742 AM EDT Tue Oct 17 2017 High pressure will maintain dry weather this week along with a gradual warming trend. High pressure becomes centered south of New England, putting us in SW flow tonight and Wed. - Warmer than normal through this period - Dry weather through this weekend This portion of the forecast will feature a nearly zonal mid level flow evolving into a strong ridge toward this weekend. Almost no moisture to work within the lowest levels of the atmosphere, so mainly clear skies expected until later this weekend.
746 AM EDT Tue Oct 17 2017 Strong high pressure will bring dry weather through the remainder of the week. Synoptically quiescent conditions with clear skies and sfc anticyclone bisecting the North Country early this morning. Afternoon highs expected to range from the low 50s east of the Green Mtns, to the upr 50s in the Champlain Valley, and generally 55-60F across nrn NY.
900 AM EDT Tue Oct 17 2017 Cool and dry high pressure will build into the Mid-atlantic today. The high pressure system will moderate and persist into the first part of the weekend. A cold front will approach the region late in the weekend. Aside from some patchy thin jet streak cirrus across eastern NC, expect abundant sunshine with a steady northerly breeze of 6 to 10 kts, that will occasionally gust into the lower teens.
1005 AM EDT Tue Oct 17 2017 Dry high pressure with cool mornings and warm afternoons, with temperatures moderating through the weekend.
Temperatures will be warmer today with light winds. Lee trough sets up to our west on Wednesday with more wind.
1053 AM EDT Tue Oct 17 2017 High pressure will remain in place over New York and Pennsylvania for the remainder of the week with a gradual warming trend and dry weather expected. The cold temperatures this morning are the main focus in the near term with high pressure dominating the region through the middle of the week and beyond. Temperatures today will be roughly 5 to 15 deg warmer than yesterday.
701 AM EDT Tue Oct 17 2017 Upper level flow out of the wnw will continue through this afternoon before a trough moves through the northern plains tonight. Wednesday, ahead of an approaching cold front temperatures are expected to climb 15 to 20 degrees above normal as low-level warm air advection spreads northward across Upper Michigan.
1001 AM EDT Tue Oct 17 2017 Morning water vapor imagery and upper air analysis shows ridging extending northward into the southwest U. with broad troughing over the east. At the surface, a cold front is still slowly dropping southward across the northern peninsula with high pressure, along with cooler and drier air, building in behind it over the southeast. For the rest of today, the cold front will continue to try and drop southeastward, but will lose momentum as the main trough continues to lift out. High pressure will build over the southeast through the rest of the day and tonight, with northeast winds increasing near advisory level across the rest of the forecast waters.
1134 AM EDT Tue Oct 17 2017 A broad area of high pressure builds in from the west today. The high will remain in control through the weekend. At the surface, high pressure to the west gradually builds to the south of the region. By the afternoon winds go variable to a light WSW direction with high pressure starting to settle on top of the region. Good radiational cooling conditions likely tonight across interior with a favorable waa aloft setup for decoupling; allowing temps to fall into the lower to mid 30s once again. Sunny skies and a gradual moderation in temps begins on Wednesday as SW return flow develops around the high to the south. Ridging both aloft and at the surface prevails through much of the period.
Strong high pressure ridging prevails over the area today along with a very dry airmass. /15/ Prior discussion below: Today and Tonight: Continued cooler than normal and dry. Under a light wind and full insolation today, temperatures will top out several degrees warmer than yesterday but still a couple degrees cooler than normal. Under clear skies and a near calm wind tonight, strong radiational cooling of our dry airmass will lead to morning lows cooler than normal again. Lows will range from the lower 40s east to the upper 40s south and west. Normal lows run in the lower 50s.
/issued 357 AM CDT Tue Oct 17 2017/ A modest warming trend will carry through the remainder of this week ahead of our next major cold front set to arrive later on this weekend. In the meantime, expect the upper longwave pattern to become more progressive as the trough which brought our most recent cold front exits the eastern seaboard later today. Upper ridging will become more amplified across the mid-section of the country by mid to late week with the aforementioned warming trend getting a boost. This will push high temperatures back near 80 degrees in our northern zones and ranging through the lower 80s farther south by Wednesday.
