(This afternoon through Wednesday night) The swirl of the upper level low centered over the Permian Basin is evident on both radar and satellite this afternoon. Abundant moisture and the spin of the upper low are good ingredients for cold air funnels which at least one has been observed near Midland/Odessa. A cold front moved through the area last night bringing northeasterly winds and much cooler temperatures. The low will still be close enough to the CWA to cause more showers and storms to develop tomorrow. The low will drift off to the west so the best rain chances will be west of the Pecos River, particularly the Davis Mountains and Big Bend, though the entire area will have one more day of decent rain chances.
1212 PM CDT Tue Aug 30 2022 A mid level trough is swinging through the Ohio Valley. The trough axis has moved east of the Mid-South along with its associated lift. Short range models show a bit of a lull after this last bit of showers pass, then scattered showers will push through this afternoon as a cold front dives from the north into the region.
An impressive ridge of high pressure is draped over the western U. This ridge will remain the primary talking point for the forecast well into the weekend, if not beyond. Most notably, Highway 95 along the Lower Salmon River valley including Riggins will see temperatures flirt with 110 degrees on Wednesday.
An upper level ridge will strengthen and expand across the desert southwest over the next few days and will remain nearly stationary throughout the 7 day forecast period.
Issued by National Weather Service Pueblo CO 213 PM MDT Tue Aug 30 2022 Upper ridging out west will keep dry weather and clear skies over the area tonight. upper high on Wednesday sending a cold front through the area in the afternoon. Thunderstorms will develop along this front in the early afternoon for northeast areas and translate southward across the remainder of the plains through the evening as outflow boundaries reinforce the cold front. -KT Convection will shift off to the east and southeast Wednesday night as the upper trough departs.
1153 PM EDT Thu Oct 10 2019 A ridge of high pressure will remain over central Pennsylvania through Friday.
332 AM EDT Fri Oct 11 2019 Dry weather and warmer temperature can be expected today under high pressure. Shower chances return with a Saturday cold front.
Rain and thunderstorms are leading a cold front, stretching from the Upper Midwest southwestward into the Southern Plains. As high pressure is shoved east, rain will be arriving in western counties around or shortly after lunchtime. By lunchtime Saturday, the spigot shuts off and we are left with much cooler temperatures. cooler, as in 50s and 60s for afternoon highs.
215 AM EDT Fri Oct 11 2019 A ridge of high pressure will remain over central Pennsylvania through Friday.
Highs were adjusted upward to the lower to mid 40s southwest, while mid 30s north central. Lows from the upper teens to lower 20s west, to the lower to mid 20s east. The closed upper low will remain across northern Minnesota on Saturday.
The upper level low across SD this morning will move east and steepen 850-700mb lapse rates as shown by the RAP model soundings. 1034mb high pressure across WY will produce Bora conditions today and tonight. The high pressure system will begin to release it's grip Saturday with h850mb temperatures rising to around 5C.
116 AM EDT Fri Oct 11 2019 A ridge of high pressure will remain over central Pennsylvania through Friday.
718 AM EDT Fri Oct 11 2019 A ridge of high pressure will remain over central Pennsylvania through tonight.
236 AM PDT Fri Oct 11 2019 Temperatures will trend warmer today through Saturday as high pressure moves across the region.
858 AM EDT Fri Oct 11 2019 Dry weather and warmer temperature can be expected today under high pressure. Shower chances return with a Saturday cold front.
Expect many locations to start the morning near record minimum temps, though pocket of low cloudiness earlier this morning has kept Pueblo slightly warmer than surrounding areas so far. Expect a sunny/dry day across the entire region today in the wake of departing upper level low pressure, with some breezy to windy spots over the higher peaks as strong mid-level flow is slow to subside. Max temps well below average at all locations, though warmer than yesterday with less wind. Overnight, mid level heights/temps begin to rise as upper level ridge builds over the wrn U. Still expect most locations to decouple and drop well below freezing, though just enough west wind may appear to nudge ern mountains slope temps slightly upward toward Sat morning.
Strong and cold upper low slowly moving toward the north central portion of the country. Made little if any changes to the high temperature forecast. There is some difference in the high temperature guidance. Generally stayed near the warmer 2 meter/bias corrected 850 mb temperature guidance which was also close the forecast blend. Again due to the lightest winds in the east, lowered the low temperature guidance there.
