Low level southwesterly flow will see a modest uptick in strength with resultant wind gusts in the upper teens to lower 20s through this afternoon as gradients tighten in advance of a weak cold front slated to approach overnight. Although rather moisture starved, this cold front could yield some sprinkles across our northeastern counties for a few hours during the overnight hours. These will create slight chances for precipitation across the far north and east, along with gusty winds at times, particularly Wednesday night across the higher terrain. In addition, the wind and cloud cover associated with these disturbances will keep overnight lows slightly warmer than previous nights.
944 PM CST Mon Feb 28 2022 An area of high pressure located over north-central Texas has slowly meandered southeast through the day today and per latest sfc analysis, it has made it to the ArkLaTex region. Surface and mid level high pressure will be centered over our region for the next two days.
Temperatures will warm into the lower to mid 40s most areas with upper 30s holding on from northern Saginaw Valley into the Thumb.
High pressure out of the srn Plains continues to gradually build NE into much of the region this Mon evening translating into quiet and near seasonal wx conditions for the cntrl TN Valley. Current temps have fallen mainly into the upper 30s/lower 40s for many spots, and with a low level flow out of the NW, lows Tue morning look to fall predom into the lower 30s. We can expect beautiful weather to kick off the month of March on Tuesday and Wednesday as high pressure remains in control of our weather. We can expect an even warmer day on Wednesday, with readings in the lower 70s being common.
1100 PM CST Mon Feb 28 2022 Upper level ridging will continue to put our region in an area of northwest to west-northwest flow aloft will allow for well above average temperatures to continue through the short term period.
Overnight lows will reach the low to middle 30s. Slightly deeper boundary layer mixing between 825-800 mb should yield even warmer temperatures in the low to middle 70s. The low level environment will remain warm and dry with temperatures in the mid to upper 70s. Beyond Wednesday, midlevel ridging will overspread the region with a lee trough developing ahead of a deep trough across the southwest US.
Latest TAFB /WPC analysis has the cold frontal boundary offshore and continuing to move eastward with its parent low off the coast of central/northern FL. With the highest moisture pools well to the east, rain chances will be on the low end today, however non-zero. High pressure regains dominance by Wednesday, with a short-lived shower continuing to be possible across the east coast and adjacent waters due to onshore flow. Models insinuate that South FL may remain on the drier west side of the amplifying trough with little if any shower development expected.
1120 PM EST Mon Feb 28 2022 Mostly dry and increasingly warmer weather will be in store through mid week with highs in mid 40s to lower 50s.
1007 PM MST Mon Feb 28 2022 Upper ridging over CO will keep dry and warm conditions across the region. Clear skies tonight will allow for cooler temperatures given efficient radiational cooling for some of the interior valley locations, while lee troughing and light westerly winds keep temperatures warmer for the downsloping areas along and west of I- 25. Tomorrow will be dry and warmer across southern CO with temperatures starting top top out around 70 across the lower Arkansas river valley region. Winds look light under the ridge which should mitigate the potential critical fire weather conditions as gusts are not likely to get over 20 mph.
Mid-level northwest flow exists across the region early this morning ahead of the persistent western CONUS ridge. Forecast soundings show a shallow inversion in place with temperatures at 925mb (about 1500 feet AGL) in the low 60s, so temperatures will be quick to warm once the sun rises and mixing commences. Given slightly warmer low-level temperatures and deeper mixing, highs will be even milder than yesterday reaching the mid to upper 70s.
1234 AM EST Tue Mar 1 2022 High pressure will maintain dry conditions before rain and snow chances return with a mid week front. As well, assisted lift along the colder ridgetops in the southeast could also stand to see a few snow showers. The northern areas along and north of I-80 will still be cold enough for a few snow showers Wednesday night and also along the ridges where some very minor accumulations are possible.
1220 AM EST Tue Mar 1 2022 A warmer south to southwest flow can be expected across the region tonight into Tuesday. A weak cold front will then pass southeast through the area Tuesday night, followed by weak high pressure on Wednesday.
