1139 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.
This low will gradually become absorbed into the mean pattern later this evening, but not before an ill defined dryline pushes toward the I-35 corridor. Light winds and clear skies will foster another night of good radiational cooling, although it'll be a tad warmer than last night. Otherwise, Sunday will feature increasing southerly winds in response to a deepening surface cyclone over eastern Colorado. Steady south winds into Sunday night will lead to a warmer night with readings in the mid to upper 50s.
346 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.
Temperatures across the island chain have already reached the lower 80s and dewpoints are around 70 degrees. A mean layer ridge centered north of Hispaniola is still dominating our weather, and will continue to act as a blockade to this approaching front today.
1104 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.
Winds becoming W-SW after 05/06z with gusts 25-35 kt along a cold front.
Southwest flow aloft will turn more zonal through the weekend as an upper ridge moves over the Midwest and into the Great Lakes region. At the surface, high pressure extending from southwestern Louisiana and over Missouri will gradually shift east through the weekend. Along with drier air will come cooler air due to cold air advection from northwest flow. This will result in some cooler temperatures today, with highs forecast to top out in the lower to mid 70s northwest of I-65. Meanwhile, it will likely be warmer along and east of I-65 as highs in the mid to upper 70s are expected. Lastly, the High Surf Advisory that was issued for our Alabama and western Florida Panhandle coasts will expire at 6 AM CST, as surf heights continue to decrease. However, the HIGH RISK of rip currents will continue through Sunday night.
351 PM EST Sat Mar 4 2023 A weak trough of low pressure will move into the area tonight but high pressure returns on Sunday.
(This afternoon through Sunday night) A weak cold front has indeed moved into the Permian Basin and southeastern New Mexico this afternoon bringing a light north to northeasterly wind shift.
1126 AM CST Sat Mar 4 2023 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.
103 PM EST Sat Mar 4 2023 High pressure building into the area will offer dry conditions through the weekend.
Daytime high temperatures ranged from the low to mid 80s throughout the Keys, with light to gentle winds. The shifting of the high pressure will cause moisture to oscillate into the island chain periodically. A weakening frontal boundary over central Florida and high pressure over Key West will cause light to gentle breezes tonight. High pressure will slide back over the island chain on Sunday and will persist through the middle of the work-week. The high will promote light to gentle northeast to east breezes through the middle of the week. By the end of the week, high pressure will build in behind a weak front, leading to freshening breezes.
435 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.
Then Sunday night a cold front will move through the area and winds will pick back up.
Otherwise, look for high temperatures to be cooler than normal.
High pressure at the surface will continue to build east through the region through Sunday afternoon. Winds on Sunday will become more east and eventually southeasterly through the day, as highs range from the lower 70s to around 80.
646 PM EST Sat Mar 4 2023 A weak trough of low pressure will move into the area tonight but high pressure returns on Sunday.
(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.
627 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.
924 PM EST Sat Mar 4 2023 Clouds will increase tonight and early Sunday with a weak cold front. High pressure will then quickly build in Sunday, with clearing skies and warming temperature for the rest of this weekend.
505 PM CST Sat Mar 4 2023 (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.
644 PM EST Sat Mar 4 2023 High pressure builds in this afternoon.
515 PM CST Sat Mar 4 2023 (This afternoon through Sunday Night) Dry conditions will prevail through Sunday night due to ridging influences surface and aloft.
(Tonight through Sunday night) Key Messages: - Warm dry weekend with light winds - Fog Expected Tonight and Possible Sunday Night Weak surface ridging will remain in place over South Texas tonight. The next upper trough will move from the northern Rockies into the northern plains on Sunday.
949 PM EST Sat Mar 4 2023 A weak trough of low pressure will move into the area tonight but high pressure returns on Sunday.
522 PM CST Sat Mar 4 2023 (This afternoon through Sunday night) A weak cold front has indeed moved into the Permian Basin and southeastern New Mexico this afternoon bringing a light north to northeasterly wind shift.

750 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.
A ridge of high pressure sits under zonal flow aloft yielding a sunny and mild day with highs stretching towards 60 degrees.
