553 AM CDT Mon Mar 18 2024 (Today through Tuesday night) Winds will remain light and variable for much of the day and then they will tend to become more southerly by sunset as high pressure moves off to our east. No precipitation is expected through Tuesday night as the upper low and is associated moisture stays west of the Panhandles.
903 AM EDT Mon Mar 18 2024 An upper level low pressure system will bring scattered to numerous snow showers and an unseasonable cold airmass to the Ohio Valley today.
- Temperatures warm back into the 60s by Tuesday before trending cooler again.
Unseasonably warm and dry weather will carry on through Tuesday with high pressure firmly entrenched over the region.
Widespread rain and high-elevation snow along with cooler weather returns by the end of the week. Winds are generally light except for local easterly wind gusts of 20-30 mph over ridges in the northern Sierra. Dry and unseasonably mild weather will continue early this week as the strong blocking ridge over the PacNW and NorCal gradually weakens. In addition to bringing warm weather, the high will likely suppress deep convection over NorCal. The ridge is forecast to weaken beginning mid-week allowing a return of temperatures closer to average the second half of the week.
627 AM CDT Mon Mar 18 2024 - Ongoing widespread sub-freezing conditions resulting in a hard freeze through mid-morning today. The long-advertised hard freezing is ongoing this morning with temperatures already in the middle 20s outside of the KC urban area. Highs today will remain around 10 degrees below normal in the lower to middle 40s. High pressure slides off to the south on Tuesday, with weak upper ridging, and westerly H85 winds developing nosing a thermal axis into the CWA, spelling a quick warmup after a cool start. Highs Tuesday afternoon will be some 25 degrees warmer than today, reaching the middle 60s to middle 70s.
244 AM PDT Mon Mar 18 2024 More chances for showers and isolated thunderstorms are expected today as an area of low pressure briefly moves closer to the region. High pressure makes a brief appearance by the middle of the week, before a Pacific trough brings cooler, breezier and potentially more wetter weather by the weekend.
615 AM CDT Mon Mar 18 2024 (Today through Tuesday) A deep trough will continue to dig into the southeastern US and bring some chilly early spring air to those folks. NNE to NE winds of 10-20 mph will gust to 25-30 mph at times, and highs will only reach the low to mid 60s in most areas. As the high settles in tonight, our northeastern areas should see some clearing skies and decoupled winds, which may allow a few locations to dip into the upper 30s by Tuesday morning.
A very cold and dry airmass will settle into the Lower Mississippi Valley through Tuesday. Widespread frost and sub-freezing temperatures are expected across the entire Mid-South late tonight.
623 AM CDT Mon Mar 18 2024 (Today and tonight) Weak ridging aloft through tonight as the upper low continues to spin over the Desert Southwest and a positively tilted longwave trough swings into the Mid-Atlantic. Sunny skies will finally make an appearance, but the cool air mass from the frontal passage yesterday will remain in place with below normal temperatures in the lower 60s. Southerly surface winds will return overnight tonight as the ridge builds into eastern Texas. Near normal temperatures are expected tonight in the 30s with chilly near freezing temperatures across the far southwest Texas Panhandle.
Humid conditions are sitting across the island chain this morning with temperatures currently in the low 80s and dew points in the mid to upper 70s, and winds of 5 to 10 mph continue out of the southeast to south. Gentle southeast to south breezes will turn around the clock today as a cold front approaches, with freshening breezes late tonight into Tuesday morning.
(Rest of today through Tuesday) It's dry and cool today with a bit of a breeze thanks to a passing upper trough axis. The passing trough will send a reinforcing shot of cold air overnight tonight, which will send temperatures into the low to mid 20s by Tuesday morning. After this cold dip, we'll stay above freezing for the foreseeable future, which is at least a week in our case.
For now, the upper low should remain over Arizona, which could keep feeding mid-level moisture for cloud cover across our southern counties. Given the south winds, temperatures should be a little warmer in the afternoon than today.
- Sub freezing temperatures are forecast again tonight into Tuesday morning.
