557 AM CST Sun Feb 6 2022 H5 analysis tonight had a low off the coast of Baja California with high pressure noted off the northern California coast. Ridging extended north of the high into northern British Columbia. A cold front extended northwest of the low with a warm front extending southeast into southwestern Minnesota. this feature will force a cold front through the forecast area this morning with the bulk of the arctic air off to the northeast of the forecast area.
654 AM EST Sun Feb 6 2022 High pressure will start the day overhead, but start to slide eastward through the day. Upper level ridging will keep it dry today. Warm advection/southerly flow ahead of approaching upper trough, combined with a fair amount of sun, should push temperatures a few degrees above average Monday afternoon. By late in the day a cold front will approach northwest PA. The low is moving a little too quickly to throw precip more than a trace back into the CWA.
(Today and tonight) An upper trough will move from the northern Plains into the Midwest today, and become more elongated as its southern portion shifts south across West Texas tonight. Associated cold front will be weak for our area, with mainly just a wind shift. Ahead of this front, weak downsloping southwest to west winds and sunny skies will allow for warmer temperatures compared to yesterday. Highs are expected to be in the lower to mid 50s across the southern half of our area, with the warmest readings along the I-10 corridor. With the proximity of the mid/upper level trough may have a few patchy clouds tonight.
Below normal temperatures will trend warmer today and Monday.
/Issued 339 AM CST Sun Feb 6 2022/ A cold front is now clearing the southeast Texas Panhandle. North winds are expected to pick up into the 20 to 30 mph range with higher gusts by late this morning as a positively tilted upper level trough moves across the Panhandles and cold air advection increases.
246 AM PST Sun Feb 6 2022 The current dry period will extend through at least mid-month as high pressure remains overhead. An upper-level long-wave ridge, which has given us quiet and dry weather, will slowly amplify and shift east over the western US by mid-week.
This warms temperatures around 10 degrees today and be a few degrees warmer tonight and early Monday morning. Upper level flow has become more zonal behind departing trough now far to the east and upper level ridge over the far western states. To the north a low pressure area and upper level trough moves into the Great lakes today and tonight. A weak front moves into the Ohio Valley by early Monday morning ahead of the upper trough. Also to the south a frontal boundary over south Florida will hang out there then low pressure off the Florida east coast will drift north toward South Carolina by Monday morning.
345 AM CST Sun Feb 6 2022 Clear skies and nearly calm winds have allowed temperatures to fall below freezing areawide with the exception of the immediate coastline. High pressure ridging across much of the northern and western gulf coasts will maintain the tranquil weather conditions through the day. As this ridge begins to lift northeast, some mid and upper level moisture will lift back onshore resulting in increasing cloud cover late tonight into Monday. The cloud cover will keep Monday morning lows several degrees warmer although a light freeze will still be possible across central Louisiana and interior southeast Texas. An upper trof digging south across the central U.
The morning temperatures are also cooler than 24 hours ago with observations reporting temps in the mid to upper 50's.
345 AM CST Sun Feb 6 2022 A much needed break in the weather realm this week as high pressure settles into the region. We will be slightly warmer today to allow for more melting of residual ice across the Mid South.
418 AM CST Sun Feb 6 2022 Clouds will increase during today as a cold front approaches northwest IL by sunset. Milder highs today in the low to mid 30s with southerly breezes. A period of patchy freezing drizzle is expected tonight as the cold front moves through the area.
Easterly flow around the bottom side of a low level ridge along the Appalachian Mountain range will push Atlantic moisture into southeast Alabama later this morning. An upper level short wave trof will approach the MS river on Monday, and model consensus shows a band of showers developing across the western portions of the Fl panhandle, southeast Alabama, and southern Georgia Monday afternoon. Drier air behind a weak cold front will erode the clouds from west to east Monday afternoon.
