A low- amplitude mid-level ridge will develop to the west of the region today, and as weak southerly return flow resumes, today will mark the beginning of a warming and drying trend. Despite lingering cloud cover for most, temperatures today will top out about 5 degrees warmer than yesterday, with lower 60s for most locations, 50s in the mountains, and 70s along portions of the Rio Grande. On Wednesday, the aforementioned ridge will shift eastward across West Texas, with clearing skies and southerly surface flow yielding a continuation of the warming trend as highs Wednesday reach the upper 60s and lower 70s, near or even a degree or two above normal in spots.
Highs will be above normal today reaching the mid to upper-fifties, however it would not be surprising to see a few areas reach the low sixties given the ample insolation today. High pressure centered over the Ohio river valley this morning is keeping conditions tranquil.
557 AM CST Tue Nov 14 2023 Another cloudy, mostly dry, and seasonable day is on the horizon a high pressure continues dominates our weather pattern today. Tomorrow, a low pressure to our south will bring rain chances back to the forecast for areas in northern Mississippi.
Though mixing will be fairly shallow; only to around 925-900 mb, gusts to 25 to 35 mph will occur over most of the CWA, with perhaps a few gusts near 40 mph in the higher elevations of north central WI. The pressure gradient will slacken as a weakening cold front pushes into the region late tonight into Wednesday morning.
A shallow mid level trough over Central TX shifts east this morning and sharpens into more of a closed low over SE TX/SW LA by midday. With the upper trough/low development just to the east this morning, there should be a good subsidence signal and a drying wedge to lower dew points and remove the overcast conditions by midday over the I- 35 corridor. So look for slightly below normal min temps tonight with the light winds and lower dew points, then a slightly warmer than normal max temp and mostly sunny skies for most areas Wednesday.
903 AM EST Tue Nov 14 2023 High pressure will remain in place across the region through mid week, leading to dry and seasonably mild conditions. Cooler conditions arrive for the weekend. High pressure will allow for dry conditions through the near term. The high pressure will slide off to the east Tuesday night and Wednesday.
(Today through Wednesday) High pressure will continue across much of north and central Georgia today. A low pressure center has developed south of LA and will be the main weather maker for the CWA for the short term period.
611 AM EST Tue Nov 14 2023 VFR conditions will prevail through the TAF period as high pressure dominates the weather locally. Light west to northwest winds will shift to the south and southeast throughout the day as the high pressure drifts east in the region.
639 AM EST Tue Nov 14 2023 High pressure will remain in place across the region through mid week, leading to dry and seasonably mild conditions. Cooler conditions arrive for the weekend. The high pressure will slide off to the east Tuesday night and Wednesday.
230 AM MST Tue Nov 14 2023 Upper ridge will move a bit south tomorrow and Wednesday with zonal flow across the central plains.
645 AM EST Tue Nov 14 2023 Dry high pressure to prevail for most areas through Wednesday. Low pressure passing by to the east will increase rain chances mid to late week with warming temperatures. A cold front moves through for the weekend with a return to cool and dry conditions. Dry weather should continue with high pressure prevailing. Highs in the low-mid 60s with lows in the upper 40s-lower 50s near the coast. Lows warm further into the low-mid 50s. A cold front moving through Sat will cause things to dry out once more for the weekend with a slow transition to high pressure. High confidence in VFR conditions across SE NC and NE SC through 12Z/15 as high pressure prevails.
A thermal ridge presently centered over eastern North Dakota will continue breaking down through the day today. This, along with a weak cold frontal boundary passing through, will help limit high temperatures today to the upper 40s in the northwest to around 60 near the ND/SD border.
618 AM EST Tue Nov 14 2023 Aviation High pressure centered over the Ohio river valley this morning is keeping conditions tranquil.
The highest accumulation of rain will reside in the Hwy 84 corridor towards the Pine Belt with mean rain totals > 1 inch.

Ridging aloft overspreads the region tonight and maintains light W- SW surface flow.
Another cloudy, mostly dry, and seasonable day is on the horizon a high pressure continues dominates our weather pattern today. Tomorrow, a low pressure to our south will bring rain chances back to the forecast for areas in northern Mississippi.
thin spots in the high clouds at times will lead to some areas getting more sun than others. Only a little cooler at 925 mb compared to Tuesday and with sun may not notice any appreciable cooling with highs still in the 50s.
936 AM EST Tue Nov 14 2023 High pressure ridging across the area with the stalled boundary to the south and the area of low pressure along the boundary in the northern Gulf of Mexico.
917 AM EST Tue Nov 14 2023 Dry high pressure to prevail for most areas through Wednesday. Low pressure passing by to the east will increase rain chances mid to late week with warming temperatures. A cold front moves through for the weekend with a return to cool and dry conditions. Dry weather should continue with high pressure prevailing. Highs in the low-mid 60s with lows in the upper 40s-lower 50s near the coast. Lows warm further into the low-mid 50s. A cold front moving through Sat will cause things to dry out once more for the weekend with a slow transition to high pressure. High confidence in VFR conditions across SE NC and NE SC through 12Z/15 as high pressure prevails.
