1056 PM EST Mon Nov 11 2024 * Scattered rain showers will occur this evening in northern PA along a secondary cold front. * Gusty winds in the wake of the cold front overnight into Tuesday will accompany much cooler temperatures that will stick around for the middle of the week.
307 AM EST Tue Nov 12 2024 - Cooler conditions on Tuesday in the wake of cold frontal passage.
Currently - A nebulous pressure field blankets our area due to a remnant low in the central Gulf of Mexico, troughing along the Atlantic Coast, the Atlantic Ridge off to our east, and a dying lower level trough across our area. Short Term Update - The overall flow across the Keys is expected to become dominated by weak ridging reaching down the Florida Peninsula. This is complicated combination of the remnants of Rafael continuing to fester in the central Gulf of Mexico, a mid latitude low along the northeast Atlantic Coast, and the Atlantic ridge off to our east.
This front is expected to weaken/diminish later this morning, as a large dome of high pressure builds eastward across the upper MS Valley/Great Lakes states. With drier air out of the N/NE filtering into the area, mostly sunny skies should prevail later today as an upper ridge pattern translates eastward over the Midwest/OH valley areas. Given a minimal influx of cooler air, afternoon highs look to climb predom into the lower/mid 70s.
Cooler today along with lingering north breezes following the passage of a cold front overnight.
10 of an inch in the lower elevations and up to 0.

1052 PM CST Mon Nov 11 2024 (Tonight through Tuesday) Cold front continues to slowly push southward and is currently bisecting the area. It will get another push from a secondary cold front currently approaching the Ohio Valley, but will eventually stall over Lower Alabama tomorrow. There are some low probabilities for fog in our far southern counties with the higher dew points south of the front. Ridging will temporarily build in at mid and upper levels ahead of the next trough over the western CONUS.
1053 PM CST Mon Nov 11 2024 Updated at 1041 PM CST Mon Nov 11 2024 - Breezy conditions are possible Tuesday afternoon and evening, especially near the higher elevations.
This will pump up a downstream ridge over the Mississippi River Valley and Gulf of Mexico, which will extend over the Florida peninsula.
1223 AM MST Tue Nov 12 2024 - Seasonable but cooler temperatures across the Cowboy State today as a quick moving system brings chances for rain/snow this afternoon/evening.
(Today and tonight) Key Message: Cooler temperatures and dry weather expected today.
600 AM EST Tue Nov 12 2024 - Cooler conditions today in the wake of cold frontal passage.
644 AM EST Tue Nov 12 2024 - Cooler over the next few days closer to seasonable normals with dry conditions today into the first part of Wednesday.
Gusts of 45-55 mph over south-central SD - Cold frontal passage this afternoon and night, with gusty northwest winds up to 40 mph and scattered rain/snow showers Latest analysis shows southwesterly flow aloft over the forecast area as the upper ridge shifts off to the east and an upper trough, currently over wrn MT/ern ID/UT, approaches from the west. At the surface, the forecast area is located between high pressure centered over the Great Lakes, and a trough extending southward into ern MT/WY from a low in northern Saskatchewan. As the upper trough crosses the area, there is a chance for light precipitation this afternoon and evening. A mix of light rain/snow is possible over northeastern Wyoming with minor localized snow accumulations possible in the higher elevations of the Black Hills.
Clear skies continue to persist across the region, although the weather pattern is in a transition from ridging that is getting squeezed east of the region by a upper level low that is centered across the Great Basin early this morning. While skies will remain mostly clear throughout the day today, high temperatures will be 5-10 degrees cooler than yesterday due to this trough overhead.
The cloud cover has a high probability (80+%) that much of the northern half remains in the 40s today with the south half getting into the low 50s.
A weak cold front is expected to push through overnight which will help to cool us down a few degrees but still staying above average. This will pump up a downstream ridge over the Mississippi River Valley and Gulf of Mexico, which will extend over the Florida peninsula. The disturbance will move over the plains on Wednesday with the downstream ridge shifting to the eastern seaboard.
520 AM EST Tue Nov 12 2024 With the cold front through the area, northwest flow will bring cold air into the region as high pressure settles in.
(Today through Wednesday) Ridging builds in across the region today into early tomorrow leading to generally dry conditions for the area. A deep trough will move through the Plains and into the MS Valley. With the deepening trough, we should start to see the advection of moisture from the Gulf through the day on Wednesday. This moisture advection will result in increased rain chances initially along what will now be the effective warm front through the evening on Wednesday before the main frontal boundary comes in later.
617 AM EST Tue Nov 12 2024 High pressure will build into the Great Lakes today, with dry conditions prevailing across the region through Wednesday.