Expecting continued upper ridging across the Wern CONUS and NW upper flow across the Plains and south-central CONUS through the period. WSW low-level flow will return warmer air to the state over the next several days. High temperatures are topping out in the lower to mid 60s today, upper 60s to lower 70s Tues, and in the lower to mid 70s Wed afternoon.
Today through Wednesday An upper level ridge will be in place over the Northern/Canadian Rockies today and Wednesday, putting the Cowboy State on the eastern side of the ridge axis.
Low temperatures should remain above freezing, mostly in the upper 30s and low 40s. Temperatures will get progressively warmer each day, most notable in the overnight lows since passing mid/upper clouds Tuesday and Wednesday could regulate afternoon heating some.
Adjusted temperatures to match current observations and trends since a few areas were running slightly cooler than the forecast. A weak trof over the Great Lakes region moves a few clouds across overnight, otherwise dry conditions persist through Tuesday morning. Southwesterly flow just off the surface tonight moderate low temperatures closer to normals with readings in the low 30s, except in the 20s along mountains. These will create slight chances for precipitation across the far north and east, along with gusty winds at times, particularly Wednesday night across the higher terrain. In addition, the wind and cloud cover associated with these disturbances will keep overnight lows slightly warmer than previous nights.
1027 PM MST Mon Feb 28 2022 An upper-level ridge of high pressure will continue to strengthen over the region over the next 36 hours.
Temperatures will be trending warmer through the week.
255 AM CST Tue Mar 1 2022 Skies are clear across the Mid-South early this morning with temperatures ranging from the lower 30s to lower 40s. Currently, high pressure covers much of the eastern and southern U. High pressure will remain across much of the Mid-South for the next couple of days. Temperatures will be warmer today with highs in the mid to upper 60s. Wednesday will be a few degrees warmer than today with highs in the mid 60s to lower 70s.
Low pressure will transition east over the northern Great Lakes today with a trailing cold front progged to cross the region later this afternoon and through the evening, returning a chance of precipitation to the region.
Highs today will be in the lower 70s and overnight lows will be in the upper 30s to lower 40s.
VFR conditions will prevail for the next 24 hours with high pressure in control. /issued 322 AM CST Tue Mar 1 2022/ SHORT TERM (Now through Wednesday): Broad 500mb ridging over Central Mexico will maintain a dry and west to northwest flow aloft over Deep South Texas through Wednesday. At the surface, high pressure across Texas this morning is expected to gradually slide farther eastward through the midweek. Mostly clear skies and light winds prevail across the CWA early this morning with temperatures ranging from the mid to upper 30s across the Northern Ranchlands to the low to mid 40s across the Rio Grande Valley. Lows tonight will range from the mid 40s across the Northern Ranchlands to the low to mid 50s near the coast.
450 AM CST Tue Mar 1 2022 Surface pressure falls today as weak high pressure loses its influence across the area. We continued with the warmer high temps and lower dew points approach (though values should be up a bit).
SFC trof to also sweep thru the CWA veering the LLVL wind profiles to the northwest by afternoon, but ongoing mild air mass/high thicknesses in place along with mild start to the day will launch into another mild day for the start of the month/meteorological spring. A few of the CAMs/HiRes solutions want to produce some spotty light freezing rain at the sfc along Hwy 20 toward 12z, but the models may be too cold at the sfc. This system will drop a cold front in from the north during the afternoon and evening, setting up a large temperature gradient with highs in the mid/upper 60s south of I-80 to around 50 F along highway 20.
The High Wind Watches and the High Wind Warning across the Arlington wind prone area were allowed to expire this morning. Overnight GOES-W WV imagery depicted a upper level ridge centered over the Intermountain West, with west to northwest flow aloft. The High Wind Warning has already verified for WY Zones 106 and 110. Winds have been close to meeting criteria in the High Wind Watch (WY Zones 116 and 117).
626 AM EST Tue Mar 1 2022 Dry and warmer weather is on tap into Wednesday before a cold front brings a brief shot of colder weather and a small chance for some light rain or snow by Wednesday night. The clouds have helped temperatures remains fairly steady much of the night, but these same clouds (which continue well upstream into MN) could hamper full mixing of the warmer h85 temps that will be in place to start the day (but begin to lower across the north as the wave passes through. The warmer air will be nudged south briefly tonight with h85 temps back to 0 to +3 C, yielding lows in the 30s.
