400 PM EST Sat Jan 29 2022 Arctic high pressure will build across the Southeast through tonight, ahead of a moisture-starved clipper low that will cross the central Appalachians and southern Mid Atlantic Sunday and Sunday night. At the surface, high pressure will remain anchored across FL on Sunday, and a fast-moving clipper low will dive from the Midwest early Sunday to across NC/VA by late Sunday night. Dry air in the lower levels will remain across central NC early in the day, with dewpoint temperatures still in the single digits. A lack of sufficient forcing and moisture in the lower- levels will yield dry weather throughout the period as the two systems move by central NC. Highs will increase around 10 degrees compared to Saturday, ranging from the low to mid-40s.
Low clouds continue to cover much of southeast Oregon and part of the Lower Treasure Valley of Idaho, and we believe it will erode further today. High pressure will maintain the dry and stable conditions through the weekend for a continued strong surface-based inversion.
In fact, dew points are some of the lowest we've seen and the same goes for Relative Humidity values. High pressure has begun to rule so that is also a factor is helping this dry airmass stick around. Temperatures will once again be on the cooler side for most locations.
Some mid and high level clouds are expected to spread across the region on Sunday which may keep highs a tad cooler than today.
220 PM CST Sat Jan 29 2022 Now that a surface warm front has moved across the area, a backdoor cold front is close on its heels. Even with the cloud cover, we will be a bit chillier than last night behind the weak cold front. The pattern almost repeats itself on Sunday, with a warm front moving through from west to east during the first part of the day, followed by a weak cold front later in the day. Highs will be similar as today, ranging from the lower 20s across the Turtle Mountains to the mid 40s southwest. Quiet weather continues Sunday night, with lows a bit warmer, in the teens to upper 20s for most.
High pressure will move through the northern Gulf. ample radiational cooling will allow low temperatures to be in the low 20's in the east and upper 20's in the west. warmer air will begin advecting into the state with temperatures several degrees warmer in the mid 50's to lower 60's.
(Through tonight ) Expanding low level thermal ridge along with downslope wind component resulting in a robust warmup this afternoon, more than a 50 degree diurnal rise in a few spots across eastern OK in fact.
349 PM EST Sat Jan 29 2022 NW flow aloft is well established from the Midwest into the Ohio Valley as the deep closed low heads up into New England. Temps will only run slightly below seasonal normals on Sunday as a sfc trof drags through behind the Clipper, with a wind shift as its only sensible wx impact.
1244 PM EST Sat Jan 29 2022 Aviation - A Few Light Snow Showers Tonight - Clouds will gradually increase today out ahead of a weak low pressure system that will bring some light snow showers mainly across our northern fcst area tonight where deeper moisture and some lift will develop.
The latest data indicates rapid eastward expansion of the low level thermal ridge during the day today across the region as downslope flow kicks into high gear. Given the low sun angle this time of year, we won't realize max potential, but it will be close.
1009 AM EST Sat Jan 29 2022 High pressure builds in today ushering in drier weather after scattered morning snow showers for some.
1028 AM CST Sat Jan 29 2022 Skies are clear with a light variable wind as high pressure is settling over the region today. Later today and into tonight high pressure will begin scooting east and anticyclonic flow around it will bring slightly warmer temperatures back into southeast TX and southwest LA. This will bring light winds and dry conditions in the low levels.
919 AM CST Sat Jan 29 2022 Northwesterly flow aloft will persist throughout the day as a mid- level trough swings offshore. Higher elevations will stay in the low 30s with localized areas not reaching above freezing. This westerly low level flow should bring somewhat warmer and more moist air back into the region this evening. However, lows will still drop into the lower to mid 20s in most locations.
High pressure overhead will keep lots of sun over most of the area for the rest of the day. A minor short wave trough aloft will bring in some clouds to the west late. The short wave trough moving across the area this period night will mainly make clouds.