- A wetter and cooler weather pattern looks to develop this weekend continuing through the remainder of March. This is in large part thanks to a persistent ridge of high pressure, that has set itself up over the western CONUS. This area of high pressure has created a blocking pattern which will keep things rather uneventful. While slightly cooler than areas east of the Divide, western WY will still see mild temperatures, with highs in the upper 40s to low 50s. The second half of the week will see this blocking pattern gradually fall apart, in turn allowing westerly flow to return.
1237 PM CDT Mon Mar 18 2024 (Today through Tuesday night) Winds will remain light and variable for much of the day and then they will tend to become more southerly by sunset as high pressure moves off to our east. No precipitation is expected through Tuesday night as the upper low and is associated moisture stays west of the Panhandles.
While weather remains quiet in the backyard, thunderstorms along the leading edge of a cold front are approaching the forecast area. Any residual showers taper off tomorrow morning by sunrise, leaving behind cooler and less humid conditions as we head into the midweek.
245 PM CDT Mon Mar 18 2024 - Warmer Tuesday with Highs in the 60s and lower 70s.
Could see low temperatures ranging from the upper 20s across McCurtain county to around the freezing mark of 32 degrees as far south as I-20. High temperatures on Tuesday will average in the mid 60s with overnight lows on Tuesday night in the low to mid 40s.
The front itself will be rapidly decaying as it becomes further detached from its parent trough/low complex well to the NE. Highs could push into the low 90s in some areas.
111 PM CDT Mon Mar 18 2024 (Rest of today through Tuesday) It's dry and cool today with a bit of a breeze thanks to a passing upper trough axis. The passing trough will send a reinforcing shot of cold air overnight tonight, which will send temperatures into the low to mid 20s by Tuesday morning. After this cold dip, we'll stay above freezing for the foreseeable future, which is at least a week in our case.
Temps still on track to be below freezing across the CWA with min temps now as low as 25 in the northern counties and likely even cooler readings in northern and/or higher elevation valleys. Tuesday night temps also expected to approach freezing again but confidence in any kind of Freeze Watch is low at this time.
* Unseasonably cool through Tuesday morning, with subfreezing temperatures likely again tonight.
(Tonight) Another round of below freezing temperatures is in offing for tonight across much of eastern Oklahoma and western Arkansas with temperatures bottoming out in the mid 20s to lower 30s. (Tuesday through Monday) Considerably warmer temperatures are expected on Tuesday as west-southwesterly winds prevail.
1019 AM CDT Mon Mar 18 2024 Cool but dry conditions are expected today and tomorrow as high pressure shifts over the Midsouth. Warmer conditions return by midweek with highs near 70 degrees.
1240 PM EDT Mon Mar 18 2024 * Unseasonably cool through Tuesday morning, with subfreezing temperatures likely again tonight.
146 PM EDT Mon Mar 18 2024 An upper level low pressure system will bring scattered to numerous snow showers and an unseasonable cold airmass to the Ohio Valley today.
1037 AM MDT Mon Mar 18 2024 - Warmer weather, with occasional light mountain snow showers this upcoming week.
Mild and dry conditions will continue through today ahead of much cooler temperatures later into the week, especially for North- central and Central Montana. The amplified upper-level ridging for the last several days will continue to prevail through the next couple days, preserving the above seasonally average temperatures and dry conditions.
Cooler conditions can be expected on Tuesday, as winds shift to the north and east through the day.
An upper level low over Arizona will bring unsettled weather, especially into this evening to locales northeast of Tucson where scattered showers and even a few thunderstorms are expected.
1242 PM CDT Mon Mar 18 2024 (Today through Tuesday Night) High pressure will continue to build down from the Central Plains today but clouds probably won't be clearing much until this after- noon. Much drier and cooler conditions are on tap for tonight with lows mostly in the 40s across the FA (except for the Piney Woods where readings could drop into the upper 30s). Lows tomorrow night will be slightly warmer; in the low to mid 50s for most locations.