For Wednesday a mid-upper level trough will progress eastward through the Southern Plains and eject a cold front into Texas. 2" at the closest proximity of Rafael's remnant before dry air behind the cold front moves in. Highs for Wednesday will be warmer before the arrival of the cold front.
Mondayâs cold frontal passage brought precipitation, cooler air and strong winds to Central California. The cold front arrived into the area at around Noon and crossed most of the district before midnight. High-Res short-range Ensemble Mean upper-air analysis places Central California under a ridge pattern as the disturbance now moves toward the Four Corners area. These values represent the area along the Highway 99 corridor with percentages closer to 5-10% along Interstate 5. Only uncertainty with fog development will be the low clouds over the same area near Highway 99. As noted, weak ridge expected today and Wednesday with a weak disturbance riding over the ridge later on Wednesday.
543 AM CST Tue Nov 12 2024 (Today through Wednesday) Warm conditions continue today, with high temperatures forecast in the low to mid 80s for most areas, upper 80s near the Rio Grande. An associated Pacific cold front will move across south-central Texas on Wednesday.
- This afternoon will be warmer with breezy south winds. - Slightly cooler temperatures will follow a cold frontal passage on Wednesday.
Short Term (Today and Wednesday) The post-frontal airmass currently in place is bringing chilly temperatures this morning, with lows hovering around freezing. The upper level pattern currently consists of low-amplitude ridging over the central Plains with a longwave trough beginning to dig into the Rockies. 50" range with the highest values expected in western Iowa.
558 AM CST Tue Nov 12 2024 (Tuesday through Wednesday) Weak ridging aloft to maintain dry and stable conditions across the region today. Pattern to shift overnight as the remnants of Rafael in the Gulf of Mexico translate westward in the form of an easterly wave that will interact with a cold front approaching from the west. Showers and isolated thunderstorms to continue through much of the day Wednesday as an upper-trough swings east across the Midwest and drives the cold front eastward across the area.
Temperatures today will only be slightly warmer with a brief pause in widespread rain chances. A mix of sun and clouds today will see temperatures bump up a few degrees today from yesterday as the next upper trough bringing more rain deepens over open water to our west. Cooler, drier air in the wake of the surface cold front that pushed through yesterday will linger at the surface today. Once again, the North Bay is expected to see the highest totals with help from orographic effects.
411 AM PST Tue Nov 12 2024 Today will be cooler with locally gusty north to northeast winds along and below the coastal slopes of the mountains.
high clouds ahead of a low pressure system currently over the Desert Southwest will remain common across the majority of the CWA through this afternoon. with the warmer temps into southeast Oklahoma where the cloud cover this afternoon is expected to be the thinnest.
618 AM EST Tue Nov 12 2024 (Today and tonight) Key Message: Cooler temperatures and dry weather expected today.

954 AM EST Tue Nov 12 2024 A cold front will move offshore this morning, with dry and cool high pressure then building across the Carolinas from the north through Wednesday, moving offshore Wednesday night.
- WED RAIN CHANCES: most will get wet, but local accumulations on the low end (1/4" or less) Sort of 2 main focuses for rain production Wed, associated with an upper level trough moving eastward from the west coast today, to across the upper/mid mississippi river valleys by 00z Thu. GEFS/EPS members favor tracking the low across IA, although there are disagreements on placement between and within each model. - MILDER WEEKEND AHEAD The GEFS and EPS build an upper level ridge across the upper mississippi river valley starting Thu, amplifying it moving into the weekend but also shifting the ridge axis east over the New England states by 00z Mon. The EPS has been a bit a stronger with the ridge compared to the GEFS, evidenced via WPC clusters.
641 AM EST Tue Nov 12 2024 A cold front will move offshore this morning, with dry and cool high pressure then building across the Carolinas from the north through Wednesday, moving offshore Wednesday night.

706 AM EST Tue Nov 12 2024 A strong cold front crosses the region this morning.
Mild temperatures and breezy winds are expected today, then warmer than normal temperatures return through the remainder of the work week. A pattern switch is likely this weekend which will bring cooler temperatures and chances for valley rain and mountain snow showers.
High pressure remains docked east of Bermuda, with a series of frontal boundaries spaced out to the west. High pressure building in the wake of the frontal passage will promote a tightened pressure gradient and associated windy conditions for Wednesday into Wednesday night.
