626 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 with mid level clouds developing this evening. Temperatures look to trend warmer, ranging from 30 north to 40 south. Expect lows to range from the lower teens north to the lower 20s south.
Temperature inversions may keep the southwest valleys cooler than other locations.
/issued 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.
High pressure providing clear skies nearly all of central PA late this evening. A minor short wave trough aloft will bring in some clouds to the west late. A short wave trough moving late Sunday and Sunday night will be moisture challenged, with the main sensible weather being an increase in clouds.
/Issued 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.
Quiet and warmer weather is expected over the next few days, as upper level ridging builds over the central CONUS through Monday. Near- normal temperatures today and Sunday will peak on, with temperatures expected to reach the freezing mark across most of the area for the first time since mid- January.
Tonight Through Monday A large upper trough will be over the east coast this evening with a strong upper ridge over the western states and a weak upper low over southern California. Northwest flow over Arkansas will continue through Monday as the upper low slides through Texas. High pressure and clear skies are over Arkansas this afternoon and will continue tonight and Sunday.
Latest WPC surface analysis places arctic high pressure across the Ohio Valley region. High pressure will continue to shift eastward tonight, giving way to some warm advection. This will result in slightly warmer overnight temperatures relative to last night with lows will be in the upper 20s to low 30s. A dry cold front will pass through the region on Sunday with a slight wind shift during the late afternoon hours. 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.
Upper low enters southwestern NM Sunday morning, traversing south-central NM through the 00Z hour. 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. Monday will be nice and warmer.
1114 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. Breezy southerly winds will advect low level moisture into central and eastern Kansas on Monday while the H85 thermal ridge is sheared eastward helping to drive highs into the mid 60s for many areas which is around 20 degrees above normal for late Jan.
This is expected to cut some 5-10 degrees off the high temperatures compared to today's highs. Upper ridge builds back on Monday across the central CONUS ahead of our next period of disturbed weather.
Temperatures are in the 50s across the island chain, limited by the warmer SSTs north of the island chain.
Another chilly night is on tap with temperatures falling into the lower to upper 30s across the region. So with SW flow again tomorrow, expect a warmer day again with high temps edging toward the 70 degree mark.
932 PM CST Sat Jan 29 2022 High pressure overhead will maintain light winds and clear skies overnight. Look for elevated srly winds to return by late morning as the gradient tightens behind departing high pressure.

High clouds will clear out tonight with clear skies and warmer temperatures on Sunday.
1028 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.
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. Rising 500mb heights on Monday will translate into a warmer day across the region with some areas potentially jumping briefly above freezing.
317 AM EST Sun Jan 30 2022 High pressure along with relatively dry air will remain in control of the region through the middle of the week along with a warming trend.
1242 AM EST Sun Jan 30 2022 Below normal temperatures will continue overnight as Arctic high pressure shifts to the east. High pressure will build back into the region again Sunday night into Monday. Temperatures look to trend warmer, ranging from 30 north to 40 south. Expect lows to range from the lower teens north to the lower 20s south. We can expect dry weather Monday under a large area of high pressure.
252 AM CST Sun Jan 30 2022 An upper level ridge will continue to push eastward across the Western U. Today will be a little bit cooler behind a weak front that moved through.
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.
Deep layer flow will remain northwesterly at least for another day with deep troughing located over the eastern US.
249 AM CST Sun Jan 30 2022 An upper level ridge will continue to push eastward across the Western U. Today will be a little bit cooler behind a weak front that moved through.
High pressure will slide to the east today leading to light northwesterly winds through tonight, shifting to a southerly direction tomorrow. Dry conditions continue through Monday as an upper level ridge gets pushed southeast through the area. Lee troughing will be found across eastern Colorado which will bring southerly winds to western Kansas.
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 mb 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. Monday will see the upper level trough quickly progress across the Northern Rockies before exiting to the Northern Great Plains overnight.
208 AM EST Sun Jan 30 2022 High pressure along with relatively dry air will remain in control of the region through the middle of the week along with a warming trend. Ridge of high pressure will be over the forecast area this morning then slide offshore this afternoon. Skies will be mostly clear through the day with some cirrus crossing the region due to weak low pressure passing well north of the area and a weak upper level trough moving through the forecast area. High pressure will continue to dominate the weather pattern over the Southeast U.
