305 AM CDT Fri Oct 21 2016 Today and Tonight, an upper trough was located across the Mid MS river valley early this morning and will move east, off the mid Atlantic coast late Tonight. An upper level ridge across the southwestern US will slowly drift east into the southern high plains by late Tonight. After a cool start this morning with temperatures in the mid to upper 30s, highs Today will reach the lower to mid 60s with some upper 60 degree highs across the southwest counties. Overnight lows will only drop into the lower to mid 40s Tonight.
404 AM CDT Fri Oct 21 2016 Nice wx will be on tap for the next several days in the wake of the cold front that pushed thru the region yesterday. 47 Strong and gusty north winds in the wake of the cold front are ex- expected to continue over all the coastal waters this morning and into this afternoon for the offshore waters. No major change with the rest of the forecast as winds continue to decrease by to- night as high pressure builds into the region. Onshore winds will gradually return by Saturday night as the high shifts east of the area. 41 Mid/high clouds continuing to clear to the south this morning as the cold front moves further into the Gulf.
/ISSUED 325 PM CDT Thu Oct 20 2016/ The much anticipated cold front has cleared all of North and Central Texas today ushering in much cooler air and gusty north winds. The last of the lower cloud cover is clearing the southeast counties at this hour and clear skies are expected this evening and tonight.
203 AM MDT Fri Oct 21 2016 Early morning WV imagery and RAP analysis shows large scale ridging building across the western US into the plains, with NW flow over the Central High Plains. At the surface, high pressure has slid east of our CWa towards the southern Missouri River valley. Lee trough has redeveloped and southerly surface gradient is in place over our CWA. There is still enough time for winds to drop off and temps to quickly fall to the lower 30s across our entire CWA due to mostly clear skies and Tds in the 20s to lower 30s.
150 AM EDT Fri Oct 21 2016 Low pressure will track across southern and eastern Ohio this evening along a frontal boundary. The low will reach central pennsylvania to central New York State tonight. As the low passes it will pull a strong cold front eastward with it. Much cooler air will spill across Northern Ohio and Northwestern Pennsylvania Friday into Saturday which will cause lake effect showers across the snowbelt. Friday the upper trough axis will be over the area.
313 AM CDT Fri Oct 21 2016 Not much going today other than the high clouds and the warming temperatures. Highs will be warmer today than yesterday despite the high level clouds. Upper the highs a littlee in southwest Minnesota due to favorable downsloping winds off the Buffalo Ridge which will add a few degrees to the temps. Then the surface winds will begin to veer to the northwest Saturday night behind a very weak cold front, ushered through by a mid level short wave maximized near 700mb passing across the Dakotas and Minnesota.
Surface cold front roughly lies from KCTJ-KMOB at 06Z and moving eastward. The 7 pm regional surface analysis showed a cold front, rather strong in terms of temperature contrast, from northeast AL through coastal TX. The cooler air will lag behind the front such that there won't be a significant cool-down until Friday. The dry cold front will have cross the entire Tri-State region by early Friday afternoon. This will allow a relatively sharp temperature gradient to develop across the region with mid 80s in the southeast Big Bend, and upper 70s across Alabama where diurnal mixing taps into the cooler air aloft. The cooler air aloft will cover much of the local area on Saturday, resulting in highs in the low to mid 70s area-wide. Expect lows to fall into the low to mid 40s across all inland areas.
425 AM EDT Fri Oct 21 2016 Rain event persists over the North Country as a mid-level longwave trough continues to dig south and east from Canada.
With a dry atmospheric column and and building high pressure aloft, skies should be mostly sunny. Saturday will be another fine looking day, starting off chilly in the morning (40s/low 50s) but ending a couple degrees warmer across the board, with mid 70s in the Hill Country to low 80s towards the Coastal Plains.
Otherwise the remainder of Friday and Saturday will be dry and cooler with daytime highs only in the low to mid 50s.
1028 PM PDT Thu Oct 20 2016 Rain will taper off but still linger over Southeastern Washington and the lower Idaho Panhandle on Friday.
