115 PM EST Thu Nov 9 2017 High pressure should maintain dry weather today. A strong cold front will increase precipitation tonight and Friday and bring well below average temperatures into the weekend. Still think that any light showers will remain to the south and east, but will watch to make sure east-facing ridges don't get wet. Higher clouds are in place across the north in advance of the cold front arriving tonight. A strong cold front that will quickly cross this evening. Further south, more scattered activity is expected, even along the ridges where moisture remains limited. A dry Friday night follows as high pressure builds in from the northwest.
Expecting mostly sunny skies for the mid state today, with temps getting into the upper 50s and even the low 60s.
1242 PM EST Thu Nov 9 2017 Strong cold front tonight.
However, the Cascades, northern Washington, and the northern Panhandle will experience accumulating snow and pockets of light freezing rain this morning.
1045 AM MST Thu Nov 9 2017 Late night GOES-R water vapor loop depicted a deep upper trough over the Upper Midwest, an upstream ridge axis from the Four Corners to western MT, and an intense upper low spinning west of the Pacific Northwest coast. A cold front was located along the leading edge of lower clouds from central WY to central NE. The cold front will move southeast across the plains and stall along the Laramie Range this morning. Will see an increase in clouds, a wind shift to the northeast, and cooler temperatures behind the front. High temperatures east of the Laramie Range this afternoon will be 5-10 degrees cooler. Flow aloft backs to west-southwest as Pacific trough moves into the Northwest Friday. The next Pacific cold front will move into western WY by Friday evening.
/issued 1030 AM CST Thu Nov 9 2017/ Oklahoma and north Texas will remain on the periphery of a large area of cool high pressure today.
1135 AM CST Thu Nov 9 2017 16z/10am surface map shows a cold front extending from southern Lake Michigan southwestward to northern Missouri. High temperatures will range from the lower 40s northwest of the Illinois River. to the lower to middle 50s south of I-70. High pressure ridge axis over the region this morning, with little in the way of cloud cover for most of the night. Temperatures have dropped below freezing across Central IL, providing a chilly start to the day. A dry cold front moving through the region today will bring down a shot of cP air into the Midwest and result in a very cold night.
Warm front coupled with mid level forcing ahead of a S/WV trough will result in increasing chances for snow later this evening and after midnight north. The high temperature forecast for today ranges from the low teens north, to the upper 20s south. The low mentioned above will swing through far northeast North Dakota by Friday night. An upper level ridge looks to build in by the end of the weekend bringing a warming trend and temperatures near or even above normal for many.
1204 PM EST Thu Nov 9 2017 A weak area of low pressure will pass south of Pennsylvania today.
Warm front coupled with mid level forcing ahead of a S/WV trough will result in increasing chances for snow later this evening and after midnight north. The high temperature forecast for today ranges from the low teens north, to the upper 20s south. The low mentioned above will swing through far northeast North Dakota by Friday night. An upper level ridge looks to build in by the end of the weekend bringing a warming trend and temperatures near or even above normal for many. High pressure will maintain VFR conditions this afternoon across all of west and central North Dakota. Expecting increasing VFR cigs this evening ahead of a low pressure system that moves into our area from across the Rockies.
The cold front has pushed a little further southeast, pushing past Apalachicola, FL, Tallahassee, FL, and Valdosta, GA at this point. Overnight, cooler air will begin to move in, though cloud cover through a good part of the night will prevent us from dropping below 45.
228 PM CST Thu Nov 9 2017 Tranquil weather will continue across the Mid-South through the early part of the weekend as high pressure will dominate the weather pattern. However first, a reinforcing cold front will move through the area tonight. In fact, there will be little, if any cloud cover with it, but it will keep temperatures cooler through Friday Night.
1106 AM CST Thu Nov 9 2017 Drier air continues to move into the region as high pressure builds across the region today. Early morning temperatures range from near 40 across Southeast Oklahoma to the upper forties across Deep East Texas and the lower parts of Northwest and North Central Louisiana. Drier air associated with the high pressure on the surface and aloft will allow for more sunshine returning during the day with daytime highs warming to near 60 to the middle sixties. For parts of Southeast Oklahoma and parts of Southwest Arkansas could see some readings near freezing late tonight near Battiest and around De Queen. By late Friday, zonal flow aloft will be returning as the upper ridge flattens and a re-enforcing cold front back doors across the forecast area, but it will be a dry system.