/issued 932 PM CST Sat Jan 29 2022/ High pressure overhead will maintain light winds and clear skies overnight. Look for elevated srly winds to return by late morning as the gradient tightens behind departing high pressure.
Highs look to push north of freezing for many locations Mon/Tue. How far south these chances would extend is the main question for this area, with an associated cold front providing some lift. This suggests a few days under the influence of a trough (cold), and a few days under a ridge (milder). Locally, the concern is how far north its associated deformation region would extend - do we get into snow? MID WEEK WINTER STORM: The Tue system hangs a cold front out to the southwest, stretching from the eastern great lakes into the southern plains. MVFR stratus should overspread the area overnight and last into Sunday, but confidence in the duration, start, and end time of the stratus is on the low side.
Upper level winds will continue out of the northwest today and an upper level low pressure center in the desert southwest will slowly move east. Dry conditions continue through Monday as an upper level ridge gets pushed southeast through the area. Lee troughing will be found across eastern Colorado which will bring southerly winds to western Kansas.
A trough trailing from this low will pass through the area Sunday morning, shifting winds from southwesterly to northwesterly during the morning.
Cliff PREVIOUS DISCUSSION: Upper level ridging has moved into the area and will make for a relatively pleasant weekend.
150 AM MST Sun Jan 30 2022 Current surface map places trof across eastern Montana into far western South Dakota. Flat upper level ridge is located across the northern Rockies/Plains. If we could get a break in the high clouds, a few 60s are possible. Upper trof moves in the plains Monday, with initial cold front arriving during the day.
An upper trough will exit the Pacific Northwest and move into the Northern and Central Plains during the afternoon. This will break down the upper ridge and drive a cold front through western South Dakota. Highs across western Nebraska were nudged up to the low 60s in most locations, as southwest winds become west and increase during the afternoon.
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.
/Today through Monday/ Upper-level ridging to prevail across the region today maintaining mostly sunny skies areawide. An upper-level trough to swing east into Texas tonight allowing for gradually increasing unstable southwest flow aloft. Additionally, much warmer temperatures expected with low temperatures ranging from the upper 30s to the mid 40s.
A cold front will move across the area tonight and make a cooler day on Sunday, with highs in the 40s. An upper short wave trough moving across the Dakotas will bring a cold front across the area on Monday night.
Another around of dry, offshore winds will develop late Monday through midweek across the Bay Area and Central Coast peaks and ridges.
1058 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).
An upper level trough and associated cold front will move through the region late Sunday night and Monday morning, bringing snow to the mountains and ending the surface inversion in lower elevations. The forecast calls for around an in in McCall, with only 1 to 2 inches for most of the mountains, ranging up to 2 to 3 inches on the highest peaks. As often happens after an inversion, Monday afternoon's high temps will be warmer than today or Sunday even though a "cold" front will have moved through. Only the higher elevations in the northern mountains will actually be colder Monday than Sunday.
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. Southwest winds continue on Monday, and it will likely be another unseasonably warm day as the upper trough moves overhead.
1217 AM EST Sun Jan 30 2022 Cold high pressure will prevail through Sunday. A warming trend is then expected ahead of a cold front, which may approach the area by late week. Even winds at the coast will diminish over the next few hours as high pressure builds in. At the beaches, a light drainage wind should push upper 20s to the beaches with a hard freezing occurring some beach areas that do not normally see such conditions. A broad upper trough will be departing off the U.
Another very cold start today under high pressure with many locations again below zero. Upper level ridge breaks down today as Pacific trof advances quickly east Monday. It will drive through a strong cold front. With increasing cloud cover tonight low temperatures will be much warmer than the previous several days and much closer to seasonal normals for the end of January. Lows Monday night will be cooler than tonight as colder air moves in again with likely inversion conditions setting in with northerly flow aloft.
Temps this morning were a couple degrees cooler than forecast, so tweaked the near-term temp trend to account for this. Highs are still on track to reach the lower 50s to lower 60s under a sunny sky. This will aid in temperatures trending warmer with highs in the upper 50s north of I20 and mid to upper 60s south of I20.
