temps will be much cooler tomorrow given the clouds and east/northeast winds.
249 PM CDT Thu Nov 2 2017 A cold frontal boundary which crossed the central plains overnight had pushed south into the southern plains this afternoon. Models are hitting harder the low cloud heights vs low visibility potential in fog, but would not be surprised to see a few areas with low visibilities and subsequently fog remains in the forecast. On Friday, cloud cover is expected to become widespread across our region with the lowest cloud heights across our western and southern zones. The cloud cover keep temperatures chilly and have went with the cool side of guidance for highs in the low to mid 40s. Current models keep temperatures above freezing Friday night so precipitation is expected to fall as drizzle vs freezing drizzle which we have to monitor closely this time of year.
552 PM EDT Thu Nov 2 2017 Low pressure developing west of the region will bring a cold front through the North Country on Friday with periods of rain expected Friday morning.
Temperature trends were much cooler today with the stratus in place and so have adjusted temps for tonight in a similar fashion. Enhanced isentropic lift noted within the low levels suggest light drizzle to once again spread over the southern half of the area during the morning and afternoon Friday.
325 PM EDT Thu Nov 2 2017 A cold front will push southeast through the region on Friday.
1237 PM CDT Thu Nov 2 2017 In the near-term, dense fog, drizzle, and stratus will be the main concerns as an inverted trough axis/stationary boundary sets up across the CWA. While the lowest ceilings and visibilities have pulled a county or two north in the last few hours, a very gradual southward drift of the front will allow fog to redevelop in areas that have recently cleared, so have opted to continue the dense fog advisory as a near-term forecast vs. Once the boundary pushes south, rain chances will diminish and slightly cooler temperatures will build in for the overnight period.
Current surface analysis shows cold front south and west of the forecast area, with northerly winds across the area. Upper level analysis shows broad trough across the region, with strong westerly jet from the Pacific NW to the Great Lakes region. Flow aloft will turn more southwesterly tonight into the early part of the weekend as trough digs southeastward across the western US.
346 PM CDT Thu Nov 2 2017 A large area of high pressure filtering down from Canada and into the northern plains, will move eastward tonight toward the MS Valley. Surface winds will shift to an easterly direction bringing in dry air in the lowest 2km. This is a key factor with the warm air advection/warm front, lifting northeastward late tonight and Friday. Despite the upper ridge passing eastward allowing strong 850-700mb thetae advection to take over, the dry low layers will really keep accumulating rain or snowfall at bay. However as the aforementioned warm front lifts northward, the mid levels dry out.
Weak cold front will cause surface winds to trend from west to north and then northeast, with occasional gusts in the 25 to 30 kt range this morning and early afternoon. For today, a cold front will move across the fcst area. Latest model guidance has come in cooler overall, especially northern half of the region and have followed suit in the grids.
335 PM EDT Thu Nov 2 2017 The center of high pressure will move into the northern Atlantic tonight, while a cold front pushes eastward through the Ohio Valley. The cold front will approach from the northwest Friday, then crosses the region Friday night.
103 PM EDT Thu Nov 2 2017 Hydro A wave on the frontal system moving through the area this evening will bring the risk of thunderstorms near I-94, east of Battle Creek, otherwise any lingering shower activity should come to an end by midnight as cooler and drier air move in behind the frontal system.
638 PM EDT Thu Nov 2 2017 A cold front will push southeast through the region on Friday.
Ahead of a cold front this afternoon, record to near record temperatures will occur across southern Oklahoma and western north Texas. The cold front will stall across northern and central Texas on Friday as lee trough develops over the High Plains.
A weak inverted trough located off the Florida Atlantic coast may lead to a few showers over mainly eastern Florida, with a few sprinkles possible over interior parts of the peninsula, but most areas will remain dry. High pressure will remain situated from the southeastern U. An inverted trough approaching Florida from the east this weekend will turn winds to a more northerly direction, but winds and seas should remain below headline criteria.
A cold front has pushed into the area today which has held temperatures to the mid 50s across the Oklahoma Panhandles while temperatures have reached into the upper 70s across the southern Texas Panhandle. The cooler post-frontal airmass combined with light winds overnight are expected to result in low clouds and patchy fog across the area.
1202 PM EST Sat Jan 27 2018 High pressure will continue shifting eastward today. A cold front will spread rain across the area tonight through Sunday night.
Upper level trough axis remains to our west this afternoon but much drier aloft building into our region from the west and southwest in the wake of the disturbance to our southeast. Tricky temperature forecast for tonight as the low cloud cover will be slow to clear from northwest to southeast tonight. Where clouds clear we should see temperatures fall quickly overnight with much drier dewpoints noted in the wake of the cold front across the Middle Red River Valley of Eastern and SOuthern Oklahoma into North Central Texas with this drier air expected to slowly spill into our northwest zones. Any remaining cloud cover should push south and east of our region Sunday Morning with a nice warmup expected areawide with really not much cold air in the wake of this current cold front.
