544 PM EST Sun Dec 25 2016 Aviation Freezing rain and rain will move into Lower Michigan this evening as a blizzard moves though the Dakotas.
As a result, we extended the Freezing Rain Advisory for northeast Iowa and southeast Minnesota until 6 PM. North-central Wisconsin has only seen a light freezing rain so far. Strong 800 to 700 mb frontogenesis (associated with the elevated warm front) has resulted in scattered thunderstorms developing between Mankato Minnesota and Madison Wisconsin. Temperatures ahead of the cold front will climb into the 40s across much of the area tonight. This will bring an end to the freezing rain threat.
Thin line of heavier showers associated with a cold front will continue to push eastward, affecting all the terminals except BVO in the next 6 hours. A pacific cold front trailing the parent low pressure had shifted eastward across Central Kansas to Osage/Pawnee counties in Northeast Oklahoma and extended southwest through Southwest Oklahoma and Western Texas. The exception could be any convectively driven winds focused along/just out ahead of the cold front as gusts in the 50 to 60 mph range were reported over Western/Central Oklahoma earlier today. the cold front will continue to slide east through the CWA. Behind the pacific cold front.
1017 PM EST Sun Dec 25 2016 A warm front will bring a chance of light showers early Monday morning continuing through much of the day. Temperatures could be cold enough in the morning for a brief period of freezing rain.
604 PM CST Sun Dec 25 2016 The vigorous mid/upper trough responsible for our windy and stormy weather conditions will move rapidly north and east across the Northern Plains and into the Upper Mississippi Valley area by early Monday morning. As high pressure settles over the area Mon night, radiational cooling will allow lows to fall into the low to mid 20s. A mid/upper trough is progged to dig over the Central Great Basin/Southwest States as we move into the weekend bringing an increasing chance for precipitation to the area late in the weekend.
Confidence remained high with moving the upper low to a position southwest of the Southern California Coast.
637 PM EST Sun Dec 25 2016 A warm front lifts northeast tonight.
939 PM CST Sun Dec 25 2016 Starting to see scattered lightning across south central North Dakota between Mobridge SD and Linton ND. Otherwise concerns about the timing of freezing rain to snow southeast. Its possible the precipitation (rain/freezing rain/sleet) will trail off before the snow and winds increases late tonight. Snow, some of it heavy, was falling over most of the forecast area outside of the southern James River Valley where freezing rain continued. Colder behind the exiting storm, warmer for mid week, then colder again to end the week into the New Year's Holiday Weekend. Main hazard to aviation will be widespread blizzard conditions across west and central North Dakota with freezing rain and sleet at KJMS changing to snow.
600 PM EST Sun Dec 25 2016 A warm front will bring a chance for light rain tonight and early Monday. A better chance arrives with a Monday night cold front. This is especially true west of the ridges, ahead of the advancing warm front. Still think temperatures will warm sufficiently tonight to keep freezing precipitation isolated and brief at best, confined to the fringe of cold air damming region east of the slopes. The warm front is projected to surge north of the region on Monday morning as the parent low digs over Eastern Canada. Precip is thus forecast to end until the approach of the systems cold front late in the day. Have increased PoPs to categorical numbers with the evening/overnight cold front, and used tweaked RFC guidance for QPF, which maintains rainfall in the quarter to half inch range.
700 PM EST Sun Dec 25 2016 High pressure will ridge into the forecast area from the north through Monday night. A warm front will develop just south of the region tonight.
The cold upper low will continue to move off to the east tonight.
Highs on Monday will climb into the lower 60s as cloudy skies prevail over much of the area.
Energy to our north will also push a weak and dry cold front south through Texas Panhandle Monday morning and afternoon but will struggle to have any influence on even our northern counties. Could see some low clouds and or patchy fog early tomorrow morning across our southwest counties as RHs increase on northern periphery of surface ridging to our south per HRRR, though GFS and ECMWF not showing that level of moisture.
With the low pressure system remaining to our east, there will be a sharp cutoff in snowfall accumulations with this storm. as the low pressure system tracks to the northeast, a tight pressure gradient will develop leading to gusty winds that will likely lead to whiteout or near whiteout conditions this evening and overnight.
Across the rest of the forecast area, winds have subsided considerably as a large cyclone lifts rapidly northeast away from the area into the northern Plains.
