920 PM EST Sun Jan 9 2022 A cold front will cross the area this evening.
/NEW/ /Through Monday Night/ In the wake of our latest cold front that swept east- southeastward across the region earlier today, noticeably cooler air and brisk north winds resulted in a chilly Sunday across North and Central Texas. Cloud cover is likely to inhibit more robust overnight cooling tonight, but temperatures should still manage to fall below freezing in many areas across North and western Central Texas. Widespread freezing temperatures expected Monday night across North and Central Texas as excellent radiational cooling conditions come together.
Hennig (This afternoon through Monday night) It is a much cooler day today across the region in the wake of a cold front that has now progressed through the Rio Grande Valley. Gusty northerly to northeasterly winds that have made it feel much cooler for most of the day will continue to diminish through the remainder of the afternoon and into early evening, with light winds then expected overnight. Despite this, continued cold advection and slowly veering winds will yield a cold night, with lows ranging from the lower 20s north to the 30s and lower 40s through the Rio Grande Valley.
921 PM EST Sun Jan 9 2022 High pressure will build into the area bringing a return to below normal temperatures for the next couple of days. Once the high moves east, southerly flow will allow temperatures to rise above normal for mid to late week. The high will build into the forecast area during the period.
908 PM EST Sun Jan 9 2022 An Arctic airmass moving in will bring temperatures back below freezing.
Looking at the synoptic setup into Monday, the ridge of high pressure currently over the area will shift east into the central Great Basin. Meanwhile, a trough of low pressure approaching the west coast will split in two. The greatest uncertainty for Monday morning fog development in the valley will be cloud cover associated with the aforementioned trough.
Cold front extends generally along the Natchez Trace Corridor this afternoon, as it continues to move southeast across the area. High pressure ridging will build in over the area on Monday, with clear skies and highs ranging from the mid 40s to mid 50s. Initially, the region will remain under northwest flow/broad troughing aloft and high pressure at the surface following the recent frontal passage. Overnight lows will initially be near freezing and daytime highs in the 50s. By mid-week, the high pressure will move east and southerly flow will resume once again. Following this upper trough passage, upper ridging will move into the region for the end of the week.
High pressure remains in control of the region through much of the upcoming week, allowing dry conditions to prevail.
/issued 216 PM CST Sun Jan 9 2022/ 19Z Surface analysis places an arctic cold front from the Eastern Great Lakes region back through the Ohio Valley, Middle Tennessee, North Mississippi, and into Louisiana. Rain has diminished across the Mid-South this afternoon as cold high pressure is building behind the front. The aforementioned cold front will continue to push away from the region tonight as cold high pressure continues to filter into the Lower Mississippi Valley.
Rain is gradually ending from northwest to southeast behind a cold front this afternoon. One thing we'll be keeping a close eye on is the potential for a flash freeze as temperatures drop below freezing. We'll gradually warm above the freezing mark by the afternoon, but not by much. Highs will only top out in the low to mid 30s across most of southern Indiana and central Kentucky, and upper 30s near the Tennessee border. At the surface, an expansive high pressure center keeps the weather tranquil while the Arctic air mass slowly modifies.
217 PM MST Sun Jan 9 2022 Broad upper trough encompasses the eastern 2/3 of the CONUS, with a high amplitude upper ridge parked over the western 1/3.
--Cold continues Monday, warmer middle of the week. Accumulations, if any at all, would be very light as forecast soundings suggest saturation deficits in the low levels that would have to be overcome for any snow to make it to the ground. Monday will remain on the colder side with northwest flow and CAA continuing in the mid levels as the mid level trough continues to push eastward over the Ohio Valley. At the surface, high pressure conditions return clearing out any cloud cover from overnight and bringing another day of sunshine despite high temperatures in the single digits northeast to mid 20s southwest.
649 PM EST Sun Jan 9 2022 Some MVFR/IFR cigs/vsbys may impact the terminals between 09-13Z as increasing moisture ahead of a cold front supports lower cigs along with some patchy fog development, otherwise VFR will prevail. Some isolated SHRA will be possible through 02Z tonight especially at the coastal terminals where VCSH has been advertised, with additional SHRA and MVFR cigs possible between 14-21Z in association with the cold front moving south through the region. /issued 308 PM EST Sun Jan 9 2022/ Upper level trough and associated low pressure system will move across the eastern U.
There is about a 20 degree drop in temperatures behind the front with tomorrow morning lows into the lower 40s.