Lifting/mixing out of the low cloud layer should yield a fair amount of sun over the NW half or so of the area, with clouds hanging in a little tougher to the SE where the depth of the moist layer is greater. Temperatures this afternoon will push the mid 80s over interior E TX into Central LA with "cooler" readings in the lower 80s/upper 70s near the coast and over SC LA via the moderating affects of water and greater cloud cover. Confidence decreases by TUE, with the primary culprit an upper low progged to translate east along the Rio Grande and through the Gulf Coast States. Global model solutions vary from a progressive opening/weakening trof to a slower/closed upper low.
312 AM PST Wed Feb 8 2017 A few showers will dissipate this morning with dry weather forecast this afternoon as moisture decreases under a building ridge. The ridge will result in a fairly warm day today and even warmer conditions on Thursday.
846 AM EST Wed Feb 8 2017 APPROACHING COLD FRONT WILL REMAIN NORTH OF THE REGION FOR THIS AFTERNOON.
315 AM PST Wed Feb 8 2017 A few showers will dissipate this morning with dry weather forecast this afternoon as moisture decreases under a building ridge. The ridge will result in a fairly warm day today and even warmer conditions on Thursday.
Winds will shift from SW to NW and stay up overnight as a cold front pushes through the area.
Warm frontal precipitation will continue to invade the area, becoming more intense this afternoon. The warm air moving in aloft over the cold surface air will create the set up for a change from snow to freezing rain later today. By noon the freezing rain will likely spread throughout the I-84 corridor all the way to Pendleton. and this one will bring snow and freezing rain to portions of central and northeast Oregon and south central and southeast Washington today and tonight. KRDM should warm above freezing by the time precipitation arrives around 19Z so both KBDN and KRDM should observe only rain and occasional MVFR conditions. The other terminal airports will not be so lucky and snow, sleet and freezing rain will affect travel.
High temperatures today will be in the lower 30s across much of the area, with lows tonight mainly in the teens. Sub-freezing temperatures will prevail Thursday and Thursday night as an upper trough shifts east across the Midwest.
415 AM CST Wed Feb 8 2017 Westerly flow will transition to a northerly flow today as a cold front moves across the area. The front may not make it to the southern areas so have kept warmer temperatures to the south while a cooldown is expected across the OK Panhandle and eastern TX Panhandle. Winds will shift back out of the southwest this evening and during the day Thursday due to a lee side trough, but the eastern Panhandles may still be under the northerly flow and have cooler temperatures.
Given fairly calm conditions and plenty of moisture trapped within the lowest levels, the reduced visibilities will continue through the remainder of the morning. It seems that the highest risk of strong to severe thunderstorms will be along and north of a line from LaFayette to Cleveland. The cold front will quickly sweep this activity east of the area by early Thursday morning. Behind the front a tight pressure gradient will lead to a windy Thursday as cooler temperatures are ushered into the area. Much cooler high temperatures will range from the 40s north to lower 60s in central Georgia. RW 500mb longwave trough will continue moving offshore Thursday night.
A cold front will slowly move NE to SW across West Texas today though the primary influences will be limited to changing wind direction. A cold front which is making its way across western Oklahoma will back door across our area today filtering somewhat cooler and drier air into the area tonight as high pressure passes to our northeast tomorrow morning. Though a cold front will have pushed through the region on Wednesday, a quick return of southerly flow on Thursday will keep temperatures from cooling much. In fact, though we'll be around 10 degrees cooler than Wednesday, we'll still be around 10 degrees above climate normals.
Winds will be the main focus as a cold front continues to move across the Panhandles. /Issued 415 AM CST Wed Feb 8 2017/ Westerly flow will transition to a northerly flow today as a cold front moves across the area. The front may not make it to the southern areas so have kept warmer temperatures to the south while a cooldown is expected across the OK Panhandle and eastern TX Panhandle. Winds will shift back out of the southwest this evening and during the day Thursday due to a lee side trough, but the eastern Panhandles may still be under the northerly flow and have cooler temperatures.
Incrsg N/NW winds wl usher much cooler and drier air into the area. Light N/NELY winds were noted behind the fnt, with the assocd cooler air still lagging back acrs NRN AR. Predawn temps ranged fm the lower 40s to the mid 50s. Temps in the N wl be cooler, generally in the 60s. The real push of cooler air wl occur tngt and Thu.
754 AM EST Wed Feb 8 2017 Scattered showers will end this morning as a cold front moves across the area. Snow is expected late tonight into early Thursday morning with the highest accumulations likely in the Lower Susquehanna Valley.
