(This evening through Wednesday night) A lovely Tuesday afternoon with partly to mostly cloudy skies with temperatures into the lower 60s. Going forward into tonight, cloud cover is expected to increase out ahead of the main H500 trough axis over SoCal with good mid and upper level moisture transport into the region. Pronounced H500 height gradient will be in place across the southern High Plains tomorrow as the main H500 trough traverses the southwest CONUS tomorrow.
(Tomorrow through Tuesday) Large scale trough will become established over the western U.
Residual clouds on the back side of this low have moved over southeast Florida allowing for sunny skies across west central and southwest Florida. Breezy northerly winds behind this low will filter in some cooler and drier air on Tuesday and Wednesday nights with overnight lows dipping into the 30's and 40's.
523 PM CST Tue Feb 6 2024 High pressure will bring quiet weather to the Mid-South through Wednesday.
(This afternoon through Wednesday) Low pressure off the east coast will continue to move out to sea. High pressure, currently stretching from the central Great Lakes back through central TX, will move east overnight. Ridging will remain overhead for tomorrow and tomorrow night.
A mild overnight is anticipated with the well mixed boundary layer maintaining the temperature fairly homogeneously in the low to mid 40s across the area.
542 PM PST Tue Feb 6 2024 Temperatures will gradually trend cooler into the weekend.
Increasing surface winds overnight will keep overnight temperatures quite warm for this time of the year with lows forecast in the low 40s, which would be record warm minimums. The upper level pattern flattens out as we head into the weekend with cooler air (still above normal) filtering south across the area. Lows will dip below freezing but highs will remain above freezing through the period.
523 PM CST Tue Feb 6 2024 (This evening through Wednesday night) A lovely Tuesday afternoon with partly to mostly cloudy skies with temperatures into the lower 60s. Going forward into tonight, cloud cover is expected to increase out ahead of the main H500 trough axis over SoCal with good mid and upper level moisture transport into the region. Pronounced H500 height gradient will be in place across the southern High Plains tomorrow as the main H500 trough traverses the southwest CONUS tomorrow.
A broad upper trough over CA will push east into the Great Basin into Wednesday. There will be ample forcing but limited CAPE making it over land as the trough and associated occluded frontal boundary dives SE and clips our CWA.
455 PM CST Tue Feb 6 2024 (This evening through Wednesday) Short wave ridging over the area today will transition to southwest flow aloft tonight and Wednesday, in advance of an upper level trough moving into the Desert Southwest. Lows tonight will be in the low to mid 40s. Lee trough develops on Wednesday, resulting in breezy south winds, with afternoon highs in the mid and upper 60s.
738 PM CST Tue Feb 6 2024 (Tonight through Wednesday night) High pressure over the Coastal Bend is continuing the light and variable winds, with mild temperatures. The ridge will continue to the east tonight, and begin to push the winds more from the southeast (onshore).
There is a 70% chance for widespread dense fog to redevelop; and a 20% chance of freezing drizzle dependent upon temperatures dipping below freezing.
Some locations may trend cooler if winds become lighter than forecast since skies will be clear. Regardless, min apparent temperatures are slated to be near or just below freezing. A high pressure system will move over in the Carolinas, causing winds to turn northeasterly tomorrow morning, with temperatures staying in the mid-to-low 60s throughout the day under mostly sunny skies.
323 PM CST Tue Feb 6 2024 - Dense fog expected to return and freezing drizzle possible late tonight through tomorrow morning.
Factoring in the wind chill, these temperatures will feel a a few degrees cooler.
(Tonight) With high pressure overhead, expect another clear and cool night across the Tennessee Valley. With ideal radiational cooling conditions overnight, lows bottom out in the lower 30s.
517 PM CST Tue Feb 6 2024 (This afternoon through Wednesday Night) It's another beautiful albeit cooler day across Middle Tennessee today with temperatures ranging from the mid 40s in the northeast up to around 60 in the southwest. Tomorrow will be another spectacular and warmer day with highs rising 30 to 40 degrees from morning lows, reaching the 60s areawide. Cirrus clouds will begin increasing/thickening through the day ahead of our next storm system, with strengthening WAA on Wednesday night leading to much warmer lows in the upper 30s to mid 40s.