/22/ Today and Tonight: Continued cooler than normal and dry. Under a light wind and full insolation today, temperatures will top out several degrees warmer than yesterday but still a couple degrees cooler than normal. Under clear skies and a near calm wind tonight, strong radiational cooling of our dry airmass will lead to morning lows cooler than normal again. Lows will range from the lower 40s east to the upper 40s south and west. Normal lows run in the lower 50s.
800 AM EDT Tue Oct 17 2017 A weak cold front is slowly approaching the area. /issued 327 AM EDT Tue Oct 17 2017/ SHORT TERM (TODAY THROUGH WEDNESDAY): An upper level trough over the southeast US is associated with a surface cold front boundary moving through northern Florida. The cold front will move into South Florida later tonight before stalling and washing out across the region Wednesday. Even though this is a cold front we will not see any significant cooler air as temperatures will remain around normal.
1040 AM EDT Tue Oct 17 2017 High pressure centered over the Ohio Valley will bring mostly sunny skies to the region today. The high will shift south of our region tonight and stall over the Mid-Atlantic coastline through the end of the week.
A dry atmosphere and some lower level ridging should keep flight weather vfr through almost the entire forecast period.
856 AM EDT Tue Oct 17 2017 A cold front is sliding southeastward across the northern Florida Peninsula at this hour. The is weakening over the Gulf of Mexico due to upper level support is removed, and the warmer waters of the Gulf are modifying the air mass. This ridge will steepen the pressure gradient acorss the Keys area, but the ridge may not influence the winds over the Keys as much as previous model runs. As the ridge builds in rain chances will settle back into the low end chance of showers, and slight chance of thunderstorms.
1043 AM EDT Tue Oct 17 2017 High pressure remains across the eastern Tennessee Valley.
1029 AM EDT Tue Oct 17 2017 A broad area of high pressure builds in from the west today. The high will remain in control through the weekend. At the surface, high pressure to the west gradually builds to the south of the region. By the afternoon winds go variable to a light WSW direction with high pressure starting to settle on top of the region. Good radiational cooling conditions likely tonight across interior with a favorable waa aloft setup for decoupling; allowing temps to fall into the lower to mid 30s once again. Sunny skies and a gradual moderation in temps begins on Wednesday as SW return flow develops around the high to the south. Ridging both aloft and at the surface prevails through much of the period.
955 AM EDT Tue Oct 17 2017 A weak cold front is still making its way towards South Florida. /issued 800 AM EDT Tue Oct 17 2017/ A weak cold front is slowly approaching the area. /issued 327 AM EDT Tue Oct 17 2017/ SHORT TERM (TODAY THROUGH WEDNESDAY): An upper level trough over the southeast US is associated with a surface cold front boundary moving through northern Florida. The cold front will move into South Florida later tonight before stalling and washing out across the region Wednesday. Even though this is a cold front we will not see any significant cooler air as temperatures will remain around normal.
930 AM EDT Tue Oct 17 2017 High pressure will maintain dry weather this week along with a gradual warming trend. High pressure in control with sunshine and light winds, diminishing on the Cape/Islands. High pressure becomes centered south of New England, putting us in SW flow tonight and Wed. - Warmer than normal through this period - Dry weather through this weekend This portion of the forecast will feature a nearly zonal mid level flow evolving into a strong ridge toward this weekend. Almost no moisture to work within the lowest levels of the atmosphere, so mainly clear skies expected until later this weekend.
A broad trough aloft is progressing eastward toward the ern Gulf of Mexico with the mid level trough at 500 mbs moving south across AL/GA. As the frontal boundary slips south this afternoon low level NE winds will gradually strengthen across much of the area into this evening leading to low level convergence near the east coast with the highest rain chances expected across coastal Volusia and nrn Brevard where Atlantic showers will continue to stream onshore. The approaching mid/upper level trough will cool temps aloft into the afternoon and with morning sun across the south should see enough instability to continue low lightning storm chances across the area.
Just like this morning, conditions will be on the low end but still meeting criteria for both speed shear and directional shear.