542 PM CST Sun Dec 25 2016 We have seen quite the transition in weather across the Missouri Ozarks over the last 12 hours as a warm front continues to lift northeast across the area. A trailing surface front/trough will be the focus of a thin line of showers and a few isolated thunderstorms this evening and overnight as this feature tracks east across the area. We have gone on the high side of guidance with highs expected to reach the lower to middle 60s over most areas.
chance for any significant cold air intrusions into the lower 48 are slim at best.
204 PM PST Sun Dec 25 2016 A low pressure system will pass to the west, brushing the Central coast late tonight into Monday morning possibly bringing light rain to the area.
/issued 232 PM CST Sun Dec 25 2016/ An upper low currently over the central Rockies will continue to move northeast tonight into the northern Plains.
Best times for the lower conditions look to be between 10-15Z Monday. The latest MAV/MET and ECS temp guidance for the region is in decent agreement with the ECMWF showing a slight warmer bias versus the NAM and the GFS. Will lean closer to the warmer side of guidance through tomorrow. The numerical guidance maintain some slgt chc pops through Mon as a cold front sweeps through central Texas tomorrow.
634 PM EST Sun Dec 25 2016 Temperatures will surge warmer late tonight as a warm front lifts through bringing a period of dense fog to the region. A cold front will then cross the area Monday with showers expected.
213 PM PST Sun Dec 25 2016 A low pressure system will pass to the west, brushing the Central coast late tonight into Monday morning possibly bringing light rain to the area.
642 PM EST Sun Dec 25 2016 A warm front will bring a chance for light rain tonight and early Monday. A better chance arrives with a Monday night cold front. This is especially true west of the ridges, ahead of the advancing warm front. Still think temperatures will warm sufficiently tonight to keep freezing precipitation isolated and brief at best, confined to the fringe of cold air damming region east of the slopes. The warm front is projected to surge north of the region on Monday morning as the parent low digs over Eastern Canada. Precip is thus forecast to end until the approach of the systems cold front late in the day. Have increased PoPs to categorical numbers with the evening/overnight cold front, and used tweaked RFC guidance for QPF, which maintains rainfall in the quarter to half inch range.
Not as cold as previous nights but with strong radiational cooling and decoupling in the lower layers should be enough to drop areas into the upper 30s in very open areas and into the lower 40s in the more urbanized areas.
1152 PM CDT Sun Mar 19 2017 Southerly winds thru period as low pressure develops southern plains. Otherwise, temps to fall into the lower 60s tonight.
1052 PM EDT Sun Mar 19 2017 High pressure building eastward from the Great Lakes into the North Country will remain the dominant weather feature across the area through Monday.
A slow moving cold front will then move across srn WI for Mon AM. Rain chances will continue near the IL border through Mon AM with the passage of the cold front. Mid level ridging dominates here for much of the night though the sfc/850 trough axis will swing through later tonight. A mild night with a sustained southerly wind ahead of the trough. Medium Looks like there may be a little better phasing of the arrival of mid level vort max with the lower level forcing across SE WI.
Temperatures are in the upper 60s and low 70s across the island chain, with dew points in the low to mid 60s. Expect another cool night, with pleasant temperatures sinking to the low to mid 60s.
841 PM EDT Sun Mar 19 2017 High pressure builds over the area into Monday, before weak low pressure crosses the area Monday night.
750 PM EDT Sun Mar 19 2017 High pressure building eastward from the Great Lakes into the North Country this afternoon will remain the dominant weather feature across the area through Monday.
Forecast on track this evening as calm and quiet weather is in place thanks to high pressure. For now, will continue with the previously issued SPS for brief freezing conditions possible across far Northeast TN and Southwest VA. Chattanooga Airport, TN 39 70 55 76 / 10 0 20 40 Knoxville McGhee Tyson Airport, TN 36 67 53 72 / 0 10 30 50 Oak Ridge, TN 36 67 53 72 / 0 10 30 60 Tri Cities Airport, TN 31 65 49 66 / 0 10 40 60.
1039 PM EDT Sun Mar 19 2017 As low pressure moves further offshore. high pressure will move east across the area tonight.
