545 AM CST Thu Jan 4 2024 A weak cold front will continue to push through the region today. Widespread rain is expected on Friday as a low pressure system moves across the region.
A few locations across central and northeastern Alabama have dropped to below 30 degrees along with the fog, so we have gone ahead an issued a Freezing Fog Advisory through 8 AM. Areas in the north may clear up before then but there still could be some slick spots along bridges. This high pressure will short lived as a progressive pattern begins to take shape.
Closed upper level low continues to spin over northwest Arizona early this morning with some very light, lingering shower activity under its cyclonic circulation. Any remaining shower activity will cease by late this morning as drier and much more stable air continues to overspread the region as the closed low pressure moves into New Mexico. GEFS/EC/GEPS means continue to inch the low center towards the 4 corners which solidly puts the Great Basin underneath a stout northerly jet.
As a result of clear skies, temperatures are running a few degrees cooler now than at this same time yesterday. Expect morning lows today to be in the low 40s for the East and South Bay, with more interior locations seeing slightly colder temperatures in the mid to upper 30s. Friday morning lows to be a few degrees warmer than today thanks to increased cloud cover, with mid 40s in the Bay regions, and low 40s for more interior portions. Highs will be in the upper 50s for valleys and bays, and the low 50s for higher elevations both today and Friday.
628 AM EST Thu Jan 4 2024 A cold front will push across the region this morning, producing scattered snow showers possibly snow squalls across central NY. High pressure builds in behind the front tonight, but some light lake effect snow showers will linger into Friday.
640 AM EST Thu Jan 4 2024 Aviation Lingering north flow lake effect showers will come to an end this morning, then surface ridging moves in place today and Friday. Afternoon temps should peak just below freezing in the upper 20s to low 30s. The center of the high passes to our east this evening and winds gradually shift southwesterly. - Risk for light snow over the weekend Models continue to show mid to upper level height falls as a trough tracks eastward through the Great Lakes Region.
409 AM EST Thu Jan 4 2024 A cold front will push across the region this morning, producing scattered snow showers possibly snow squalls across central NY. High pressure builds in behind the front tonight, but some light lake effect snow showers will linger into Friday.
710 AM EST Thu Jan 4 2024 The low pressure area is tracking over the state this morning, with the cold front trailing behind it. Winds will be shifting from the S/SW to the N/NW by morning as the low lifts out and the cold front pushes south of the area. Some cooler and drier air will move in as high pressure builds today and tonight.
943 AM EST Thu Jan 4 2024 High pressure will build southeast into the Great Lakes and Ohio Valley today into tonight. The high will move east of the area on Friday.
* Low clouds and freezing fog, some dense, mainly this morning.
A weak cold front will continue to push through the region today. Widespread rain is expected on Friday as a low pressure system moves across the region.
Colder the next two mornings, including freezing temperatures around Tucson metro.
632 AM CST Thu Jan 4 2024 Canceling portions of the Freezing Fog advisory for this morning. Areas around Lawton and Duncan, down toward Ardmore and Thackerville may continue to see some patchy fog in low lying spots, but widespread freezing fog no longer expected. North of the Red River, temperatures in areas are expected to drop below freezing and a Freezing Fog Advisory has been issued, while south of the Red River, a Dense Fog Advisory has been issued. An upper level trough will begin to enter into the region Thursday afternoon, with the expansive cloud cover over New Mexico/Colorado shifting eastward into the region this morning and into the afternoon.
638 AM EST Thu Jan 4 2024 Areas of drizzle, freezing drizzle and snow showers will diminish early this morning.
358 AM MST Thu Jan 4 2024 MORNING DISCUSSION: Patchy freezing fog will continue for much of northeastern Montana through the late morning. The main change with this update is accumulation amounts have decreased dramatically with most areas west of a line from Glasgow to Jordan seeing barely any accumulation except for the higher elevations of the Little Rockies.
943 AM EST Thu Jan 4 2024 Dry and cool high pressure will return today through Friday.
407 AM EST Thu Jan 4 2024 The low pressure area is tracking over the state this morning, with the cold front trailing behind it. Winds will be shifting from the S/SW to the N/NW by morning as the low lifts out and the cold front pushes south of the area. Some cooler and drier air will move in as high pressure builds today and tonight.