Weak mid level disturbances riding over weak ridging aloft will bring variable amounts of cloud cover thru the period but moisture availability much too low for rain.
SHORT TERM (Now through Wednesday): Broad 500mb ridging over Central Mexico will maintain a dry and west to northwest flow aloft over Deep South Texas through Wednesday. At the surface, high pressure across Texas this morning is expected to gradually slide farther eastward through the midweek. Mostly clear skies and light winds prevail across the CWA early this morning with temperatures ranging from the mid to upper 30s across the Northern Ranchlands to the low to mid 40s across the Rio Grande Valley. Lows tonight will range from the mid 40s across the Northern Ranchlands to the low to mid 50s near the coast.
603 AM EST Tue Mar 1 2022 Currently sitting in between dense clouds to the north associated with a low pressure system tracking through northern lower and a ribbon of high clouds to the south extending out from a weak mid level system that will skirt southern MI this afternoon along a cloud front that will get pulled through the area. Late tonight there is potential to transition from the low stratus back to a mid cloud deck. Temperatures will warm into the lower to mid 40s most areas with upper 30s holding on from northern Saginaw Valley into the Thumb.
345 AM CST Tue Mar 1 2022 An unseasonably warm start to March is expected across the local area today as temperatures climb into the lower 70s across much of the region. While temperatures aloft are very similar to yesterday, with the warmer start to the day and full sunshine, think that we should top yesterdays highs by a few degrees. As the upper level ridge aloft pushes further east on Wednesday, expect temperatures to climb even further, with widespread readings in the mid 70s expected across south central Nebraska, along with a few 80s possible across north central Kansas.
In the last 12 hours, the highest rainfall totals have been from our neighbors to the north in Florence picking up 0. 91 of an inch at Charlotte Ridge, 0.
425 AM EST Tue Mar 1 2022 High pressure along with drier air will build into the region through mid-week.
Today and tomorrow, upper low, currently over the Colorado Delta, will slowly advance eastward and transition to an open wave.
Water vapor imagery/GOES winds depict an upper trough over the Baja CA region.
At the surface, weak high pressure is situated down over the Lower Mississippi Valley with a broad area of west/southwest flow over the central/southern Plains. It's not out of the question that a few high temp records could be broken the next couple of days, especially if we get a couple degrees warmer than what we currently have going. Upper ridging is still forecast to move into the Plains on Thu as a sharp trough starts to come onshore over the West Coast.
An atmospheric river event continues to target Washington, Oregon, the Idaho Panhandle, and wrn Montana with copious rain/snow, while the best moisture feed is deflected to our north by a ridge over the nrn Rockies.
WV imagery and current RAP 500 mb analysis depict ridging over the wrn CONUS, with an axis extending from ern BC/wrn AB swd thru the Great Basin. Nonetheless, with temps for most having been more consistent with NBM 50th to 75th percentile over the last couple of days, feel pretty confident going with a blend of these rather than the deterministic NBM (which remains several degrees cooler). Downslope component to the low-level winds will further aid warming, particularly along the ern slopes/w cntrl SD plains, where temps could touch low 70s in spots. Cooler across nwrn SD, where some snow pack remains. Initial impact of a wind shift toward upslope flow over the wrn/cntrl SD plains will lead to slightly cooler temps tomorrow aftn, though 50s and 60s remain likely outside of far nwrn SD.
Moisture streaming in from the west will bring chances for mixed precipitation on Wednesday with mainly rain south and a mix of freezing rain and light snow north.
625 AM EST Tue Mar 1 2022 Aviation - Clippers bring chance of light precip today and Wednesday The large scale pattern the next couple days features fast northwest flow between western CONUS ridging and an upper low over eastern Canada. A departing clipper trails a cold front through Lower Michigan today with light snow/rain possible across the southern zones this afternoon, in an area of low level convergence.