656 AM EST Wed Feb 8 2017 Scattered showers will end this morning as a cold front moves across the area. Snow is expected late tonight into early Thursday morning with the highest accumulations likely in the Lower Susquehanna Valley.
Meanwhile, ridging will build over the Northern Rockies with leeside troffing developing at the surface, setting up a period of strong downsloping across the area with increasing temperatures and strong gap flow winds.
Otherwise, VFR conditions will persist as winds in the lower atmosphere trend down through the day. As an upper level ridge of high pressure begins building in from the west this afternoon, strong northwest winds from the central mountains east will subside.
526 AM CST Wed Feb 8 2017 Drier and warmer weather ahead. Much of this period will be marked by change, with the current 500mb ridge moving into the western states and the dominant trough set up across much of the rest of the nation slowly shifting to the eastern half of the nation. By 06Z tonight the 500mb map should show a full ridge over the western half of the nation, and a trough over the east.
A prefrontal trough will push through the region today, shifting winds to the west/northwest, and bringing drier air into the region. Expect highs today to reach the lower 90s across much of the region. A return closer to normalcy will come as a cold front moves through the region tonight, with lows in the mid 50s to low 60s. Temperatures tomorrow will be several degrees cooler (though still well above normal), with highs in the 70s across the region.
1016 AM EST Wed Feb 8 2017 Scattered showers will end this morning as a cold front moves southeast of the region. Behind this, upslope snow will continue into Thursday afternoon, enhanced somewhat by passage of the mid level trough. Have issued a winter storm warning for the higher eastern Tucker and Garrett, closer to best moisture and where synoptic snow looks to hold on longest. Winter weather advisory has been issued for the remainder of the ridges and up to Indiana county. Outside of the ridges, lesser amounts should stay under advisory criteria, although Monongalia and Marion counties in will need to be monitored for headlines, as they will be closer to better lift and deep moisture.
VFR conditions with veering winds will occur today as a weak prefrontal trough moves into Deep South Texas and the Rio Grande Valley. The passage of a cold front tonight will continue the veering wind trend and VFR likelihood. Otherwise, the approach and passage of a prefrontal trough today will have the ability to create a second consecutive day of record high temperatures. Relief will come in the form of a cold front passage around midnight tonight, which will knock overnight low and daytime high temperatures down a few degrees but still prevailing at well above normal levels. Relatively dry air will prevent any precipitation from developing despite the trough and frontal passages.
A cold front will move across the terminals today with frontal passage at the northern terminals between 16Z and 18Z and at the southern terminals between 18Z and 20Z. A dry cold front will move into the Big Country later this morning and will be along the I-10 corridor by mid-afternoon. Cold air advection will be weak with highs ranging from the upper 70s in the Big Country to the lower 80s farther south. (Thursday through Wednesday) Thursday behind the cold front still looks to be the coolest day of the work week, with temperatures dropping 10 to 20 degrees across the area. However, with afternoon highs ranging from the low 60s across the Northern Big Country to the lower 70s near San Angelo, temperatures will still be 5 to 10 degrees above normal.
423 AM CST Wed Feb 8 2017 Currently, A cold front is bisecting the CWA along a line from just south of Paris Tennessee back west to just south of Jonesboro Arkansas. Cooler air will funnel in behind the front overnight, and temperatures will fall into the upper 20s across the north to the lower 30 across the south.
530 AM CST Wed Feb 8 2017 At 3 AM, a short wave trough was moving southeast through Iowa. Subsidence in the wake of the departing short wave trough will allow skies to gradually clear today. The high temperatures (13 to 23F) for today will be mainly this morning and only climb 1 to 3F this afternoon. For this evening, another short wave trough will move quickly southeast through the region.
COLD FRONT STILL SET TO MOVE IN LATE AFTERNOON/EARLY EVENING BRINING ANOTHER ROUND OF BKN CIGS. SOME OF THESE SHOWERS MAY PRODUCE SMALL HAIL AS FREEZING HEIGHTS WILL BE LOWERING THROUGH THE DAY WITH COLD AIR ALOFT MOVING IN WITH TROUGH.
909 AM EDT WED MAY 4 2016 COOL LOW PRESSURE WILL KEEP SHOWERS IN THE FORECAST THROUGH THURSDAY.