624 AM EST Thu Jan 4 2024 High pressure will build southeast into the Great Lakes and Ohio Valley today into tonight. The high will move east of the area on Friday.
616 AM CST Thu Jan 4 2024 (Today through Friday) Early this morning, a dry cold front was moving through the Mid State with a trailing blanket of stratocumulus clouds. These clouds will stay over the area most of the morning, then skies should clear out early this afternoon as dry high pressure builds over the area.
629 AM EST Thu Jan 4 2024 Dry and cool high pressure will return today through Fri. A modest low pressure system will bring showers Sat, followed by dry high pressure Sun into Mon. The axis of showers is about halfway through the CWA as of 2am EST and activity is expected to be all offshore by about 6am EST as low pressure moves further out to sea. Otherwise, dry weather expected with highs about 5 deg below normal in the lower-mid 50s.
(This evening through Friday) Afternoon water vapor imagery shows the upper level low spinning over New Mexico. Ahead of the upper low precipitation has developed from the Trans Pecos and Permian Basin up into the Panhandle, where snow is being reported. The upper low will move eastward across the Panhandle overnight and into northern Oklahoma Friday morning. The upper low will lift off to the northeast of the region on Friday.
129 PM CST Thu Jan 4 2024 * Low clouds and freezing fog, some dense, mainly this morning.
1014 AM CST Thu Jan 4 2024 - Very limited (<15%) chance of light freezing drizzle over SE WI early Friday. CMiller Issued 243 AM CST Thu Jan 4 2024 Today through Friday: Today looks to be another day of stubborn cloud cover, with a thin layer of stratus trapped under high pressure moving through the region. As the high moves east of the region tonight, southwest flow and associated warm advection will develop, with additional low clouds pushing in from the southwest. We will again have a risk for patchy freezing drizzle very late tonight into early Friday, with the highest chances over southeastern Wisconsin, where low level warm/moist advection will be maximized. Otherwise, cool and cloudy conditions are expected once again for Friday, with highs in the low to mid 30s.
(This evening through Friday) Cloud cover will continue to move in ahead of an advancing mid- level trough. Surface temperatures will initially be too warm for winter precipitation, but as the trough moves over the area, dynamic cooling in the mid levels could be realized at this surface by Friday morning. Temperatures will be near freezing, but higher precipitation rates will allow for snowfall.
With low temperatures lingering in the lower 30s across portions of southwest Arkansas and the higher terrain of McCurtain county, there is some question as to whether any of this precipitation could transition to a rain/snow mix. For this forecast package, I maintained a wintry mix wording but feel that ongoing liquid precip accumulation values of up to a quarter of an inch along with higher rain rates and temperatures hovering at or slightly above freezing will likely mitigate any winter weather impacts. Otherwise, mainly dry conditions expected on Friday night as high pressure rebuilds across the region with temperatures forecast to fall into the low to mid 30s.
1231 PM EST Thu Jan 4 2024 High pressure will build southeast into the Great Lakes and Ohio Valley today into tonight. The high will move east of the area on Friday.
Will leave the High Wind Warning for the Guadalupe and Delaware Mountains unchanged. Upper level low will move across the area today and tonight moving the low clouds and light precipitation out of the area to the east by around midnight local time. Windy conditions across the higher elevations subside by early tomorrow morning. Drier air in combination with clearer skies allow Friday morning lows to dip closer to normal with near freezing temperatures over the Permian Basin and 20s across southeast New Mexico and the Marfa Plateau.
1130 AM CST Thu Jan 4 2024 - Overcast skies, fog and freezing fog will likely linger through much of the day. - Accretion of ice from fog along with the potential for some light freezing drizzle could make for slick surfaces today. As a result, the winter weather advisory now goes into effect at 9AM, mainly for the freezing drizzle potential impacting area roadways. - Any freezing drizzle should transition to light snow by late this afternoon or evening, with around an inch of total snowfall accumulation in the most favored locations south of Highway 6, although most area will likely only receive a dusting to a few tenths of snowfall accumulation with this first system.