258 PM MDT Mon Mar 18 2024 - Warmer weather, with occasional light mountain snow showers this upcoming week. Surface observations show temperatures in the mid to upper 50s across the lower elevations. Some of the deeper snowpack areas are running a bit cooler a the lower 50s. Tonight, expect mainly clear skies with lows in the upper 20s and 30s for the lower elevations and teens/20s for the high country. Tomorrow will trend a bit warmer with some warming in temperatures aloft and decreasing snowpack. The upper level low (that once helped bring last weeks snow) will slowly shift eastward across AZ.
- Temperatures warm back into the 60s tomorrow before trending cooler again.
Elsewhere, nighttime temperatures will fall into the lower 30s. This will lead to widespread frost development across our entire CWA along with several hours of temperatures below freezing. The combination of frost and freezing temperatures will likely kill unprotected sensitive vegetation. Areas south of I-20 will see daytime highs in the low 60s.
(This afternoon through Tuesday night) Light showers have developed and are stretching across the the Lower Trans Pecos.
Upper level troughing extending southwest from the Great Lakes will move eastward over the next 24 hours. On the surface, an area of low pressure and cold front will move across Florida today with scattered showers and storms spreading from north to south through the day. The cold front pushes south and east of the area by late Monday evening allowing for strong high pressure to build in from the northwest.
Upper ridging continues across the Pacific Northwest today for dry weather and well above normal temperatures.
There is even sunny skies over the Hill Country as of this writing with temperatures in the low to mid 60s and upper 50s to low 60s where clouds are dominating.
1235 PM CDT Mon Mar 18 2024 - Ongoing widespread sub-freezing conditions resulting in a hard freeze through mid-morning today. The long-advertised hard freezing is ongoing this morning with temperatures already in the middle 20s outside of the KC urban area.

High pressure slides off to the south on Tuesday, with weak upper ridging, and westerly H85 winds developing nosing a thermal axis into the CWA, spelling a quick warmup after a cool start. Highs Tuesday afternoon will be some 25 degrees warmer than today, reaching the middle 60s to middle 70s.
With southwesterly surface flow returning tomorrow, high temperatures will range from the upper 60s to mid 70s, a few degrees warmer than today.
/96 (Now through Tuesday) A much cooler and drier airmass will continue to move into the area today in the wake of a cold front. Skies will clear by late this morning with high temps in the low to mid 60s inland to upper 60s along the coast.
Unseasonably warm and dry conditions will persist through the day tomorrow (Tuesday), as a ridge of high pressure keeps a firm grip over the Northern Rockies.
After a mild start this week, a turn toward colder and more wintry conditions will develop around mid-week for areas near the Canadian border then expand south across much of north-central and The mild and dry airmass that has been in place across the region will remain across central and southwest Montana through mid-week while a cooler airmass begins to move south into north-central Montana on Tuesday.
Our break from Spring (Spring Break) will last another 24 hours or so but sub freezing temperatures are likely tonight across all of the Midsouth.
These will begin to dissipate heading into this evening as we lose the diurnal component and the low level flow begins to back around more to the west. It will be a cold night with overnight lows in the low to mid 20s. This will help push a cold front southeast into our area through Tuesday night. This will lead to some decent drying through the day with RHs dropping down into the low to mid 20s through the afternoon. Highs on Tuesday will be in the low to mid 50s with lows Tuesday night in the low to mid 30s.
1209 PM CDT Mon Mar 18 2024 (Today and tonight) Weak ridging aloft through tonight as the upper low continues to spin over the Desert Southwest and a positively tilted longwave trough swings into the Mid-Atlantic. Sunny skies will finally make an appearance, but the cool air mass from the frontal passage yesterday will remain in place with below normal temperatures in the lower 60s. Southerly surface winds will return overnight tonight as the ridge builds into eastern Texas. Near normal temperatures are expected tonight in the 30s with chilly near freezing temperatures across the far southwest Texas Panhandle.