729 PM EDT Sun Mar 19 2017 High pressure along with cooler and drier air will remain over the region through Monday night.
/issued 310 PM CDT Sun Mar 19 2017/ A weak cold front has become nearly stationary across the P/CWA today, bisecting the forecast area in a NNW to SSE orientation. Considerably drier air has filtered into the eastern sections of the area behind this front with dew points in the 40s compared with dew points in the low to mid 60s across western zones.
/issued 302 PM CDT Sun Mar 19 2017/ Hot temperatures will persist into Monday as an upper level ridge with anomalously high heights will remain overhead. Thicknesses are progged to increase the next 24 hours and with a warm overnight period expected, highs tomorrow should push 2-4 degrees warmer than those of today in line with MOS values. Winds should be less than 15 mph through the day with the possible exception of the southern Rolling Plains, the part of the area farthest from the trough, but there winds should be mainly from the south to southwest.
Latest observations and satellite imagery show the cold front currently extending from Miami Dade and Inland Monroe County. Temperatures will lower into the low to mid 50s west and interior and into the low 60s along the east coast metro areas. Current satellite and observations show the cold front close to Lake Okechobee with a north to northwest winds gusting between 15 to 20 mph and a cloud deck at around 3000 feet ahead of it. Dry air will continue to advect into the region early portion of the week, allowing to lower rh values into the upper low 40s upper 30s and mid to low 30s by mid week.
Coastal areas will see a greater range in temperatures with communities along I-95 several degrees cooler than their barrier island counterparts. As high pressure builds in behind the front Monday, winds will decrease to 10-15 knots out of the northeast with seas slowly subsiding, but remaining up to 6-7 feet over the gulf stream. High pressure building in behind the front will lead to lighter northeast winds around 10 mph in the afternoon.
753 PM EDT Sun Mar 19 2017 High pressure tonight. Warm front late Monday followed by a cold front Monday night.
High pressure aloft with low level offshore flow will persist through Monday morning. Southerly flow aloft will strengthen Monday afternoon, opening the door to a series of low pressure systems from the south that will impact the area through midweek. These clouds are associated with a low pressure system currently off the CA coast. After the upper ridge axis exits to our east late tonight, flow aloft will back from westerly to southwesterly on Monday.
While the SFC/low level ridge has shifted a little to the east today, conditions appear ripe once again for radiational fog formation later tonight. High pressure will remain in control of the regional weather pattern through most of the week.
1201 AM EDT Mon Mar 20 2017 Low pressure will track well south of the region overnight. High pressure will build across the region Monday.
1045 PM EDT Sun Mar 19 2017 As low pressure moves further offshore. high pressure will move east across the area tonight.
830 PM EDT Sun Mar 19 2017 Dru cold front has exited the region with breezy northwesterly winds bringing some cooler and much drier air into the area. For the rest of tonight winds will diminish and shift to northeast under clear skies with temperatures falling into the lower 40s north to mid 50s near the coast from around Tampa Bay southward. On Monday high pressure will settle over the region with mainly sunny skies expected.
Otherwise, temps to fall into the lower 60s tonight. /issued 724 PM CDT Sun Mar 19 2017/ Low pressure over southern plains allowing for south winds at sfc at least 5 kts across much of area overnight.
731 PM EDT Sun Mar 19 2017 As low pressure moves further offshore. high pressure will move east across the area tonight.
917 PM EDT Sun Mar 19 2017 Low pressure will track well south of the region overnight. High pressure will build across the region Monday.
High temperatures will be fairly similar to Sunday's across the north and just a bit cooler across the south.
758 PM EDT Sun Mar 19 2017 High pressure building eastward from the Great Lakes into the North Country will remain the dominant weather feature across the area through Monday.
849 PM EDT Sun Mar 19 2017 Only adjustments were to hourly temperatures as real world is a few degrees warmer than forecast. Tranquil conditions overnight with lows falling into the low to mid 40s. Expect lows overnight to fall into the low to mid 40s region wide as a result.
/ISSUED 239 PM CDT Sun Mar 19 2017/ High pressure will continue over SE Texas through mid week. This is reflected in the high resolution models showing lower chances for fog formation than 24 hours ago. The main impacts of the high pressure ridging will be dry and warm conditions.