1048 AM MDT Tue Oct 17 2017 Upper flow over the northern plains is west-northwesterly, as the broad ridge continues to expand over the CONUS. Under clear skies, winds are light and southwesterly, and temperatures at 2 AM range from the upper 30s to the lower 50s. Tonight, a Canadian wave will flatten the upper ridge and push a cold front into the northern plains. The upper ridge will rebuild for the end of the week, with continued dry weather and temperatures warming back into the 70s and lower 80s.
536 AM MDT Tue Oct 17 2017 12Z TAF CYCLE Strong upper level high pressure south of NM today will continue to favor overall light winds and mostly sunny skies at all terminals. Thin high clouds will thicken through this evening ahead of a weak low pressure system approaching from the eastern Pacific. Warmer temperatures continue today and Wednesday.
Windy, warm, and dry conditions are in store for the next 24 hrs as a low pressure system over central Canada and associated low pressure trough move ESE through Alberta, Saskatchewan, and Montana. The wind conditions associated with this weather system are expected this afternoon and evening, then overnight in the higher terrain. Previous Forecast: Flat upper ridge will be over Montana today. A cold front will be approaching the area from the west today. Compressional heating ahead of the front along with a thermal ridge will warm temperatures into the 70s for highs today or about 15 degrees above normal. High pressure builds into Eastern Montana on Wednesday which will diminish the winds. Temperatures will be around 15 degrees cooler than today which will be near normal for mid October.
A Pacific system and associated surface cold front will move rapidly across the Pacific Northwest today. Winds will increase across the area ahead of and behind the cold front. Strongest winds will be over the Columbia Basin and adjacent valleys, as well as over the mountain ridges. Wind advisories are currently out for the Kittitas and Yakima valleys, the lower basin and the northern foothills.
1013 AM EDT Tue Oct 17 2017 A broad area of high pressure builds in from the west today. The high will remain in control through the weekend. At the surface, high pressure to the west gradually builds to the south of the region. By the afternoon winds go variable to a light WSW direction with high pressure starting to settle on top of the region. Good radiational cooling conditions likely tonight across interior with a favorable waa aloft setup for decoupling; allowing temps to fall into the lower to mid 30s once again. Sunny skies and a gradual moderation in temps begins on Wednesday as SW return flow develops around the high to the south. Ridging both aloft and at the surface prevails through much of the period.
Winds mostly light from ne and expect a full 30 to 35 degree diurnal swing from overnight lows in the upper 30s far north to the lower to mid 40s elsewhere. /issued 357 AM CDT Tue Oct 17 2017/ A modest warming trend will carry through the remainder of this week ahead of our next major cold front set to arrive later on this weekend. In the meantime, expect the upper longwave pattern to become more progressive as the trough which brought our most recent cold front exits the eastern seaboard later today. Upper ridging will become more amplified across the mid-section of the country by mid to late week with the aforementioned warming trend getting a boost. This will push high temperatures back near 80 degrees in our northern zones and ranging through the lower 80s farther south by Wednesday.
743 AM EDT Tue Oct 17 2017 High pressure will result in gradually warming weather and dry conditions through the week. No changes needed this morning as high pressure will maintain nearly clear skies and light wind today. High pressure will remain firmly entrenched over the area through the rest of the week, ensuring a dry forecast.
517 AM MDT Tue Oct 17 2017 Latest upper air analysis shows a ridge centered over Baja California. Westerly flow over the CONUS contains some small short wave troughs. Only change will be the shift of the warmer temperatures from the west to the east for today.
440 PM MST Sun Jan 14 2018 Current surface analysis shows arctic front sliding south across SD, with warm front east-southeast of the forecast area. Upper level analysis shows low over southern Hudson Bay, with large trough covering central and eastern portions of Canada and the US. A ridge is in place along the west coast.
426 PM MST Sun Jan 14 2018 Essentially a blue bird day across eastern Utah and western Colorado today as a ridge of high pressure remains amplified over the western CONUS. Current temperatures are generally 2 to 6 degrees warmer than this time yesterday thanks to the abundance of sunshine under dry northwesterly flow. Otherwise, it'll be a quiet evening under mostly clear skies, though mid and high level clouds will increase over northwestern Colorado as a cold front dives south along the Front Range.