315 AM PDT Fri Oct 21 2016 High pressure aloft will weaken today with much weaker offshore flow.
Rain will begin to increase in coverage this afternoon, but the highest chances are forecast to be tonight for north central Idaho and northwest/west central Montana.
1122 PM MDT Thu Oct 20 2016 Dry weather will continue across southeast and south central CO tonight and Friday as an upper level ridge builds over the area. Tonight there will again be some areas of temps around freezing or in the upper 20s. Portions of the far southeast plains should see low temps in the lower 30s and they could see some areas of frost, but not expecting a long period of freezing temps so will not issue a highlight, but will mention some frost in the forecast. On Friday, temps will be warmer and should be about 10 degrees above average over the southeast plains, with about 5 degrees above average in the San Luis Valley.
Steady expansion of high amplitude troughing into the region today. Limited insolation potential given the extensive cloud cover will contribute to a notably cooler day, as will a firm and intermittently gusty north wind. Upper trough axis exits to the east tonight, with a backing low level flow eventually pivoting the Lake Huron moisture plume largely offshore. With that said, some perpetuation of the existing stratus may continue well into the night given the existing low level thermal troughing. In addition, surface ridging is displaced too far to the west to yield a more favorable light wind field. Thus, continue to favor a low temperature distribution that leans on the warmer side of the model guidance spectrum. Temperatures a touch warmer relative to Friday, with highs 50 to 55.
Dry with ridge of high pressure aloft building over NM from the west and sfc lee trof. Upper level ridging will dominate the weather pattern today before the ridge shifts eastward over the weekend.
1140 PM MDT THU OCT 20 2016 06Z TAF CYCLE A strong high pressure system will move over the SW US from the W for the remainder of tonight and Friday with little if any cloud cover and generally light winds. Also, a lee trough on the eastern plains will induce some gusty winds on Friday. Cooler temperatures were short lived today but they will rebound quickly Friday into the weekend to above normal readings areawide as the dry, upper level ridge shifts eastward.
426 AM EDT Fri Oct 21 2016 Low pressure is well east of the region this morning as we await the passage of the upper level trough. As this trough passes it will allow much cooler air to spill into the area.
324 AM MDT Fri Oct 21 2016 A large upper ridge will move east across the area, with its axis passing overhead this evening. Warmer temperatures, clear skies and dry weather will result across the forecast area. Dry air between 750 and 550 mb, as evidenced by the soundings from KGJT and KDEN has produced humidities in the teens across the higher mountains. Even though skies are expected to be clear tonight, the upper ridge and surface lee trough will produce minimum temperatures 10 to 15 degrees warmer than climatologically normal, especially east of the divide and over the plains.
326 AM EDT Fri Oct 21 2016 Low pressure and its associated cold front exit east of the mountains through this morning.
A cold front will track across the Southern Appalachian Region this TAF period.
A cold front will track across the Southern Appalachian Region this morning. the main concern will be much cooler air moving in behind the front. The low clouds are expected to hang around for much of the day. expect a cooler night than we have seen recently as temperatures fall into the lower to mid 40s across most valley locations.
149 AM CDT Fri Oct 21 2016 Cold front has entirely passed through Middle Tennessee with still a few light radar echoes showing up over the Cumberland Plateau. A brisk northerly flow is advecting cooler, drier air into Middle Tennessee with the clearing line now reaching into far western TN/KY. Can't completely rule out a few places getting some frost, but won't include this in the grids just yet as dew points will remain several degrees above freezing. High pressure will build to our south over the weekend, with return flow by Saturday or Saturday night.
A cold front remain just northwest of the region today and will be the focus for precipitation tonight across our northern zones. A weak upper level trough moves inland late tonight which shifts the cold front southwest over Burns, Baker city and McCall. Embedded convective showers could produce higher rainfall amounts so the Cornet-Windy ridge burn scar will need to be monitored. The band dissipates late Saturday morning as the trough exits the region and the upper level ridge rebuilds northward.