/issued 250 AM CDT Fri Oct 11 2019/ High pressure and cold air continue to push into the South Plains behind yesterday's strong cold front. This may be enough to keep temperatures above freezing for those areas that don't experience a freeze this morning. The only feature of note is a low-amplitude upper short wave trough that is progged to move across the desert Southwest early in the week. Some modest differences in the sharpness of the trough and the position of the accompanying jet streak.
320 AM MDT Fri Oct 11 2019 Overnight WV/IR loop showed the stacked mid/upper low centered over central SD, with trowal/moisture wrapping back to the western Dakotas. Current model/ensembles maintain the intense upper low pressure system as it tracks northeast into MN today and tonight. The low gradually fills as it drifts east across the western Great Lakes this weekend. It will be 10 to 15 degrees warmer this afternoon with 700mb temperatures from -4 to -8 Celsius.
This is indicative of the ridge of high pressure that is ongoing in our area. With that, a thermal trough is occurring through our area with winds from the east this morning and afternoon. Temperatures at the coast will be in the upper 60s with West Side Valleys seeing temperatures in the low to mid 70s. Meanwhile, temperatures east of the Cascades will be in the low to mid 60s. This ridge of high pressure will be somewhat temporary as a frontal boundary moves across the Pacific Northwest this weekend. The most noticeable feature of this system will be increased cloud cover this weekend, which will help most of the West Side valleys move away from temperatures capable of producing frost of freezing conditions.
541 AM EDT Fri Oct 11 2019 Dry weather and warmer temperature can be expected today under high pressure. Shower chances return with a Saturday cold front.
A very dry and weaker northwesterly flow over SE AZ as the strong trough pushes into the Northern and Central Plains this morning.
Urban locations may stay just above freezing, but most outlying areas will see readings at or below freezing by Saturday morning.
Upper level ridging approaching from the west does bring some warming to the mountains but no other real changes aside from a bit more warming due to the erosion of snow cover.
The high will build east of the Carolinas this weekend with weaker easterly winds over the local waters.
Some of the lower/sheltered areas could see temperatures drop to near 28 or even colder briefly before sunrise. upper low.
/issued 355 AM EDT Fri Oct 11 2019/ An upper low moves northeast off the New England coast through Saturday. Upper ridging extends across the Gulf of Mexico, then northeast along the eastern seaboard. As the upper low moves north, a zonal flow sets up over the region as ridging extends from the western Gulf of Mexico eastward across the Florida peninsula. On the surface, an area of low pressure moves northeast off the New England coast and extends a frontal boundary southwest through the western Atlantic and over southern Florida.
The highly anticipated cold front has moved through the area, leaving behind much colder air. Freezing temperatures are once again anticipated Saturday morning across northern New Mexico and the upper Rio Grande Valley so be sure to continue to protect your pets, plants, and pipes from the cold.
/issued 344 AM CDT Fri Oct 11 2019/ Early Friday morning temperatures are in the low to middle 70s, and probably about as warm as we will see through the weekend across much of the Midsouth. A strong cold front has just moved through Fort Leonard Wood, Missouri and Mountain Home, Arkansas and will soon move into Western portions of the Midsouth. High temperatures over the weekend are expected to be in the low to middle 60s.
High pressure will slide east as a cold front approaches from the west during this taf cycle.
WINDS ARE EXPECTED TO DROP OFF FURTHER LATER THIS MORNING AND THIS AFTERNOON AS UPPER LEVEL HIGH PRESSURE CENTERS OVER THE WEST COAST. AS UPPER HIGH PRESSURE CENTERS OVER THE WEST COAST, DAYTIME HIGHS WILL WARM TODAY REACHING RIGHT AROUND NORMAL FOR THIS TIME OF YEAR. FAIR SKIES, DRY CONDITIONS, NEAR NORMAL TEMPERATURES AND RELATIVELY LIGHT WINDS WILL CONTINUE GOING INTO THE WEEKEND AS HIGH PRESSURE RIDGING SLIDES OVER THE WEST COAST.