313 PM EST Thu Jan 4 2024 Gradually decreasing clouds tonight and somewhat warmer on Friday.
Cloud coverage has increased dramatically, so temperatures are still hovering near 70 degrees into the lower 70s. Dew points will briefly drop back into the lower 60s overnight, but a major cooldown is not expected. From synopsis, breezes will shift rapidly around the compass during the next five days, as a series of low pressure systems slides east through the Gulf of Mexico.
1143 AM CST Thu Jan 4 2024 * Low clouds and freezing fog, some dense, mainly this morning.
109 PM MST Thu Jan 4 2024 Main forecast challenge this afternoon is the low cloud/fog deck that is over the northern and eastern zones. Better lift and moisture is expected to the north of the CWA but there is a slight chance of snow with the upper trough moving through.
1112 AM CST Thu Jan 4 2024 Another cold start to the day with most observation sites reporting temps just above freezing. (Today through Friday) Early this morning, a dry cold front was moving through the Mid State with a trailing blanket of stratocumulus clouds. These clouds will stay over the area most of the morning, then skies should clear out early this afternoon as dry high pressure builds over the area.
GOES Visible satellite is highlighting a rope cloud along the leading edge of a weak front that is moving through the Lower Keys.
214 PM CST Thu Jan 4 2024 * Low clouds and freezing fog, some dense, mainly this morning.
Dense fog is lingering in the Lower Treasure Valley and Upper Magic Valley this morning, so the advisory has been extended through 11am MST.
Lingering north flow lake effect showers will come to an end this morning, then surface ridging moves in place today and Friday. Afternoon temps should peak just below freezing in the upper 20s to low 30s. The center of the high passes to our east this evening and winds gradually shift southwesterly. - Risk for light snow over the weekend Models continue to show mid to upper level height falls as a trough tracks eastward through the Great Lakes Region.
1132 AM CST Thu Jan 4 2024 - Fog and freezing fog will be possible this morning, leading to possible slick conditions especially on elevated surfaces such as bridges and overpasses.
(This afternoon through Friday Night) Temperatures have warmed nicely across the region this afternoon with most observation sites sitting in the low 40s.
1137 AM CST Thu Jan 4 2024 A weak cold front will continue to push through the region today. Widespread rain is expected on Friday as a low pressure system moves across the region.
1122 AM CST Thu Jan 4 2024 Canceling portions of the Freezing Fog advisory for this morning. Areas around Lawton and Duncan, down toward Ardmore and Thackerville may continue to see some patchy fog in low lying spots, but widespread freezing fog no longer expected. North of the Red River, temperatures in areas are expected to drop below freezing and a Freezing Fog Advisory has been issued, while south of the Red River, a Dense Fog Advisory has been issued. An upper level trough will begin to enter into the region Thursday afternoon, with the expansive cloud cover over New Mexico/Colorado shifting eastward into the region this morning and into the afternoon.
Our first of three cold fronts pushed through early this morning leaving behind a thick layer of low clouds. The clear skies and the cooler airmass overhead will give us one cool night in the 40's and low 50's before winds start to shift southerly ahead of our next frontal system.
/16 (Now through Friday night) Weak upper ridging over the Southeast will give way to an upper trough moving from over the Plains and passing north of the forecast area Friday through Friday night. The trough takes a negative tilt as it passes, with a strong upper jet streak bringing good upper divergence to the Southeast as it passes. This low passes over our piece of the Gulf coast late Friday into Friday night. A warm front organizes over the Gulf ahead of the approaching low and moves north to the coast during the day Friday.
1030 AM CST Thu Jan 4 2024 Another cold start to the day with most observation sites reporting temps just above freezing. (Today through Friday) Early this morning, a dry cold front was moving through the Mid State with a trailing blanket of stratocumulus clouds. These clouds will stay over the area most of the morning, then skies should clear out early this afternoon as dry high pressure builds over the area.
1214 PM EST Thu Jan 4 2024 Dry and cool high pressure will continue today through Friday.
347 PM EST Thu Jan 4 2024 High pressure will slowly cross southeast through Ohio tonight.
234 PM CST Thu Jan 4 2024 - Occasional light snow chances (20-60%) this weekend with the highest odds of light accumulations (at least 1") across north-central WI.