1104 PM MDT Thu Oct 20 2016 Upper level analysis has trof shifting east into the Great Lakes region, and ridge building across the Northern Rockies. At the surface, high pressure resides across the eastern Dakotas, with lee trof strengthening across central MT and eastern WY. Eastern pac troughing will persist through the period as fast westerly disturbed flow over the northern pac supports trough re- loading there. This will continue to support downstream mean ridging. Flow will remain progressive with periodic disturbances ejecting out of the persistent trough. The determining factors will be timing of the trough and mixing heights.
325 AM CDT FRI OCT 21 2016 Cold front is now pushed well into the gulf with good cold air advection continuing across the forecast area this morning. Through the weekend pattern will be influenced by progressive trough going through the eastern U. followed by a low amplitude ridge.
Early morning water vapor imagery has shown a sharp short wave moving across the northern Rockies and into the high plains of Montana. A stronger downslope wind along the lee of the Buffalo Ridge may allow for higher temperatures than expected. The current forecast has low 60s east of this ridge, but I would not be surprised to see a few mid/upper 60s if the right downslope component develops. A mild and dry weekend is still in the works, as high pressure ridging dominates the north central CONUS between troughs on both coasts. Conditions deteriorate early in the upcoming week as energy from the west coast trough spills into the Plains. By late in the weekend, energy from the western trough starts to push into the Central Plains.
419 AM EDT Fri Oct 21 2016 A crossing cold front and large upper level system, will generate more rain today. Much cooler weather will follow for the weekend. Behind the exiting front, strong cold air advection will ensue, and the main upper level trough axis will move over my Ohio counties early this afternoon. The trough axis will pass to the east of the area late this evening, and the colder air will continue to advect in. Cold advection in northwest flow, will keep in shower chances Saturday, but this too will drift eastward as the large upper level low swings northeastward toward New England. Locations in the ridge counties, especially on the peaks, could see a few snow showers mix in Saturday morning. Building high pressure will bring and end to any lingering showers over the northeast Saturday evening.
356 AM CDT Fri Oct 21 2016 A strong cold front that entered the forecast area yesterday has pushed through, just now passing the mouth of the Mississippi River. Highs today will generally be in the lower to mid 70s.
354 AM EDT Fri Oct 21 2016 Low pressure and its associated cold front exit east of the mountains through this morning.
347 AM CDT Fri Oct 21 2016 500mb ridge will be overhead through Saturday. The warm up begins today, with highs around 10F warmer than yesterday.
533 AM EDT Fri Oct 21 2016 A crossing cold front and large upper level system, will generate more rain today. Much cooler weather will follow for the weekend. Behind the exiting front, strong cold air advection will ensue, and the main upper level trough axis will move over my Ohio counties early this afternoon. The trough axis will pass to the east of the area late this evening, and the colder air will continue to advect in. Cold advection in northwest flow, will keep in shower chances Saturday, but this too will drift eastward as the large upper level low swings northeastward toward New England. Locations in the ridge counties, especially on the peaks, could see a few snow showers mix in Saturday morning. Building high pressure will bring and end to any lingering showers over the northeast Saturday evening.
A large Upper level trough axis will reach the eastern Great Lakes this evening as a ridge pushes into the Northern Plains.
223 AM CDT Fri Oct 21 2016 An upper level ridge of high pressure centered over Arizona will move east across the southern states through the weekend promising above normal temperatures and no precipitation.
The associated cold front will move slowly across the state tonight and Friday.
Dry conditions will persist across the Western High Plains today as short range models show upper level ridging shifting slowly east across the Desert Southwest into the South Plains. A weakening flow aloft and a lack of moisture in the low/mid levels will contribute to a dry forecast across western Kansas through Friday night. Warmer temperatures are likely today as prevailing southerlies across western Kansas help draw warmer air northward into the state. Temperatures will remain well above freezing Friday night with lows generally in the 40s(F). Highs will rise into the low 80s for the weekend as a strong upper ridge develops across the mid section of the country. Winds will turn more southerly while increasing 15 to 25kt late Friday morning as a developing lee side trough of low pressure strengthens across eastern Colorado during the day.