1047 AM EDT Fri Oct 11 2019 Dry weather and warmer temperature can be expected today under high pressure. Shower chances return early tomorrow as a cold front passes.
421 AM CDT Fri Oct 11 2019 Sub-Freezing Weather. Our southeastern counties are still hovering just above freezing at 4 AM due to the gusty winds and clouds. In coordination with surrounding NWS offices to our southeast we will wait a few more hours to see if we end up freezing in places like Hebron and Beloit and then will consider possibly coordinating another freeze warning for areas that don't see a killing freeze this morning. Forecast looks to remain dry as the upper level low continues to lift and move over the Great Lakes region.
The highest additional snow totals of 6-10 inches are expected to be along the Coteau and Leola hills where upslope forcing will enhance snowfall.
The Florida Keys remain under the control of high pressure over the Eastern United States which supports moderate northeast to east breezes across the islands.
A ridge of high pressure will remain over the region through Saturday providing clear skies and light winds. Temperatures will be a little warmer today and overnight but overall temperatures will continue to be cooler than normal.
556 AM EDT Fri Oct 11 2019 A ridge of high pressure will remain over central Pennsylvania through tonight.
633 AM CDT Fri Oct 11 2019 Upper level trough with an anomalous cold air core has brought winter weather to the upper plains. Wind gusts of nearly 40mph made it feel all the cooler. By 0Z Saturday morning, wind speeds will slow and temps will begin to slip sub-freezing in northern Nebraska. While temperatures will be 5 to 15 degrees warmer, they'll remain below seasonal norms with highs ranging from the mid 40s north to near 60 along the KS state line.
Second, confidence is much lower in an additional freeze across southern and eastern sections for late tonight into Saturday morning, so have kept mins just above freezing in those sections for this pckg. There will be a couple dry cold frontal passages, none of them as strong as the one that brought sub-freezing temperatures to much of the fcst area this morning.
As a cold front approaches from the west, clouds will continue increase from the top down, however VFR conditions are expected to continue until mid-afternoon Friday.
The wind profile should get a little more sheared eventually to reduce the mountain wave amplification, but the flow aloft will only decrease slightly so it will stay windy over the higher ridges. The cold air at the surface will limit how much wind mixes down, so the strong winds should stay over the higher elevations and along the Cheyenne Ridge, with Denver on the edge of the less strong northwest winds across the plains. Over the weekend, a weak northwesterly flow aloft will be over the forecast area on Saturday, it will then transition to more of a westerly flow as a mid level ridge axis moves over the state.
/issued 328 AM CDT Fri Oct 11 2019/ After record hot temperatures yesterday afternoon, we are seeing much colder conditions this morning behind a strong cold front. Lows near freezing are still expected this morning across northern Lea Co. High winds through Guadalupe Pass and the Delaware's will continue through the morning so will leave the High Wind Warning there as is. Lows in the 30's and 40's will be common, but it appears temperatures will remain above freezing for areas that haven't seen a freeze yet.
700 AM CDT Fri Oct 11 2019 Sub-Freezing Weather. Our southeastern counties are still hovering just above freezing at 4 AM due to the gusty winds and clouds. In coordination with surrounding NWS offices to our southeast we will wait a few more hours to see if we end up freezing in places like Hebron and Beloit and then will consider possibly coordinating another freeze warning for areas that don't see a killing freeze this morning. Forecast looks to remain dry as the upper level low continues to lift and move over the Great Lakes region.
624 AM EDT Fri Oct 11 2019 A dry pressure ridge will dominate through tonight. A cold front will approach Saturday. Expect highs in the low to mid 80s. Temperatures should be warmer Friday night compared to the previous night. We leaned toward the higher temperature guidance which is usually best just ahead of cold fronts. The models have been consistent with moisture diminishing along the front with lingering h5 ridging plus h85 ridging along the Gulf Coast further limiting moisture.
Sharp surface cold front currently roughly along the Mississippi River from MN to central IL. Potent upper low behind this feature is located along the SD/NE border and generating some heavier snows over the Dakotas. Welcome to fall! The cold front will have pushed well east of central Kentucky by daybreak on Saturday, but low clouds may linger near the I-75 corridor.
High pressure will continue to build over western Montana and central Idaho through Saturday.