510 AM CST Tue Nov 12 2024 (Today through Wednesday Night) To begin the period, an upper level trough is situated over the western US with AR under a ridge of high pressure. This pattern will be short lived as that trough continues to push towards the east. A cold front will move into the state Wednesday bringing the next chance for rain across the state. As mentioned above, temperatures will mostly be normal for this time of the year with highs in the lower 60s to lowers 70s. Overnight lows are expected to drop into the lower 40s to lower 50s through the period.

Upper-level ridging will shift eastward through the middle of the country today. An upper trough is moving eastward across the Great Basin early this morning. At the surface, high pressure will move into the eastern Great Lakes. Stronger flow aloft will help to deepen a lee trough in the High Plains today and that will lead to a tighter pressure gradient across the Central and Eastern Plains. As the Great Basin upper trough moves into the Plains later tonight, large-scale ascent ahead of the trough will lead to widespread showers. Broad upper ridging develops for the remainder of the week and into the weekend.
613 AM EST Tue Nov 12 2024 A cold front will move offshore this morning, with dry and cool high pressure then building across the Carolinas from the north through Wednesday, moving offshore Wednesday night.
GOES-16 upper level water vapor imagery shows yesterday's wave moving to the east, while ridging builds in from the west. Also clear in this image is a digging trough over the western United States. Temperatures will be cooler than Tuesday with highs in the mid 40s to 50s, but are expected to remain warm enough that all precipitation will fall as rain.
417 AM EST Tue Nov 12 2024 A cold front will move offshore this morning, with dry and cool high pressure then building across the Carolinas from the north through Wednesday, moving offshore Wednesday night.
High pressure centered north across Minnesota and Wisconsin has kept the area quiet and clear overnight. Temperatures will warm into the low 50s this afternoon, near to just above seasonal average for this time of year. At the same time winds increase as the pressure gradient tightens ahead of a deepening western US trough. By early Wednesday morning the aforementioned western US trough will have lifted across the central plains and into Iowa.
621 AM EST Tue Nov 12 2024 - Quiet and Seasonable Through Wednesday - One main chance for precipitation: Wed night through Thurs night - Temperatures near to slightly above normal - Quiet and Seasonable Through Wednesday Subsidence and resultant drying from the arrival of surface and upper-level ridging brings plenty of sunshine to West Michigan today. However, the persistence of thermal troughing keeps high temperatures in the mid to upper forties. Conditions look to be dry for the daylight hours of Wednesday as dry air and the influence of surface and upper-level ridging persist.
510 AM CST Tue Nov 12 2024 - This afternoon will be warmer with breezy south winds. - Slightly cooler temperatures will follow a cold frontal passage on Wednesday.
551 AM CST Tue Nov 12 2024 (Today through Wednesday) An upper-level ridge over Northern Mexico will continue to support warm temperatures and light to moderate easterly winds.
(Today through Wednesday) An upper-level ridge over Northern Mexico will continue to support warm temperatures and light to moderate easterly winds.
500 AM MST Tue Nov 12 2024 - Seasonable but cooler temperatures across the Cowboy State today as a quick moving system brings chances for rain/snow this afternoon/evening. Temperatures warm up back up slightly for the second half of the week as some ridging builds over the region.
This low is still interacting with the strong ridge over the gulf south causing winds to remain elevated along the coast and offshore. All severe weather variables will be on the table with hail being the lowest risk. But this ends late Wed into Thu and there will be a timing issue with this as high tide comes late Wed and this is as we are getting SE winds on the east side of the old remnants and ahead of the cold front.
507 AM CST Tue Nov 12 2024 (Today through Wednesday) Ridging builds in across the region today into early tomorrow leading to generally dry conditions for the area. A deep trough will move through the Plains and into the MS Valley. With the deepening trough, we should start to see the advection of moisture from the Gulf through the day on Wednesday. This moisture advection will result in increased rain chances initially along what will now be the effective warm front through the evening on Wednesday before the main frontal boundary comes in later.
A weak dry cold front will move south through the area late tonight into early Tuesday, ushering in a cooler and drier air mass. Strong high pressure over the Northeast will build south through the Carolinas into Georgia through mid-week.
1132 AM EST Tue Nov 12 2024 - Cooler over the next few days closer to seasonable normals with dry conditions today into the first part of Wednesday.
1156 AM CST Tue Nov 12 2024 (Today through Wednesday Night) To begin the period, an upper level trough is situated over the western US with AR under a ridge of high pressure. This pattern will be short lived as that trough continues to push towards the east. A cold front will move into the state Wednesday bringing the next chance for rain across the state.

Overnight lows are expected to drop into the lower 40s to lower 50s through the period.
322 PM EST Tue Nov 12 2024 Dry weather will continue tonight through Wednesday as high pressure moves from the Great Lakes to New England.