1243 PM EST Thu Jan 4 2024 Areas of drizzle, freezing drizzle and snow showers will diminish early this morning.
Unfortunately, expect the stratus layer to stay in place overnight as an upper-level ridge continues to move through the region. Shifting gears to precipitation, while subsidence from the ridge should keep any significant precipitation chances at bay tonight; increasing moisture in the lower levels could lead to some periods of freezing drizzle late tonight. Otherwise, expect another cool night as overnight lows only decrease into the low to upper 20s.
617 PM CST Thu Jan 4 2024 - Areas of fog, freezing drizzle and light snow continue tonight through Friday night.
Latest upper analysis shows a northern stream ridge crossing the northern plains this afternoon with an upper low in the southern stream over New Mexico. A surface cold front will drop into far northwestern South Dakota later tonight, bringing low stratus and possibly additional fog to that area. This will push the cold front farther southward into the forecast area bringing a chance of snow.
Upper-level clouds will spill over the region ahead of a digging trough in the southern Mississippi River Valley, and help keep overnight lows in the mid to upper 20s. What appeared to be a low threat for freezing drizzle overnight thankfully appears to have gone away completely thanks to the sunshine this afternoon (e. Tomorrow will be marked by thickening upper-level clouds as the aforementioned upper-level trough continues digging into the southern Mississippi River Valley.
548 PM CST Thu Jan 4 2024 (This evening through Friday) Cloud cover will continue to move in ahead of an advancing mid- level trough. Surface temperatures will initially be too warm for winter precipitation, but as the trough moves over the area, dynamic cooling in the mid levels could be realized at this surface by Friday morning. Temperatures will be near freezing, but higher precipitation rates will allow for snowfall.
617 PM EST Thu Jan 4 2024 High pressure will slowly cross southeast through Ohio tonight.
537 PM EST Thu Jan 4 2024 Gradually decreasing clouds tonight and somewhat warmer on Friday.
550 PM CST Thu Jan 4 2024 - Occasional light snow chances (20-60%) this weekend with the highest odds of light accumulations (at least 1") across north-central WI.
Have updated the forecast to cancel the High Wind Warning for the Guadalupe and Delaware Mountains. Wind speeds there have decreased below Warning criteria, and given the location and trajectory of the upper level low and trough moving across the region, winds will continue their downward trend through this evening. Will leave the High Wind Warning for the Guadalupe and Delaware Mountains unchanged. Upper level low will move across the area today and tonight moving the low clouds and light precipitation out of the area to the east by around midnight local time. Windy conditions across the higher elevations subside by early tomorrow morning. Drier air in combination with clearer skies allow Friday morning lows to dip closer to normal with near freezing temperatures over the Permian Basin and 20s across southeast New Mexico and the Marfa Plateau.
Three troughs are involved, one that entered this morning, another Friday morning, and a third starting Sat afternoon and continuing into Sun morning. Lower elevations to approach the freezing mark, lowering snow ratios, so snow appears to reach Advisory criteria only above 6000ft elevation. Not that lower elevations will receive nothing; even Pocatello benches will get multiple inches and the lowest elevations receiving right around 2 inches for tonight through Fri afternoon. Moderate to strong wind is only expected on the ridges south of Burley in Cassia county, the Albion and Cotterel ranges.
532 PM CST Thu Jan 4 2024 (This evening through Friday) Afternoon water vapor imagery shows the upper level low spinning over New Mexico. Ahead of the upper low precipitation has developed from the Trans Pecos and Permian Basin up into the Panhandle, where snow is being reported. The upper low will move eastward across the Panhandle overnight and into northern Oklahoma Friday morning. The upper low will lift off to the northeast of the region on Friday.
527 PM CST Thu Jan 4 2024 (This afternoon through Friday Night) Temperatures have warmed nicely across the region this afternoon with most observation sites sitting in the low 40s.
From synopsis, breezes will shift rapidly around the compass during the next five days, as a series of low pressure systems and associated fronts slide east through the Gulf of Mexico.