Band of rain associated with a cold front currently crossing the TN river. and into early Sunday on the plateau as the trailing cold front pushes slowly across.
A secondary weak wave and associated cold front will continue to move southeast across the area this evening into the overnight hours. Arctic high pressure builds in across the International Border and North Dakota on Sunday, leaving the area under a cold northerly flow; cooling down temperatures to below normal.
255 PM EST Sat Jan 27 2018 Rain will taper off this evening as a cold front moves through the area and weak high pressure begins to build in from the west.
The base of the broad mid-level trough axis that is centered over the Great Lakes region will keep westerly flow in place over the region today. Do not expect much in the way of CAA from this westerly flow, so with mostly sunny skies present the high temperatures should reach into the 50s. The combination of increased cloud cover and a shift to northerly winds from the frontal passage will result in cooler temperatures with highs ranging from the upper 30s to low 50s from north to south across the CWA. Canadian high pressure will slide southward into the central U.
The cold front has pushed through the majority of South Central Texas. What that means is that the upper level trof axis will very slowly push through South Central Texas. So it will take a while for the low clouds to scour out, probably not until Sunday late morning or early afternoon.
Temperatures reached the high 70s with dew points remaining in the low 60s. But winds should slowly drop down a few knots tonight and on Sunday as the high moves away even more and a ridge sets over the eastern Gulf of Mexico.
A cold front is currently situated west of the Ohio River, and is expected to traipse across Middle Tennessee during the evening and overnight.
A cold front is close to moving across the Mississippi River with a large area of rain moving east just ahead of the front. On Sunday night, a secondary cold front will move through the region.
Cold front currently stretches from western Great Lakes into west TX. Brief/weak upper ridging will pass over the Rockies and into the Plains Mon night into Tue. This will result in deepening lee troughing Tue and gusty south winds Tue afternoon. A series of impulses are expected to follow the initial wave, which will carve out a deep broad upper trough from the Rockies into the Ohio Valley. There is some model agreement in snow chances Thu across the high Plains with some of this possibly making it into our forecast area. These LLWS conditions are expected to abate a few hours after sunrise but the low levels will remain turbulent until a few hours after the front passes around noon Sunday.
High pressure over the western states will result in dry weather and warmer temperatures for much of the coming week.
On Sunday, winds will relax, as the 500mb trough continues to shift eastward, with weak high pressure spread from the Ozark Plateau southwestward towards the Permian Basin.
and Sunday Gusty west winds are expected today in the wake of a departing cold front. A secondary cold front will move through during the daytime hours, however NWP models indicate most of the snow associated with this front will be post-frontal with the bulk falling later this afternoon and into the evening hours. Lows tonight behind the secondary cold front are expected to be around 10 degrees across the north, with lows around 20 across east-central Wisconsin. Although high pressure builds in across the northern Plains on Sunday, trying to edge a ridge in across the area, clouds and snow/flurries will persist across much of the area as the area remains under an upper level trof. Highs Sunday will be cooler, ranging from around 20 across the north, with middle to upper 20s across the south.
A cold front will move through Western Washington this morning and will be followed by a weakening low pressure system that will move across northern portions of the area midday. The low will give breezy to windy conditions to the area today. A warm front will lift north through the area tonight and early Sunday then stall over southern British Columbia later Sunday and Sunday night.
1201 PM CST Sat Jan 27 2018 /18Z TAFS/ The cold front has pushed across West Central Texas late this morning with all terminals reporting northerly winds of 10 to 15 knots. /issued 547 AM CST Sat Jan 27 2018/ /12Z TAFS/ As of 5 AM, a cold front was passing through the KSJT terminal and will clear the far southern terminals by mid morning. /issued 328 AM CST Sat Jan 27 2018/ (Today and Tonight) A cold front is moving south across the Big Country early this morning and will clear far southern counties around the mid morning hours. For tonight, a drier airmass coupled with clear skies and light winds will allow temperatures to fall into the lower and middle 30s by daybreak Sunday.
Mild though slightly cooler feeling day than one might expect given plenty of sunshine. West/northwest breeze over lingering snow cover has brought the cooler feel to areas near the snowpack. The main story through Sunday is a cold front dropping south tonight, and then a weak mid-level wave passing by during the day Sunday.
302 PM EST Sat Jan 27 2018 Showers continue to spread through northwest Pennsylvania as a cold front will slide through the area tonight into early Sunday.
241 PM MST Sat Jan 27 2018 Latest satellite imagery shows northwest upper level flow over the west half of the CONUS with an upper level short wave trough moving southeast over the Northern Plains. Along and behind the trough cloud cover was spreading southeast across the CONUS. Lows will be slightly warmer than last night due to the cloud cover. Sunday morning the cold front will move through in the morning.
