- Cooler temperatures and mainly dry conditions to be found today.
An upper level trough over Western Washington will shift east of the region on Tuesday.
457 AM CST Mon Mar 4 2024 - Breezy and cooler for Monday. 07z observations show a large upper level longwave trough extending from the Pacific coast to the Great Lakes and a subtropical jet along the CONUS-Mexico border. With the tighter pressure gradient on the west side of the low we will see winds increase through the morning and early afternoon hours sustained at 15-25 mph with gusts approaching 35 mph. however with the cooler temperatures and higher humidity values the fire danger should be much less than this previous weekend. This will mean another day of cooler air hanging around much of western Kansas.

227 AM MST Mon Mar 4 2024 - Cooler temperatures are forecast for much of the upcoming week with near average temperatures today and tomorrow.
Weak tornadic storms are the lowest risk but as usual, we won't rule them out either.
648 AM EST Mon Mar 4 2024 -Unusually Warm Monday, Broken Records Possible -Showers and Storms Monday Night into Tuesday -A little cooler, then rain late in the week -Unusually Warm Monday, Broken Records Possible One more day of unusually warm conditions is expected Monday as robust warm air advection and moisture transport continues. -Showers and Storms Monday Night into Tuesday A cold front then approaches the points after 00z and then moves southeast through the night and into the day Tuesday. Given the lower instability values and weaker deep layer shear severe weather is not expected with these storms. -A little cooler, then rain late in the week Showers will be ending Tuesday evening in the far southeast cwa and then we'll see a couple of dry days high pressure over northern Ontario noses into the Great Lakes.
- Cool and unsettled weather will continue much of the period as a series of fast moving weather disturbances pass across the region, then warmer temperatures will occur for the weekend with ridging aloft. Cold front lays along a line from Alliance to Bill to Cody this morning. Given the high T/Td spreads out there.
A cold front in the Plains will slowly head toward Arkansas today/tonight, and will cross the state on Tuesday. Slightly cooler/drier air will follow the front, but the changes in air mass will be subtle.
The low pressure system that will be dropping out of British Columbia tonight into Tuesday has shift slightly farther south according to the latest model runs.