(Tonight through Wednesday night) High pressure over the Coastal Bend is continuing the light and variable winds, with mild temperatures. The ridge will continue to the east tonight, and begin to push the winds more from the southeast (onshore).
707 PM EST Tue Feb 6 2024 High pressure will build across the East Coast as a strong storm system slowly departs out to sea, allowing winds to subside. High pressure will build down across the entire east coast with a very high amplitude ridge shifting east through Wednesday as strong storm system lifts slowly east-northeast farther out into the Atlantic. Temps will drop in continued CAA with overnight lows down below freezing most places.
Other than the breezy conditions developing on Wednesday, clouds will be on the increase overnight tonight into Wednesday as the aforementioned low pressure system moves into closer proximity to the region. Despite the increase in cloud coverage, warm air advection (WAA) should be enough to aid in temperatures climbing to warmer than normal levels on Wednesday with values ranging from the mid 70s to the low-mid 80s over much of Deep South Texas on Wednesday (lower 70s coastal areas and along South Padre Island).
232 PM MST Tue Feb 6 2024 Areas of dense freezing fog have persisted across the area today, leading to an expansion of the Dense Fog Advisory through 00z Wednesday. Next, ensembles continue to show a variety of mixed precipitation and freezing rain on Wednesday, extending into the afternoon and early evening hours.
718 PM EST Tue Feb 6 2024 A deep low pressure system well offshore of South Carolina will track northeast away from the region as high pressure builds in from the north.
519 PM CST Tue Feb 6 2024 (This evening through Wednesday night) Rather amplified upper pattern this afternoon with upper lows over the Bahamas and near Los Angeles. In between, an amplified ridge from Texas into the Great Lakes. Similarly, at the surface, high pressure extended from Texas to the Great Lakes.
616 PM CST Tue Feb 6 2024 (This evening through Wednesday Night) High cirrus clouds will be on the increase tonight and Wednesday as an upper-level ridge translates east across the forecast area brining southwesterly flow aloft back to the region by Wednesday evening.
A large, high amplitude ridge sits to our west, producing a dry northerly flow over the area. Most places will fall near to below freezing overnight.
458 PM CST Tue Feb 6 2024 (This evening through Wednesday) As the ridge (overhead) and the long-wave trough (western US) shift eastward tonight, mid/upper-level flow backs to the southwest and the strong jet stream (Baja to desert southwest) overspreads our region on Wednesday.
Taking a look at the slightly warmer than forecasted high temps from today, and the continued dry, cool air mass in place for tonight, have nudged the lows slightly cooler and the highs for Wednesday slightly higher. Sightly cooler than normal tonight and then warmer than normal Wednesday. Mid afternoon surface analysis had a north-south oriented 1022mb ridge just to our west. Mid afternoon satellite imagery/RAP analysis showed a north- south oriented mid level ridge axis just to our west as well. As the mid level ridge axis shifts east wl see a gradual increase of high level clouds.
(This evening through Wednesday night) Rather amplified upper pattern this afternoon with upper lows over the Bahamas and near Los Angeles. In between, an amplified ridge from Texas into the Great Lakes. Similarly, at the surface, high pressure extended from Texas to the Great Lakes.
642 PM EST Tue Feb 6 2024 Dry and mild high pressure will dominate our weather through most of the work week.
545 PM CST Tue Feb 6 2024 (This afternoon through Wednesday) Skies are clear and sunny across the Southeast this afternoon amidst a broad region of high pressure extending from the Ohio Valley southwest into the ArkLaTex. Temperature and dewpoint trends have been favoring the outlier solutions with temperatures trending warmer than forecast and dewpoints trending lower.
(This evening through Wednesday) As the ridge (overhead) and the long-wave trough (western US) shift eastward tonight, mid/upper-level flow backs to the southwest and the strong jet stream (Baja to desert southwest) overspreads our region on Wednesday.
958 PM EST Tue Feb 6 2024 High pressure will build across the East Coast as a strong storm system slowly departs out to sea, allowing winds to subside. High pressure will build down across the entire east coast with a very high amplitude ridge shifting east through Wednesday as strong storm system lifts slowly east-northeast farther out into the Atlantic. Temps will drop in continued CAA with overnight lows down below freezing most places.
400 AM EST Wed Feb 7 2024 High pressure will build across the eastern half of the United States through the end of the week. Another day with mostly clear skies (canât rule out a few high cirrus clouds late in the day) across the region as upper level ridge builds east across the Eastern US.