Winds to become southwest, then west, on Monday ahead of a cold front. VFR conditions on Monday to deteriorate to MVFR after 15/22Z as cold front approaches. Otherwise, could see NW winds around 6 knots behind cold front across TXK/ELD by 16/00Z. /issued 416 PM CST Sun Jan 14 2018/ Cloud cover has wreaked havoc on temperatures today with a wide range of afternoon readings, cracking 50 degrees over parts of lower east Texas versus south central Arkansas where we barely managed to get above freezing. By late Monday afternoon into Monday evening, a strong Arctic cold front will quickly spill south into our area with rapidly falling temperatures after sunset. This rain will quickly transition to a wintry mix of mainly sleet and snow, seeing less likelihood of freezing rain due to the rapid cooling with this deep Arctic air mass.
615 PM EST Sun Jan 14 2018 High pressure will remain over the area tonight and Monday for a continuation of dry weather.
315 PM MST Sun Jan 14 2018 Current surface analysis shows arctic front sliding south across SD, with warm front east-southeast of the forecast area. Upper level analysis shows low over southern Hudson Bay, with large trough covering central and eastern portions of Canada and the US. A ridge is in place along the west coast.
426 PM PST Sun Jan 14 2018 High pressure over the region will keep dry weather and milder than normal afternoon temperatures through Martin Luther King Jr Day across much of the central California interior, outside of persistent foggy and cloudy areas in the San Joaquin Valley.

1011 PM EST Sun Jan 14 2018 Dry and cool Canadian high pressure will build across the region through Monday.
951 PM CST Sun Jan 14 2018 Cold front is still on track to push through around 15-16Z Monday morning. This is thanks to a strong upper level low dropping out of Canada and settling across the Great Lakes region. Thus, the forecast is still on track for a strong cold front pushing southward and through the southern Plains Monday.
Decreasing winds inland this evening will allow temperatures to fall below freezing over inland zones. Temperatures near the coast will stay above freezing tonight but stronger winds there will make it feel like a freeze with wind chills in the upper 20s/lower 30s.
Should see scattered clouds Monday morning with clouds increasing during the latter part of the day as a cold front approaches from the west.
Current surface analysis shows arctic front sliding south across SD, with warm front east-southeast of the forecast area. Upper level analysis shows low over southern Hudson Bay, with large trough covering central and eastern portions of Canada and the US. A ridge is in place along the west coast.
A cold front will move across the area early Monday causing winds to shift to the north and northeast and become gusty. This will bring a chance of precipitation to the north and nudge a cold front through the area bringing much cooler weather back into the area. Any precipitation will start as rain late this evening, then transition to snow (with some potential for freezing rain) as colder air intrudes into the area. Again starting as rain with a changeover to freezing rain/sleet chances then light snow overnight Monday night.
416 PM CST Sun Jan 14 2018 Cloud cover has wreaked havoc on temperatures today with a wide range of afternoon readings, cracking 50 degrees over parts of lower east Texas versus south central Arkansas where we barely managed to get above freezing. By late Monday afternoon into Monday evening, a strong Arctic cold front will quickly spill south into our area with rapidly falling temperatures after sunset. This rain will quickly transition to a wintry mix of mainly sleet and snow, seeing less likehihood of freezing rain due to the rapid cooling with this deep Arctic air mass.
719 PM EST Sun Jan 14 2018 Dry and cool Canadian high pressure will build across the region through Monday.
A cold front will be pushing through tomorrow morning, which could produce gusty northerly winds and some lowered cigs after initial wind shift. This is thanks to a strong upper level low dropping out of Canada and settling across the Great Lakes region. Thus, the forecast is still on track for a strong cold front pushing southward and through the southern Plains Monday.
Colder temperatures there as well and may have some freezing fog later. An upper level trough and cold front move through later Mon night into Tue with rain likely. This front should clear out the low clouds and fog by Tue morning.
A strong cold front will move across the area late tonight and Monday morning. This energy is expected to close off an upper low west of the Great Lakes Monday helping drive more Arctic air well southward into the U.