A warming trend will commence this week as a large ridge builds across the West.
We remain under northwest flow in the wake of yesterday's frontal/trough passage. High pressure will continue to build across the Intermountain West through the next 24 hours or so. Some energy left behind by the recent trough will attempt to form a Rex Block just to the south of us. But, it does look to clean the low to the south of us out as it moves through. Temperatures in our low valleys look to decrease tomorrow versus today according to latest model blends and this makes sense given recent inversions with high pressure aloft.
High clouds will spread in front of the trough, limiting any frost formation to cold interior valleys overnight. While a narrow wedge of moisture will be pulled north by the trough, instability looks truly pitiful. The trough will setup a decent pressure gradient along the coast Monday morning. NBM has a 0% chance of advisory level winds, even on ridges.
526 PM CST Sun Jan 9 2022 High pressure is building into the Mid Mississippi River Valley from the Northern Plains today. Light and variable tonight ahead of a weak low along with a clear sky will produce excellent radiational cooling conditions with lows dipping into the low to mid teens. The low will briefly turn the wind back to the south and southwest during the predawn hours of Monday morning. The low will move from southwest Iowa across northeast Missouri Monday Morning and into the Ohio Valley by Monday afternoon. The weak warm advection to the south of the low track will allow temperatures to warm into mid 30s to low 40s along and south of the I-70 corridor in Missouri and the I-64 corridor in Illinois.
Otherwise, a low pressure system will bring an increased chance of rain and mountain snow during the latter half of the work week with slightly cooler temperatures. This will direct cooler air to areas east of Tucson tomorrow afternoon while Tucson westward will benefit from some downsloping to temper the cooling.
742 PM EST Sun Jan 9 2022 An Arctic airmass moving in will bring temperatures back below freezing.
For Monday, cloud cover increases along a baroclinic zone, located to our west in association with an approaching ridge. Southerly flow develops Monday afternoon with strong WAA overnight in response to the H5 ridge as it continues eastward.
452 PM MST Sun Jan 9 2022 00Z TAF CYCLE Strong high pressure will build in from the west over northern NM while a weak and dry upper-level low develops over southwest NM. A cold front has pushed across the area and will bring colder temperatures through tonight.
408 PM MST Sun Jan 9 2022 Dry weather on tap for the start of the work week as a ridge of high pressure builds to our west and northwest flow aloft prevails. A lee trough over eastern Wyoming strengthens the pressure gradient late Monday morning and afternoon in response to the temperature difference across the state. Snow-covered basins east of the Divide will be around seasonal averages, while the western valleys and basins remain below freezing.
603 PM MST Sun Jan 9 2022 0600PM UPDATE: Changes to the forecast were minor with the main focus being on the low clouds drifting across the far northeast GOES Nighttime fog product. A warming trend will commence this week as a large ridge builds across the West.
538 PM EST Sun Jan 9 2022 An Arctic airmass moving in will bring temperatures back below freezing.
/Issued 1115 AM CST Sun Jan 9 2022/ /This Afternoon through Monday Night/ A strong cold front continues to push through North Texas this morning and is located from near Paris to Corsicana to Temple. Brisk northwest winds and much cooler air will filter in behind the front. High pressure will build into the region tonight and winds should diminish some. High pressure will slide eastward Monday night allowing light southerly winds to resume. Overnight lows Monday night will be near freezing in most locations.
Cold front has moved east of Middle Tennessee, with only some spotty showers still affecting the Cumberland Plateau. A brisk north wind will push colder, drier air into Middle Tennessee during the next several hours, but will start to diminish after 06Z as high pressure builds into the mid state.
Dry and seasonable for today through the mid portions of the upcoming week as high pressure dominates the weather. Upper ridge axis overhead today. Have kept patchy freezing fog for low- lying areas in the forecast for the overnight and tomorrow morning, although confidence is low. Tomorrow the ridge will flatten slightly as an upper trough pushes across the US Northwest, clipping northern NV.
114 PM PST Sun Jan 9 2022 Fair and dry weather will prevail through the middle of the week as offshore flow takes hold across the region thanks to a cutoff low to the south and high pressure expected to keep us company here in the southwestern part of the country. These features will bring some warmer weather to areas west of the mountains, along with gusty Santa Ana winds across the coastal slopes of the mountains into some inland valleys.
Winds will weaken overnight in the wake of today's cold front that moved across the state.
639 PM EST Sun Jan 9 2022 High pressure will build into the area bringing a return to below normal temperatures for the next couple of days.
