1242 PM EDT Tue Apr 16 2024 A warm front will push northward across the area today. Warm front remains draped overhead today and will begin sprouting isolated showers and storms later on this afternoon. This front will return northward later today as a warm front. Meso NAM shows effective layer CAPE of over 2000 at CRW and HTS this afternoon with a freezing level around 11000 feet. Models showing a line of showers and thunderstorms in Ohio moving eastward by daybreak Wednesday, ahead of an approaching cold front. Wednesday night the cold front with the aforementioned low approaches. Cooling aloft combined with low level moisture pooling along the frontal surface should yield some modest instability, 1000- 1500J/kg MLCAPE, modest deep layer shear of 30-35KTs, and some modest turning in the low level wind field.
259 PM CDT Tue Apr 16 2024 - Mild an windy this afternoon and Wednesday - Much cooler with a good chance for rain to end the week and into the weekend Current satellite shows a strong but seasonal storm system exiting the CWA to the east. Wednesday will be another mild day due to some slight ridging in the mid levels and light southerly winds providing weak WAA over the region.
pdf Dry weather and mostly clear to partly cloudy skies will continue through today and tonight as high pressure ridging extends over the region. Overnight low temperatures will drop down into the upper 50s and lower 60s for most inland areas and in the lower to mid 60s along the shoreline.
1228 PM CDT Tue Apr 16 2024 (Rest of Today) A broad warm sectored airmass will exist today across much of the Southeast, as upper ridging is slowly pushed east by a closed upper low tracking through the northern Plains. Will see a temporary decrease in cloud cover this afternoon, and southerly flow will keep highs in the low to mid 80s once again today. Southerly winds will also increase through the day as a tightening pressure gradient develops in response to the previously mentioned upper low.
This nearly stacked low will continue tracking northeast across the Great Lakes region through Wednesday and drag a weakening cold front into the northwest portions of our CWA this evening. This cold front will become more east-west oriented as it sags and then stalls near our Highway 82 corridor Wednesday. Our airmass will continue to moisten ahead of this approaching weak cold front this afternoon and evening. There will be low chances of rain over our northwest most zones later this afternoon and evening until the cold front actually moves into our CWA this evening. Temperatures will continue warmer than normal tonight and Wednesday.
355 PM EDT Tue Apr 16 2024 High pressure will lead to unseasonably warm and quiet weather through midweek. A weak back door front resides to the north of the area as Bermuda High Pressure continues to control the weather across the area. Otherwise a very warm forecast remains in place with overnight lows in the lower 60s and Wednesday's highs perhaps just a shade lower than today with middle 80s. Lows in the lower 60s.
Upper ridging us building behind the cyclonic flow, but the next storm is just behind. A cold front will cross the area early Wednesday morning, bringing in cooler temperatures, especially across northeast WY. Warmer temps across the western SD plains will keep precip as rain.
Afternoon high temperatures are expected to climb into the mid to upper 70s for the Valley, with cooler mid 50s to mid 60s for the higher elevations. Upper level ridging will continue to be the dominant synoptic pattern through the remainder of the week. As the upper level ridging continues to build and control the overall weather pattern, afternoon high temperatures will continue to climb as we move through the work week.
The highest precipitation chances and best accumulation potential will be along and east of Highway 83.
Gusty northerly winds are forecast for coastal areas through the middle of the week as high pressure builds into the region. A high pressure ridge continues to build into Northwest California. Warm air advection ahead of the building ridge will allow daytime temperatures to steadily climb into the 70s in interior valleys for the next several days. Long range models are indicating a minor breakdown in the high pressure ridge late this week and into the weekend, causing northerly winds to subside and shift further offshore. This will give an opportunity for the marine layer to deepen beneath broad high pressure subsidence, potentially dampening daytime warming along the coast if it moves onshore.
A weak cold front will bring light northern mountain snow Wednesday.
Warm, dry, and quiet this week as high pressure dominates. Onshore flow and increased cloudiness late week as weak trough moves in.
645 PM CDT Tue Apr 16 2024 (Tonight through Wednesday night) A quasi-stationary upper pattern is expected during the period, yet with an upper low across the northern CONUS/southern Canada Wednesday (deterministic NAM/ECMWF/GFS).
321 PM MDT Tue Apr 16 2024 A Canadian cold front will bring periods of snow and gusty northerly winds tonight into Wednesday, with the heaviest snow over mountain areas and their adjacent northerly facing foothills.
745 PM EDT Tue Apr 16 2024 High pressure will push eastward tonight as low pressure tracks into the Great Lakes.
728 PM EDT Tue Apr 16 2024 High pressure and upper ridging will build over the southeastern states during the first part of the week resulting in warm and dry conditions. A cold front will bring a chance of showers and thunderstorms late week. The front may stall near the area late in the weekend with cooler temperatures and scattered showers. Therefore, lows should end up in the low 60s. Wednesday and Wednesday night: Mid to upper ridging begins to flatten through the day Wednesday as a trough slides by to our northwest, which is forecast to lead to plenty of cloud cover for the day. A mature surface cyclone is expected to move from the Upper Midwest into the Great Lakes.
(Tonight through Wednesday night) A quasi-stationary upper pattern is expected during the period, yet with an upper low across the northern CONUS/southern Canada Wednesday (deterministic NAM/ECMWF/GFS).