In response to an approaching cold front, models indicate low-level moisture will move into our Interstate 10 corridor, around 10Z. However, the cold front may begin to move into our Interstate 20 corridor, in the 19Z to 21Z time frame; thus, the Abilene terminal may have winds from the northwest by 21Z, along with a return of MVFR ceilings. On Monday, a strong Arctic cold front will approach the Big Country by mid afternoon, then move into the Concho Valley by 6 PM. Expect temperatures to steadily fall during the afternoon behind the cold front.
617 PM EST Sun Jan 14 2018 High pressure exits tonight. Low pressure drags a cold front across Monday night, followed by arctic air for mid week. High pressure retreats into New England tonight, giving way to developing sw flow aloft ahead of the next system. This will probably allow temps to level off, especially combined with the increase in low level moisture ahead of developing warm front late. Given how dry the low level airmass, much of this may fall as virga, though do expect some flurries/light snow for a time early Monday morning, perhaps as far south as the Kentucky counties. The warm front quickly shifts into western Pennsylvania, allowing for a brief lull. A cold front will push through the region Monday night and stall just east of the area.
915 PM CST Sun Jan 14 2018 Water vapor imagery shows a broad trough of low pressure over the eastern half of the U. this evening, with the next system to affect us, starting to dig down the back side of this trough. Although dry and warmer conditions will prevail across the region on Monday, things will quickly deteriorate Monday evening and during the overnight hours, as this next system takes aim at our region.
As this ridge moves further to the east tonight, flow in the low levels will become more easterly and southeasterly. Thus, lows may be a degree or two cooler. /issued 527 PM CST Sun Jan 14 2018/ 00Z TAFS High pressure centered over the region will result in clear skies and light winds through the TAF period. /issued 345 PM CST Sun Jan 14 2018/ Mid-afternoon sfc analysis shows high pressure has shifted a little farther ewd today. now centered from the ern Great Lakes through the Ohio Valley to the lower Mississippi Valley. Water vapor imagery shows troffing in place over the ern 2/3 of the country with several weak perturbations noted nearby and farther upstream, although our airmass is so dry only some mid-level cloud cover is occurring at this time across the far nern zones from the closest disturbance.
611 PM EST Sun Jan 14 2018 High pressure will build in and crest just north of the area tonight into Monday.
927 PM EST Sun Jan 14 2018 High pressure will remain over the area tonight and Monday for a continuation of dry weather.
513 PM CST Sun Jan 14 2018 Water vapor imagery this afternoon showing a well defined upper ridge situated over the western CONUS extending into British Columbia with with a vort max dropping down the front side preparing to to push into the lower 48. hefty Pacific riding up and over the ridge was spilling into the northern High Plains. low pressure was centered over northern MN with attendant arctic front straddling the U. Aforementioned vort max dropping into the lower 48 this evening will induce synoptic scale ascent with light snow developing along axis of mid-layer ageostrophic forcing.
445 PM MST Sun Jan 14 2018 Updated Aviation Discussion A cold front will bring widespread light snow from east to west through tonight. As snow is ending some areas may see areas of freezing drizzle at times. Dry and cold conditions are then expected for Monday as high pressure moves overhead.
919 PM EST Sun Jan 14 2018 High pressure will build in and crest just north of the area tonight into Monday.
Temperatures are in the lower to mid 60s. In the low levels of the atmosphere, a large area of high pressure over the Northeastern United States will build southward down the Florida peninsula overnight. In the mid to upper levels of the atmosphere, a trough of low pressure will be located over the eastern Gulf of Mexico tonight.
532 PM EST Sun Jan 14 2018 Dry and cool Canadian high pressure will build across the region through Monday.
735 PM CST Sun Jan 14 2018 An Arctic front is rapidly progressing south across the high plains today and bringing light snow back forecast area. The models do show the front hanging up over the higher terrain to the west, so its conceivable to see the highest snow totals over our far western counties, but even still, an inch of accumulation is not likely. With Arctic air in place, temperatures will fall below zero across northern Nebraska, but stay in the low teens across our far southwest where clouds remain for much of the night.
