300 AM CST Sat Mar 4 2023 (Issued 300 AM CST Sat Mar 4 2023) Today through Tonight: Surface ridging along with mainly clear skies has resulted in some patchy fog development.
Expect partly to mostly cloudy skies with highs in the upper 30s and low to mid 40s, and lows tonight falling into the low to mid 30s.
High pressure and increasing subsidence aloft will provide dry weather and lessening winds this afternoon and tonight.
1050 PM EST Fri Mar 3 2023 Conditions improve quickly tonight as a cold front sweeps through the forecast area. The front will shift off the coast by Saturday morning with cooler and drier air settling over the region for the weekend.
1001 PM MST Fri Mar 3 2023 Snow rates will decrease across western Wyoming this afternoon and evening as the trough axis begins moving off to the east. Currently, a weak cold front is beginning to push down into northern Wyoming. The front will stall east of the Divide tonight as a brief transitory ridge builds in.
258 AM EST Sat Mar 4 2023 Gusty winds persist this morning before weakening today as high pressure arrives.
Currently partly cloudy and dry with flat upper ridge over our CWA. Ridge will shift east to WY overnight and Saturday morning as the next upper trough off the northwest coast becomes a closed low.
Winds have gone calm across the region and will slowly become out of the south as a high pressure center moves into Louisiana. South flow will increase today in response to a weak low pressure system moving into Western Central Texas this afternoon. The low will fill and get absorbed into the mean flow tonight as stronger height falls overspread the Central Plains and induce cyclogenesis near Denver.
1203 AM CST Sat Mar 4 2023 Gradient remains tight over South Texas in the wake of the exiting low pressure system currently moving into Southern Illinois and winds have been gusting higher than guidance indicates. Winds should relax sharply by noon as high pressure settles into the region revealing a very nice day across South Texas with low humidities and mild/warm temperatures with highs in the upper 70s east to mid 80s west. Surface winds have dropped to less than 10 knots most areas as the ridge axis settles along the coast. Winds will become onshore late this afternoon and early evening as the ridge axis shifts east. Warm and dry conditions can be expected Saturday with highs in the 80s as a flat ridge persists aloft.
102 AM EST Sat Mar 4 2023 A very strong low pressure system will track through the area this evening and continue off to the east overnight. High pressure will build in Saturday and persist through the weekend.
Attention then turns to upper low off the OR/CA coast.
On tap for today, the upper level low pressure associated with the aforementioned front slides east and across the Northeast.
The low clouds and fog will mix out late in the morning to midday on Sunday.
With moisture beginning to increase Sunday, increased cloud cover could keep daytime highs a tad bit cooler than Saturday with highs topping out in near 87 across the western Brush Country and Rio Grande Plains.
The system is expected to bring light snow to the Sierra and the higher mountain peaks of the southern Great Basin with dry conditions elsewhere.
Highs will be cooler than normal. Models currently show low pressure just west of British Columbia, Canada in the eastern Pacific. The low pressure system is expected to stay put as showers continue across northern and central Nevada. Snow levels will drop to the valley floors during the overnight with general accumulations of one to three inches in the valleys with two to five inches on the higher passes and summits. For Sunday and Sunday night, the low pressure system is expected to remain off the coast of Washington and Oregon.
These mild temperatures this morning have been aided by the steady southwest flow in place ahead of a cold front that is slowly pushing southward through north Florida. While it will be breezy again today ahead of the cold front with some gusts over 25-30 mph at times, winds will not be quite as strong as yesterday. Latest regional radar imagery shows a narrow band of showers associated with the cold front in north Florida with PoPs increasing from north to south today across the CWA as the front slowly approaches our area, but the highest rain chances continue to remain north of I-4. On tap for today, the upper level low pressure associated with the aforementioned front slides east and across the Northeast.
416 AM EST Sat Mar 4 2023 Low pressure will move east of the region today with precipitation slowly coming to an end.
535 AM CST Sat Mar 4 2023 (Today through Sunday afternoon) A picture perfect day is in store with light winds, sunny skies, and high temperatures in the low to mid 70s. You can't beat that for early March in West TX! A swift moving shrtwv trough will pass through the Central Plains this morning, dropping a cold front southward to our region. This will keep overnight lows warmer to the east and slightly cooler out west where dewpoints remain in the teens. Everywhere should remain above the freezing mark besides the typical low spot at MRF. Highs will soar into the low to mid 80s across the eastern half of the region w/upper 70s elsewhere.