1138 AM CST Sat Jan 29 2022 High pressure is in control over the area.
High pressure remains in firm control of the weather today. Temperatures dropped into the low to mid 20s again here in the Rogue Valley this morning (even in Ashland where SE winds kept the temperature a bit higher there yesterday morning -- those winds have since relaxed). With the high in control, expect a rapid warm up in most areas with a sunny, milder afternoon and highs in the 50s to low 60s west of the Cascades and in the upper 40s to low 50s over the East Side.
110 PM EST Sat Jan 29 2022 High pressure will continue dry and cold weather tonight. Scattered snow showers are possible Sunday with fast-moving low pressure. Wind will be fairly light overall, save for speeds of up to 10 knots on the ridges, and clouds will begin to increase after midnight as warm advection commences behind the ridge axis. However, the higher elevations stand a decent chance of seeing some apparent temperatures of -10 to -15 overnight/Sunday morning, with the bit of added wind and clouds arriving a little later.
/issued 1028 AM CST Sat Jan 29 2022/ Arctic high pressure has settled over the Mid-South this morning. The high will begin shifting east this afternoon allowing for winds to turn around to the south. Temperatures are in the low 20s across most of the area. Wind chill may dip to around 10 degrees across portions of west TN with most of the Midsouth in the low to mid teens.
Most of the region is already in the low to mid 40s, and a few locations will reach upper 40s this afternoon. Will still be cold tonight as clear skies and light winds are expected as high pressure gradually moves east of the area. Return flow begins to set up on Sunday, with daytime highs rebounding into the low to mid 60s across most of the area. Winds remain a bit elevated this afternoon, between 10-15 knots with higher gusts possible, but will be subsiding tonight (becoming light and variable over most inland areas) as high pressure tracks east across the area.
305 PM EST Sat Jan 29 2022 Strong low pressure center is currently off the northern Mid Atlantic coast. High pressure is currently centered across the Lower Mississippi River Valley. The high center will move east across the northern GOMEX through Sunday. With a high pressure ridge moving overhead, winds should be 5 mph or less across most locales.
High temperatures today are struggling to get to near freezing with most of the area reaching into the upper 20s to around 30 except the high elevations of east Tennessee and southwest Virginia. The central and southern valley areas that did not get much snow should reach the lower to possibly mid 30s by late afternoon.
1027 AM MST Sat Jan 29 2022 The weekend will remain dry as ridging persists over the region. The well-advertised pattern change comes barreling through early in the week, as the H5 ridge finally breaks down. The initial push will be a system sweeping across Montana, dragging the first cold front into northern WY.
1232 PM PST Sat Jan 29 2022 A blocking area of high pressure off the West Coast will continue the quiet and dry conditions through the coming week.
Northwesterly flow aloft will persist throughout the day as a mid- level trough swings offshore. Higher elevations will stay in the low 30s with localized areas not reaching above freezing. This westerly low level flow should bring somewhat warmer and more moist air back into the region this evening. However, lows will still drop into the lower to mid 20s in most locations.
Since then temperatures have fallen into the upper 50s to lower 60s for the middle and upper Keys, while falling into the lower 50s in the upper Keys. Therefore, expecting some sun over the next hour or so with more clouds moving in for the lower Keys. Temperatures will fall into the lower 40s in the upper Keys.
For tonight, the high pressure center will move over the area, and winds will likely go calm. Thus, the official forecast low temperatures are on the lower end of the guidance with lows in the low to mid 20s across most inland areas and upper 20s to lower 30s along the panhandle coast.
SHORT TERM (Tonight through Sunday Night): Weak mid level high pressure continues to build into early Sunday before a 500mb trough dives southeast across Texas Sunday night.
1120 AM CST Sat Jan 29 2022 Upper level ridging over the western U.
1005 AM MST Sat Jan 29 2022 Current surface map place warm front across the eastern Dakotas with mild temperatures across the high plains. Upper Ridge over the Rockies/Northern Plains flattens this weekend, with warm, dry, breezy conditions.
223 PM CST Sat Jan 29 2022 A mid/upper ridge was centered across the Central Great Basin area while a vigorous storm system was impacting the Mid-Atlantic and Northeast.
SKC early on Sunday will see increasing mid and high clouds ahead of a few showers to start the work week with a weakening upper low traversing the Gulf coast. Even with clear skies, afternoon highs will only get up into the low-50s to the east, whereas our western zones can expect to see highs in the low-60s.
