1047 AM CST Fri Feb 10 2023 (Now through Saturday) Latest surface analysis shows a cold front extending from north of Laredo to southeast of San Antonio. The frontal passage will be mainly dry, however, some shower activity and a possible rumble of thunder could develop over the lower Valley, coastal sections, and the marine areas. In the wake of the front, cooler and drier air will filter into the region. Today will be breezy with highs in the low to mid 60s with a mix of sun and clouds. Can't rule out an isolated freezing temperature here or there.
200 PM CST Fri Feb 10 2023 High pressure continues to build into the region in the wake of a departing upper trough, with cool and dry northwest winds pushing this morning's stratus out of the region. The combination of clear skies and light winds associated with the high will result in efficient radiational cooling tonight, pushing lows into the mid to low 20s for most of the area. Meanwhile, the southern portion of the above upper trough is in the process of becoming cut off from the westerlies, and is expected to track from the Southern Plains this afternoon, through the Lower Mississippi Valley and into the Deep South by tomorrow night. In response, low level troughing will deepen to our south, resulting in dry northeasterly flow across our region for much of the day on Saturday.
Upper trough along 130W has closed off a low off the southern Oregon Coast. The closed low is forecast south along the California Coast through the weekend and just close enough for a slight chance of flurries in Harney County late tonight. The weaker northern part of the trough will move inland and slightly lower our temperatures Saturday.
Lows will be in the lower to mid 20s. Expect dry and slightly warmer conditions along with light winds Saturday.
211 PM EST Fri Feb 10 2023 Upper air pattern consists of a 500 mb trough on the west coast, a trough in the southern plains and a trough in the lower Great Lakes.
(The rest of this afternoon / Tonight ) Areas of rain continue to spread across far southeast Oklahoma/ west-central Arkansas in association with upper low moving east across north Texas. Some snow accumulation will remain possible in the higher terrain of the Ouachitas through mid evening before upper low begins to pivot/shift southeast. (Tonight through Friday) Warming trend is expected through the weekend as upper ridge briefly builds over the southern Plains.
(This afternoon through Saturday night) Upper trough moving out of the area today as ridge moves in. Ridge will be right over the region Saturday as the next upper low moves down the CA coast.
This trend will continue throughout the rest of the afternoon and into the early evening (far south) as the high works into the area. During the overnight as the high pressure ridge moves into the forecast area, winds will become light. High pressure will continue to dominate on Saturday along with the dry atmosphere.
Looking at the bigger picture, an upper low can been seen swirling in central Texas in water vapor imagery. As far as our area, tonight winds are expected to remain around 10 mph which will limit radiational cooling, so lows are expected to only drop into the low to mid 30s. North winds will continue tomorrow with clouds building in during the afternoon as the upper low moves eastward and then lifts northward late Saturday. Models continue to support some rain/snow mix along the eastern third of the area with profiles completely below freezing above the surface. With lows around to even a degree or two above freezing, travel impacts aren't expected.
Cloud cover will continue to slowly erode from north to south through the late afternoon and evening as drier air associated with high pressure over the upper Midwest and central Plains works its way into the region. With clearing skies, decreasing winds and falling dewpoint temperatures, overnight lows should bottom out in the lower to mid 20s, with some upper teens in valleys over the eastern Ozarks.
(This evening through Saturday) Deep subsidence was in full swing this afternoon on the back side of an upper low now dropping southeast across N TX. At the surface, ridging is set to depart the South Plains soon after midnight ahead of light westerly winds. Temps moderate nicely for Saturday thanks to lee troughing with milder SW winds under a stout, but progressive ridge.
Quiet weather day across the area as an upper level ridge moves over the Central Rockies. Saturday and Saturday night look to be dry and warmer than normal with upper ridging over the forecast area.
Life-Threatening Rip Currents Continue at All Central Florida A cold front will move into north Florida and stall, with southerly winds transporting in more moisture through the afternoon. It will be another very warm day, with highs in the low to mid 80s and some locations, mainly across the interior, near their record highs for this date.