255 PM CST Thu Nov 9 2017 A cold front pushed through most of eastern Missouri and southwest Illinois this afternoon. High pressure will build into the region behind the front bringing the coldest air of the season so far. LJB A sunny but cold day is ahead Friday for the bi-state region with lighter winds as 1038 mb Canadian high pressure settles into the western Great Lakes. Highs Friday to range from the mid to upper 30s north of St Louis/I-70 to the lower 40s south with mid 40s far southern reaches of CWA.
330 PM CST Thu Nov 9 2017 Cold high pressure continues to slowly drift east tonight, setting us up for southeasterly flow on Friday. And while lows may drop to around 32 in some areas, by the time the drizzle begins, it should warm to above freezing.
232 PM CST Thu Nov 9 2017 Taking a look at the latest surface analysis, the high is set up over the eastern third of ND, with a ridge extending across the eastern third of SD and into our west central MN counties.
225 PM CST Thu Nov 9 2017 Cold front will continue to settle southward into the Ohio River Valley. Given upstream dewpoints in the single digits and teens across the Dakotas into northwest Iowa, low temperatures will drop well below freezing despite less than optimal radiational cooling conditions. High pressure will build eastward across the Great Lakes on Friday, providing a continued cold/dry E/NE flow.
Locally, it has been gusty and cold today behind a cold front which is now moving through the Ohio Valley. Afternoon temps across the forecast area ranged from around 30 F NW, near Independence, to the low 40s over the SE. Some of the 12Z raw model guidance (GFS/ECMWF) has come in slightly warmer than the current forecast, likely due to boundary layer mixing effects. Friday Well below normal temps in the lower to middle 30s with SE sfc winds of 10-15 mph. Today's early morning discussion follows: Friday: Arctic high pressure (1039 mb) will settle into Great Lakes region providing the dvn cwa with another cold day.
As this trough finally shifts east and higher pressure builds in from the west the clouds will finally start to break from west to east through mid afternoon.
224 PM MST Thu Nov 9 2017 Main forecast concern will be low probabilities for freezing fog and freezing drizzle between about 06z tonight and 18z Friday. Cold front has pushed into the panhandles with shallow cold air mass building into the central High Plains. After midnight, will start to see the low levels gradually saturate from west to east, with low level warm advection/isentropic lift just above the saturated layer. All in all, confidence is lacking for an advisory, but will carry patchy wording for freezing fog/drizzle as not to totally discount the possibility. Eastern areas may stay cloudy well into the afternoon and temperatures may struggle to reach even the lower 40s that are forecast.
244 PM EST Thu Nov 9 2017 Rain and low clouds will continue over the region through this evening as an upper level trough currently over western GA moves eastward and across the Midlands this evening. High pressure along with cold dry air will begin building into the area during the early morning hours Friday and remain over the area through the weekend.
Another foggy morning ahead of a cold front on Friday. An approaching cold front will bring an increasing chance for showers, and the potential for thunderstorms, to round out this work week. Showers and thunderstorms will be possible on Friday as the front passes with a focus along the east coast where the highest available moisture will be.
1021 AM CST Thu Nov 9 2017 16z/10am surface map shows a cold front extending from southern Lake Michigan southwestward to northern Missouri. High temperatures will range from the lower 40s northwest of the Illinois River. to the lower to middle 50s south of I-70. High pressure ridge axis over the region this morning, with little in the way of cloud cover for most of the night. Temperatures have dropped below freezing across Central IL, providing a chilly start to the day. A dry cold front moving through the region today will bring down a shot of cP air into the Midwest and result in a very cold night.