To start the period, water vapor satellite imagery shows a well defined broad upper trough in the Gulf of Alaska shifting southeastward. Generally westerly flow aloft will turn southwesterly as this broad trough shifts southeastward through the day today.
Another wave of low pressure will swing through tonight into Sunday. Any precipitation will be short lived and given it will arrive in the early evening with warmer air it is expected to be primarily rain.
132 AM PST Sat Mar 4 2023 After a few days of dry but cold weather, a trough will move into and begin impacting the area today through Sunday night.
551 AM CST Sat Mar 4 2023 (Today) A secondary cold front has moved southward through the TN Valley, bringing slightly cooler and drier air behind it. Skies are expected to mostly clear out after daybreak, allowing high temperatures to warm into the low to mid 60s this afternoon-- right around normal seasonal high temp values for this time of year.
542 AM CST Sat Mar 4 2023 Fog has developed early this morning over the area with the lowest visibilites in the river valleys. It will be noticeably warmer today with more sun and winds out of the southwest resulting in highs nearly 10 degrees above normal.
(Today and tonight) A cold front is expected to pass east of Valdosta and Cross City later this morning, taking the remaining showers and cloud cover with it. Lows tonight will be cooler, ranging from the upper 40s to upper 50s with mostly clear skies.
While forecast soundings show lift within the DGZ, temperatures in the surface to 4000ft layer are above freezing with max temperatures of 3-6 degrees Celsius.
416 AM EST Sat Mar 4 2023 Strong low pressure will track off to the east as high pressure builds into the area today. This high will offer dry conditions through the weekend.
649 AM EST Sat Mar 4 2023 (Today and tonight) A cold front is expected to pass east of Valdosta and Cross City later this morning, taking the remaining showers and cloud cover with it. Lows tonight will be cooler, ranging from the upper 40s to upper 50s with mostly clear skies.
Still expecting a much warmer and windy day on Sunday with highs well above seasonal climo.
517 AM CST Sat Mar 4 2023 Key Messages: - Warmer today with a chance for some sprinkles this morning into early afternoon.
Lows tonight will be a bit warmer than last night with temperatures in the upper 50s.
Northerly winds will continue across western Kansas this morning behind a weak cold front. An area of high pressure will trek north of the area today leading to winds to shift from the north this morning to a southerly direction by this evening. As for temperatures, highs today look to reach into the upper 50s to around 60 degrees with lows tonight ranging from around freezing across west central Kansas to around 40 degrees across south central Kansas.
Will note that areas with a lingering deeper snow- pack may struggle to get into the lower 40s, especially parts of northwest Indiana. This warming combined with the higher March sun angel should help melt most of the remaining snow on the ground. There are some questions regarding whether we saturate sufficiently which could keep rainfall rates on the lower-end, though there is enough consistency among the various suite of guidance to continue to message the potential for scattered showers to move through this afternoon into early evening.
(Today and tonight) Early morning West Texas and Oklahoma Mesonet analysis shows a cold front positioned east of Hooker, OK to near Stratford and southwest into New Mexico.
High pressure building over the Mississippi River Valley will lead to low humidity, light winds, clear skies, and pleasant temperatures for us. The high pressure slides eastward on Sunday with a weak low pressure system moving through the Northern Plains. This will bring a southerly flow across Texas bringing temperatures up a few degrees on Sunday in our area with most spots either hitting the low 80s or at least approaching 80 degrees.
Snow levels will rise up to 3000 ft today over the Sierra ahead of this first wave, but then lower this evening following cold front passage after 5pm, remaining below 2000ft through the event with significant snow down to many foothill communities.
637 AM EST Sat Mar 4 2023 Low pressure will move east of the region today with precipitation slowly coming to an end.
320 AM CST Sat Mar 4 2023 Today through tonight: Weak high pressure will build over the forecast area today and remain centered over the area through tonight resulting in dry weather and seasonable temperatures. Warmer than normal temperatures can be expected as highs range from the low 70s to low 80s.