In areas with fewer low clouds like the North Bay, current temperatures are running much cooler than those from 24 hours ago. Current temperatures in the North Bay Valleys are in the lower 40s.
549 AM EDT Fri Oct 11 2019 Dry weather and warmer temperature can be expected today under high pressure. Shower chances return with a Saturday cold front.
524 AM EDT Fri Oct 11 2019 A ridge of high pressure will remain over central Pennsylvania through tonight.
535 AM MDT Fri Oct 11 2019 Overnight WV/IR loop showed the stacked mid/upper low centered over central SD, with trowal/moisture wrapping back to the western Dakotas. Current model/ensembles maintain the intense upper low pressure system as it tracks northeast into MN today and tonight. The low gradually fills as it drifts east across the western Great Lakes this weekend. It will be 10 to 15 degrees warmer this afternoon with 700mb temperatures from -4 to -8 Celsius.
Rainfall has caused flooding in southern MO with the highest impacts in the Branson and Roaring River State Park areas so far. A weak ridge of high pressure will move through the region tonight with light winds.
Currently, a cold front is moving through the state towards the SE, resulting in strong sustained NW winds of 15 kts, with gusts up to 20 kts possible.
Patchy drizzle and freezing drizzle could mix in before sunrise, but most locations with deep enough saturation for drizzle remain just above freezing at the surface, minimizing any icing concerns. Flurries and light snow showers due to shallow lift in the low levels will generally bring less than an inch of additional accumulation throughout the late morning and afternoon. Accumulations to the casual observer will likely seem less than this, as daytime temperatures near freezing, diffuse sunlight, and warm ground work to melt the intermittent light snow. Other important aspects of the forecast in the near term include gusty northwest winds and sub-freezing temperatures the next couple mornings. The combination of lows in the high 20s with winds gusting 30 to 40 mph will cause morning wind chills to be in the teens and low 20s.
124 PM MDT Fri Oct 11 2019 The return to milder conditions will commence in earnest today with the trough departing and H5 ridging building across the intermountain west. Southwest surface winds will begin the remove any traces of the previous cold snap, bringing highs back into the 40s and 50s for all but the highest elevations for Saturday.
High pressure was currently located across the Texas/Oklahoma panhandle region and will slowly slide east tonight. Even with a slight south wind developing by morning, model guidance has come in slightly colder with lows tonight, with most locations dropping below freezing, potentially for three or more hours, therefore the Frost Advisory was upgraded to a Freeze Warning for the overnight hours. Typical low spots and valleys will likely drop into the lower to middle 20s. Strong upper level low across the northern US will slowly move east through the weekend, with conditions slowly moderating a little each day and remaining dry.
1147 AM EDT Fri Oct 11 2019 A ridge of high pressure will remain over central Pennsylvania through tonight.
1027 AM MDT Fri Oct 11 2019 Overnight WV/IR loop showed the stacked mid/upper low centered over central SD, with trowal/moisture wrapping back to the western Dakotas. Current model/ensembles maintain the intense upper low pressure system as it tracks northeast into MN today and tonight. The low gradually fills as it drifts east across the western Great Lakes this weekend. It will be 10 to 15 degrees warmer this afternoon with 700mb temperatures from -4 to -8 Celsius.
133 PM EDT Fri Oct 11 2019 A dry pressure ridge will dominate through tonight. A cold front will approach Saturday. Expect highs in the low to mid 80s. Overnight temperatures expected to be slightly warmer than last night with some high clouds approaching around dawn. Dry high pressure will continue to dominate going into Saturday, and temperatures will warm into the mid to upper 80s. A cold front will then move into the region Saturday night and stall across the Upstate.
This may then allow these aforementioned areas to reach freezing early Saturday morning. Zonal flow aloft will persist through the weekend which will promote surface lee cyclogenesis/pressure troughing for the next several days. Southwesterly downsloping winds will ramp up by Saturday afternoon leading to a much warmer day than today.
Overall, still a little on the cool side to start the week, with warmer, and potentially windier, weather to end the week.