852 PM EST Sat Mar 4 2023 Precipitation associated with prefrontal trough has sunk south of the region.
Global models keep the track of the low off to our south as it moves from west to east, while some of the convection allowing models (CAMs) shift the low to our north, resulting in a fairly wide range in solutions considering this is only 24 hours out. If we are correct in ruling out the CAMs, this transition to rain might not occur as the warmer (above freezing) air would remain south, which would increase our snowfall totals an additional inch or two higher than we are advertising. For now, expect less than half an inch south of I-90, with amounts getting close to an inch along the highway 14 corridor, while areas near Marshall, MN could see up to 2".
600 PM CST Sat Mar 4 2023 (Tonight) High pressure will continue to build into the region tonight, slacking north/northeasterly winds to below 5 kts.
146 PM PST Sat Mar 4 2023 Cooler and cloudier conditions are expected this weekend, with periods of drizzle and light rain at times.
A deep cold upper level trough is positioned offshore of WA this afternoon. However, a second area of low pressure will approach the area this evening/overnight bringing another round of precipitation to the region. Some high resolution guidance indicates snow may develop on the north side of this low all the way to sea level.
547 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.
Clear skies overnight with lows in the upper 30s for the Plateau to the lower 40s along the Tennessee River. Based on the fact the growing season has started have included some patchy frost around day break for the higher elevation sheltered locations. (This afternoon through Sunday Night) Dry conditions will prevail through Sunday night due to ridging influences surface and aloft.
630 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.
The forecast is tracking along nicely and the weather is tranquil as high pressure begins to build in. 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.
It is notable that some of the higher resolution models are diverging from some of the global ensembles, lending to reduced forecast certainty even at short time scales.
Temperatures this afternoon are mainly in the mid to upper 70s except in the northern Big Country were they're a touch cooler.
A cold air mass and low pressure system will bring rain, additional accumulating snow to the mountains, including periodically gusty west to southwest winds tonight and Sunday morning.
(Rest of tonight) Seasonably strong westerly flow aloft will continue across the TN Valley overnight, as our region remains along the northern rim of a flat subtropical ridge centered north of the Greater Antilles.
Temperatures this afternoon will reach the lower to mid 80s for highs across our area.
1058 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.
118 AM EST Sun Mar 5 2023 High pressure builds in this afternoon.
(Today and tonight) Key Message: Another quiet weather day expected, with temperatures a bit warmer than yesterday. Another pleasant day is in store with temperatures expected to climb a few degrees warmer than Saturday with a bit more sunshine present.
1237 AM PST Sun Mar 5 2023 A trough of low pressure will pass eastward across Central California today into tonight, resulting in snow in the Sierra Nevada and adjacent foothills, as well as periods of rain in the San Joaquin Valley.
Breezy conditions in the high country will hang on overnight, then intensify and expand into the arid lands of the Colorado Plateau after daybreak. Higher gusts are likely in locations immediately northeast of the highest terrain. Areas downwind of the higher terrain (like Doney Park) can expect winds to be quite gusty through the overnight hours.
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.
111 AM EST Sun Mar 5 2023 Clouds will increase tonight and early Sunday with a weak cold front. High pressure will then quickly build in Sunday, with clearing skies and warming temperature for the rest of this weekend.
358 AM EST Sun Mar 5 2023 A weak front will drop south through the area this morning with high pressure building in this afternoon.
122 AM EST Sun Mar 5 2023 A weak trough of low pressure will move into the area tonight but high pressure returns on Sunday.
138 AM EST Sun Mar 5 2023 A weakening cold front moves across northern Ohio into northwestern Pennsylvania through sunrise. High pressure builds over the region this afternoon but is quickly pushed eastward tonight.
241 AM CST Sun Mar 5 2023 After some early morning clouds in response to warm advection aloft, sunshine and a much warmer and windy day is on tap with increasing southerly surface flow to the east of the lee side trof.
(Today and tonight) Elongated upper trough will continue to move through the northern Rockies into the northern Plains today and tonight. These south to southwest winds will bring in a warmer airmass from the southwest across Oklahoma today. As the upper wave moves east into the Upper Midwest tonight a cold front will surge south in its wake, moving into northern Oklahoma overnight. This will mark the beginning of a much cooler week ahead.
