Breezy north winds will make it feel cooler even though it will be sunny.
1113 AM CST Tue Nov 19 2024 Updated at 1112 AM CST Tue Nov 19 2024 - There is good (60-80 percent) confidence that temperatures will fall to at or below freezing across areas along and north of I-20 Wednesday morning. (Today through Wednesday afternoon) A cold front will make its way through the area later this morning and shift winds out of the north to northwest.
1100 AM CST Tue Nov 19 2024 (Rest of Today) Much of the shower activity from earlier has tapered off to the east this Tue morning, as a cold front approaches NW AL. Lingering moisture below H7 will also keep cloudy skies in place for the remainder of today, as a broad upper low/trough pattern traverses across much of the eastern CONUS. Temps likewise in the lower/mid 60s will struggle to surpass the upper 60s across the east to the lower 70s closer to NW AL.
Otherwise, clear skies and mild temperatures are expected today with northwesterly winds increasing as the next cold front passes through the region.
High pressure centered northeast of the Bahamas is sliding eastward in response to an approaching cold front. Ahead of this front we are expecting a pre-frontal trough to move through. This will not only maintain fresh to occasionally strong breezes across the area, but a cooler air mass and less humid conditions will follow the frontal passage.
- Cold temperatures are forecast for tonight with most areas dropping to or below freezing. Mainly light winds will continue this afternoon with temperatures cooler than yesterday with highs mainly in the 50s. The coldest temperatures so far this season are expected for the Panhandles tonight with widespread subfreezing temperatures by early tomorrow morning. After the colder start to the day, winds will turn to out of the south which will aid in bringing back a warmer airmass for the rest of the day. Another cooler night is likely on Wednesday night, but temperatures should remain a few degrees warmer than they will be tonight.
1242 PM EST Tue Nov 19 2024 Rain with a cold front today. A reinforcing cold front Wednesday brings much colder air. A cold front will continue to provide a band of showers moving eastward across the area this afternoon. With some slight cooling in the lower levels, drizzle becomes a possibility tonight. A strong reinforcing cold front will then push through on Wednesday. By Wednesday morning, a broad upper-level low/trough over the Midwest will extend southeast across the OH Valley into WV. An associated strong vorticity maximum will push a couple of cold fronts across the area on Wednesday.
Conditions have remained relatively mild behind the last front with temperatures this afternoon forecast to reach just a couple degrees above average for this time of year with highs in the low to middle 80s. Then, much cooler weather will filter in behind the front!

A powerful upper low to the west of Vancouver Island is pumping ample moisture into the Pacific NW, the majority of which will be captured by the mountains of Oregon and Washington tomorrow.
1128 AM CST Tue Nov 19 2024 - Dry forecast for the next 7 days - Below normal temperatures for the second half of the week - Warming trend into the weekend As of 3 AM, much quieter conditions have settled into the region with the midlevel trough, responsible for yesterday's showers, now across southern MN. Cloud cover will once again be on the increase this afternoon as a secondary midlevel trough slides across the central Plains. Afternoon temperatures will range from the upper 40s across central KS to the low 60s in southeast KS. Temperatures will remain near to slightly below normal through weeks end with highs generally in the low to mid 50s.
The low pressure system currently sits over Minnesota at the surface, and tilting back to Montana through the upper levels. A Stationary front sits on the backside of the low in northwest North Dakota. There are two distinct bands of snow right now, both angled northwest to southeast, rotating with the low. Overnight the low pressure system will continue to linger around Minnesota, continuing to produce snow in North Dakota. The rest of the week will be much cooler than we are used to.
Updated at 226 PM CST Tue Nov 19 2024 - A weak cold front will bring cooler temperatures from this evening through the end of the week. As this occurs winds will eventually decrease across the west and with dry air in place and clear skies, temperatures will fall to near or below freezing across portions of western and northern Oklahoma, where a freeze has already occurred. Further east and south some locations may approach freezing, but not quite low enough to warrant a freeze warning at this point.
As this system continues to move closer to the coast, the cooler waters should help weaken everything so widespread storms are not expected.
753 PM EDT Mon Mar 24 2025 Weak high pressure will build into the area Tuesday.
An upper low was over Northeastern Lake Michigan with broad troughing extending down toward the Northern Gulf of Mexico while amplified mid-level ridging was centered over the Desert Southwest. An amplified pattern will persist across the country as deep troughing extends from over the Eastern Great Lakes southward toward the Northern Florida Peninsula while broad rigging will extend from over Northwest Mexico northwest to over much of the Pacific Northwest. Low temperatures will range from the lower 40s east and northeast to readings around 50 far south. Mid-level troughing will persist over much of the Ohio and Tennessee Valley Regions on Tuesday while longwave ridging continues to build from over Northern Mexico extending northwest to over Washington State. High temperatures will range from the lower 70s far east to readings around 80 west.
High pressure builds into the region through at least the middle of the week, bringing a significant warming trend to the region. A cold front will bring the end of this warming trend and much more seasonable temperatures later in the week.
High pressure slides east tonight as low pressure lifts a warm front across the area. After the warmup into the 70s to end the week/extend over the weekend, the aforementioned system's passage should return dry weather and seasonally cooler temps in the 60s to begin the new week.