1004 PM EST Tue Feb 6 2024 Dry and mild high pressure will dominate our weather through most of the work week.
901 PM MST Tue Feb 6 2024 An upper trough closing off over eastern Montana Wednesday will continue to spread precip NE into the CWA through Wednesday. With temps below freezing across the northern zones, thought of starting it earlier, but it's mainly dry and 4 am start time looks good. TFJ Areas of dense freezing fog have persisted across the area today, leading to an expansion of the Dense Fog Advisory through 00z Wednesday. Next, ensembles continue to show a variety of mixed precipitation and freezing rain on Wednesday, extending into the afternoon and early evening hours.
330 AM EST Wed Feb 7 2024 Fair weather and moderating temperatures are expected through Thursday as high pressure remains nearby.
(Today) High pressure and ridging at all levels will shift east through the TN valley today.
1210 AM EST Wed Feb 7 2024 High pressure maintains dry weather through Thursday.
243 AM EST Wed Feb 7 2024 High pressure will continue to bring quiet weather to the area through Thursday.
343 AM EST Wed Feb 7 2024 Low pressure offshore of the east coast lifts out today as high pressure builds down the state.
1050 PM CST Tue Feb 6 2024 (This evening through Wednesday) Short wave ridging over the area today will transition to southwest flow aloft tonight and Wednesday, in advance of an upper level trough moving into the Desert Southwest. Lows tonight will be in the low to mid 40s. Lee trough develops on Wednesday, resulting in breezy south winds, with afternoon highs in the mid and upper 60s.
1113 PM CST Tue Feb 6 2024 Taking a look at the slightly warmer than forecasted high temps from today, and the continued dry, cool air mass in place for tonight, have nudged the lows slightly cooler and the highs for Wednesday slightly higher. Sightly cooler than normal tonight and then warmer than normal Wednesday. Mid afternoon surface analysis had a north-south oriented 1022mb ridge just to our west. Mid afternoon satellite imagery/RAP analysis showed a north- south oriented mid level ridge axis just to our west as well. As the mid level ridge axis shifts east wl see a gradual increase of high level clouds.
As a result, we should see high temperatures a few degrees warmer (lower 70s) and low temperatures much warmer (high 50s to low 60s) as building cloud cover and WAA inhibit radiative cooling.
Wednesday night through Thursday morning trends even warmer in the 50s with the increased low level clouds and moisture.
1222 AM EST Wed Feb 7 2024 Dry and mild high pressure will dominate our weather through most of the work week.
1113 PM CST Tue Feb 6 2024 (This afternoon through Wednesday) Skies are clear and sunny across the Southeast this afternoon amidst a broad region of high pressure extending from the Ohio Valley southwest into the ArkLaTex. Temperature and dewpoint trends have been favoring the outlier solutions with temperatures trending warmer than forecast and dewpoints trending lower.
The highest gusts continue along the coast, where a Wind Advisory remains in effect until 1 AM.
1002 PM PST Tue Feb 6 2024 Temperatures will gradually trend cooler into the weekend.
(Today and tonight) Southwest upper flow is expected to develop across the region today as broad upper trough shifts east a bit with an impulse(s) moving through the flow.
325 AM EST Wed Feb 7 2024 High pressure maintains dry weather through Thursday.
132 AM EST Wed Feb 7 2024 High pressure will bring fair weather through Thursday.
(Today through Thursday Night) Another dry day is expected this Wed as an upper ridge moves east over the state. The upper ridge will have shifted east by this evening.
ARS High pressure will bring quiet weather to the Mid-South through Wednesday. Gusty winds will develop Thursday ahead of a cold front. The cold front will sag into the area late this week into the weekend resulting in unsettled weather and elevated chances for showers and thunderstorms.
- Windy and cooler Thursday behind a cold front. Any light accumulations favor the Pine Ridge in northern Sheridan County. A closed upper low will develop over the Dakotas Wednesday night as the upper trough axis moves across western NE and a cold front moves through most of the area. The GFS and ECMWF indicate the closed low will remain across eastern North Dakota into northwest Minnesota on Thursday, with H5 height rises across Nebraska. Any snow accumulation should be limited to the far northwest near the Pine Ridge where up to a half inch is possible.