630 AM EST Sat Mar 4 2023 Strong low pressure will track off to the east as high pressure builds into the area today. This high will offer dry conditions through the weekend.
952 AM EST Sat Mar 4 2023 Low pressure will strengthen while tracking along the coast of the middle Atlantic and southern New England this morning, during which time a trailing cold front will move east and off the coast of the Carolinas. Mild high pressure will follow and build across the middle Atlantic through the weekend. The dry downsloping winds and subsidence aloft will keep conditions warm and dry today, with highs in the low 60s N to low 70s S (5-10 deg abv normal). Even though relative humidity will be quite low and winds are gusty today, the winds should diminish by this afternoon when the relative humidity reaches the lowest values. Cool high pressure will sit over central NC Sun and Sun night.
Today through Sunday: High pressure is expected to build across the area through this time period before gradually shifting to the east Sunday afternoon. This will be ahead of the next area of low pressure drifting across the central Plains.
Upper level trough passing well north will push a wind shift towards the area from the west but will dissipate about the time it arrives into the area and will have little effect on actual weather. The warmer conditions will continue into tonight with overnight lows only in the 40s to near 50.
943 AM EST Sat Mar 4 2023 High pressure building into the area will offer dry conditions through the weekend.
405 AM EST Sat Mar 4 2023 Strong low pressure will track off to the east as high pressure builds into the area today. This high will offer dry conditions through the weekend.
540 AM CST Sat Mar 4 2023 (Today and tonight) Early morning West Texas and Oklahoma Mesonet analysis shows a cold front positioned east of Hooker, OK to near Stratford and southwest into New Mexico.
358 AM CST Sat Mar 4 2023 Fog has developed early this morning over the area with the lowest visibilites in the river valleys. It will be noticeably warmer today with more sun and winds out of the southwest resulting in highs nearly 10 degrees above normal.
Lingering vorticity advection and -6C 850mb temperature will support light snow and rain mixed for the first half of the day, gradually transitioning to rain as the lower levels warm west of the Laurels.
544 AM CST Sat Mar 4 2023 Today through tonight: Weak high pressure will build over the forecast area today and remain centered over the area through tonight resulting in dry weather and seasonable temperatures. Warmer than normal temperatures can be expected as highs range from the low 70s to low 80s.
(Today) A secondary cold front has moved southward through the TN Valley, bringing slightly cooler and drier air behind it. Skies are expected to mostly clear out after daybreak, allowing high temperatures to warm into the low to mid 60s this afternoon-- right around normal seasonal high temp values for this time of year.
Expect partly to mostly cloudy skies with highs in the upper 30s and low to mid 40s, and lows tonight falling into the low to mid 30s. Towards the late afternoon and early evening an upper level trough will shift into the area from the west, with a cold front at the surface. Lows will fall into the low to mid 30s. Lows Sunday night will range from the 30s into the low 40s.
(Today through Sunday) At long last, a reprieve from the active weather pattern has arrived as the last bit of the forecast area gets behind the leading edge of a cold front. High pressure will reign near the ground, with strong ridging around 850mb, but quasi-zonal flow aloft near 500mb which should keep afternoon high temperatures from getting too extreme, with the forecast calling in the 70s.
411 AM CST Sat Mar 4 2023 Key Messages: - Warmer today with a chance for some sprinkles this morning into early afternoon.
400 PM EST Sat Mar 4 2023 Mild high pressure will build across the middle Atlantic through the weekend. This, and heights building aloft from a weak ridge to our east, will continue dry weather and mostly clear skies.
101 PM EST Sat Mar 4 2023 High pressure with dry conditions and lighter winds takes hold.
226 PM CST Sat Mar 4 2023 A weak cold front continues to slide southeast into the region this afternoon. Patchy dense river fog is possible once again tonight due to light winds and moisture in the low levels, so added mention. Otherwise, rest of forecast area will be dry and mild with lows in the low to mid 50s, at least 20 degrees above normal.