525 AM CST Tue Nov 14 2023 (Today) Upper low currently sitting over North Texas will shift eastward during the day today, resulting in clearing skies over the region and near persistent conditions continuing from the previous few days. after a cool start, mild afternoon highs in the lower 70s can be expected for most locations.
438 AM MST Tue Nov 14 2023 Another mild day is expected today, although temperatures will be a few degrees cooler following a weak cold frontal passage this morning. Upper trof crossing the Canadian prairies with a strong mid-level jet, pushing the front through the region with weak cold air advection. While the CAA and pressure rises will increase mixing for today, the weakening pressure gradient as high pressure builds over the state should keep winds in check. The high moves east on Wednesday as the next system begins to take shape to the west.
A low pressure system will bring periods of high elevation snow showers and valley rain showers late Wednesday into the weekend.
513 AM EST Tue Nov 14 2023 Low pressure will exit southeast of the Gulf of Maine today.
With cloud cover decreasing in coverage, expect high temperatures to warm into the low to mid 70s this afternoon. The clearing of skies and decreasing northerly winds will promote radiational cooling processes tonight, which will allow low temperatures to fall into the low to mid 50s region wide. This is about 5 to 8 degrees cooler than low temperatures this past weekend. If you're wondering why: In the same way that cloud cover aids in reflecting the sun's heat away from the earth's surface during the day with only some heat reaching the surface, cloud cover at night can also keep the heat from the earth's surface trapped beneath the cloud layer and result in slightly warmer low temperatures and less variation in the temperature diurnal curve.
Models are likely a bit on the fast side, especially the GFS, and will trend toward the cooler WRF-NAM and short term model blends.
133 PM EST Tue Nov 14 2023 High pressure and dry weather will remain in control through mid week.
Upper low off California will send a lobe northward through Oregon today with a slight chance of rain showers in Harney County late today and this evening, and Baker and Valley Counties tonight.
With high pressure moving in behind the departing storm system that brought rain and cloudy skies to the region, we should see plenty of sunshine through Wednesday. Temperatures may be a hair cooler out west under that extra cloud cover, otherwise, expect highs in the upper 60s to lower 70s this afternoon. Wednesday will be a touch warmer than today as morning cloud cover should not be quite as widespread, allowing temperatures to rise quickly after sunrise. Another gorgeous afternoon with some high clouds here and there along with temperatures in the lower to middle 70s.
The second reason is that we will see some upper-level ridging building back into the region for Wednesday. Wednesday night should see temperatures once again range from the mid 40s to the lower 50s across the region.
1133 AM CST Tue Nov 14 2023 Dry cold front is pushing through central ND and into eastern ND at this time. Temperatures will be a but slower to rise this afternoon behind the cold front with some gusty winds at times as well. A thermal ridge presently centered over eastern North Dakota will continue breaking down through the day today. This, along with a weak cold frontal boundary passing through, will help limit high temperatures today to the upper 40s in the northwest to around 60 near the ND/SD border.
(This evening through Wednesday) An upper level ridge building over the area will continue to bring clear and dry conditions. Gusty southerly winds over the western CWA will gradually diminish through the afternoon as relative low pressure weakens near the Rockies. Wednesday's weather will largely be a repeat of today's with mostly sunny skies and highs generally in the low 70s.
The only adjustments needed were to temperatures, which are slightly cooler due to slightly thicker sky cover than was anticipated. thin spots in the high clouds at times will lead to some areas getting more sun than others. Only a little cooler at 925 mb compared to Tuesday and with sun may not notice any appreciable cooling with highs still in the 50s.
Gusty southerly winds persist through the afternoon with the pressure gradient between a weak trough over the eastern Dakotas and ridging over the eastern Great Lakes only gradually relaxing over the course of the night. For Wednesday, winds will be much lighter as the aforementioned upstream trough slides into the region. A somewhat higher (+10 K) theta-e airmass works just ahead of this trough and results in higher dewpoints compared to today.

245 PM EST Tue Nov 14 2023 Energetic upper level flow tracking across Canada, with the first strong upper level low/PV anomaly currently tracking northeast toward Hudson Bay. This system will drag a weakening cold front into the Central Great Lakes on Wednesday. 925 MB temps progged to reach 10 C by 18z Wednesday suggests highs in the lower 60s, but mixing depths likely come up just short of that level. NAM soundings look too shallow and will skew the forecast toward warmer Euro MOS, which also may be a touch underdone as well (see yesterday's highs vs guidance).
1248 PM EST Tue Nov 14 2023 High pressure will remain in place across the region through mid week, leading to dry and seasonably mild conditions. Cooler conditions arrive for the weekend. High pressure will allow for dry conditions through the near term. The high pressure will slide off to the east Tuesday night and Wednesday.
Finally, a broad quasistationary trough in the southwestern Caribbean Sea continues to spin, with cirrostratus debris clouds being shed northeastward towards the Florida Keys. Forecast soundings show substantial deep tropospheric moistening after midnight tonight, as the aforementioned Gulf low and upper-level trough continue to slide slowly southeastward.