By 00z, warmer air moving in from the west will decrease the over-lake instability resulting in a decrease in clouds. And according to the latest visible imagery, once you get a few miles off shore, the nearest clouds are over Oregon! Thus the expansive area of high pressure will result in sunny skies over southwest Lower this weekend with clear skies Saturday night.
1031 AM MST Fri Feb 10 2023 High pressure will control the weather through the weekend and bring dry conditions through the period. With the higher sun angle and snow cover older now with less albedo, it may get a little warmer.
113 PM MST Fri Feb 10 2023 Water vapor analysis shows a broad ridge axis oriented NE to SW from Manitoba southward into the southwestern US. The upper pattern will remain stagnant the next few days as the upper trough across the Southern Plains slowly pivots eastward with the aforementioned western trough slowly digging into the SW US over the next few days.
1115 AM CST Fri Feb 10 2023 (The rest of today ) Upper trough axis continues to slide E-SE across Oklahoma this morning, with most precip confined to SE OK and WC AR. Upper trough will strengthen some as it continues to move through the forecast area, and this will likely keep precipitation going in the aforementioned areas through the afternoon. Rain will mix with snow at times, with all snow at times during the afternoon in the higher elevations of SE OK. Parts of the area will see sun this afternoon in the wake of the departing trough axis.
1202 PM CST Fri Feb 10 2023 The weak pressure trough currently sits along the ND/MN state line. To the west of this trough, southwesterly winds have contributed to solid warm air advection and weak downsloping. This trough will slowly push eastward this afternoon, giving a solid warm up for the Red River Valley and west. Our coldest spots, near Devils Lake, will see temperatures near freezing while the warmest temperatures will reach 40 degrees near Bemidji.
Environmental cooling is expected with the trough/frontal passage, but the extent of cooling with the NAM seems aggressive with the downward forcing of cold air along the low. In addition, the uncertainty of moisture return as the low swings through the south will also come into question, as some guidance has a drier solution, with the bulk of moisture being east of the low.
The low and its associated wrap-around moisture will take a more southward dive later this evening into tonight, placing the potential for a light rain/snow mix over our northeastern/eastern zones. One caveat to the snow potential is a ~1000-1500ft above-freezing near surface layer that could hinder the amount of snow that makes it to the ground. Cloud cover will keep overnight lows generally above freezing over the eastern portions of the CWA, whereas temperatures west of I-35 are expected to drop into the mid to upper 20s with mostly clear skies present. Afternoon highs are expected to rise into the low to mid 50s as light north-northwesterly winds prevail.
Saturday: Low-impact sensible weather looks to take hold as upper- level ridging slides overhead. A warming trend will commence, with afternoon highs in the low-50s across the eastern forecast area to upper-50s (perhaps a few 60s) across the west. Weak cyclogenesis across the high terrain will allow southerly flow to re-establish, especially across northwest/western Oklahoma.
255 PM MST Fri Feb 10 2023 With an upper level ridge of high pressure building over MT this weekend, expect fairly quiet weather conditions along with above normal temperatures.
356 PM MST Fri Feb 10 2023 Water vapor analysis shows a broad ridge axis oriented NE to SW from Manitoba southward into the southwestern US. The upper pattern will remain stagnant the next few days as the upper trough across the Southern Plains slowly pivots eastward with the aforementioned western trough slowly digging into the SW US over the next few days.
428 PM CST Fri Feb 10 2023 (This afternoon through Saturday night) Upper trough moving out of the area today as ridge moves in. Ridge will be right over the region Saturday as the next upper low moves down the CA coast.
540 PM PST Fri Feb 10 2023 A low pressure system will impact Southern California this weekend, with much cooler temperatures, breezy onshore winds and cloud cover blanketing the region.
347 PM CST Fri Feb 10 2023 (Issued 347 PM CST Fri Feb 10 2023) Tonight through Saturday night: High pressure will move through the area tonight into Saturday, bringing continued mostly clear skies. Winds will be lighter tonight under the high, picking back up out of the southwest on the back side of the departing high.
This will allow the 500mb ridge over the upper Midwest to flatten out and transition northeast Montana into more of a northwest flow.
