330 AM MDT Mon Oct 2 2017 Overall the inherited forecast is in good shape for today's snow event across the higher elevations of SE WY. Although with temps hovering around freezing during the snowfall, melting will offset some of this accumulation.
SHORT TERM (Now through Tuesday): Broad upper level trough across the western half of the US remain blocked by ridging to the east. Underneath this ridge lies the next inverted trough/TUTT drifting westward just off the Yucatan Peninsula. While South Texas remains more dominated by the ridge today, the ample moisture and llvl forcing along the seabreeze will bring the case for scattered showers with isolated embedded thunder during the day. Daytime heating will still have ample time to jump today, so have kept forecast highs in the lower 90s areawide. Aloft, the trough rotates westward underneath the eastern ridge, bringing more instability to the region.
145 AM EDT Mon Oct 02 2017 Canadian high pressure will extend into central North Carolina from the north through mid week. 850mb moisture advecting inland within the low-level ENELY flow will result in a scattered to broken stratocu layer across the southern counties underneath a thin cirrus cirrus canopy spreading eastward atop the building ridge axis. Lows tonight should average a couple of degrees warmer than last night, ranging from mid 40s north to lower 50s south. Ridging both sfc and aloft will continue right through this part of the forecast.
Cold upper low currently in Montana will shift east today as a new upper trough forms in BC/Alberta and carves southwestward through Oregon tonight, forming a closed low in ne Calif/nw Nevada Tuesday. At the surface, high pressure in Montana will expand into Idaho from the northeast Tuesday, although probably not as much as shown by the GFS.
421 AM EDT Mon Oct 2 2017 The forecast for the near term remains the same for the residents of eastern Kentucky, as a strong ridge of high pressure is expected to bring dry and pleasant weather to the area for the foreseeable future. The mostly clear and calm conditions on tap for tonight will allow temperatures to fall to chilly readings ranging from the mid 40s in valleys to the lower 50s on ridges. They all depict strong ridging through the southeast portion of the nation stretching from eastern Texas northeast through Pennsylvania. This ridge will start to be impinged from the north and west by an increasingly active flow pattern through the northern tier of the country and Great Lakes region.
229 AM EDT Mon Oct 2 2017 Longwave amplification underway across the CONUS as significant jet energy carves out a deep trough over the western half of the US. Downstream ridge axis will be anchored immediately east of the area and with H5 heights hovering near 595dm over the Mid-Atlantic through midweek. Thus, the surface temperature response today, although several degrees warmer than yesterday, will still be rather damped as southeast flow lake-shadows eastern locations and a strong subsidence inversion limits boundary layer growth. Highs in the low to mid 70s for eastern areas and upper 70s in the Saginaw Valley and west of US 23 seems reasonable. Temps will further moderate into the low 80s on Tuesday as mid-level temps warm and wind shifts to southwesterly.
235 AM EDT Mon Oct 02 2017 Canadian high pressure will extend into central North Carolina from the north through mid week. -GIH Ridging both sfc and aloft will continue right through this part of the forecast.
125 AM EDT Mon Oct 2 2017 High pressure will build in from the north today and will dominate the weather through most of this week. A cold front will approach the area by the weekend. High pressure continues to ridge south into the Carolinas tonight.
251 AM EDT Mon Oct 2 2017 An early morning surface analysis showed high pressure centered over New York state and extending south through the Carolinas. The high clouds currently over the area will move out later this morning but another round of mid/high clouds are expected to move in from the south this afternoon and evening, especially along and west of I-65. Dry weather will continue tonight into Tuesday thanks to a strengthening upper level ridge over the southeast US and mid- Atlantic.
High pressure will continue to dominate the weather pattern today with ridging anchored in place over the eastern US. A bit more moisture overhead will help keep lows tonight a few degrees warmer than the past nights, with most locations staying in the lower 50s under mainly clear skies.
Have included lower conditions at all area terminals, but low level south to southeasterly winds of 10-15kt will likely delay development of the lower conditions, especially fog.
536 AM EDT Mon Oct 2 2017 High pressure will bring moderating temperatures and dry weather for the next several days.
High pressure centered across the northeast states will maintain low level easterly flow across the area today. Afternoon high temperatures are expected to reach the low to mid 80s across most of the area.
240 AM EDT Mon Oct 02 2017 Canadian high pressure will extend into central North Carolina from the north through mid week. The mid level anticyclone will strengthen further, with its axis shifting slowly to the NW.
223 AM CDT Mon Oct 2 2017 An upper level ridge is located just east of the area early this morning leaving the area in an upper level southwest flow. This has result in the pressure gradient tightening across the region behind the low and high pressures. The southerly wind is ushering in a warmer airmass as early morning temperatures are currently in the middle 60s to around 70. The warm air mass will remain over the area on Tuesday, but there will be more cloud cover resulting in highs being a few degrees cooler than today with readings in the upper 70s to the lower 80s.