This feature a sfc reflection of passing S/W trof aloft, and producing some light rain or sprinkles in spots. Water vapor imagery was indicating another upper level trof further upstream acrs CA that will stride inland and be another wx maker for Sunday night acrs the area. The above mentioned western upper trof will look to be organizing acrs the southwestern plains, while a warm frontal boundary sets up acrs the southern CWA by late in the day.
Temperatures and dewpoints are +20 degrees cooler/lower at this hour than yesterday as cooler and drier air filters in with temps currently sitting around 50 degrees and dewpoints around 40 degrees. We'll warm up into the lower 60s this afternoon which is seasonable for this time of year.
Cronce (Issued 300 AM CST Sat Mar 4 2023) Today through Tonight: Surface ridging along with mainly clear skies has resulted in some patchy fog development.
(Tonight) High pressure will continue to build into the region tonight, slacking north/northeasterly winds to below 5 kts.
The wind is gradually subsiding this afternoon as responsible low pressure propagates eastward, and the pressure gradient relaxes. High pressure will build in quickly afterward. Low temperature will be near to just above freezing overnight with mostly cloudy conditions.
1256 PM EST Sat Mar 4 2023 High pressure builds in this afternoon.
(This evening through Sunday) A zonal flow prevailed over much of the Deep South while a weak trough was moving east over the Mid-South Region. Drier air aloft will mix down with time through the afternoon, resulting in surface dew points falling into the lower 40s with time. The zonal flow pattern will continue aloft into the overnight hours while lower amplitude broad ridging builds aloft to our west. Broad ridging will continue to build further as it moves east over the area, extending to over much of the Ohio River Valley Region. Highs will range from the lower 70s far north and into the higher elevations east to readings in the upper 70s generally near and south of the U.
High pressure at the surface will continue to build into the region today, with flow aloft becoming more zonal. /19/ Today through tonight: Weak high pressure will build over the forecast area today and remain centered over the area through tonight resulting in dry weather and seasonable temperatures. Warmer than normal temperatures can be expected as highs range from the low 70s to low 80s.
This will keep overnight lows noticeably warmer than seen last night.
Near the surface, high pressure is shifting eastward through the Northern High Plains. A dry pattern continues throughout the period as a relatively zonal flow aloft remains in control across the Western High Plains tonight into Sunday, not to mention much drier air in the lower/mid levels dominating the region. The cooler air mass settled across the high plains of western Kansas will be reinforced by east-southeasterlies developing on the back side of departing high pressure. Developing lee side troughing will strengthen in eastern Colorado Sunday, bringing about southwesterly downsloping to the area and helping push H85 temperatures up around 15C or a little above by mid-afternoon.
Winds have steadily decreased through the day as mean layer ridging has shifted a little farther east, and combined with the above average temperatures and dewpoints hovering around 70 degrees, has led to quite a warm, muggy day. Ridging will continue to dominate our sensible weather even after being nudged southward by a frontal boundary currently draped across North Central Florida.
1222 PM EST Sat Mar 4 2023 The cold front is pretty much on top of Cross City this hour with a thin band of showers moving through this hour. (Today and tonight) A cold front is expected to pass east of Valdosta and Cross City later this morning, taking the remaining showers and cloud cover with it. Lows tonight will be cooler, ranging from the upper 40s to upper 50s with mostly clear skies.
1135 AM CST Sat Mar 4 2023 (Today and tonight) Early morning West Texas and Oklahoma Mesonet analysis shows a cold front positioned east of Hooker, OK to near Stratford and southwest into New Mexico.
This system will move over Ohio and continue eastward after midnight with upper ridging building in behind it. Confidence is growing on fog given a strong consistent signal in some of the high-res short range models. Lows will generally be in the mid/upper 30s with protected valley locations falling into the low 30s. Afternoon highs with plenty of sunshine will range from the low/mid 60s north of the Parkways to mid/upper 60s south towards the KY/TN border.
High Risk for Life-Threatening Rip Currents at all Central Weak cold front across north FL will continue to nudge southward before stalling near to just north of Lake and Volusia counties this afternoon. Otherwise, offshore flow will continue to gradually diminish as a weak cold front drops slowly southward and stalls this afternoon near to north of the Volusia County waters.