A warmer airmass will accompany these southwest winds, and this will lead to a warmer afternoon on Saturday. Forecast guidance favors temperatures at 925 mb to warm to around +2C during the daylight hours of Saturday, which is about 4-5C warmer than todays values.
Guidance has shown good continuity in progging a closed low to stay largely south and east of the forecast area, while the region remains under zonal flow aloft.
526 PM CST Fri Feb 10 2023 High pressure continues to build into the region in the wake of a departing upper trough, with cool and dry northwest winds pushing this morning's stratus out of the region. The combination of clear skies and light winds associated with the high will result in efficient radiational cooling tonight, pushing lows into the mid to low 20s for most of the area. Meanwhile, the southern portion of the above upper trough is in the process of becoming cut off from the westerlies, and is expected to track from the Southern Plains this afternoon, through the Lower Mississippi Valley and into the Deep South by tomorrow night. In response, low level troughing will deepen to our south, resulting in dry northeasterly flow across our region for much of the day on Saturday.
/NEW/ /Through Saturday Evening/ An upper low currently positioned directly on top of North and Central Texas will move steadily southeast tonight, reaching the Gulf Coast near the TX/LA border Saturday morning. At the surface, northwest winds and cold air advection continue across all of the region in the wake of the attendant cold front, which has pushed well out into the Gulf. This precip will shift southeast across our northeastern zones this evening as the low moves south and east. Clouds should move out on Saturday as the upper low continues to move farther away.
504 PM CST Fri Feb 10 2023 (Tonight) A low pressure system along the OK/TX border will drop south and east tonight towards the Gulf Coast. The only other thing of note tonight is winds will stay elevated around 10 to 15 mph as the low pressure system gets closer to the area.
However, a ridge of high pressure is pressing across Lake MI. As the ridge passes, our winds back and warm/dry advection develops. Min temps will be mostly 10 to 20f, a smidge warmer along the nw lower MI coast. A somewhat nebulous surface pattern looks to develop across the region with elongated high pressure across the Ohio River Valley and a weak cyclone moving far to our north near Hudson Bay.
Key message : - Another cold overnight with single digit above zero wind chills - Windy and warmer Saturday afternoon - Elevated Fire weather conditions Saturday afternoon (see fire weather section) A tranquil weather setup in the short term with ridging driving the primary sensible weather through Tonight, followed by some weak lee troughing allowing for a more windy and warmer day on Saturday. Similarly, apparent temperatures (wind chills) will again be uncomfortable cold ranging from the teens east, to around 5 above zero on the higher terrain from Elkhart to Syracuse.
420 PM MST Fri Feb 10 2023 UPDATED AVIATION SECTION With an upper level ridge of high pressure building over MT this weekend, expect fairly quiet weather conditions along with above normal temperatures.
526 PM CST Fri Feb 10 2023 (This evening through Saturday) Deep subsidence was in full swing this afternoon on the back side of an upper low now dropping southeast across N TX. At the surface, ridging is set to depart the South Plains soon after midnight ahead of light westerly winds. Temps moderate nicely for Saturday thanks to lee troughing with milder SW winds under a stout, but progressive ridge.
Dry weather will continue through the weekend though there will be a fair amount of clouds around Saturday, in association with an upper low over CA.
548 PM CST Fri Feb 10 2023 An upper level low pressure system will track from the Southern Plains through the Lower Mississippi Valley then northeastward into the Appalachians by Saturday Night. As the upper low tracks toward the Appalachians, rain will begin to spread northeastward into areas of West Tennessee near the Tennessee River and Northeast Mississippi Saturday afternoon into Saturday Night.
523 PM CST Fri Feb 10 2023 (The rest of this afternoon / Tonight ) Areas of rain continue to spread across far southeast Oklahoma/ west-central Arkansas in association with upper low moving east across north Texas. Some snow accumulation will remain possible in the higher terrain of the Ouachitas through mid evening before upper low begins to pivot/shift southeast. (Tonight through Friday) Warming trend is expected through the weekend as upper ridge briefly builds over the southern Plains.
134 AM MST Sat Feb 11 2023 Most recent surface analysis shows low pressure situated in northeastern Colorado, with high pressure over northern Wyoming. At the upper levels, broad ridging sits over the northern and central plains, while an upper closed low sits over the west coast.