244 PM CDT Fri Oct 11 2019 Strong upper level ridging will remain in place across the western US through Saturday night. Despite plenty of sunshine, cold air advection into the region behind the departing low over the upper Great Lakes will keep temperatures on the cooler side. Highs Saturday afternoon will range from the mid 40s in the north to the low 60s south of I-80. Overnight low temperatures will also be chilly with lows in the low to mid 20s tonight. Lows Saturday night will be slightly warmer in the low to upper 20s. High pressure and quiet weather will continue through the remainder of the forecast period.
An upper level ridge will make today sunny in Western Washington.
High pressure building into the region at the surface will bring clear skies and VFR conditions thru the forecast period. KBVO will see an increase in SW wind toward the end of the period on the north side of the surface anticyclone. The cold front that moved thru yesterday is now pushing into the lower Mississippi and Ohio Valleys. High pressure will continue to build into the area, and winds are expected to drop off by late afternoon. Urban locations may stay just above freezing, but most outlying areas will see readings at or below freezing by Saturday morning.
217 PM EDT Fri Oct 11 2019 A ridge of high pressure will remain over central Pennsylvania through tonight. A weakening cold front will sweep across the area Saturday afternoon.
340 PM CDT Fri Oct 11 2019 Early afternoon water vapor imagery shows the upper low center pivoting over northern Minnesota. As the low circulates over northern Minnesota on Saturday and sags slightly south, scattered snow showers will become likely area-wide, with gusty west/southwest winds persisting. This is on the lower-end of some of the snowfall guidance, given models inability to account for the melting that will occur at the beginning of the event.
253 PM MDT Fri Oct 11 2019 An upper level ridge of high pressure will slowly build over the region during the weekend.
408 PM EDT Fri Oct 11 2019 A ridge of high pressure will remain over central Pennsylvania through tonight. A weakening cold front will sweep across the area Saturday afternoon.
Tonight and Saturday Showers continue to end from west to east as a cold front moves away from the western Great Lakes region. Temperatures also continue to fall or stay steady behind the cold front, as most locations are in the 40s with some 30s across north-central Wisconsin. Despite cloud cover and blustery conditions, temperatures are expected to continue plummeting tonight, falling below freezing across most of the area. Given the lower temperatures will expand the Freeze Warning east to the lakeshore save for Door County which should be a bit warmer being surrounded by fairly warm water. Highs on Saturday are only expected to rise into the upper 30s across the north, with highs in the lower to middle 40s across the south. Saturday Night Through Friday Much cooler than normal daytime temperatures will persist through most of the upcoming week.
We have lows forecast in the lower to middle 30s. High pressure will slowly shift east to the eastern seaboard during that time frame, allowing southerly winds to return to the region.
This low will swing northwestward overnight. Models are showing some light freezing rain during this period with the loss of ice aloft.
When showers trailing behind the cold front pass, skies will start to clear and winds will calm and temperatures will dip down to the upper 30s for most of the area by tomorrow morning, promoting patchy frost for most of eastern Arkansas and western Tennessee.
High pressure will continue to be the dominate feature across western Kansas through tomorrow bringing mostly clear skies and dry conditions. Models continue to suggest a cold front to move through the area around the beginning of the week but no precipitation is expected at this time with only a slight increase in cloudiness.
In the wake of the strong cold front that moved through the area last night, very dry air has moved into western Texas with dewpoints dropping into the upper teens to lower 20s. Temperatures should drop quickly through the evening and hit the freezing mark during the early morning hours. Confidence in other areas hitting freezing is low at this time for areas south of the Interstate 20 corridor.
Northeasterly BL flow across the region off of a N Rocky high pressure behind yesterday's cold front has perpetuated the plunge of surface dewpoints into the single digits that began yesterday and this morning. Expect near normal warm temperatures this weekend near 90 degrees and barely above normal highs for the remainder of the week in the low 90s with periodic bumps in H5 heights.
A strong cold front will exit Indiana this evening.
The abnormally cold airmass in place across the state will gradually warm as high pressure aloft builds into the region during the upcoming weekend. As expected many records have fallen with the lows being reported so far this morning. Temperatures will gradually moderate as stout warm air advection continues and the upper level ridge builds into the area.
Overall, the least impacts have been felt so far from Crookston to Fargo-Moorhead to Wahpeton- Breckenridge-Fergus Falls.