Ongoing tranquil conditions will continue throughout the period despite an upper level trough of low pressure pushing southeast across the Western High Plains today, ushering a weak attendant front through western Kansas. Slightly cooler air will filter southward into western Kansas today in wake of the weak frontal passage this morning, dropping H85 temperatures a little below 0C across central and much of southwest Kansas. A dry pattern will persist through at least the middle part of the week as a northwest flow flow aloft prevails across the Western High Plains while much drier air in the lower/mid levels dominates the region. Above normal temperatures are likely Monday as a westerly downslope flow draws warmer air into western Kansas, pushing H85 temperatures well up into the single digits(C).
SHORT TERM (Today through Monday): Today will be warmer and dry before low to mid level moisture increases across northeast Mexico and deep south Texas into the western Gulf of Mexico tonight and continues to increase across the area Monday as a 500mb trough continues to develop across southern Rockies and northwest Mexico today and moves across northwest Texas tonight into west Texas and northern Mexico Monday. The upper level jet will enhance the potential for elevated convection tonight into Monday as a coastal trough develops across the western Gulf of Mexico. Wind advisories may be needed for the coastal sections of the coastal counties Monday as strong north winds develop across the lower Texas coast.
Temperatures will increase even more the next couple days, with highs possibly reaching the low 60s Monday afternoon, but for sure the 50s across the entire area. Vertz Models are continuing to show the weather pattern dominated by a ridge centered west of the area, putting the area under northwest flow.
Associated cold front is through all of northeast Colorado with northerly winds of 10-20kt. Main impact for this afternoon will be the cooler temperatures behind the front with readings only in the 30s today. Ridging aloft will be building over the Northern Rockies with a moderate northerly flow over Colorado for tonight. Temperatures will be on the rise Monday under weak ridging aloft, with highs climbing 5-10 degrees in the high country, and 10-15 degrees east of the mountains.
/22/ Today and Tonight: Continued dry through the period and although temperatures will be colder than normal, they will be warmer than the last couple of days. Early morning surface analysis had a northeast to southwest oriented ridge axis across our CWA. This ridge axis will weaken slightly through tonight but remain in place. This will lead to afternoon temperatures topping out in the low to mid 50s while morning lows Monday bottom out in the upper 20s to lower 30s. By Monday, another midlevel trough digging through the Southern Plains will be present and looks to swing through the Lower Mississippi Valley by midweek.
This afternoon will be warmer as winds become southerly with sunny skies. High pressure keeps VFR conditions and light winds through the entire period.

529 AM EST Sun Feb 6 2022 Upper air pattern consists of a 500 mb trough in the upper Great Lakes this morning. Continued upstream ridging and board troughing across the eastern third of Canada and CONUS is expected. This will place Upper Michigan on the road for any system dropping out of Canada and into the trough. Expect activity to wind down through the day though as the ridge settles in.
Strongest wind expected through favorable oriented gaps and canyons, and over ridges.
High temperatures today are expected to reach the lower to mid 50s across the region with plentiful sunshine. It will somewhat keep temperatures at bay on Monday with very similar afternoon highs expected, ranging from the lower to upper 50s.
515 AM EST Sun Feb 6 2022 A ridge parked near the Pacific Northwest gives way to a positively-tilted trough over the Plains. A TUTT-like cell pressing southwest through the eastern Caribbean has pinched the mean layer ridging near the Keys into a narrow axis bisecting Cuba.
/issued 345 AM CST Sun Feb 6 2022/ A much needed break in the weather realm this week as high pressure settles into the region. We will be slightly warmer today to allow for more melting of residual ice across the Mid South.
327 AM CST Sun Feb 6 2022 A weak surface cold front continues to move through the forecast area this morning. Cooler temperatures are expected today behind the cold front with highs ranging in the upper 30s to the upper 40s however gusty northwest winds will create wind chills in the 20s throughout much of the day.
629 AM EST Sun Feb 6 2022 High pressure brings a dry finish to the weekend, with a milder afternoon today. A weak cold front arrives Monday night with light snow possible, followed by high pressure. Diurnal heating and a contribution of light southerly flow will permit temperatures to climb into the mid 40s across the lowlands, and into the mid 20s northeast mountains. Monday starts the short term period off dry as high pressure exits off to the northeast. Temperatures on Monday will be around seasonable with 40s expected across the lowlands and 30s to 40s along the higher elevations.