1028 AM CST Sat Jan 29 2022 Arctic high pressure has settled over the Mid-South this morning. The high will begin shifting east this afternoon allowing for winds to turn around to the south. Temperatures are in the low 20s across most of the area. Wind chill may dip to around 10 degrees across portions of west TN with most of the Midsouth in the low to mid teens.
1027 AM MST Sat Jan 29 2022 Upper level high pressure builds into Colorado today, bringing clear skies and warmer temps to most locations. Still looking at fairly strong inversions this morning over interior valleys, and with limited mixing under the high, max temps will struggle, and cut back numbers several degf from NBM at usual cold spots (i.
221 PM CST Sat Jan 29 2022 Short wave ridging will move overhead this evening through Sunday morning in advance of an upper low moving east across the southwestern US. As the upper low approaches the area during the day on Sunday, weak surface lee troughing will develop in response.
The upper level trough axis has shifted over the area and much colder air is filling in. Looking at satellite imagery, most of the snow that fell overnight has melted now that temperatures have increased a few degrees above freezing. The trough has ushered in very dry air with dewpoints in the single digits; some of the lowest this season. High pressure will continue to build into the Southeast. High pressure will continue to dominate the weather pattern over the Southeast U.
Lee trough from central MT into southeast WY. Tonight through Sunday night, upper ridge over the western CONUS will flatten as thermal ridge remains anchored over the CWA assisted by low level downslope flow.
The cold front will move through the region overnight tonight, with very little impact on the sensible weather other than a wind shift to the northwest. Temperatures tomorrow will be slightly cooler than today, but largely near normal under a mostly clear sky.
(This evening through Sunday) With some minor ridging in place, mild weather should continue through tomorrow. Lows tonight will be in the 20s to lower 30s (clear skies and light winds will allow for efficient radiational cooling tonight) followed by highs in the 60s tomorrow afternoon (slightly cooler than today as a cut-off low approaches central Texas).
217 PM CST Sat Jan 29 2022 After the chilly start in the teens this morning, temperatures have warmed quite a bit this afternoon with latest readings in the low to mid 20s on the Plateau and the upper 20s to mid 30s elsewhere. Much warmer conditions are on the way tomorrow with highs around 20 to 30 degrees above what we're seeing today in the mid 40s to low 50s.
350 PM EST Sat Jan 29 2022 Below normal temperatures will continue overnight as Arctic high pressure shifts to the east. Highly amplified mid and upper level flow pattern with deep trof centered over the eastern Great Lakes shifting off to the east this evening. A narrow ridge of surface Arctic high pressure centered over the area to build off to the east. WAA on the back side of the ridge and isentropic lift develops with mid level clouds developing this evening. Temperatures look to trend warmer, ranging from 30 north to 40 south.
752 PM EST Sat Jan 29 2022 A very strong area of low pressure will track toward the Canadian Maritimes tonight as high pressure builds to the south of the local area.
High clouds will clear out this afternoon and tonight with clear skies and warmer temperatures on Sunday.
But as previous discussion stated, just climb the hills and feel the warmth of winter where temperatures are running 10 to 15 degrees warmer. Back to the forecast, dry conditions will prevail through Sunday night with upper level ridging parked overhead. Warming at 700 mbs will help to hold some of the higher elevation mins up, but the valleys will again tumble. This low slides into West Texas Sunday night with our flow becoming a little more pronounced out of the west-northwest as a new system takes aim on the region.
A cold front will move across the area tonight and make a cooler day on Sunday, with highs in the 40s.
Freezing fog will again be possible in these areas. Freezing fog is also possible across portions of west-central Montana and north-central Idaho.
Leaned on the warmer side of guidance once again for the snow free areas of the CWA for highs on Sunday, which puts the western CWA in the low 50s for highs.