340 AM EDT Mon Oct 2 2017 Cool Canadian high pressure gradually ridges south into the local area through midweek. Aloft, the setup is starting to trend towards a blocking pattern with an amplifying ridge from the central Gulf of Mexico to the Great Lakes. Mid/upper level ridge axis continues to build along or just west of the spine of the Appalachians.
413 AM EDT Mon Oct 2 2017 High pressure will maintain dry and warm weather through the middle of the week. Strong upper level ridging will promote another sunny day with warming temperatures. High pressure will result in continued dry weather through the period with a warming trend in temperatures.
630 AM EDT Mon Oct 02 2017 Canadian high pressure will extend into central North Carolina from the north through mid week. The mid level anticyclone will strengthen further, with its axis shifting slowly to the NW.
Today Through Tuesday Night Upper level high pressure is anchored over the southeastern United States this morning, with large scaled troughing over the Pacific NW and northern Rockies. Weak energy will rotate around the southern periphery of the southeast ridge, northward into Arkansas today. The western trough will break down somewhat in terms of amplitude as two distinct upper lows develop out of the main trough. This will allow the southeastern ridge to develop back to the west towards Arkansas somewhat. Guidance shows upper ridging building overhead during the day Tuesday, with any substantial lift or jet influence located to the northwest of the CWA.
Highs today should be about a degree or two warmer than yesterday in most locations, mainly in the mid and upper 80s.
1242 PM EDT Fri Sep 8 2017 An upper level trough will slowly cross the state this afternoon into Saturday.
Current surface analysis places high pressure centered along the Manitoba/Ontario border stretching into northern Minnesota, while weak back-door frontal boundary extends from eastern Montana wrapping into central South Dakota. Upper level analysis places ridge stretching from the four-corners region northward into the lee side of the Canadian Rockies. quiet weather expected as ridge axis passes over the area. Region remains under the influence of the ridge passing east on Saturday, bringing dry conditions and seasonably mild temperatures.
The upper level ridge remains over the state with weak westerly winds aloft. Upper ridge axis over the Eastern Great Basin will continue to slowly drift towards Colorado. Temperatures today will only be slightly warmer from yesterday's readings. The upper ridge axis will push east and grow over the state Saturday, allowing for warmer temperatures and continued northward transport of subtropical moisture for a repeat of afternoon and evening storms in the mountains. The plains will remain overall stable, however some lower level moisture may provide enough CAPE for isolated storms over the Palmer and Cheyenne ridges, as well as the far northeastern corner of the state.
943 AM EDT Fri Sep 8 2017 A weak area of low pressure will swing across the Northeast through the first half of the weekend.
1249 PM EDT Fri Sep 8 2017 High pressure north of the forecast area will direct dry air into the area through Saturday night.
1159 AM EDT Fri Sep 8 2017 An upper level low over the Great Lakes will gradually move eastward and high pressure at the surface will move in from Canada.
Isolated to scattered thunderstorms are expected this afternoon and evening, mainly in SE Oregon and over the higher terrain of SW Idaho.
To the south, low to mid level ridging was noted over TX, with the WRN extent of the sub-tropical ridge stretching W across the FL peninsula. Mid/upper ridge over TX progged to continue amplifying, sending Katia SW into Mexico within the next 24hrs. This feature will erode the subtropical ridge and induce Irma to make a northward turn near the southern tip of FL, then continue N and then NW TWD the TN Valley as the two become entangled.
1023 AM CDT Fri Sep 8 2017 A trough of low pressure extending from the central Great Lakes back toward NE Illinois will be the focus for thicker cloud formation today. Otherwise, cu-rule analysis shows mostly sunny conditions prevailing elsewhere in our forecast area, under the influence of dry high pressure centered near Lake Superior. Large upper level trof over the Great Lakes region and into the eastern Ohio river valley will shift east into New England and into the mid Atlantic States by dawn Saturday. This front will pass thru dry with sw winds shifting eastward and bringing in a bit cooler air by Saturday.
814 AM PDT Fri Sep 8 2017 A trough of low pressure will bring cooler weather through Saturday, but also increasing moisture for some thunderstorms during afternoons and early evenings in the mountains and deserts.
959 AM EDT Fri Sep 8 2017 High pressure will keep us in a cooler pattern into the weekend.
Small precip chances will remain in the forecast for northeast NE on Saturday with highs in the lower/mid 80s.
With ridging overhead and generally partly cloudy skies, temperatures will warm today and Saturday. The drier airmass will continue to allow morning temperatures to be noticeably cooler.