The ridge will then move east of our area tonight. A cold front will push southeast across the Great Lakes and Ohio Valley Monday into Monday night, bringing showers and a few embedded thunderstorms.
731 PM EDT Sun Mar 19 2017 Aviation A cold front will move across the state Monday triggering some light rain and perhaps a thunderstorms south of I-95.
1029 PM EDT Sun Mar 19 2017 Update A cold front will move across the state Monday triggering some light rain and perhaps a thunderstorms south of I-95.
1115 PM EDT Sun Mar 19 2017 As low pressure moves further offshore. high pressure will move east across the area tonight.
517 PM MDT Sun Mar 19 2017 20z surface analysis had cold front from eastern ND to the Black Hills into northwest WY. Cold front will stall just south of the CWA.
840 PM EDT Sun Mar 19 2017 A cold front will bring the next chance of rain later on Monday.
818 PM EDT Sun Mar 19 2017 It will be a quiet and dry evening as high pressure slides to our east. There is a chance for showers and a few thunderstorms overnight with the highest chances over northwest Indiana. A cold front will cross the area Monday and widespread showers and scattered thunderstorms are expected.
719 PM EDT Sun Mar 19 2017 High pressure builds into the region tonight and Monday. Warmer and dry weather can be expected Monday, with temperatures trying to get above 40 for the first time in a while in many places.
1051 PM EDT Sun Mar 19 2017 High pressure tonight. Warm front late Monday followed by a cold front Monday night.
Model forecast soundings indicate that as system arrives, it will take time for the low levels to saturate and once the low levels begin to saturate, moisture decreases in the dendritic zone. Amounts within the snow band could reach a half inch to near an inch given the high liquid to snow ratios with the cold temps, while locations outside the band see little if any snow accumulation.
Generally MVFR conditions are expected to persist through the day as a cold front pushes through the area. A cold front will move through S TX today bringing cooler temps in its wake. Latest model solns are cooler and a tad stronger with this front than previous runs. Based on MSAS analysis/trends and the high pressure rises, feel the faster/stronger/cooler soln is more likely. Cloudy cooler conditions are expected tonight,then isentropic upglide will increase through Fri leading to a cool wet day.
A weakening short wave trof is moving into the Great Basin this morning with considerable mid and high level moisture streaming into UT out ahead of this wave. A shallow cold layer remains in place in the lowest elevations across the west deserts as well as in the Cache valley and this will likely not mix out today. So type of precip if any reaches the ground is still uncertain in the areas with shallow cold air between snow and freezing rain. Uncertainty about P-type will once again be a factor as some of the lowest areas could still have a shallow cold layer in place and a threat of freezing rain, otherwise precip should fall as rain below about 6000 ft.
311 PM CST Thu Feb 2 2017 A cooler air mass has spread into the area today as afternoon temperatures are currently in the 30s. Southerly winds will start to return from west to east Friday night as the high starts to move off to the east.
1219 PM EST Thu Feb 2 2017 Cooler than average temperatures will carry into the weekend.
The forecast remains on track with cooler conditions today through the weekend. /issued 648 AM CST Thu Feb 2 2017/ A cold front movg into ne TX bringing wshft to KTYR attm, and about to move into KGGG. /issued 631 AM CST Thu Feb 2 2017/ This morning the cold front continued to move South into the Four State Area as was roughly along the Louisiana/Arkansas border and into Northeast Texas West of Texarkana and to near Idabel Oklahoma, and then draped South to Tyler and College Station Texas. This boundary was shallow and the shape shows the higher terrain of Southeast Oklahoma and Southwest Arkansas blocking the transport of the colder air into the area. Cloud cover looks to hold over the area even with high pressure in control due moisture above the surface remaining around.
The cold front was near this corridor as it was moving slowly to the south. Temperatures will continue to fall from the north in the wake of the cold front.
318 PM CST Thu Feb 2 2017 Much cooler day across North Texas today as the cold front has pushed into south/southeast Texas. though temps will be a bit warmer and winds will be lighter than today. As with the majority of the cold front passages this winter. the cooler air will not stick around for long as zonal flow continues into the weekend.