Along and south of I-94, Tuesday starts with a chance for freezing drizzle and light snow, where as other areas can just expect light snow. Little to no accumulation of ice is expected from this, but freezing drizzle can complicate the morning commute, as it makes for hazardous travel. High pressure will build in at the surface to our north on Wednesday, and this gradient makes it a little bit more breezy, with winds of 10 - 20 MPH sustained, with gusts up to 25 at times.
This low will weaken Wednesday and lose its features as a high pressure ridge strengthens over the Western US. With the start of a new month temperatures will be warmer today as highs in the 70s return.
508 AM MST Tue Mar 1 2022 Building high pressure to the west of Colorado expected today with a light northwest flow aloft.
505 AM CST Tue Mar 1 2022 (Today and tonight) The very warm late winter trend continues today with general upper- level ridging to the west of Oklahoma.
An upper ridge that covers a large portion of the southern United States will produce benign weather conditions for the next few days, with plenty of sunshine and above normal daytime temperatures.
412 AM MST Tue Mar 1 2022 Aside from a few clouds across northwest Colorado, skies remain clear this morning thanks to the ridge of high pressure in place over the Four Corners region. A cutoff area of low pressure along the California/Arizona border has set up a Rex Block that will keep eastern Utah and western Colorado high and dry through the end of the work week.
Light rain is expected in the late week and into the weekend with much cooler high temperatures expected. Wednesday will be the start next cooling trend, but highs will only be a few degrees cooler. The end of the week shows a passing trough that will cause much cooler highs for the rest of the work week, and also bring rain. Yet another update on the late week chances for rain: Models and ensembles continue to slow the trough, pushing back the start times for the late week rain.
Few to scattered high clouds are forecast mainly over central and southern parts of the forecast area (east of the continental divide) as a weak low pressure system passes eastward over southern AZ.
Due to dry air aloft present in soundings in central Minnesota, freezing rain is possible mixed with snow in these areas.
Dry weather will continue through the period with warmer than normal highs this afternoon and cooler than normal lows tonight.
/issued 229 AM CST Tue Mar 1 2022/ An upper level ridge covering the western CONUS will continue to move east today with a weak closed low underneath it traveling across southern Arizona today. Strong subtropical jet winds aloft today will decrease as this ridge moves east and the closed low further weakens.
/issued 255 AM CST Tue Mar 1 2022/ Skies are clear across the Mid-South early this morning with temperatures ranging from the lower 30s to lower 40s. Currently, high pressure covers much of the eastern and southern U. High pressure will remain across much of the Mid-South for the next couple of days. Temperatures will be warmer today with highs in the mid to upper 60s. Wednesday will be a few degrees warmer than today with highs in the mid 60s to lower 70s.
226 AM MST Tue Mar 1 2022 Aside from a few clouds across northwest Colorado, skies remain clear this morning thanks to the ridge of high pressure in place over the Four Corners region. A cutoff area of low pressure along the California/Arizona border has set up a Rex Block that will keep eastern Utah and western Colorado high and dry through the end of the work week.
508 AM CST Tue Mar 1 2022 (Today) March will begin on a warm note with high temperatures forecast to be 15 to 20 degrees above normal as high pressure prevails at the surface.
- There are several chances for precipitation over the weekend in which thunder, rain, snow, sleet, and freezing rain could be observed.
524 AM CST Tue Mar 1 2022 An unseasonably warm start to March is expected across the local area today as temperatures climb into the lower 70s across much of the region. While temperatures aloft are very similar to yesterday, with the warmer start to the day and full sunshine, think that we should top yesterdays highs by a few degrees. As the upper level ridge aloft pushes further east on Wednesday, expect temperatures to climb even further, with widespread readings in the mid 70s expected across south central Nebraska, along with a few 80s possible across north central Kansas.
A weak but persistent ridge remains over the forecast area today and Wednesday. Temperatures will increase another 5 to 8 degrees today reaching the low 60s in the Treasure Valley aided by light southeasterly winds.
A chilly start this morning with temperatures in the low to mid 30s. High pressure overhead provides ample sunshine and dry conditions allowing for temperatures this afternoon to rise into the mid to upper 60s.