Broad high pressure will encompass much of the eastern CONUS north of Florida and lead to gradually strengthening onshore flow as Major Hurricane Irma continues to churn across the southeast Bahamas. While we might normally be looking at a Small Craft Advisory for both increasing winds/seas, given the high bias of the wave models coupled with the likelihood of the eventual issuance(s) further northward of tropical cyclone watches, it remains prudent to hold off on that, and simply mention large swells out ahead of the approach of dangerous major Hurricane Irma.
An upper trough will bring a few showers today. There will be a better chance of rain Saturday as a cold front moves through.
1148 AM EDT Fri Sep 8 2017 A weak area of low pressure will swing across the Northeast through the first half of the weekend.
1036 AM EDT Fri Sep 8 2017 Trough across the Northeast CONUS begins to pivot northeastward today with high pressure and subsidence remaining across our region. Max temperatures are expected to be 2-4 degrees warmer today than yesterday with 850mb temperatures increasing slightly.

4 am temperatures were running 4 to 11 degrees cooler than 24 hours ago as the low pressure trough is moving into the west coast.
1254 PM EDT Fri Sep 8 2017 Cool weather and scattered showers once again are forecast today under a upper level low pressure. Dry weather is expected for the weekend under high pressure. The high should result in dry weather and mainly clear skies through the weekend as the trough exits.
99weekend as the high pres rdg remains in place acrs AR. Highs wl be mainly in the lower/mid 80s, with nighttime lows in the 50s to lower 60s.
856 AM EDT Fri Sep 8 2017 Cool weather and shower chances are expected today under a low pressure trough. Dry weather is expected for the weekend under high pressure. Cloud coverage and shower chances will return this afternoon as the area remains under upper troughing and convective temperatures are only in the low 60s.
1022 AM EDT Fri Sep 8 2017 Cool weather and scattered showers once again are forecast today under a upper level low pressure. Dry weather is expected for the weekend under high pressure. The high should result in dry weather and mainly clear skies through the weekend as the trough exits.
1111 AM EDT Fri Sep 8 2017 High pressure north of the forecast area will direct dry air into the area through Saturday night.
731 AM EDT Fri Sep 8 2017 High pressure will keep us in a cooler pattern into the weekend.
1120 AM CDT Fri Sep 8 2017 High pressure centered over AR this Friday morning with its associated dry and stable airmass to continue VFR conditions through Saturday. /issued 1103 AM CDT Fri Sep 8 2017/ Sfc ridging remains in place late this morning extending SW from the OH valley SW across AR into Cntrl TX.
High pressure over northern Minnesota this morning will move east with increasing southeasterly winds today in eastern ND and the RRV. Upper level low in SW ND to move across far northern SD and southern ND Saturday afternoon and night with it spreading a few clouds.
1103 AM CDT Fri Sep 8 2017 Sfc ridging remains in place late this morning extending SW from the OH valley SW across AR into Cntrl TX.
Overall, looking like a very nice day, with southeast winds picking up and highs a bit cooler than yesterday. High pressure over northern Minnesota this morning will move east with increasing southeasterly winds today in eastern ND and the RRV. Upper level low in SW ND to move across far northern SD and southern ND Saturday afternoon and night with it spreading a few clouds.
Ridge aloft continues over the area this morning. This feature shifts eastward today and will allow higher heights to build in from the west for warmer temperatures today and tomorrow (90s for highs), but will also allow more of that mid level monsoonal moisture into the area for at least isolated afternoon and evening thunderstorms over the western higher terrain. A couple of hot days ahead as a high amplitude upper ridge builds into Montana. An isolated shower or thunderstorm is possible over the higher terrain this afternoon, as monsoon moisture tries to work in from Utah and Nevada. as the upper ridge breaks down a bit and allows weak energy to move into the west.
BMickelson Previous short term discussion: Today begins with Northeast Montana still under a long- wave upper level ridge. Tonight and Saturday, the ridge begins to break down from the west, with NE Montana remaining under the last vestiges of the ridge. With the wind turning southerly, and the thermal ridge riding across our area, expect most highs to rise into the 90s.
615 AM CDT Fri Sep 8 2017 Cool high pressure centered over the Tennessee Valley will remain nearly stationary today as a second high moves southeast out of Canada into the Great Lakes Region. Missouri and Illinois will be on the western periphery of these two systems and clockwise flow around the highs will bring us light southerly flow today and tonight. The south wind combined with plenty of sunshine today will bring warmer temperatures to the region today. Expect highs to be between 5 and 10 degrees warmer in the upper 70s to mid 80s, which is right around seasonal normals. Tranquil weather continues tonight under the influence of low level ridging. The warmer temperatures this afternoon and continuing light southerly flow tonight will translate into warmer low temperatures tonight.