1052 PM CST Sat Mar 4 2023 (This afternoon through Sunday night) A weak cold front has indeed moved into the Permian Basin and southeastern New Mexico this afternoon bringing a light north to northeasterly wind shift.
1029 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.
Today: High pressure over the area will gradually shift east this afternoon keeping quiet conditions in place. This will be ahead of the next area of low pressure drifting across the central Plains.
Fire weather concerns will be greatest west of highway 75 where afternoon RH values drop to 30 percent or just below, as temps soar well into the 70s to near 80 degrees and dewpoints drop into the low to mid 40s.
1053 PM CST Sat Mar 4 2023 Surface analysis had a ridge nearly along the I-55 corridor from the north. Under clear skies and a near calm wind temperatures will bottom out in the 40s which is rather cool but a couple degrees warmer than normal. High pressure at the surface will continue to build east through the region through Sunday afternoon. Winds on Sunday will become more east and eventually southeasterly through the day, as highs range from the lower 70s to around 80.
1017 PM MST Sat Mar 4 2023 The next snowstorm of this long winter is ongoing across western Wyoming as the first wave of a stronger Pacific trough arrives. Snow totals in the mountains this afternoon through Sunday afternoon will generally range from 6 to 12 inches, with the highest amounts in the Salt/Wyoming ranges. Totals across the lower Green River Basin and Sweetwater County are more difficult to pin down, as some of this snow will fall in bands tracking to the northeast across the area.
Surface analysis had a ridge nearly along the I-55 corridor from the north. Under clear skies and a near calm wind temperatures will bottom out in the 40s which is rather cool but a couple degrees warmer than normal. High pressure at the surface will continue to build east through the region through Sunday afternoon. Winds on Sunday will become more east and eventually southeasterly through the day, as highs range from the lower 70s to around 80.
1057 PM CST Sat Mar 4 2023 (Rest of tonight) Seasonably strong westerly flow aloft will continue across the TN Valley overnight, as our region remains along the northern rim of a flat subtropical ridge centered north of the Greater Antilles.
Some shadowing is evident in the lower Snake Basin, but radar shows more snow approaching and should add up to at least an inch overnight. Above-freezing temperatures at low-elevations this evening will limit accumulation to grassy surfaces but after midnight snow may stick on roads.
1027 PM CST Sat Mar 4 2023 (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.
The deep mean layer ridge continues shifting off to the east further into the western North Atlantic. However, an extension of this ridge stretches from the Bahamas west into the Gulf of Mexico. Generally quiet, dry, and warm weather is expected to continue for the Florida Keys through around mid-week as upper level ridging remains the dominant feature.
Ridging looks to take over the southern states on Monday.
As the system moves out models suggest some mixed precipitation could be possible across these northern portions, with a loss of ice also noted in model soundings suggesting a period of freezing rain could be possible for a time.
The prominent subtropical ridge that has been a fixture over the Gulf of Mexico for much of the cool season is forecast to rebuild after being temporarily suppressed. Temperatures this weekend have been closer to climatology, but a surface warm front will approach from the south, and the airmass will modify given plenty of sun.
Another system may near the area later in the week with gusty winds and cooler temperatures. A longwave positive tilt trough will remain over the western states but centered further north than we have seen in recent weeks.
644 AM EST Sun Mar 5 2023 A weak disturbance will bring a few rain or snow showers today before high pressure builds into the region late tonight and Monday.
404 AM CST Sun Mar 5 2023 Latest surface analysis was showing that the cold front has moved down to near I-70 at this hour with light winds across Missouri and Illinois. Highs today will climb into the lower-mid 60s as 850mb temperatures climb into the 5-10C range with a partly cloudy sky. A upper low over the Pacific Northwest will eventually move east this week, with the GFS digging a deeper trough over the Rockies by midweek compared to the more consistent ECMWF and Canadian which show a more progressive upper low moving across the Midwest late this week.