504 AM CST Sun Feb 6 2022 (Today) Positively tilted long wave trough will swing through the area today with a weak frontal boundary moving through during the afternoon. Boundary will have little impact on temperatures and we will likely see slightly warmer conditions compared to yesterday. Deeper snow cover, mainly across northwest Arkansas, will keep temps a few degrees cooler than otherwise.
Today Through Monday Night Latest sfc data shows a high pres ridge aligned along the MS River early this mrng. Cannot rule out some patchy fog/freezing fog toward sunrise. Another day of abundant sunshine wl allow highs to top out in the lower 40s to mid 50s. A weak sfc trof/ wind shift wl slide thru the FA by early Mon, ahead of a mid lvl trof. Other than some incrs in clouds with this sys, look for a repeat in temps for Mon/Mon night, with highs in the lower 40s to mid 50s and lows in the 20s.
444 AM EST Sun Feb 6 2022 High pressure will start the day overhead, but start to slide eastward through the day. Upper level ridging will keep it dry today. Warm advection/southerly flow ahead of approaching upper trough, combined with a fair amount of sun, should push temperatures a few degrees above average Monday afternoon. By late in the day a cold front will approach northwest PA. The low is moving a little too quickly to throw precip more than a trace back into the CWA.
NBM for today was actually colder than yesterday while the 850mb temps are 4 to 5*C warmer than yesterday. Therefore, the warmer solutions of EC and Canadian are more likely.
634 AM EST Sun Feb 6 2022 High pressure will provide mostly sunny skies today and kick off a gradual warming trend today into Monday. High pressure shifts off to our east and warm air advection occurs as SW return flow develops. High pressure remains in control tomorrow with southerly flow continuing to pump some warmer air into the region. Highs will feel almost tropical, as the warmest spots top out in the low 40s, and most of the area will be in the mid to upper 30s. 350 AM Update: Monday night, an area of low pressure will track off the southern New England/Mid-Atlantic coast.
With clear skies, calm winds, and low dewpoint depressions, cannot rule out a bit of patchy freezing fog in a few spots but this appears unlikely.
342 AM CST Sun Feb 6 2022 Today and Tonight: Continued dry through the period and although temperatures will be colder than normal, they will be warmer than the last couple of days. Early morning surface analysis had a northeast to southwest oriented ridge axis across our CWA. This ridge axis will weaken slightly through tonight but remain in place. This will lead to afternoon temperatures topping out in the low to mid 50s while morning lows Monday bottom out in the upper 20s to lower 30s. By Monday, another midlevel trough digging through the Southern Plains will be present and looks to swing through the Lower Mississippi Valley by midweek.
559 AM CST Sun Feb 6 2022 Clouds will increase during today as a cold front approaches northwest IL by sunset. Milder highs today in the low to mid 30s are expected with southerly breezes. A period of patchy freezing drizzle is expected tonight as the cold front moves through the area.
326 AM CST Sun Feb 6 2022 Absolutely tranquil weather across the region early this morning, with high pressure continuing to promote a clear sky and dry conditions. In response to this area of high pressure shifting east of the area, our winds will veer to the south today. This will result in a welcome warm-up as this southerly flow combined with abundant sunshine will nudge our temperatures into the lower 50s by this afternoon (about 10-15 degrees higher than yesterday).
1109 AM CST Sun Feb 6 2022 (Today and tonight) An upper trough will move from the northern Plains into the Midwest today, and become more elongated as its southern portion shifts south across West Texas tonight. Associated cold front will be weak for our area, with mainly just a wind shift. Ahead of this front, weak downsloping southwest to west winds and sunny skies will allow for warmer temperatures compared to yesterday. Highs are expected to be in the lower to mid 50s across the southern half of our area, with the warmest readings along the I-10 corridor. With the proximity of the mid/upper level trough may have a few patchy clouds tonight.
A retreating high pressure center will move east with dry west to southwest flow prevailing locally.