Following a cold front earlier today that brought widespread rain and snow with precipitation amounts around a T-0. Dry conditions will continue heading into early Wednesday as a brief ridge of high pressure builds back in overhead while another H5 low continues to move onshore to British Columbia and PacNW. Given W/SW moisture transport with this trough, best chances for accumulating snow will remain confined to the Wood River Valley, Sawtooth Valley, and Island Park regions. 40" range in the mountains, again locally higher across the highest elevations of the Sawtooths around 0. Given the influence of SW flow back on Wednesday with a ridge axis of high pressure shifting east, temperatures will be slightly warmer for most with highs on Wednesday back in the mid 30s to low 50s with overnight lows Wednesday night in the 20s/30s.
After a cold front passage tonight, the Borderland will see cooler temperatures, calm winds, and clear skies on Wednesday.
It will be cool with lows in the 40s, but still a few degrees warmer than normal for this time of year. A deep trough from the Four Corners will plow eastward, spinning up a low pressure system and cold front.
Mid-day water vapor imagery shows a deep mid-level trough across the Inner-Mountain West. Despite the wind shift the air behind the front will be no cooler than ahead of it. In fact, the heavy cloud cover will help keep temperatures a few degrees warmer Wednesday night than tonight. Delia With the exit of the mid-level trough a ridge will build into the central CONUS in it's wake. During the end of the work week a deep mid-level trough will move onshore along the West Coast. All ensemble members show the trough deepening and eventually developing into a split stream system over the western CONUS by the end of the weekend. The northern stream trough will slide through the Great Lakes Region, bringing a weakening surface front into the forecast area during the end of the weekend/start of the work week.
902 AM PST Tue Nov 12 2024 Temperatures today will only be slightly warmer with a brief pause in widespread rain chances. A mix of sun and clouds today will see temperatures bump up a few degrees today from yesterday as the next upper trough bringing more rain deepens over open water to our west. Cooler, drier air in the wake of the surface cold front that pushed through yesterday will linger at the surface today. Once again, the North Bay is expected to see the highest totals with help from orographic effects.
1110 AM CST Tue Nov 12 2024 (Rest of Today) Upper ridging will continue to build just to our west today as high pressure slowly shifts east over the Great Lakes.
312 PM EST Tue Nov 12 2024 High pressure will build across the area through late Wednesday.
Discussion: Dry weather will continue for tonight and the first half of tomorrow as a high pressure ridge overhead today will shift eastward through the period. As the mid/upper level ridge axis shifts east of the Appalachians tomorrow morning, mi/dhigh clouds will start to increase from the SW, and a chance of rain will enter our SW Plateau counties in the afternoon, spreading eastward into the Valley by 00Z.
(Rest of today through Wednesday) A weakening cold front will drift southward across the Florida peninsula through the short term, while mid-level ridging prevails aloft. The frontal approach will help enhance the low- level moisture profile over the next couple of days.
(Today through Wednesday) Warm conditions continue today, with high temperatures forecast in the low to mid 80s for most areas, upper 80s near the Rio Grande. An associated Pacific cold front will move across south-central Texas on Wednesday.
The next batch of rain will be associated with an approaching trough Wednesday into Wednesday night. A rather deep upper trough will eject over the central US and into the midwest by Wednesday. This upper trough will drag a cold front into the southeast. PWATS ahead of this trough will climb to around 2 inches as southwesterly flow surges Gulf moisture northward. A warm front will lift northward throughout the day on Wednesday likely leading to scattered showers and storms across the area.
1234 PM EST Tue Nov 12 2024 High pressure will build into the Great Lakes today, with dry conditions prevailing across the region through Wednesday.
High pressure overhead today will depart to our east tomorrow as a trough across the Rockies progresses east through the Mississippi Valley. Southerly flow ahead of the trough will promote moisture advection into our region with precipitable water values of around 1. End of the week looks quite nice with high pressure overhead and temperatures a little above normal. Models advertise troughing moving into the western U.
/44/ (Tuesday through Wednesday) Weak ridging aloft to maintain dry and stable conditions across the region today. Pattern to shift overnight as the remnants of Rafael in the Gulf of Mexico translate westward in the form of an easterly wave that will interact with a cold front approaching from the west. Showers and isolated thunderstorms to continue through much of the day Wednesday as an upper-trough swings east across the Midwest and drives the cold front eastward across the area.
128 PM EST Tue Nov 12 2024 A cold front will move offshore this morning, with dry and cool high pressure then building across the Carolinas from the north through Wednesday, moving offshore Wednesday night.