614 AM EST Sun Mar 5 2023 (Today and tonight) Key Message: Another quiet weather day expected, with temperatures a bit warmer than yesterday.
Water vapour loop had upper low west of WA/OR, which was spinning multiple waves into the northern Plains.
- Cold front slowly moves through tomorrow, with temperatures remaining above normal.
911 AM EST Sun Mar 5 2023 High pressure will prevail into tonight. A cold front approaches from the west on Monday and crosses the area Monday night, bringing a chance of a few showers late in the day into Monday evening. High pressure will then build in through midweek offering a period of dry weather. High pressure will predominate through the day. Broad mid level ridge to build over the region tonight with a warm front lifting north into the southern Great Lakes tonight. Expect mainly dry conditions but can not rule out a shower after 06Z across the far north closer to the warm front. Lows to range from the mid/upper 30s northeast to the lower 40s southwest. In WAA pattern have adjusted temperatures slightly above NBM with highs from the mid 60s north to the lower 70s south.
High pressure to the north will def impact the northward extent of snow, and should really start to have an influence tonight and especially Monday when dry air starts to dominate and shuns precip to our south. An upper level trough will remain quasi-stationary over the eastern Pacific/western CONUS, ejecting several embedded waves across the northern and central Rockies and into our region.
High temperatures this afternoon will climb into the low 80s for most the area with overnight lows tonight in the mid to upper 50s north of I-10 and low to mid 60s south of I-10. Temperatures on Monday will be in the low to mid 80s with overnight lows in the mid to upper 60s across most of the area.
This feature will provide another round of snow and wind for NE NV Sunday into Monday, while its parent long wave trough remains off shore. With the periods of snow and wind expect temperatures not to vary much and will range from the upper 20s to upper 30s for highs with lows dropping into the low single digits to the lower 20s.
550 AM CST Sun Mar 5 2023 (Today and tonight) Elongated upper trough will continue to move through the northern Rockies into the northern Plains today and tonight. These south to southwest winds will bring in a warmer airmass from the southwest across Oklahoma today. As the upper wave moves east into the Upper Midwest tonight a cold front will surge south in its wake, moving into northern Oklahoma overnight. This will mark the beginning of a much cooler week ahead.
With high pressure scooting across the region today, easterly winds will become more southeasterly.
Guidance has trended a bit further north with the boundary's ultimate position and also a bit weaker with the low-lvl convergence/moisture pooling, so rain chances today will be limited to the far northern portions of the area (i.
Wyoming currently sits under strong zonal upper atmosphere flow, with a slight southwesterly component aloft due to a low- amplitude trough over the West Coast.
- Cooler with rounds of precipitation mid to late week. Mid-level flow is becoming more southwesterly across the Plains this morning as troughing moves onto the western CONUS. East central Kansas remains on the southeast periphery of this low, keeping southwest winds elevated overnight and limiting radiational cooling. Cooler, but not overly cold, air moves in for Monday with highs in the mid 50s to mid 60s.
A compact area of low pressure is bringing widespread showers to the region at this hour. All advisories and warnings end at 4 pm this afternoon, which still seems reasonable as the low pressure system moves out of the area. The other concern is a quick hitting burst of westerly winds in Humboldt and Del Norte counties as a small sting jet develops on the back side of the low. The first indication of these westerly winds has started to arrive with west gusts to 35 mph on Bear River Ridge Road as of the last hour. A short 6 hour wind advisory has been issued for the coast of Humboldt and Del Norte counties and the ridges through 10 am.
A tighter pressure gradient evolves between the departed high and approaching low pressure from the Plains. So appears more lake influence with an easterly component more likely so cooler temps off the cold lake and the cloud cover.
508 AM CST Sun Mar 5 2023 Latest surface analysis was showing that the cold front has moved down to near I-70 at this hour with light winds across Missouri and Illinois. Highs today will climb into the lower-mid 60s as 850mb temperatures climb into the 5-10C range with a partly cloudy sky. A upper low over the Pacific Northwest will eventually move east this week, with the GFS digging a deeper trough over the Rockies by midweek compared to the more consistent ECMWF and Canadian which show a more progressive upper low moving across the Midwest late this week.