High pressure will steadily work into the area overnight, allowing skies to remain clear and winds to go light and variable to calm, which will allow temperatures to drop well below guidance as dry advection continues to drive dewpoints down as well. Most guidance appears to be several degrees warmer than what is expected, and going forecast handles this well with lows in the upper teens to mid 20s - would not be surprised to see some mid teens in the outlying areas, even. This trend will continue throughout the rest of the afternoon and into the early evening (far south) as the high works into the area. During the overnight as the high pressure ridge moves into the forecast area, winds will become light. High pressure will continue to dominate on Saturday along with the dry atmosphere.
A closed low is currently spinning off the coast of northern California, and the wrap-around moisture from this low will make its way into central Oregon overnight tonight. Surface winds will shift to north-northeast as this low tracks south of the forecast area Saturday morning and afternoon. Temperatures will be several degrees cooler Saturday in the wake of the low and parent trough over the Northwest U.
1018 PM CST Fri Feb 10 2023 (This evening through Saturday) Deep subsidence was in full swing this afternoon on the back side of an upper low now dropping southeast across N TX. At the surface, ridging is set to depart the South Plains soon after midnight ahead of light westerly winds. Temps moderate nicely for Saturday thanks to lee troughing with milder SW winds under a stout, but progressive ridge.
A cold front will move through the region late today and tonight, with increasing southerly winds ahead of it gusting close to 30 knots this afternoon. Rain chances remain on the low side until this evening, when increasing showers and storms are expected, along with MVFR or brief IFR conditions.
1028 PM CST Fri Feb 10 2023 High pressure continues to build into the region in the wake of a departing upper trough, with cool and dry northwest winds pushing this morning's stratus out of the region. The combination of clear skies and light winds associated with the high will result in efficient radiational cooling tonight, pushing lows into the mid to low 20s for most of the area. Meanwhile, the southern portion of the above upper trough is in the process of becoming cut off from the westerlies, and is expected to track from the Southern Plains this afternoon, through the Lower Mississippi Valley and into the Deep South by tomorrow night. In response, low level troughing will deepen to our south, resulting in dry northeasterly flow across our region for much of the day on Saturday.
The clear skies today will also lead to relatively warm conditions with highs in the low to mid 50s.
A cut off low pressure system will be drifting across the Gulf Coast states with zonal flow setting up over the Midwest today into tomorrow. At the surface, a high pressure will be building into the Ohio River Valley bringing warmer southwest flow into Michigan.
154 AM EST Sat Feb 11 2023 A strong high pressure ridge has settled across the region early this morning with clear skies and chilly temperatures. Exceptionally quiet mid winter pattern for much of the Ohio Valley this weekend as zonal flow resides north of twin cutoff upper lows.
In response, the deep layered ridge that was dominant over our region is steadily slipping eastward further into the Atlantic. As the ridge retreats, the local flow will become more confluent through the lower levels. While this evening's sounding indicated a rather pronounced inhibition zone based around 950 mb, the inhibitive layer is expected to wash out while the lower levels moisten through the overnight period. An Atlantic ridge will retreat further eastward into the Atlantic through the overnight period as a front advances southeastward through the Gulf of Mexico.
-Coulston With an upper level ridge of high pressure building over MT this weekend, expect fairly quiet weather conditions along with above normal temperatures.
1133 PM CST Fri Feb 10 2023 (This evening through Saturday Night) Base of upper trof situated across ncntl Tx will sag southeastward and overhead Saturday morning. Upper trof should make its way far enough east Saturday night to clear most of the wrap around cloud cover with it.
But with the high clouds overspreading the area, temps are bouncing back up there. Another quiet afternoon across eastern Idaho although we are seeing gradually increasing cloud cover as an upper-level ridge begins to give way to more a trough moving into the Pacific NW. These clouds SHOULD help to keep overnight lows warmer than what we've seen the past few days. Saturday highs look "milder" than what we've seen recently with much of the area likely to get above freezing with maybe some low 40s sneaking into the lower Snake and eastern Magic Valley.