1250 PM CDT Mon Mar 18 2024 (Today through Tuesday) A deep trough will continue to dig into the southeastern US and bring some chilly early spring air to those folks. NNE to NE winds of 10-20 mph will gust to 25-30 mph at times, and highs will only reach the low to mid 60s in most areas. As the high settles in tonight, our northeastern areas should see some clearing skies and decoupled winds, which may allow a few locations to dip into the upper 30s by Tuesday morning.

SURFACE OBSERVATIONS RANGE FROM THE LOWER 50S TO MIDDLE 60S EAST OF THE LARAMIE RANGE. THIS IS ON THE ORDER OF 10 TO EVEN 20 DEGREES WARMER IN SOME LOCATIONS COMPARED TO THIS TIME YESTERDAY. FURTHER WEST OF THE LARAMIE RANGE, DAYTIME HIGHS IN THE 30S AND 40S ARE PRESENT, WHICH IS APPROXIMATELY 5-10 DEGREES WARMER THAN 24 HOURS PREVIOUSLY. SURFACE FRONTAL ANALYSIS DEPICTS A WEAK WARM FRONTAL BOUNDARY DRAPED ALONG A NORTH TO SOUTH TRANSECT FROM THE NORTHERN PLAINS DOWN TO THE TEXAS PANHANDLE. TAKING A LOOK AT GOES-16 SATELLITE WATER VAPOR IMAGERY, AN AMPLIFIED UPPER LEVEL RIDGE RESIDES ALONG PACIFIC COASTLINE, AND ELONGATING OVER THE GREAT BASIN AND INTERMOUNTAIN WEST, WITH THE CUT-OFF UPPER LEVEL LOW CENTERED NEAR THE BAJA CALIFORNIA REGION. THE AFOREMENTIONED UPPER LEVEL RIDGE IS WHAT'S RESPONSIBLE FOR THE ABOVE AVERAGE TEMPERATURES ACROSS OUR CWA.
626 PM CDT Mon Mar 18 2024 - Warmer Tuesday with Highs in the 60s and lower 70s.
Showers and isolated thunderstorms continue to drift south along and ahead of a cold front. With storms clearing over the next few hours and the continental airmass settling in, everyone will certainly be waking up to a cooler and drier morning, made more noticeable by the fact that it has been rather warm and humid. As a cold front moves through overnight, any lingering CIGs will quickly lift as VFR returns.
318 PM MDT Mon Mar 18 2024 - Periodic showery development, mainly across the higher terrain, and general warming trend expected this work week. - Returning precipitation chances and cooler weather expected late this weekend. A very quiet day over the region as very few clouds were noted on sat pix imgy (the snow, however, over the higher terrain, looks quite pretty in the cloud phase distinction imgy). Temps will be warming tomorrow, with readings running about 5 to 10F warmer than todays max temps. By Tuesday night, the upper low to the southwest will begin its slow track east across the region.
Unsettled weather and cooler temperatures return late in the week. Dry and unseasonably mild weather will continue during the first half of the work week as the strong high pressure persists over the NWRN CONUS.
Surface observations place a cold front over the eastern Gulf of Mexico and Central Florida. Northerly breezes will freshen sharply tonight as a cold front pushes through the coastal waters of the Florida Keys.
Looking for cooler conditions tonight as compared to last night. Temps still on track to be below freezing across the CWA with min temps now as low as 25 in the northern counties and likely even cooler readings in northern and/or higher elevation valleys. Tuesday night temps also expected to approach freezing again but confidence in any kind of Freeze Watch is low at this time.
Mid level trof has pivoted southeast thru the region this afternoon leaving a northwesterly flow. It will be a cold night with overnight lows in the low to mid 20s. This will help push a cold front southeast into our area through Tuesday night. This will lead to some decent drying through the day with RHs dropping down into the low to mid 20s through the afternoon. Highs on Tuesday will be in the low to mid 50s with lows Tuesday night in the low to mid 30s.