1207 PM CST Thu Feb 2 2017 A cold front has pushed south of the region, leaving northerly winds and cooler temperatures in it's wake. A cooler airmass will spread across the area as northerly winds dominate with highs near climate normals with lower 60s over the Hill Country and mid 60s along the I-35 corridor. Clouds return tonight across most areas as a shallow cooler airmass remains near the surface and isentropic upglide takes control above that layer. Cooler temps are also expected with highs in the mid 50s to lower 60s.
Isolated to widely scattered showers are occurring across the region along and ahead of a cold front. /issued 326 AM CST Thu Feb 2 2017/ A cold front is located this early morning from roughly the Arklatex to South Central Texas. Rua The cold front will continue to move eastward today, reaching the forecast area this afternoon, and out into the coastal waters this evening. Some drier and cooler air, with a brief period of northerly winds, will occur on Friday, behind the front.
The cold front will then accelerate southward Friday afternoon as an upper trough passes by to the northeast.
The clouds in the south may keep temps a bit warmer there. We may see some occasionally gusty winds mix down to the surface overnight as the pressure gradient in the low levels remains fairly tight, especially in our northeast. Wind chills will be quite cold, but 10-20 degrees warmer than Wind Chill Advisory criteria. Weak WAA will kick in around 18z Friday as ridging/high pressure push into the area.
/issued 909 AM EST Thu Feb 2 2017/ The high pressure over Florida has shifted slightly northward which has resulted in a slight backing of the winds to the east-northeast. With this high pressure, you can expect continued sunny skies and warm above average temperatures for west central and southwest Florida today. High pressure ridging across northern Florida will produce a predominant east-northeast flow across the coastal waters today.
334 PM CST Thu Feb 2 2017 Dry weather is expected through tomorrow as high pressure currently over the northern Plains moves southeastward into Missouri and Illinois by Friday afternoon.
300 PM EST Thu Feb 02 2017 High pressure will build over region today and tonight. A weak wave of low pressure is expected to affect the coastal Carolinas later tonight and early Friday.
High pressure ridge extending across Florida will gradually weaken into tomorrow as a cold front approaches north Florida. Lows tonight will range from the low to mid 50s over much of the area, with highs in the upper 70s to around 80 degrees Friday.
Models are in general agreement with weak system moving across Nebraska with broad zone of geographically driven lift over the High Plains gradually weakening before it reaches much further east as high pressure moves into the state late tonight. Meanwhile a subtle cold front is progressing southeast across western Wisconsin to southern Minnesota at 20z. Conservatively temperatures should warm into the lower to upper 30s both Sat/Sun with coolest readings over the north.
/issued 950 AM CST Thu Feb 2 2017/ The lower clouds in parts of the fa are expected to spread west some this morning. An even cooler day is expected today compared to yesterday with highs in the 30s and 40s.
A weak mid-level trough will drop southeast through the region overnight, but appears no more than a few high/mid-level clouds will result.
Cold front is situated across central Mississippi and central Louisiana near Alexandria and should steady nudge southward overnight. Temperatures tomorrow will be running about 15 to 20 degrees cooler than this afternoon's readings along with low cloudiness and gusty northwesterly winds.
223 PM CST Thu Feb 2 2017 A cold front will continue to move south of the Ark-La-Tex area this evening. Expect cloudy and cool conditions through the weekend with the high pressure moving to the east of the area.
This should keep lows on the higher side of guidance.
155 PM PST Thu Feb 2 2017 Clouds will gradually increase leading to some light showers Friday through Friday night as a trough moves by to the north, skimming Southern California.
A broad trof extended acrs the Nrn USA with a ridge over the Desert SW. This trof will move thru the ridge into UT/WY today and then rapidly cross the fcst area tonight. The Wrn ridge will pop back up in its wake. The cold front that moved thru Mon extended from NC-TX then N into CO. This high will slowly creep SE into SD/Neb tonight.
Meanwhile, nearly zonal flow prevails aloft while lower to mid level ridging remains nearby. Forecast - The ridge to our north will hold for the next couple of days. Heading into the weekend another stronger high pressure system will move into the eastern United States. However, the associated pressure gradient is largely held back to our north by a deepening inverted trough off the southeast Atlantic coast. Through the weekend, the combination of another mid latitude trough and the low level trough off of Florida will bifurcate the previously mentioned high. Thereafter, this high cell will expand eastwards with the axis settling southwards into South Florida.