The front will slowly limp through the area overnight and into Friday as high pressure quickly builds in behind it. The high will tighten the pressure gradient across the area and allow winds to increase and become gusty for Friday afternoon. Slightly cooler and drier air will also be filtering down the state, with lows tonight in the mid 50s to lower 60s north, and in the lower to mid 60s inland to mid to upper 60s coastal for the central and southern zones. Highs Friday will range from the mid 70s north to the lower 80s south. For the weekend: Aloft a short wave trough off the southeast U. coast slides out over the Atlantic as ridging builds above Fl from the Gulf of Mexico.
1252 PM EST Thu Nov 9 2017 As an upper level system and strong cold front approach there will be a low chance of some light rain showers into the evening, mainly north of Route 6. Low temperatures overnight will drop into the upper teens to the lower 20s. A strong cold front will sweep across the area today.
1030 AM CST Thu Nov 9 2017 Oklahoma and north Texas will remain on the periphery of a large area of cool high pressure today.
1151 AM CST Thu Nov 9 2017 The cold front is just about through the forecast area reaching into north central Kansas as of 3am. There could be a chance for patchy freezing drizzle late tonight over southwest portions of the area with lift across the area. The GFS is much warmer. the low 30s NAM and mid-upper 40s GFS. Despite warm air advection at the surface, do think it could be on the cooler side with the persistent cloud cover.
1036 AM CST Thu Nov 9 2017 Surface analysis early this morning shows a cold front extending NE-SW from lake Superior through WI into northwest IA on into Nebraska with arctic high pressure trailing it straddling the Canadian border between Saskatchewan province and the Dakotas. Aloft, a longwave upper level trough axis is swinging southeast through the Upper Mississippi River valley with solid northwest flow aloft in its wake. Clouds may be a little slow to erode due to the sluggish progression of the upper trough but the clearing will come by this afternoon. The mainly clear skies will then prevail through tonight as the high pressure area moves atop MN/WI. Thus, despite some sunshine later today, the strong cold air advection will translate to highs ranging from the mid-teens to the lower 20s.
300 PM CST Thu Nov 9 2017 Skies have just about cleared across the cntrl TN Valley this Thu afternoon, with just a few lingering clouds continuing to drift ewd in association with a sharp upper trough axis beginning to cross into the srn Atlantic Basin. N winds around 10 MPH are firmly entrenched across the region, or more specifically sandwiched between 2 cold fronts. The quiet and tranquil wx pattern will definitely continue into the end of the work week, as a strong dome of high pressure out of the nrn/mid Plains states begins to build towards the SE in the wake of the dry frontal passage.
234 PM CST Thu Nov 9 2017 Cloudy conditions will continue through Friday despite high pressure being over the region. For tonight, have removed the freezing drizzle/drizzle potential as models are indicating enough low level dry air to limit any drizzle from reaching the ground. Overnight lows will be slightly warmer than the previous couple nights due to cloud cover expected across much of the forecast area tonight. With cloud cover combined with breezy winds, will keep temperatures east of US-83 on the cooler side (upper 30s to low 40s). Temperatures towards the eastern Panhandle and southwest Nebraska will see slightly warmer highs on Friday in the mid 40s to low 50s.
Templer Previous discussion: High pressure over northeast Montana early this morning. Some fog possible with the low clouds along with very light flurries for this morning. High pressure moves east today, with jet pushing across the Pacific Northwest. These increasing winds should also help mix out the inversion and dissipate the low clouds. This will bring a warm front through eastern Montana, with the potential for a few snow showers mainly near the Canadian border. As the low moves into southern Saskatchewan during the day, a cold front will sag southward across the border, maintaining the potential for snow showers. Weak high pressure slides into eastern Montana Friday night as the Saskatchewan low moves east.
144 PM EST Thu Nov 9 2017 Strong cold front tonight.
1008 AM MST Thu Nov 9 2017 A ridge will continue moving over the area today with dry conditions and high temperatures warming 5 to 10 degrees. A weak upper vort max is riding through the ridge providing some uplift for higher level clouds and drawing moisture into the area. Late tonight and Friday the ridge will have moved east and a strengthening southwest flow aloft will continue to bring dry conditions. The large scale upper air pattern over the CONUS will shift from an amplified progressive pattern to a more zonal flow over the next few days, as a series of upper level lows track from the Gulf of Alaska toward the Pacific Northwest.