352 AM EST Wed Feb 7 2024 High pressure builds in from the north today. A period of dry weather follows with warmer temperatures expected Thursday into the weekend.
Later today the upper ridge shifts further east and the low level flow becomes southerly across our area.
Warmer southwesterly flow and southerly surface winds and an amplifying upper-level ridge will help temperatures get up near 60 degrees this afternoon despite the cloud cover.
1222 AM EST Wed Feb 7 2024 High pressure will continue to bring quiet weather to the area through Thursday.
1124 PM CST Tue Feb 6 2024 (This evening through Wednesday night) Rather amplified upper pattern this afternoon with upper lows over the Bahamas and near Los Angeles. In between, an amplified ridge from Texas into the Great Lakes. Similarly, at the surface, high pressure extended from Texas to the Great Lakes. Didn't make significant deviations from NBM forecast lows, but if there would need to be an adjustment, it would be slightly cooler tonight. Considering that we are outperforming guidance today, and forecast soundings indicate slightly warmer low level temperatures tomorrow, adjusted NBM deterministic highs up a degree or two.
235 AM EST Wed Feb 7 2024 High pressure over the eastern United States will provide fair dry weather through Thursday.
(Today and tonight) A plume of mid and high level moisture continues to stream across the forecast area this morning ahead of an approaching upper-level trough. Despite this cloud cover, temperatures will still be able to warm nicely today into the low to mid 60s as southerly to southwesterly surface winds increase in response to a tightening pressure gradient. Temperatures will be slightly cooler behind the front tonight in the mid 30s to mid 40s but still generally above average for this time of year.
A band of light to moderate rain and snow has developed primarily along the northwest flank of the low, stretching from far SW Idaho through the Upper Treasure Valley and into the Sawtooth Mountains. Snow levels will fall to 3000-4000 feet by Wednesday morning as cooler air moves in behind the low, but precipitation will start to taper off with little to no snow accumulation expected in the Snake River Valley. A longwave upper trough remains over the western US through Thursday.
304 AM EST Wed Feb 7 2024 High pressure will continue to bring quiet weather to the area through Thursday.
1037 PM CST Tue Feb 6 2024 (Tonight through Wednesday night) High pressure over the Coastal Bend is continuing the light and variable winds, with mild temperatures. The ridge will continue to the east tonight, and begin to push the winds more from the southeast (onshore).
346 AM EST Wed Feb 7 2024 High pressure will build across the eastern half of the United States through the end of the week. As the high pressure builds over western NC by 12z/Wed. As of Wednesday morning, high pressure will be centered over southern Quebec with a ridge extending along much of the east coast of the United States. The high pressure center and ridge will remain nearly stationary Wednesday and Wednesday night.
1225 AM EST Wed Feb 7 2024 High pressure will build across the East Coast as a strong storm system slowly departs out to sea, allowing winds to subside. High pressure will build down across the entire east coast with a very high amplitude ridge shifting east through Wednesday as strong storm system lifts slowly east-northeast farther out into the Atlantic. Temps will drop in continued CAA with overnight lows down below freezing most places. Not unlike Wednesday night a light breeze will persist through Thursday night, but being southerly the lows will be more seasonable.
1036 PM CST Tue Feb 6 2024 (This evening through Wednesday) As the ridge (overhead) and the long-wave trough (western US) shift eastward tonight, mid/upper-level flow backs to the southwest and the strong jet stream (Baja to desert southwest) overspreads our region on Wednesday.
1050 PM CST Tue Feb 6 2024 (This afternoon through Wednesday Night) It's another beautiful albeit cooler day across Middle Tennessee today with temperatures ranging from the mid 40s in the northeast up to around 60 in the southwest. Tomorrow will be another spectacular and warmer day with highs rising 30 to 40 degrees from morning lows, reaching the 60s areawide. Cirrus clouds will begin increasing/thickening through the day ahead of our next storm system, with strengthening WAA on Wednesday night leading to much warmer lows in the upper 30s to mid 40s.
Some locations may trend cooler if winds become lighter than forecast since skies will be clear. Regardless, min apparent temperatures are slated to be near or just below freezing. A high pressure system will move over in the Carolinas, causing winds to turn northeasterly tomorrow morning, with temperatures staying in the mid-to-low 60s throughout the day under mostly sunny skies. Warmer temperatures return to the region Thursday and beyond as the high slides into the Atlantic Ocean. Rain chances will remain out of the forecast thanks to an H5 ridge overhead.