Typically gusty winds limit radiational cooling through mechanical mixing and this coupled with some higher clouds streaming overhead in response to a subtropical jet over the Gulf might help keep temperatures more in the mid 30s further south and only areas along and north of highway 84 to reach below freezing. On top of warmer temperatures, frost may be a little more difficult given rather large dewpoint depressions nearing 10 degrees or more and once again breezy conditions.
847 PM CDT Mon Mar 18 2024 High pressure is sitting off to our west and will build in for the overnight. High pressure will slowly drop south tomorrow as a low pressure system passes over the Great Lakes. (Rest of today through Tuesday) It's dry and cool today with a bit of a breeze thanks to a passing upper trough axis. The passing trough will send a reinforcing shot of cold air overnight tonight, which will send temperatures into the low to mid 20s by Tuesday morning. After this cold dip, we'll stay above freezing for the foreseeable future, which is at least a week in our case.

Tomorrow will trend a bit warmer with some warming in temperatures aloft and decreasing snowpack. The upper level low (that once helped bring last weeks snow) will slowly shift eastward across AZ.
pdf High pressure will build from the northwest through the night, with a trend toward clear skies. Temperatures will fall off sharply Tonight, with lows ranging from the mid 30s over inland SE GA, to the lower 40s over coastal NE FL. However, wind chills values will drop below freezing across most inland areas.
Upper ridging will continue into Tuesday for dry, warmer weather.
As an area of high pressure shifts eastward over the area overnight, these winds are expected to weaken and become very light. Lows in the mid to upper 20s will be common by early Tuesday morning and a Freeze Warning is in effect from 06z to 14z to account for temperatures dropping well below the freezing mark.
632 PM CDT Mon Mar 18 2024 (Tonight) Another round of below freezing temperatures is in offing for tonight across much of eastern Oklahoma and western Arkansas with temperatures bottoming out in the mid 20s to lower 30s. (Tuesday through Monday) Considerably warmer temperatures are expected on Tuesday as west-southwesterly winds prevail.
638 PM CDT Mon Mar 18 2024 Our break from Spring (Spring Break) will last another 24 hours or so but sub freezing temperatures are likely tonight across all of the Midsouth.
Widespread rain and high-elevation snow along with cooler weather returns by the end of the week. Mostly clear skies this afternoon, with a ridge of high pressure dominating the pattern aloft.
548 PM CDT Mon Mar 18 2024 (This afternoon through Tuesday night) Light showers have developed and are stretching across the the Lower Trans Pecos.
Bottom line, another night of sub-freezing temps is expected at some point tonight, but the time below freezing may be shorter than usual as mentioned in the discussion earlier. Lacy (Tonight) Another round of below freezing temperatures is in offing for tonight across much of eastern Oklahoma and western Arkansas with temperatures bottoming out in the mid 20s to lower 30s. (Tuesday through Monday) Considerably warmer temperatures are expected on Tuesday as west-southwesterly winds prevail.
Evening RAP/water vapor analysis indicate deep longwave trough centered along & east of the MS River basin while cutoff upper low remains stalled over the Desert Southwest/Baja California region. Temperatures are dropping quickly across the region, currently in the low-to mid 40s. Expect lows to fall well below freezing into the upper 20s, especially in cold drainage areas east of I-55 & especially into the Hwy 25 corridor. Along the MS River corridor, lows could fall near freezing. Elsewhere, nighttime temperatures will fall into the lower 30s. This will lead to widespread frost development across our entire CWA along with several hours of temperatures below freezing. The combination of frost and freezing temperatures will likely kill unprotected sensitive vegetation. Areas south of I-20 will see daytime highs in the low 60s.
The high pressure system will continue to bring stable conditions across the region, with above normal temperatures anticipated through Tuesday.
617 PM CDT Mon Mar 18 2024 (Rest of today through Tuesday) It's dry and cool today with a bit of a breeze thanks to a passing upper trough axis. The passing trough will send a reinforcing shot of cold air overnight tonight, which will send temperatures into the low to mid 20s by Tuesday morning.