154 PM EST Sat Mar 4 2023 Mild high pressure will build across the middle Atlantic through the weekend. This, and heights building aloft from a weak ridge to our east, will continue dry weather and mostly clear skies.
Weak upper ridging begins to build across the region on Sunday with high pressure shifting east of the forecast area. This allows highs to climb into the low to upper 60s across most areas with plenty of sun expected through the day.
247 PM EST Sat Mar 4 2023 (This afternoon through Sunday) The cold front has passed and high pressure has settled into the area, bringing with it a beautiful next couple of days. Highs today and tomorrow will be in the low to mid 70s across the area, with mid 60s across much of northern GA. Overnight lows will be on the chilly side dipping down into the mid to low 40s with some high 30s in the higher elevations of the GA mountains. Light north winds will gradually become east to south east tomorrow as the center of the high pressure moves east and increasing in strength to 5-10 mph and gusting up to 20 mph.
This will help keep the metro's a touch cooler, but remaining above normal.
A weak cold front will edge into portions of northeast Oklahoma today with an increase in mid-level clouds near the boundary.
116 PM MST Sat Mar 4 2023 Water vapor shows large upper low/trof just offshore the Pac NW with ejecting wave per baroclinic leaf signature shifting northeast into the Central Rockies. Transient ridge is located over the Northern Plains, bringing plenty of sunshine early this afternoon.
350 PM EST Sat Mar 4 2023 Clouds will increase again later tonight and early Sunday with a weak cold front. High pressure will quickly build in Sunday, with clearing skies and warming temperature for the rest of this weekend. Stratocu continues to erode as subsidence increases under building high pressure, and as the wind backs to the southwest.
At the same time, another large upper trough moving into the Pacific northwest will help to induce surface lee cyclogenesis over the High Plains. Daytime high temperatures should warm well into the 70s areawide and possibly into the lower 80s in Deep East Texas eastward into Central Louisiana.
(Tonight through Sunday night) High pressure is spreading over the County Warning Area and the result through Sunday night will be dry, seasonal weather with light winds, mostly clear skies and near normal temps.
212 PM CST Sat Mar 4 2023 A ridge of high pressure sits under zonal flow aloft yielding a sunny and mild day with highs stretching towards 60 degrees.
(This afternoon through Sunday Night) Dry conditions will prevail through Sunday night due to ridging influences surface and aloft.
The airmass remains dry through the lowest 10-15kft which will keep dry conditions across the region as the disturbance passes with the exception of a few sprinkles over the northern Wabash Valley early this evening. Skies should clear quickly from the west as the evening progresses with ridging aloft and at the surface reestablishing overnight. Sunday looks outstanding as winds veer around to an E/SE direction with the high pressure ridge passing through the area.
Temperatures this afternoon are mainly in the mid to upper 70s except in the northern Big Country were they're a touch cooler. It'll be even warmer tomorrow and breezier as south-southwest winds increase in the afternoon.
Warmer temperatures are also expected Sunday with highs expected to climb into the mid 70s (east fa) to low/mid 80s (west fa).
130 PM EST Sat Mar 4 2023 High pressure builds in this afternoon.
Temperatures will continue to remain cooler than normal for early March. Current satellite imagery shows a low pressure system spinning off the coast of British Columbia/Pacific Northwest. The Owens Valley and southern Great Basin will also see increased precipitation chances this evening into Sunday, with the highest accumulations expected in the panhandle of Lincoln County and a dusting elsewhere.
Temperatures are on track to reach the 80s for all but coastal areas where SSTs in the upper 60s will limit air temps to the lower 70s. With moisture beginning to increase Sunday, increased cloud cover could keep daytime highs a tad bit cooler than Saturday with highs topping out in near 87 across the western Brush Country and Rio Grande Plains.
1126 AM CST Sat Mar 4 2023 Key Messages: - Warmer today with a chance for some sprinkles this morning into early afternoon.
1017 AM EST Sat Mar 4 2023 The cold front is pretty much on top of Cross City this hour with a thin band of showers moving through this hour. (Today and tonight) A cold front is expected to pass east of Valdosta and Cross City later this morning, taking the remaining showers and cloud cover with it. Lows tonight will be cooler, ranging from the upper 40s to upper 50s with mostly clear skies.