1121 AM CST Thu Nov 9 2017 Early morning clouds have cleared out nicely with the erosion of the low level inversion, with predom mostly clr skies in its wake across NW/N cntrl AL. The coldest/driest air over the CONUS will remain centered over the Upper Midwest and southern Canada behind a second stronger cold front that will not push through the area until late tonight. Despite abundant sunshine on Friday, highs should only reach the lower to mid 50s in most locations on Friday.
An upper low off the coast will rotate a few rounds of showers across Western Washington today. This low will weaken and move across Western Oregon on Friday, bringing continue rain to Southwest Washington but a drier break for Northwest Washington on Friday and Friday night.
115 PM EST Thu Nov 9 2017 Strong cold front tonight.
1107 AM EST Thu Nov 9 2017 A weak area of low pressure will pass south of Pennsylvania today.
Thick low clouds and patchy fog across parts of eastern New Mexico and the lower Rio Grande Valley this morning will dissipate through lunch time.
257 PM EST Thu Nov 9 2017 A cold front will move across the region late this afternoon and this evening. High pressure will build in for the end of the week.
312 PM CST Thu Nov 9 2017 A cold front currently across central Missouri into Kansas will surge into the are Tonight resulting in below freezing temperatures again Tonight across portions of northeast Oklahoma and northwest Arkansas.
1226 PM EST Thu Nov 9 2017 A cold front will move across the region late this afternoon and this evening. High pressure will build in for the end of the week.
1127 AM CST Thu Nov 9 2017 /18Z TAFS/ The low clouds have cleared out of the northern terminals, and are beginning to dissipate across the southern terminals.
Cloud cover was increased some in the gridded forecast to account for the high cloudiness spreading over the region today. It'll be a chilly start with several locations below freezing. Models have been consistent in dropping a weak backdoor cold front into the area on Friday which will aid in knocking afternoon highs down just a few degrees across parts of far northeast OK into northwest AR.
Issued by National Weather Service DODGE CITY KS 1130 AM CST Thu Nov 9 2017 Surface cold front associated with the upper trof moving across the Upper Midwest/Great Lakes today will drop south across central and southern Kansas. Stratus development is expected across western Kansas in the low level warm advection regime, though some of the low clouds may develop east into parts of central Kansas during Friday.
159 PM EST Thu Nov 9 2017 As an upper level system and strong cold front approach there will be a low chance of some light rain showers into the evening, mainly north of Route 6. Low temperatures overnight will drop into the upper teens to the lower 20s. Cold front moving through the forecast area this afternoon but latest KIWX radar loop showing just a few returns north of the CWA so have cut back on POPs remainder of the afternoon as front pushes through NE CWA. Water vapor imagery depicting strong upper low just off the Pacific NW coast will weaken significantly as it comes onshore Friday and quickly traverse western/mountain CONUS and provide short wave energy that will affect our area for this weekend.
318 PM CST Thu Nov 9 2017 A large area of cool high pressure centered over the Plains will continue to be the dominant feature over the southern Plains for another day or so.
Early morning clouds have cleared out nicely with the erosion of the low level inversion, with predom mostly clr skies in its wake across NW/N cntrl AL. The coldest/driest air over the CONUS will remain centered over the Upper Midwest and southern Canada behind a second stronger cold front that will not push through the area until late tonight. Despite abundant sunshine on Friday, highs should only reach the lower to mid 50s in most locations on Friday.
1151 AM CST Thu Nov 9 2017 Lowered the high temperatures across the northern Red River Valley and northeast North Dakota for today due to the cold start and snow cover. Highs across the forested areas of Minnesota should be a little warmer in the upper teens due to the sunshine on the pine trees. surface temperatures across northeast ND and the northern RRV should continue temperatures to cool into the low sub-zero range. Fair skies and overall light winds still still allow for substantial radiative cooling so that overnight lows will likely settle into the low single digits south and low sub-zero range in the north.
/issued 1040 AM EST Thu Nov 9 2017/ A cold front will be pushing into the area today and tonight, with strong high pressure to the north ridging into the area behind it. A cold front will be pushing into the area today and tonight with strong high pressure to the north building into the area behind it. Winds and seas will be on the increase tonight and into the weekend as the high builds and the pressure gradient over the waters tightens.