421 AM MST Tue Mar 1 2022 Overnight GOES-W WV imagery depicted a upper level ridge centered over the Intermountain West, with west to northwest flow aloft. The High Wind Warning has already verified for WY Zones 106 and 110. Winds have been close to meeting criteria in the High Wind Watch (WY Zones 116 and 117).
105 PM EST Tue Mar 1 2022 High pressure along with drier air will build into the region through mid-week.
An associated cold front will push south across the region this evening into the overnight, but is expected to remain dry across much of the region. Temperatures will be similar to that of today, perhaps a few degrees cooler, with mid 50s to low 60s for the lowlands, and mid 40s into the 50s for the higher terrain. Precipitation will be light, and mainly in the form of rain, although a few flakes cannot be ruled out across the higher terrain.
(This afternoon through Wednesday night) A weak upper-level trough in southern Arizona continues to gradually slide eastward and weaken underneath a large upper- level ridge across the western US. Upper and mid-level clouds thin tonight and tomorrow as the upper trough moves east and weakens. 850 mb temperatures 2-3 Celsius warmer and less prevalent upper level clouds tomorrow supports more warming with highs in the mid-70s and 80s near the Rio Grande.
A weakening cold front will approach the area later tonight, however it will likely stall along or north of the I-64 corridor.
SHORT TERM (Tonight through Wednesday Night): High pressure continues to build across Deep South Texas, with very comfortable conditions expected both today and Wednesday. Highs should reach the low to mid 70s today and mid to potentially upper 70s tomorrow.
Upper level ridging will allow for northwest flow aloft and along with downsloping winds we should see temperatures near 80 on Wednesday.
Building high pressure to the west of Colorado expected today with a light northwest flow aloft.
VFR will continue through the next 24 hours under dry high pressure.
155 PM MST Tue Mar 1 2022 Sprawling upper ridge will be the dominant upper feature through the short term period.
156 PM MST Tue Mar 1 2022 Weak high pressure over the Intermountain West will slowly move eastward the next two days, bringing a flattened ridge axis over western and central Wyoming. Some moisture in the flow continues light snow showers to the northwest mountains today and tonight, with the showers diminishing after midnight as the ridge axis pushes moisture into SW Montana. With the ridge axis moving over the area on Wednesday, similar temperatures are expected with highs into the upper 50s and 60s.
Similar, though slightly warmer, weather is expected tomorrow, with high temperatures in the low to mid 70s.
1138 AM CST Tue Mar 1 2022 (Today and tonight) The very warm late winter trend continues today with general upper- level ridging to the west of Oklahoma.
Afternoon highs are expected to be in the mid to upper 60s across north Georgia and in the low 70s in central Georgia. Temperatures will be gradually warming underneath the high, with afternoon highs climbing into the low 70s in north Georgia and mid to upper 70s in central Georgia. Mixing down of dry air aloft is anticipated once again during the daytime hours, and hi-res solutions have been blended into the dewpoint forecast as a result to once again trend on the low side of the guidance.
245 PM CST Tue Mar 1 2022 (Issued 245 PM CST Tue Mar 1 2022) Tonight through Wednesday night: High pressure builds in for a quiet night across the area. Will be watching a cold front for Wednesday with some mid/upper level jet action riding in from the northwest. Some loss of cloud ice may result in a bit of freezing drizzle or very light freezing rain especially in the northern cwa. In the wake of the cold front passage in the afternoon northwest winds will bring some cold advection into the area with north to northeast winds right into Wednesday night.
224 PM EST Tue Mar 1 2022 High pressure becomes centered off the southeast coast through Wednesday.
Currently, temperatures in Key West and Marathon are near the lower 70s, and are only forecast to climb to 75 this afternoon. High pressure will slowly build over the southeastern U.
220 PM CST Tue Mar 1 2022 After a quiet start to the evening, will be watching next short wave trough dropping into the region in persistent northwest flow. Temperatures will be big factor and seems like trends have been for a slightly warmer profile overall. This could translate to lower of a freezing precipitation threat but still seeing loss of ice toward in model soundings so threat for at least patchy mix possible.
High pressure to our south and weak pressure gradient across the region will lead to light SWLY winds during the daytime hours, with light to calm winds overnight.