A back door cold front looks to push from northeast to central this evening before stalling out later tonight. Now that a surface warm front has moved across the area, a backdoor cold front is close on its heels. Even with the cloud cover, we will be a bit chillier than last night behind the weak cold front. The pattern almost repeats itself on Sunday, with a warm front moving through from west to east during the first part of the day, followed by a weak cold front later in the day. Highs will be similar as today, ranging from the lower 20s across the Turtle Mountains to the mid 40s southwest. Quiet weather continues Sunday night, with lows a bit warmer, in the teens to upper 20s for most.
So with SW flow again tomorrow, expect a warmer day again with high temps edging toward the 70 degree mark.
640 PM MST Sat Jan 29 2022 Upper level ridge will bring us another dry and mild night. Location of surface trof also supports a colder night in our east. The ridge will continue to be the dominate force through the remainder of the weekend. Overnight expecting the winds to keep the temperatures a little warmer, much like last night.
It was not a huge bust, but temperatures did end up a few degrees warmer than forecast under mostly clear skies. Temperatures on Sunday were nudged upward in this forecast package but will probably still end up a few degrees cooler than today as a weak trough passes to our northeast.
A weak upper low will bring a chance for some snow flurries along and south of I-40 late tonight and mainly in the White Mountains on Sunday.
509 PM CST Sat Jan 29 2022 (This evening through Sunday) With some minor ridging in place, mild weather should continue through tomorrow. Lows tonight will be in the 20s to lower 30s (clear skies and light winds will allow for efficient radiational cooling tonight) followed by highs in the 60s tomorrow afternoon (slightly cooler than today as a cut-off low approaches central Texas).
Very similar pattern tonight into tomorrow under a ridging pattern aloft. Still expect the high valleys, particularly Middle Park, to dip well into the negatives with lows likely -20 F or less in a few spots. Sitting near the thermal belt, the foothills will be the warmest, helped too by lingering west winds through the night which should keep lows above freezing in some locations. Sunday will again be quite mild during the day, with temperatures well above normal east of the Front Range (cooler again for areas with greater snow cover). MOS guidance is also relatively consistent in showing slightly warmer temperatures in the plains tomorrow. West winds will remain breezy in the mountains where gusts 45 to 50 mph will be likely for the higher peaks and passes.
As of 9PM temps have reached freezing in parts of northern Lake County and far inland Volusia County, with temps in the mid to upper 30s in the Orlando suburbs, coastal Volusia and Brevard Counties, and southern Osceola to Okeechobee Counties. For the coastal counties lows tonight will settle between 27F-31F, with 5 to 8 hours of freezing temperatures. Wind chills tonight bottom out in the low 20s areawide, except mid to upper 20s in Martin County. The last time Stuart reached freezing was back on December 15, 2010 when the low as 30F, and temps reached 35F back on January 18, 2018.
534 PM CST Sat Jan 29 2022 (Through tonight ) Expanding low level thermal ridge along with downslope wind component resulting in a robust warmup this afternoon, more than a 50 degree diurnal rise in a few spots across eastern OK in fact.
Arctic high pressure will continue to shift east tonight. Light southwesterly winds and warm air advection will allow lows to be warmer with readings expected to be in the upper 20s to mid 30s. A weak cold front will move through the Mid-South on Sunday. Lows Sunday Night may be a tad cooler than tonight due to light and variable winds.
A low pressure center centered off the Socal coast near 33N/120W is spreading mid level clouds into our area today. With the deeper moisture from this system remaining south of our area, precipitation is not expected in our area as the low moves inland and eastward across Socal tonight. SREF indicating upper ridging builds back into central CA on Sunday behind the departed low. The ridge will bring clearing skies and afternoon temepratures are expected to recover some as heights and thicknesses rise.
Maybe a smidge cooler than today, but otherwise a very similar day. Depth of column saturation is still uncertain; some forecast soundings show a bit dryness in the low levels, while RAP fully saturates briefly.
542 PM CST Sat Jan 29 2022 A mid/upper ridge was centered across the Central Great Basin area while a vigorous storm system was impacting the Mid-Atlantic and Northeast.
Upper low enters southwester NM Sunday morning, traversing south-central NM by the end of the TAF period. A ridge of high pressure currently over New Mexico will move east tonight as a closed low aloft approaches. The low will cross the southern part of the state Sunday before moving into TX Sunday night.