1221 AM EST Fri Jan 5 2024 Gradually decreasing clouds tonight and somewhat warmer on Friday.
1058 PM CST Thu Jan 4 2024 - Overnight some light freezing drizzle is possible across western and central Minnesota leading in some icy roads for Friday morning.
1251 AM EST Fri Jan 5 2024 High pressure will provide dry weather today. Low pressure advancing from the southwest is forecast to bring accumulating snow on Saturday.
954 PM CST Thu Jan 4 2024 - Overnight some light freezing drizzle is possible across western and central Minnesota leading in some icy roads for Friday morning.

221 AM CST Fri Jan 5 2024 - Patchy freezing drizzle possible through the morning hours today.
Water vapor imagery currently shows upper low situated over the TX Panhandle and moving into western OK with a large area of diffluence across western and central KS. Also keeping with the thinking that precip type will remain either snow or rain, with temps in the lowest 500ft or so being the determining factor. Models remain consistent in lifting a powerful upper trough out of the Desert Southwest and out into the Southern Plains on Mon. However, there still remains some small differences in track of the upper low which will have a significant impact on amount and location of wintry precip.
1106 PM CST Thu Jan 4 2024 (This evening through Friday) Cloud cover will continue to move in ahead of an advancing mid- level trough. Surface temperatures will initially be too warm for winter precipitation, but as the trough moves over the area, dynamic cooling in the mid levels could be realized at this surface by Friday morning. Temperatures will be near freezing, but higher precipitation rates will allow for snowfall.
1047 PM CST Thu Jan 4 2024 - Occasional light snow chances (20-60%) this weekend with the highest odds of light accumulations (at least 1") across north-central WI.
248 AM CST Fri Jan 5 2024 - Freezing drizzle in western/central Minnesota this morning could lead to hazardous travel early.
1244 AM EST Fri Jan 5 2024 High pressure will provide dry weather today. Low pressure advancing from the southwest is forecast to bring accumulating snow on Saturday.
356 AM EST Fri Jan 5 2024 High pressure builds in today and brings an end to lake effect snow showers.
We are still on the way to morning lows in the 40s for much of the area, with locations east of Interstate 95 bottoming out in the low to mid 50s. It would not be a surprise to see some interior portions of Lake and Volusia counties fall into the low 40s for a brief time Friday morning. Clouds increase ahead of another cold front after 00z Sat.
High pressure that has controlled our wx the past 24 hours will slide east of our area today as a trough moves from the plains toward the Tennessee Valley. A few showers with the advancing trough may reach our far western counties late in the afternoon. A swath of rain will cross the Mid State tonight as the trough from the plains zips overhead. There will be no wintry impacts or accumulations as deep south southwest flow quickly warms and saturates the lowest 5kft of the atmospheric column.
Also on satellite imagery/RAP analysis was a closed low spinning over the Texas and Oklahoma panhandles. Early morning surface analysis had a 1010mb low beneath the closed low and another 1010mb low along the far southeast Texas coast. The closed low will track northeast through the period, opening up and weakening as it does so. Cloud cover and rainfall will hold temperatures a few degrees cooler than normal today and then help hold temperatures a couple degrees warmer than normal tonight.
523 AM CST Fri Jan 5 2024 - Freezing drizzle in western/central Minnesota this morning could lead to hazardous travel early.
(Today and tonight) Upper low will lift northeast into the Midwest states later today, with a drier airmass filtering into the region. Look for highs this afternoon in the mid and upper 50s, with a few readings in the lower 60s over far southeast counties.
426 AM EST Fri Jan 5 2024 High pressure ridging across the area from the north shifts east today as the next frontal system approaches from the northern Gulf region.
224 AM MST Fri Jan 5 2024 Dense freezing fog has overspread most areas from Malta, Circle, Terry and points north and east overnight. Low level moisture will remain trapped under a low level inversion this morning until a cold front moves in and mixes the atmosphere. Better mixing today will also allow for somewhat warmer temperatures despite cold air advection aloft.
408 AM EST Fri Jan 5 2024 High pressure builds in today and brings an end to lake effect snow showers.