606 PM CDT Tue Apr 16 2024 (This afternoon through Wednesday night) Early this afternoon, skies were clear behind a cold front with temperatures in the upper 70s to low 80s. Weak high pressure was filling in across eastern New Mexico and west Texas.
High pressure continues to bring dry conditions to the region tonight. Low temperatures tonight will generally range from the lower 60s across the Lake Okeechobee region to the lower 70s across the east coast. (Rest of today through Wednesday) Tranquil conditions continue over the area today, as mid-lvl ridging oriented over the central GOM builds towards the area and high pressure over the western Atlantic continues to support moderate easterly low-lvl flow. The aforementioned synoptic pattern remains in place on Wednesday with ridging remaining in control and continued dry conditions. Slightly higher mid-lvl heights and slightly weaker easterly flow will result in temperatures ticking up a degree or two relative to today, generally ranging from the low to mid 80s on the east coast, to the mid to upper 80s over Interior and SW Florida.
932 PM EDT Tue Apr 16 2024 High pressure over southern New England will bring dry weather through mid week. It will be cooler Wednesday along the coast with sea breezes.
Deep layered ridging remains in control with a formidable subsidence inversion still based around 900 mb and substantial dry air above. Short Term Update - Surface winds will remain moderate out of the east northeast along the island chain through the overnight period due to the ridge to our north. Deep layered ridging and dry air from the lower levels up will remain in place. As a result, somewhat warmer and decidedly more humid conditions will prevail, rain chances will remain slim to none.
A low pressure system tracking through the Great Lakes will push a cold front through the region this weekend. Scattered showers and thunderstorm activity from this afternoon has diminished across the area as the warm front has lifted northward, and the cold front has dropped to the south, leaving the area in between the two fronts, per the latest surface analysis. Latest guidance suggests the cold front retreats north as a warm front throughout the day Wednesday.
- Mild an windy this afternoon and Wednesday - Much cooler with a good chance for rain to end the week and into the weekend Current satellite shows a strong but seasonal storm system exiting the CWA to the east. Wednesday will be another mild day due to some slight ridging in the mid levels and light southerly winds providing weak WAA over the region.
A cold front moving through SE Oregon this evening will cross SW Idaho overnight, accompanied by gusty winds to around 30 mph. Cooler temperatures follow the front with highs on Wednesday around 5 to 10 degrees below normal. An upper trough will bring limited moisture (generally dry but with clouds) through Wednesday, but there is a 15 to 30 percent chance of snow showers in the West Central ID mountains.
A weak wave embedded in the flow on the backside of the low will skirt northwest Colorado through the remainder of the day, allowing light, periodic snow to linger before largely ending after sunset. However, lower heights will continue to dominate the short term period as yet another upper level trough digs into the Northern Rockies. The cold front won't be much to speak of but it will bring a slick decrease in temperatures north of I-70.
748 PM EDT Tue Apr 16 2024 High pressure will push eastward tonight as low pressure tracks into the Great Lakes.
(Wednesday through Tuesday) Wednesday will be a very warm day across eastern OK and western AR as Tuesdayâs frontal boundary lifts back north as a warm front during the daytime.
Winds remain somewhat elevated across the Missouri bootheel so will leave the Wind Advisory alone for now, ARS Showers and thunderstorms will increase across portions of the Mid-South tonight as a cold front slowly moves into the area.

Temperatures will trend cooler as an onshore component to surface flow builds, culminating in the passage of a frontal system with light rain late in the week. High pressure will be nearly directly overhead today providing for a fair weather day with lighter winds and and near normal temperatures. The center of the high slides to our southeast a bit this afternoon.
Discussion: Currently there are some weak radar returns present across the eastern Tennessee Valley, but with how dry the lower levels of the atmosphere are most of this is likely falling as virga. Strongest winds are expected in the higher terrain of the southern Appalachian Mountains. These storms and the generally overcast skies for much of the day will keep temperatures in check, and about 5-10 degrees cooler than what we experienced yesterday.

A mature surface cyclone is expected to move from the Upper Midwest into the Great Lakes.
- Colder weekend with highs only in the 40s Fri/Sat and at or below freezing lows Sat/Sun. The low will make steady progress east today as a 300 mb 100+ kt eastward moving jet gives it a push. on the backside of the low. Most of the low level forcing is in the south while the initial slug of low level thermodynamics (850 mb WAA) also suggested to stay south (shifting west-east across IA and northern IL). This trend continues to paint the higher rain chances locally along/south of I-90, decreasing with lower QPF moving north of there. Morning lows Fri in the mid 30s with at or below freezing favored Sat and Sun mornings.