Looking at visible satellite and our office rooftop camera, we can see that it still persists mainly west of the Seven Mile Bridge. Dense Fog Advisory remains in effect through the remainder of this morning for the waters adjacent to and north of the Lower and Middle Keys.
A stalled frontal boundary is situated over South Florida, along with an area of low pressure developing east of the peninsula over the Atlantic waters.
A weak upper low on the Gulf coast and another weak cold front we be arriving into our four state area and will shift winds to NW before daybreak. This weak cold front will basically keep highs in the mid 50 range again tomorrow.
/issued 1059 AM CST Sun Feb 6 2022/ Surface analysis late this morning centers a ridge of high pressure over New England and stretching back into the Tennessee and Lower Mississippi Valley. Southerly winds on the back side of high pressure will help to moderate temperatures into this afternoon. /issued 345 AM CST Sun Feb 6 2022/ A much needed break in the weather realm this week as high pressure settles into the region. We will be slightly warmer today to allow for more melting of residual ice across the Mid South.
High pressure and clear skies will prevail across the ArkLaMis today, with high temperatures ranging from the upper 40s across the Delta to the mid 50s in the south. /15/ Prior discussion below: Today and Tonight: Continued dry through the period and although temperatures will be colder than normal, they will be warmer than the last couple of days. Early morning surface analysis had a northeast to southwest oriented ridge axis across our CWA. This ridge axis will weaken slightly through tonight but remain in place. This will lead to afternoon temperatures topping out in the low to mid 50s while morning lows Monday bottom out in the upper 20s to lower 30s. By Monday, another midlevel trough digging through the Southern Plains will be present and looks to swing through the Lower Mississippi Valley by midweek.
Another cold start but a beautiful morning in progress for the Tennessee Valley, as temperatures have climbed above the freezing mark. This will result in warmer temperatures throughout the day today, with most places reaching the lower 50s this afternoon.
A weak cold front will move through the region tonight. A weak cold front moves into far northwestern areas late this afternoon and across the remainder of our area tonight. Weak cold advection behind the front and along with some clouds ahead of an upper level trough may cool off high temperatures about a degree or two on Monday, if at all.
/15/ High pressure and clear skies will prevail across the ArkLaMis today, with high temperatures ranging from the upper 40s across the Delta to the mid 50s in the south. /15/ Prior discussion below: Today and Tonight: Continued dry through the period and although temperatures will be colder than normal, they will be warmer than the last couple of days. Early morning surface analysis had a northeast to southwest oriented ridge axis across our CWA. This ridge axis will weaken slightly through tonight but remain in place. This will lead to afternoon temperatures topping out in the low to mid 50s while morning lows Monday bottom out in the upper 20s to lower 30s. By Monday, another midlevel trough digging through the Southern Plains will be present and looks to swing through the Lower Mississippi Valley by midweek.
144 PM MST Sun Feb 6 2022 A weak low pressure system passing by to our east this evening will result in dry and breezy conditions through Monday. A warming trend is then expected through midweek as high pressure builds across the intermountain West. PWATs remain below average and no precipitation is expected from this trough. Slightly cooler conditions are likely Monday in the wake of the trough. Thereafter, a warming trend is anticipated through the week as a series of ridges build across the eastern Pacific and western CONUS.
217 PM CST Sun Feb 6 2022 The combination of cold air advection, steep 925-900 mb lapse rates, and low level moisture has resulted in the possibility of freezing drizzle in southeast Minnesota through 3 PM and northeast Iowa through 5 PM. For tonight, high pressure will gradually build across the area. The chances for some light precipitation will be tied to a couple of short wave troughs moving through the flow.
An upper level trough shifts across the area Monday which will help to usher in increased low level clouds and perhaps a few rain showers southeast of the I-65 corridor. Temperatures warm into the middle to upper 50's for most locations this afternoon, and dip into the lower to middle 30's inland and middle to upper 30's southeast of the I-65 corridor. Cloud cover over the area may limit forecast highs to a couple degrees cooler than today, expecting middle 50's for most locations Monday.
Since then things have quickly changed again for the western waters and the Lower Keys. A surge coming down the west coast of Florida associated with cold air advection has led to an outbreak in low stratus and cooler temperatures.