The cold front remains to our west this evening, but is starting to make some slow progress from the upstate toward the south and east. Broad upper trough over the eastern CONUS with drier air filtering in behind the cold front as HREF mean indicates PWATs remain below 0. Temperatures warmer tomorrow with more sun through the day with highs in the mid to upper 80s.
Water vapor imagery suggests these storms are within the core of the trough axis, accompanied by steep mid-level lapse rates and plenty of bulk shear. The overnight forecast calls for nil rain chances, lows in the lower 70s, and light east to southeast breezes. From synopsis, weak low level ridging will dominate through the first half of the week, keeping breezes light and largely easterly.

Winds may aid in drying pavements off before temperatures drop below freezing tonight.
The batch of clouds sliding in from the NW on the back of a broad trough should scrape the northern part of the CWA, leaving us with mostly sunny skies today.
The models work to get a little wind to transport the warmer dew points northward, but considering the fact that we have more calm reports than SE wind right now, I am thinking this process will be slow for hours yet. /24/ (This evening through Tuesday Night) Upper level ridging will sustain quiet conditions for the better part of the next 36 hours. Tuesday night will be similar to tonight, if a few degrees warmer, with increasing surface moisture to the south and building cloud cover aloft from the north and west, ahead of our next rainfall chances.
1243 AM CDT Tue Mar 25 2025 (Tonight through Tuesday night) Overall a quiet afternoon ongoing with temps mostly in the low to mid 80s and SE to easterly winds. A weak cold front that has moved through STX over the day has slowed in momentum as it approached the CWA boarder.
Dry weather and clearing skies will be in place throughout the day as the influence of high pressure and dry air dominates the weather pattern today, with a slight chance for light showers over north central Florida this afternoon.

312 AM EDT Tue Mar 25 2025 An unsettled pattern is expected to bring scattered rain and snow showers along with cooler weather through at least the middle of the week. A few scattered showers have also developed across parts of the Finger Lakes Region ahead of an approaching trough. This trough is expected to kick off some additional scattered showers tonight, potentially mixing with or changing to snow showers later tonight, especially across Oneida County. The trough will remain overhead on Tuesday, which will bring more scattered showers. Much of the same is expected Tuesday night with our region still being influenced by the longwave trough.
930 PM PDT Mon Mar 24 2025 A ridge of high pressure will continue to provide warm weather through Tuesday with coastal low clouds and fog at times.
Northwest flow prevails at the H5 level with persistent ridging in place across the western CONUS and longwave troughing over the Hudson Bay region. The first of these troughs will bring a chance for light precipitation to eastern North Dakota today.
An upper level ridge continues to build over the western CONUS, with an upper low over the Great Lakes Region, placing the area in northwesterly flow aloft. With afternoon highs in the upper 60s to low 70s, relative humidity values will drop into the 20-30% range (with the lower end of that over the eastern Ozarks), with breezy northwest winds gusting up to 20-25mph. Afternoon highs will top out in the mid 60s to low 70s, with the higher temperatures towards the MO/AR border. As the upper level ridge continues to build over the region, there is fairly high confidence in above normal temperatures mid week through the end of the week.
Ample sunshine is anticipated for this afternoon with temps looking to warm nicely into the mid 70s to the lower 80s across C AL. A reinforcing cold front will move through tonight. While no precip it anticipated with it, look for NWRLY winds on Wed with temps a few degrees milder for highs as surface ridging builds over E Conus.