Will lean toward the lower amounts and will keep snow totals mainly under a half inch. Do expect clouds will hold up temps again tonight, so will lean toward the warmer guidance. clipper system will exit to the south and east with weak ridging pushing over the area in the morning. This should keep most of the area dry, but a few flurries will be possible where the low clouds exist. Sunday night is expected to be dry, as high pressure shifts east across the region.
High pressure providing clear skies nearly all of central PA this evening. A minor short wave trough aloft will bring in some clouds to the west late. The short wave trough moving across the area this period night will mainly make clouds.
After the chilly start in the teens this morning, temperatures have warmed quite a bit this afternoon with latest readings in the low to mid 20s on the Plateau and the upper 20s to mid 30s elsewhere. Much warmer conditions are on the way tomorrow with highs around 20 to 30 degrees above what we're seeing today in the mid 40s to low 50s.
Low temperatures are expected to be in the lower teens to around 20. little change in the upper level pattern expected during the day while during the night we watch an approaching upper level trough from the northwest. This area will have the cooler high temperatures in the middle 40s to around 50 while elsewhere highs are expected to be in the middle to upper 50s. Low temperatures are expected to be in the lower teens to lower 20s.
Otherwise the high clouds will thin out into the evening. Weakening low pressure and its cold front over MN will track across central and srn WI after midnight. So went a little warmer with low temps.
High pressure will continue to bring dry/cold conditions and overall clear skies through early Sunday. Expect at least one more night of warmer mountain temperatures than valley temperatures. Very cold temperatures, below freezing in valleys, will continue each morning.
Farther west, temperatures have reached the mid-40s and upper-30s as we continue to sit under the eastern side of an upper level ridge over much of the western CONUS. While pressure gradients along the Laramie Range will remain elevated overnight which could lead to a few strong wind gusts around 55 mph near Bordeaux, a trough entering the PacNW Sunday night will break down the 500mb ridge and further tighten pressure/height gradients across the region.
High pressure will continue to dominate the weather pattern over the Southeast U.
Look for elevated srly winds to return by late morning as the gradient tightens behind departing high pressure.
952 PM EST Sat Jan 29 2022 Below normal temperatures will continue overnight as Arctic high pressure shifts to the east.
High pressure will slide to the east today leading to light northwesterly winds through tonight, shifting to a southerly direction tomorrow.
925 PM EST Sat Jan 29 2022 Arctic high pressure will build across the Southeast through tonight, ahead of a moisture-starved clipper low that will cross the central Appalachians and southern Mid Atlantic Sunday and Sunday night. At the surface, high pressure will remain anchored across FL on Sunday, and a fast-moving clipper low will dive from the Midwest early Sunday to across NC/VA by late Sunday night. Dry air in the lower levels will remain across central NC early in the day, with dewpoint temperatures still in the single digits. A lack of sufficient forcing and moisture in the lower- levels will yield dry weather throughout the period as the two systems move by central NC. Highs will increase around 10 degrees compared to Saturday, ranging from the low to mid-40s.
NW flow aloft is well established from the Midwest into the Ohio Valley as the deep closed low heads up into New England. Temps will only run slightly below seasonal normals on Sunday as a sfc trof drags through behind the Clipper, with a wind shift as its only sensible wx impact.
545 PM EST Sat Jan 29 2022 Arctic high pressure will build across the Southeast through tonight, ahead of a moisture-starved clipper low that will cross the central Appalachians and southern Mid Atlantic Sunday and Sunday night. At the surface, high pressure will remain anchored across FL on Sunday, and a fast-moving clipper low will dive from the Midwest early Sunday to across NC/VA by late Sunday night. Dry air in the lower levels will remain across central NC early in the day, with dewpoint temperatures still in the single digits. A lack of sufficient forcing and moisture in the lower- levels will yield dry weather throughout the period as the two systems move by central NC. Highs will increase around 10 degrees compared to Saturday, ranging from the low to mid-40s.
The ridge will continue to be the dominate force through the remainder of the weekend. Overnight expecting the winds to keep the temperatures a little warmer, much like last night.