351 AM CDT Fri Oct 21 2016 Ridge to the west continues to build east into the northern plains today with warmer temperatures aloft. Dry air in place with light winds will promote rapid cooling tonight across the region, with lows falling to near the freezing mark in favored lower spots. A warm day Saturday with a thermal and upper level ridge across the region.
The associated cold front will move slowly across the state tonight and Friday. Highs will range from the lower 50s northwest to the mid to upper 70s southeast. A cool and unsettled day is in store Saturday as persistent northwest flow and progressively cooler boundary layer air is forced into the region. and we'll certainly be looking at a few flurries mixing in with any shower spritzes in the afternoon and evening over the higher terrain of the northwest and northern mountains. Maxes will range from the lower 40s northwest to the lower to middle 50s southeast.
High pressure will reside across the region today.
1151 PM MDT Thu Oct 20 2016 High pressure will filter warm, dry air into the region over the next couple of days. Near freezing temperatures will again be a concern tonight for many valleys. However, freezing conditions do not look to be widespread enough to warrant any highlights. Dry weather will persist for the weekend as high pressure remains in control.
High pressure will bring quiet weather with dry conditions to northern and central Nevada through the weekend. Under a ridge of high pressure, a quiet weather regime is upon us. A few high clouds outline the axis of the ridge crest. The center of high pressure will move from the southern California and western Arizona today to reposition near the Texas/Gulf coast by Saturday. Ridging will sustain over much of the west bringing continued dry conditions, however the flow aloft will back towards the southwest, thus helping to boost temperatures a bit. Some afternoon gusty winds are possible with the a slight tightening of the pressure gradient on the back side of the ridge.
338 AM MDT Fri Oct 21 2016 A flat ridge of high pressure over the Mountain West will continue to bring sunny skies to the region today. Strong solar insolation will efficiently warm dry soils which then readily transfer that heat to the lower atmosphere. This process will bring slightly warmer than normal conditions to the area during the afternoon. Dry weather will persist for the weekend as high pressure remains in control.
With very light winds and clearing skies, have lowered temperatures towards the MET guidance, with subfreezing temperature possible. Temperatures however will warmer than today, with middle 60s expected in central SD, with the upper 50s further east towards Southwest Minnesota and Northwest Iowa. Weak ridge builds into the region Friday night into Saturday morning resulting in light winds and good radiative conditions. Cold front is expected to move through the region Saturday night.
Southerly winds will pickup a bit more on Saturday with highs near normal in the low 60s far east to around 70 over central Missouri. A dry fropa is expected on Sun with cooler temps on Mon. With good agreement in timing and thermal profile ahead of the fnt, raised temps for Sun twd the warmer guidance. Northwest winds will become light/variable after a high pressure center moves overhead.
317 AM PDT Fri Oct 21 2016 Mild conditions are expected Friday and Saturday under high pressure.
The high pressure center will translate east this evening/overnight and cause the wind to turn to the south/southeast at speeds generally less than 8 knots. Continued weak cold air advection should hold temperatures mostly in the low to mid 70s area-wide this afternoon.
High pressure ridging will build across the northern Rockies today resulting in rising heights and mild temperatures. Afternoon temperatures will be in the lower 60s west and central with middle 60s to near 70 degrees across the southeast. For Saturday, high pressure ridging gets flattened somewhat as a disturbance moves across the northern half of the state. This will sweep a Pacific cold front across the area late morning/early afternoon ushering in gusty northwest winds. Temperatures Saturday will be slightly cooler but still above normal for this time of year.
North winds around 5 knots this morning will back to the northwest and increase to around 10 knots after 15Z, then increase to 10 to 15 knots with gusts up to 20 knots after 18Z as a cold front moves south through the region. Winds will remain light overnight but then pick up out of the northwest through Friday as a cold front moves through the state, ushering in very nice weather for the weekend. A cold front will move through the waters on Friday with increasing northwest winds close to advisory levels late Friday into Saturday.