It's a pretty messy, unsettled weather scenario with temperatures largely just cold enough for snow showers, except in the lowest elevations. A weak wave will move through increasing precipitation chances along slopes and ridges today before the upper low tracks over the region by Wednesday.
The 25/00Z H500 hand analysis map has a strong ridge located along the Pacific coast line of NOAM. with troughing over the EPAC and eastern NOAM. This ridge will be squeezed over the spine of the Rockies over the next few days and lead to anomalous warmth building over the region. Ensemble H700 temps are signaling a 10+ year return interval under this ridge which will equate to max temperatures some 10 to 20 degrees above normal going into the mid week period.
Near-record high temperatures are expected again today with a strong area of high pressure in place. A weak disturbance move through on Wednesday, leading to a slight dip in temperatures and some isolated showers to the high terrain.

208 AM MST Tue Mar 25 2025 Unseasonably strong high pressure over the region will continue to bring record to near record breaking temperatures today into Wednesday.
224 AM PDT Tue Mar 25 2025 Dry and mild weather continues today before a transition toward cooler and periodically more active weather from Wednesday onward. Clear skies persist once again this morning as ridging aloft remains in place. While troughing will begin to impact the region by midday Wednesday, another mild overnight period will keep high temperatures into Wednesday comparably cooler, but still above normal for late March. Initial impacts from, the approaching trough will be tied to increasing southerly winds through the afternoon. The introduction of this long wave trough will induce broad west- northwesterly into interior NorCal from Wednesday into the weekend. Despite this, thunderstorm activity is expected to remain conditionally dependent upon proximal forcing and cooling aloft as the trough nears the NorCal coast.
The low clouds across the north should exit the area by mid- morning.
Should see mixed showers moving southeastward through the morning, but only the highest radar returns reaching the ground. Northwest flow prevails at the H5 level with persistent ridging in place across the western CONUS and longwave troughing over the Hudson Bay region. The first of these troughs will bring a chance for light precipitation to eastern North Dakota today.
Unseasonably strong high pressure over the region will continue to bring record to near record breaking temperatures today into Wednesday.
* Instability will be on the rise the next few days with the warmer temperatures, though Central Valley locations will likely be well capped. The ridge overhead is primarily bringing temperatures 10 to 15 degrees above seasonal norms. The ridge will slide east tomorrow, but not before another warm day tomorrow. In the higher terrain above the inversion, however, there remains less than 20% thunderstorm chance.
We were able to radiate quickly in the evening when the skies were clear, so our lows dropped into the lower 20s in our north and along I-94 inland from Lake Michigan. East central WI will remain in the lower 40s, thanks to more clouds and colder air aloft due to an upper trough swinging through.
A weak wave will move through increasing precipitation chances along slopes and ridges today before the upper low tracks over the region by Wednesday.
High temperatures to range from near 50 across the south - where rain will occur and clouds will be thickest, to the lower and middle 50s elsewhere.
(This afternoon through Wednesday) Longwave troughing is extending south from eastern Canada into the Eastern Seaboard. Longwave ridging is building across the western CONUS. At the surface, high pressure will begin to build south from the Upper Plains tonight, so we will have weak northeasterly surface winds overnight, and I leaned towards the cooler guidance for lows. Temperatures should fall into the lower 40s northeast to lower 50s southeast. Ridging will continue to build over the area tomorrow with flow remaining from the northwest.
330 PM CDT Tue Mar 25 2025 - There is a 20-30 percent chance of light rain mainly east of the Buffalo Ridge in southwest Minnesota late this afternoon.
1225 PM CDT Tue Mar 25 2025 (Rest of Today and Tonight) Tranquil weather across the Tennessee Valley late this morning, with high pressure promoting sunny/dry conditions. A dry cold front will bring some breezy winds between 10-20 MPH later this afternoon and evening, but the lack of moisture will prevent the formation of any light showers. These winds will become light out of the north, allowing temperatures to drop back into the low to mid 40s.