1233 PM MST Mon Mar 4 2024 1216 PM MST Mon Mar 4 2024 -Compact short wave may bring an inch or two of snow to the Northern Black Hills and parts of the western SD plains tonight -Unsettled pattern with on/off chances for light snow through mid week -Dry and mild late week/weekend Water vapor shows upper trof covering the western/central CONUS. Those specific areas are hard to determine, but they will most likely be somewhere from around/east of Pine Ridge and northeastward through Faith.
The current flow aloft is pretty flat with troughiness east of the state. In addition, sOme of the upper level energy associated with the aforementioned trough could aid the development of storms later today. Then, the upper level flow is disturbed by approaching low pressure system on Tuesday. Therefore, the highest chances remain mostly east and north of the CWA early.
230 PM CST Mon Mar 4 2024 - A slow-moving cold front is expected to pass through central and southeastern Illinois this evening through tomorrow morning.
With this, winds have comes down below High Wind criteria and we've elected to cancel the High Wind Warning. A cold front will enter the region from the northeast late Tuesday, but will do little to affect our weather.
This will be when temperatures reach their peak in the lower to mid 70s. The rain and cloud cover should keep temperatures a bit cooler with highs in the mid 60s northeast to lower 70s southwest.
Arends Current 500 mb analysis shows slight ridging building into the region which will make for a dry day for most across the region. Ensembles show PVA feeding into the low to our northeast, setting up over southern MT/northern WY for Monday afternoon/evening.
(This afternoon through Tuesday Night) Pretty quiet day so far across the mid state with temperatures into the low to mid 70s. Trough off to our SW will move eastward today and tonight, and increase rain chances overnight and especially into Tuesday.
Temperatures are above freezing this morning, so most of the snow will melt in the morning hours. An upper level trough over Western Washington will shift east of the region on Tuesday.
- Much cooler, though still above normal, for the rest of the work week. troffing. Deep southwesterly flow ahead of this troffing is transporting unseasonably rich moisture into the area (Precipitable Water values around 1", better than the 90th percentile for this time of year, expected by tonight). a wavy frontal occluded/cold front curves from northwest Ontario, through the western Great Lakes, into the southern Plains this afternoon. PATTERN SYNOPSIS/FORECAST: A broad trough is noticed stretching across northern CONUS with a strong jet draped over the Great Lakes region.
The combination of consistent cloud cover combined with limited sunshine will help keep afternoon highs in the low 70s through the afternoon.
Also lowered high temperatures across the northwest third or so of Oklahoma with models under estimating quality of cooler air. (Today and tonight) A weak cold front will gradually move through the northwest two- thirds of Oklahoma by late afternoon.
For pops, have gone with slight chance to chance pops for today with the higher pops over the western half of the area. Fog development is possible over much of the area again for tonight into early Tuesday morning, but am anticipating that mixing associated with the high coverage of precipitation will limit coverage. Lows tonight range from around 60 inland to the lower 60s closer to the coast.
1214 PM CST Mon Mar 4 2024 - Breezy and cooler for Monday. 07z observations show a large upper level longwave trough extending from the Pacific coast to the Great Lakes and a subtropical jet along the CONUS-Mexico border. With the tighter pressure gradient on the west side of the low we will see winds increase through the morning and early afternoon hours sustained at 15-25 mph with gusts approaching 35 mph. however with the cooler temperatures and higher humidity values the fire danger should be much less than this previous weekend. This will mean another day of cooler air hanging around much of western Kansas.
343 PM EST Mon Mar 4 2024 - Showers Tonight and Tuesday, a Few Storms Possible - Cooler with Chances for Rain and Snow to End the Week - Showers Tonight and Tuesday, a Few Storms Possible Slow moving frontal boundary works through tonight and Tuesday bringing an 80-100 percent chance of rain with the highest rainfall amounts of 0. Unusual nighttime warmth/humidity for this time of year will occur the bulk of the night, thanks to corridor of mid to upper 50 dew points preceding the slow moving cold front. North-northeast winds behind the cold front on Tuesday night send a cooler/drier air mass into the region with lows falling to 25-30 up north where clearing is more likely, to the mid 30s across srn sections where clouds should hang on a bit longer.
(Rest of today through Tuesday) An area of low pressure sits along the Carolina coast with a moist, warm airmass to the south over much of the peninsula of Florida. The pattern is similar for Tuesday though the focus for the moisture may shift north as a warm front develops and the next low approaches from the west over the northern Gulf.
The inverted trough located off the coast of the Carolinas will continue lifting northward today, with the weak boundary finally diminishing.
318 PM EST Mon Mar 4 2024 A cold front will slowly drift southeast across the Great Lakes and Ohio Valley Tuesday into Tuesday night, leading to chances for showers and a few thunderstorms.
This has allowed temperatures to generally reach highs in the lower 80s with only a few locations along the Middle Keys currently just shy of 80. This is likely due to the pockets of dry air in the lower to mid levels of our atmosphere hindering convective development. As this trough continues north and the effects of daytime heating on the pressure gradient wear off, high pressure in the western North Atlantic will take hold of our winds freshening them out of the east this evening. Tuesday, deep layer troughing in the Great Plains will spur on cyclogenesis along Texas/Louisiana. The resulting low pressure will trail along the northern Gulf coast towards north Florida stringing moisture along south of it.
Cooler temperatures are expected tonight behind the front with lows ranging from around freezing in NW OK to the mid 50s in SE parts of the area.
1006 AM MST Mon Mar 4 2024 - Cooler temperatures are forecast for much of the upcoming week with near average temperatures today and tomorrow.
215 PM EST Mon Mar 4 2024 After a very mild afternoon, our weather will turn unsettled tonight into Tuesday as a weak area of low pressure slides up the East Coast and brings rain to eastern Pennsylvania.
Our forecast highs in the lower 80s should still be achievable however, seeing that current temperatures along the island chain range from the upper 70s to near 80. This morning's balloon sounding observed several pockets of dry air in the lower to mid layers that add even more against shower formation. These slight chance PoPs will continue into tonight as easterly breezes slightly freshen as the high regains control of our winds. From synopsis, the western periphery of high pressure located over the western North Atlantic will continue to result in light to gentle east to southeast breezes for the rest of today through Tuesday night with occasional moderate breezes.
A cold front currently extends from northeast Kansas through western Oklahoma and into northwest Texas. Shower and thunderstorm activity will gradually increase tonight into Tuesday morning ahead of a cold front that will slowly move toward the area.
103 PM EST Mon Mar 4 2024 Calm conditions continue Monday into Tuesday morning as weak high pressure slides east, ahead of a low pressure system.

Not sure about further extent of dense fog westward given clouds are increasing tonight and an mid/upper level trough is approaching tonight. Included some isolated showers tonight well offshore near an inverted trough.
The initial precipitation type should be snow over western areas, but will likely begin as rain across the high plains as temperatures remain in the lower/ mid 40s. Otherwise, the main focus is the high wind potential this evening and overnight across the south- east Wyoming wind corridors as H7/H85 CAG-CPR gradients climb to near 50-60 meters in response to cyclogenesis over northeast Wyo late this afternoon. This will be the better opportunity for Bordeaux and the South Laramie Range/Foothills, but in-house random forest model guidance suggests the lower elevations could see gusts approaching warning criteria as well.
626 PM EST Mon Mar 4 2024 A cold front will slowly drift southeast across the Great Lakes and Ohio Valley Tuesday into Tuesday night, leading to chances for showers and a few thunderstorms.