Weak low pressure over NW North Carolina will shift farther east and drier air mass filters in. A dry cold front over the Ohio Valley this afternoon will pass through overnight.
259 AM CST Sat Dec 23 2017 The last of the convection is making its way e of our region this morning, and a much cooler airmass is taking hold in the wake of a cold front. Warmer temps expected for Sunday, as a brief return of sly winds ahead of another cold front will help us to reach into the 50s to near 60 for portions of the region. Impulse in nw flow aloft and associated cold front will bring widespread cloud cover, but moisture expected to be too limited to see any precip with the fropa.
A short wave moving across the Plains Sunday forces a strong cold frontal passage midday to afternoon.
Highs tomorrow will only recover a bit into the low to mid 20s, with lows tomorrow night into Sunday morning falling into the low teens.
401 AM EST Sat Dec 23 2017 Rain is expected with crossing low pressure today. Snow chances return Sunday with another area of low pressure. An associated cold front is expected to cross the area later this morning/early afternoon as the low advances NEWD to srn New England. Advisory level snow of 2-4 inches is possible near the I 80 corridor and in the ridges, as the flow shifts NW and results in some lake and terrain enhancement on the wrn side of the departing low Sunday night.
A flat high pressure ridge anchored over the West Coast will ensure a continuation of dry and generally mild conditions through the remainder of the month.
Strong forcing along a cold front will bring a line of heavy rain showers to the area, with the possibility of low-end severe wind gusts from embedded bow segments within a convective line. Gradient winds ahead of the front will be gusty but below wind advisory criteria outside the mountains; will continue the current advisory for the higher elevations, adding the SW NC counties, and continue the SPS for the rest of the area.
912 PM PST Fri Dec 22 2017 It will be fair and dry through the weekend with a warming trend as high pressure builds aloft. Many low spots inland (including the lower deserts) will once again fall into the 30s overnight into Sat morning requiring a Frost Advisory. At this time it appears the freezing conditions will be patchy enough to leave the San Diego County Coast/Valleys out of the Advisory so the forecast in this area, will indicate patchy frost. After Sat morning, building high pressure aloft and rising dewpoints should be sufficient to limit freezing/frosty conditions to just a few spots. It will be warmer each day as well.
Currently expecting around 5 above zero across the south to the low/mid teens across the far northwest and west. Subtle height rises follow for Sunday with partly sunny skies and temperatures in the lower 30s.
Saturday looks fairly similar to today before the arrival of the Arctic cold front on Sunday.
The northwest edge of a widespread light wintry mix of freezing rain/sleet and snow will affect a few of the southeast corner counties of Kansas, though expected to stay primarily just south of the KCNU terminal. MVFR cigs along and east of the Kansas turnpike this evening will improve in the wake of the departing trof later tonight.
322 AM EST Sat Dec 23 2017 Rain is expected with crossing low pressure today. Snow chances return Sunday with another area of low pressure. An associated cold front is expected to cross the area later this morning/early afternoon as the low advances NEWD to srn New England. Advisory level snow of 2-4 inches is possible near the I 80 corridor and in the ridges, as the flow shifts NW and results in some lake and terrain enhancement on the wrn side of the departing low Sunday night.
Current large-scale pattern depicts a trough diving down from the PacNW while Utah remains under a northwesterly 500mb flow. By tomorrow afternoon, the aforementioned trough will graze northeast Utah, turning the flow more northwesterly and resulting in a brief period of 700mb cold advection. Given the warm advection pattern and cloud cover, overnight mins tonight are not expected to be especially cold, and in fact, many areas should be quite a bit warmer than last night. Afternoon maxes across southern Utah should also trend warmer tomorrow, but this will not be the case across much of the north given the expected snowfall.
1019 PM CST Fri Dec 22 2017 Isentropic lift ahead of approaching cold front dropping southeast from North Dakota is producing light snow in northwest MN. While cooler air will filter in behind this front, temperatures won't plummet behind this front.