1234 AM EST Wed Feb 7 2024 High pressure over the eastern United States will provide fair dry weather through Thursday.
A trough of low pressure will move eastward into the Great Basin today. An upper-level area of low pressure will dive southward across Central California tonight. This cyclone aloft will progress eastward into the Great Basin Thursday morning.
1053 PM CST Tue Feb 6 2024 (Tonight) With high pressure overhead, expect another clear and cool night across the Tennessee Valley. With ideal radiational cooling conditions overnight, lows bottom out in the lower 30s. (Wednesday through Thursday Night) The upper ridge axis will remain in place on Wednesday, with similar conditions forecast for tomorrow. A slightly cooler air mass noted on the leeside of the Appalachians may advect into those area, resulting in highs running a degree or two lower than today in some locations. In general though, highs in the low to mid 60s will once again be common across the area. As the upper ridge axis pivots eastward into the Carolinas, our flow will veer to a south to southwesterly direction on Thursday.
(Today through Thursday) As the vertically stacked low continues to push further offshore over the Atlantic and ridging over the Gulf of Mexico approaches the area, mid-level heights will rise noticeably today across South Florida. will continue to result in breezy N-NE winds, although speeds will be less than yesterday as the influence of the low wanes. On Thursday, the ridge will continue to build over the area resulting in dry conditions and mostly clear skies. Surface winds will lighten and turn NE/E as high pressure shifts over the Atlantic. Under mostly clear skies, highs will run just below seasonal normals today, largely in the low to mid 70s. Tonight's lows will be a bit warmer than the past few nights, with upper 40s to low 50s over the interior, and upper 50s to low 60s along the coast.
Satellite imagery early this morning shows a low pressure circulation moving south to north over southeastern Idaho. As this midlevel low spins up and moves north and east, it will gain strength and eventually mature into a midlatitude cyclone. The low is on track to continue its trajectory north, pulling moisture up from the south resulting in snow, or a rain- snow mix below about 4000 feet MSL. Areas of northwest Montana just west of the Continental Divide will benefit from moisture wrapping around the low and riding over the Divide. As todayâs low pressure moves east by Thursday morning, a second disturbance digs south into northern California. Upper level flow turns northerly behind the departing trough, bringing colder air with it for later in the week.
225 AM MST Wed Feb 7 2024 An upper trough closing off over eastern Montana today will continue to spread mixed precipitation NE across the forecast area today. While the low moves to the east tonight and Thursday, a trough axis across eastern Montana will keep the precipitation in the form of snow going until Thursday night.
This trough is expected to send a weak mid level disturbance across the area that will combine with the increased available moisture courtesy of a strengthening low- level onshore flow to spark a few showers over eastern portions of the CWA from late tonight through Thursday (PoPs <20%).
643 AM EST Wed Feb 7 2024 High pressure over the eastern United States will provide fair dry weather through Thursday.
452 AM CST Wed Feb 7 2024 (Today) High pressure and ridging at all levels will shift east through the TN valley today.
Surface and upper-level ridging will continue to bring rain free weather to the Mid-South through tonight. Shower and thunderstorm chances will gradually increase Thursday afternoon into the upcoming weekend as a cold front moves into the Mid-South and becomes nearly stationary.
Freezing fog may cause slick spots on untreated roads this morning.
539 AM CST Wed Feb 7 2024 (Today and tonight) Southwest upper flow is expected to develop across the region today as broad upper trough shifts east a bit with an impulse(s) moving through the flow.
318 AM CST Wed Feb 7 2024 - Warm front today means a contrast in temperatures across the state, with readings topping out in the 50s to those struggling to climb above 40 degrees. Inverted trough will become a warm front as it lifts north and west today, shifting the low clouds and fog into North Dakota and north central South Dakota. For highs today, there will be a sharp contrast along that front, somewhere between Aberdeen/Pierre and Mobridge. Otherwise, increasing low level flow ahead of developing low pressure will result in strong south winds for the Coteau region. Profiles support drizzle under the low as outside of the brief period of saturation aloft for light showers, but the mean 24 hour QPF is only around a tenth or two.