340 AM CDT Fri Oct 21 2016 Stratus clouds that have been shrouding many area east of the MS River overnight will gradually push east with H50 trof this morning, leaving most areas of western KY/sw IN with plenty of sunshine by noon. However, chilly high pressure nudging eat into the MS River Valley will keep temperatures in the upper 50s to lower 60s despite the return to sunshine. In fact, will not rule out patchy frost later tonight as winds slacken underneath the high pressure system and skies remain clear. High pressure will begin to push a little farther south over the weekend, allowing winds to turn swly and a warming trend to commence.
The next couple days will see an upper ridge slip east across the region with just some high clouds spilling over the area. Weak impulses moving over the northern Rockys will induce some lee troffing which will create some gusty winds around the southeast Wy mtns mainly in the afternoons.
Looks the dry airmass in place has won the battle with most of the showers dissipated along and ahead of the cold front. Only a few isolated showers will remain possible right ahead of the cold front now as it moves through the area this evening and overnight. Cold front is currently pushing through Central Alabama, with MVFR cigs behind the front affecting northern terminals already early this morning. 56/GDG Much cooler and drier conditions for Friday.
632 AM EDT Fri Oct 21 2016 Low pressure and its associated cold front exit east of the mountains through this morning.
107 AM CDT FRI OCT 21 2016 Drier and cooler air continues to filter into the state behind the cold front that pushed south through the state earlier. (ISSUED 559 PM CDT THU OCT 20 2016 ) Drier and cooler air continues to filter into the state behind the cold front that pushed south through the state today. Tonight Through Saturday 20z subjective surface analysis indicates the cold front is now on the southeast border of the forecast area.
Continued weak cold air advection should hold temperatures mostly in the low to mid 70s area-wide this afternoon.
335 AM EDT FRI OCT 21 2016 Steady expansion of high amplitude troughing into the region today. Limited insolation potential given the extensive cloud cover will contribute to a notably cooler day, as will a firm and intermittently gusty north wind. Upper trough axis exits to the east tonight, with a backing low level flow eventually pivoting the Lake Huron moisture plume largely offshore. With that said, some perpetuation of the existing stratus may continue well into the night given the existing low level thermal troughing. In addition, surface ridging is displaced too far to the west to yield a more favorable light wind field. Thus, continue to favor a low temperature distribution that leans on the warmer side of the model guidance spectrum. Temperatures a touch warmer relative to Friday, with highs 50 to 55.
This afternoon through this evening, a broad ridge of high pressure will push through the region giving NE Montana a very nice and comfortable autumn day. Late tonight, the ridge over our region becomes replaced by SW flow aloft and better chances for more organized rain showers through late Saturday night. Temperatures are expected to remain above freezing. An upper ridge will be building over the northern plains through the weekend, opening the region to southwest flow aloft.
Much cooler and less windy today in wake of yesterdays strong cold frontal passage.
Snow associated with the upper trough will generally remain to our east today. The trough will be close enough for light snow showers or flurries in portions of SW Idaho, mainly in the West Central and Boise Mountains and in the Western Magic Valley. A colder air mass arriving behind the departing trough has allowed for temperatures to plummet into the single digits (above and below zero) in Harney County and Malheur County.
323 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 Monday morning for a brief period of freezing rain and a winter weather advisory has been issued for the area.
1252 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.
there is very light snow, sleet, freezing drizzle causing slippery roadways (and have issued an SPS for these conditions until the start of the warnings). Any concerns would be the slightly westward track of the low which would lead to more potential for freezing rain which could limit snow totals on the eastern edge of the snow shield from the central valley into NW Mn. Prior to the main area of pcpn moving in this afternoon freezing drizzle will likely cause travel impacts so no plans on changing start time of warning. There then could be a break in the wind during part of the overnight as the low lifts ne through the area then strong northerly winds developing towards morning bringing a return to blizzard conditions.
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.