The best location for the bulls-eye for the heaviest rain is between McAllen and the Gulf of Mexico, with general 1" to 2" rainfall totals possible, especially over the Lower and Middle Rio Grande Valley. Meanwhile, those in the Rio Grande Plains and Brush Country, where the rain chances end earlier, could see enough sunshine to pop back into the lower 60s.
202 PM CST Sun Feb 6 2022 High pressure will briefly slide southeast through the eastern cwa this afternoon effectively cutting off any lingering flurries or snow showers.
904 AM CST Sun Feb 6 2022 Brief zone update for expiration of Freeze/Hard Freeze Warnings as temperatures have warmed well above freezing.
1137 AM CST Sun Feb 6 2022 Surface ridging is slowly departing to the east this morning under clear skies. Southerly flow will advect milder air into the region with mostly clear skies aiding to push temperatures well above freezing this afternoon. A cold front will approach from the northwest late this evening into the overnight period. Dry air and high pressure will clear most of the cloud cover, but most locations will run around 5-7 degrees cooler than Sunday behind the cold front.
/issued 1026 AM CST Sun Feb 6 2022/ Gorgeous day going with full sunshine and 10am readings 5 to 10 degrees warmer than this time yesterday. We have just a couple of upper 30s left well north of I-30 with most locales in the lower 40s. The winds are light and now from the south in the wake of departing cold high pressure of 1029mb over N AL. High temperatures today are expected to reach the lower to mid 50s across the region with plentiful sunshine. It will somewhat keep temperatures at bay on Monday with very similar afternoon highs expected, ranging from the lower to upper 50s.
High pressure is exerting its influence over the Northern Rockies currently. Tomorrow, a weak wave flattens the ridge and may bring light snow showers to the mountains of northwest Montana. The bigger story will be the ridge amplifying as the wave moves east. The 10th or 11th of February will be the peak of this ridge, as another wave initiates the breakdown of the ridge by week's end. The ridge axis is expected to stay to our west so this will not be a traditional winter high pressure with strong valley temperature inversions, daily fog, and air quality issues. We do expect temperatures about 5 to 10 degrees warmer than normal. We watch the PNA closely to gauge whether a ridge or trough is the dominant feature over the west coast. Continued high pressure is expected through Monday.
251 PM CST Sun Feb 6 2022 Afternoon temperatures have climbed into the lower 50s across much of the Valley, as large scale subsidence and dry air keeps sunny skies around. Could see some patchy fog/freezing fog development, but confidence was not high enough to include in the forecast at this time. Not much change to the forecast in the short term, as high temperatures look very similar on Monday, topping out in the lower 50s. A positively tilted upper trough axis will begin to center over the Valley tomorrow night, and a dry front is expected to move through the area.
Surface analysis late this morning centers a ridge of high pressure over New England and stretching back into the Tennessee and Lower Mississippi Valley. Southerly winds on the back side of high pressure will help to moderate temperatures into this afternoon. /issued 345 AM CST Sun Feb 6 2022/ A much needed break in the weather realm this week as high pressure settles into the region. We will be slightly warmer today to allow for more melting of residual ice across the Mid South.
935 AM CST Sun Feb 6 2022 Another cold start but a beautiful morning in progress for the Tennessee Valley, as temperatures have climbed above the freezing mark. This will result in warmer temperatures throughout the day today, with most places reaching the lower 50s this afternoon.
227 PM CST Sun Feb 6 2022 Forecast Key Points: - Well above average temperatures this week - Dry conditions this week - Elevated fire danger this Week A weak cold front has pushed through the area. Temperatures cloud climb into the low 60s across portions of the area.
1130 AM CST Sun Feb 6 2022 H5 analysis tonight had a low off the coast of Baja California with high pressure noted off the northern California coast. Ridging extended north of the high into northern British Columbia. A cold front extended northwest of the low with a warm front extending southeast into southwestern Minnesota. this feature will force a cold front through the forecast area this morning with the bulk of the arctic air off to the northeast of the forecast area.