152 AM EST Sat Feb 11 2023 High pressure will build over the area today bringing quiet weather.
852 PM PST Fri Feb 10 2023 A low pressure system will impact Southern California this weekend, with much cooler temperatures, breezy onshore winds and cloud cover blanketing the region.
Leeside troughing developing over eastern Colorado will deepen by mid morning as southwesterly winds increase to 20-30 mph gusts during peak heating of the afternoon. As a result of the warming downslope nature of the low level flow, expect afternoon high temperatures to push into the mid to upper 50s.
1029 PM CST Fri Feb 10 2023 (This afternoon through Saturday night) Upper trough moving out of the area today as ridge moves in. Ridge will be right over the region Saturday as the next upper low moves down the CA coast.
1024 PM MST Fri Feb 10 2023 Water vapor analysis shows a broad ridge axis oriented NE to SW from Manitoba southward into the southwestern US. The upper pattern will remain stagnant the next few days as the upper trough across the Southern Plains slowly pivots eastward with the aforementioned western trough slowly digging into the SW US over the next few days.
(Today) The upper low extending from southeast Oklahoma into portions of North Texas is becoming less of a nuisance early this morning, with only spotty snow showers ongoing in far southeast Oklahoma. Low clouds persist across most of the area south of I-40, but a general decreasing trend can be expected through the morning as the upper system finally dives southeastward into the Lower Mississippi Valley.
An almost summer-like omega block pattern is present across North America early this weekend with a mid/upper level ridge centered on the Rockies into the high plains.
Stubborn stratocu should dissipate this morning as high pressure slides eastward from the Ohio Valley. While not ideal given the high clouds, decent radiational cooling may allow minT to drop below 20F tonight across the northern tier.
A strong high pressure ridge has settled across the region early this morning with clear skies and chilly temperatures. Exceptionally quiet mid winter pattern for much of the Ohio Valley this weekend as zonal flow resides north of twin cutoff upper lows. The second upper low has a tandem surface wave with it that will lift out of the Gulf of Mexico later this morning then track northeast into the Carolinas by early Sunday. anticipate temperatures will fall back into the lower and middle 20s for much of the area prior to daybreak with a few of our typical cool spots slipping into the teens.
445 AM MST Sat Feb 11 2023 High pressure ridge aloft over Colorado today before shifting off into the central plains tonight. Thermal ridge will also be over Eastern Colorado this afternoon with warming at 700mb to around +4c. Warmest readings again at the base of the foothills with cooler readings along the S. Models still show a weak upper trough to push eastward across the forecast area Sunday. It will bring a slightly cooler airmass to the CWA on Sunday and very little moisture. There is weak upper ridging in place Sunday night.
A departing upper low pressure system will cause scattered showers across north Mississippi this afternoon and cooler temps elsewhere.
High pressure was across the Midwest with IR satellite showing clear skies over the Corn Belt. High pressure will be at the surface with forecast soundings indcating a very dry airmass. Highs today will be in the upper 30s to mid 40s, while lows tonight bottom out in the lower to mid 20s.
an upper level ridge axis currently over the area this morning will slowly move east-southeast as an upper level trough and its cold front approach. A few 60 degree readings cant be ruled out from Hill City to Tribune and Leoti south based on 850mb temperatures and the warmer MAV guidance. Low temperatures tonight fall into the lower to upper 20s. an upper level trough and its associated cold front move through during the day, producing some breezy northwest winds and cooler daytime temperatures in the 41 to 52 degree range. Low temperatures are forecast to be in the lower to middle 20s.
Continued to trend towards the warmer side of guidance with afternoon high temps in the mid to upper 80s.
A low amplitude ridge of high pressure will be over the Northern Rockies this weekend. This ridge will allow for the development of weak valley inversions.
(Today through Sunday afternoon) Great weather is expected by Sunday as an upper ridge builds into our area. The only real target of opportunity will be Sunday afternoon where MOS guidance is warmer than NBM, so have pulled temps up a tad. Mid- upper level clouds ahead of the next trough may complicate this some, otherwise expect a rather beautiful day for Super Bowl Sunday.