1125 AM CST Tue Nov 14 2023 Another cloudy, mostly dry, and seasonable day is on the horizon a high pressure continues dominates our weather pattern today. Tomorrow, a low pressure to our south will bring rain chances back to the forecast for areas in northern Mississippi.
Ridging should gradually bring temperatures up through the rest of the week. The weekend will feature a coastal low and a cold front from Canada, bringing some rain into the forecast.
Subsidence is present across lower Michigan with upper-level ridging remaining in place. At the surface we remain under the influence of a anticyclone to our southeast.
Water vapor imagery depicts a low over Canada and a low off the coast of northern California this afternoon, leaving Colorado in west-southwesterly flow aloft as ridging builds in from our west. Dewpoints are in the low teens and single digits, as dry westerly winds continue across the area. Temperatures will range from teens for the high country, to 20s for our far eastern plains, with 30s and even some low 40s for our mountain adjacent plains. Wednesday will be slightly cooler than today, though still expecting daytime highs to be around 10 degrees above seasonal norms for most locations. Our flow becomes more southwesterly aloft, allowing for an increase in cloud cover over the high country, and an increase in relative humidity values over our plains.
1036 AM EST Tue Nov 14 2023 High pressure will remain in place across the region through mid week, leading to dry and seasonably mild conditions. Cooler conditions arrive for the weekend. High pressure will allow for dry conditions through the near term. The high pressure will slide off to the east Tuesday night and Wednesday.
141 PM EST Tue Nov 14 2023 High pressure centered over Pennsylvania this evening will gradually drift off the East Coast late tonight and Wednesday.
Pinched upper ridging will be pushed east as a closed low develops over the Gulf. High pressure will continue to dominate the northeast and east coast. This will help keep overnight lows a bit warmer compared to this morning.
1129 AM CST Tue Nov 14 2023 (Today through Wednesday) Current water vapor satellite imagery positions 500 mb low pressure centered over the Lone Star State, with drier air steadily moving into the BRO CWFA from the west. As the aforementioned low steadily moves east into the Florida Panhandle, a mid-level ridge of high pressure will build over Mexico in its wake.
(Tonight) Dense high clouds remain in place across the region this afternoon as an area of low pressure passes well to our south along the MS/AL/FL Gulf Coast. This evening and overnight, the slow-moving mid/upper level trough will begin to amplify as it pivots into the western Florida Panhandle. The dense cloud cover will limit our cooling potential, with lows dropping into the low to mid 50s in most locations.
RW (Today through Wednesday) High pressure will continue across much of north and central Georgia today. A low pressure center has developed south of LA and will be the main weather maker for the CWA for the short term period.

Southerly winds have returned with temperatures in the lower 70s in many locations.
1230 PM EST Tue Nov 14 2023 Dry high pressure to prevail for most areas through Wednesday. Low pressure passing by to the east will increase rain chances mid to late week with warming temperatures. A cold front moves through for the weekend with a return to cool and dry conditions. Dry weather should continue with high pressure prevailing. Highs in the low-mid 60s with lows in the upper 40s-lower 50s near the coast. Lows warm further into the low-mid 50s. A cold front moving through Sat will cause things to dry out once more for the weekend with a slow transition to high pressure.
A building ridge will shift into our region through the next 24 hours, driving temperatures into the upper 60s today and lower 70s tomorrow. Most location will drop into the mid to upper 40s with a few locations along the Red River in the lower 40s. /NEW/ /Wednesday Night Onward/ The aforementioned ridge will continue to persist overtop the region through mid-late week.

Beginning Wednesday evening, a more active weather pattern will bring cooler and more unsettled weather that is forecast to last through the weekend.
550 PM CST Tue Nov 14 2023 Tonight-Wednesday night: As the upper low swings southeast, expect the closed low to become more vertically stacked over the sfc cyclone/baroclinic zone along the northern Gulf Coast. Lows will be some 5-10 degrees above normal in the low-mid 50s & highs some 10-15 degrees below normal in the upper 50s east of I-55 to low 60s to the west & in the Hwy 84 corridor.
Warmer than normal, dry conditions will last through Wednesday.
553 PM CST Tue Nov 14 2023 (Tonight) Dense high clouds remain in place across the region this afternoon as an area of low pressure passes well to our south along the MS/AL/FL Gulf Coast. This evening and overnight, the slow-moving mid/upper level trough will begin to amplify as it pivots into the western Florida Panhandle. The dense cloud cover will limit our cooling potential, with lows dropping into the low to mid 50s in most locations.
Highs will range from the lower 70s north to mid 60s south. The wedge of high pressure will enhance the pressure gradient in combination with the approaching low and this will also cause breezy conditions to develop tonight and tomorrow.
High pressure will shift east with the next system set to arrive Wednesday night with an initial rain/snow mix changing to snow. At this time, there appears to be a 50 to 80 percent chance for measurable snow of a tenth of an inch over the Little Rockies and north of the Missouri River to the Canadian border, especially the higher elevations near Opheim.
Afternoon GOES vapor imagery depicts upper level ridge across the Great Lakes and Ohio Valley regions, while a stout mid-level short wave trough was evident across the Canadian Prairies.