Thunderstorm chances will decrease early in the new week as high pressure builds overhead and we lose a little moisture.
750 AM EDT Fri Sep 8 2017 Aviation Low pressure will move out today and be replaced by high pressure which will sit over the area for several days. Persistent upper trough finally begins lifting out today with final batch of showers impacting mainly the southwest corner of lower MI this morning.
/issued 405 AM CDT Fri Sep 8 2017/ Water vapor imagery shows a broad trough of low pressure over the eastern half over the United States this morning, with northwesterly flow aloft over the ArkLaTex. Today will be similar to or slight warmer than yesterday, as there are a couple of disturbances moving down the back side of this trough, which will slow the progression of the rebuilding ridge. The ridge will expand into and strengthen over Texas this weekend, acting as a protecting block from Hurricane Katia.
910 AM EDT Fri Sep 8 2017 An upper level trough will move across the state on Saturday.
921 AM EDT Fri Sep 8 2017 An upper level trough extending from eastern Canada southwest into the Great Lakes will gradually move off to the east through Saturday. This will allow high pressure to build into the region from the north.
636 AM CDT Fri Sep 8 2017 There have been no changes in the forecast for the Ozarks region with mild fall like weather in place thanks to high pressure over the area. Todays temperatures will be a bit warmer than the past few days with low 80s expected. High pressure will be in control of the regions weather through the next 24 hours.
623 AM CDT Tue May 23 2017 An upper low is currently centered over Minnesota, and is forecast to steadily move southward today into Iowa. As it does so, it will advect cooler air into the area, both at the surface and aloft. Skies will start to clear and winds will start to decrease from west to east as high pressure builds in, but lows will depend heavily on how quickly this happens.
Expecting mostly sunny skies this morning to become partly cloudy as Pacific moisture streams up and around the high pressure ridge currently over the region. BMickelson Previous short term discussion: Warm and dry weather conditions are expected for today as an upper level ridge advances across the region with rising heights. The ridge axis will shift downstream of the CWA as the next low pressure system approaches from the west on Wednesday. This system will push a cold front through the area with a chance for showers and general thunderstorms, particularly in the afternoon. Given these arguments will let the High Wind Watch ride and future shifts can decide on the upgrade. Main feature for midweek on continues to be a strong upper low swinging across western Canada.
1104 AM CDT Tue May 23 2017 Relatively cool air over the cloudy region in the southeast with much warmer air over the sunny west and central creating thermal/pressure differences and enhanced winds the earlier forecast did not account for. Updated clouds and raise highs into the lower 70s northwest. High pressure will move later today. It will be breezy today across the James Valley as the pressure gradient steepens ahead of the approaching high pressure center. An upper low across southern Canada will pull a cold front through western North Dakota Wednesday Afternoon. Scattered showers will form along the cold front.
High pressure ridging will continue to be shunted south and east away from the area as a frontal boundary remains quasi-stationary over the Deep South and southeast U. The high pressure ridge axis remains suppressed to the south.
931 AM MDT Tue May 23 2017 Weather remains quiet across Montana this morning, as a ridge of high pressure is dominating weather across the area. Upper ridge will dominate our weather today into tonight. The ridge will slide eastward tonight, allowing for an upper trough and associated surface cold front to approach the region from the west on Wednesday. Just ahead of the cold front, a few showers and thunderstorms are possible.
As a cold front spreads southward, drier air will move in, lifting CIGs, and clearing the thunderstorm activity to our south. A synoptic cold front was moving south through the Panhandle region into the Caprock of west Texas. This cold front will move south through our area today. Expect the precipitation to move into the southern half of the forecast area by this afternoon, and out of the area entirely by this evening as drier, more stable air filters in behind the cold front. Tonight, with clearing skies, diminishing winds, and dry air behind the cold front, temperatures will be cool with lows dropping into the upper 40s to mid 50s. (Wednesday through memorial Day) Dry and warmer weather can be expected across West Central Texas Wednesday through the first part of the upcoming holiday weekend.
VFR will continue early tonight, but MVFR cigs along with VCTS will be possible at the northern terminals after 06Z as clouds and rain chances increase ahead of a cold front, with these conditions spreading to the southern terminals after 09Z. Additional upper energy moving through the base of the trough will pass over the state for Wednesday and allow for some strong to possibly severe storms. Winds will increase today across the area ahead of a cold front and allow for a Lake Wind Advisory. Highs Wednesday will be in the lower 80s to near 90.
1021 AM EDT Tue May 23 2017 Despite considerable high translucent cirrus spilling into our county warning area from the eastern Gulf of Mexico, temperatures are already in the lower to mid 80s along the island chain. Surface wise, a lengthy western Atlantic ridge axis extends across extreme south Florida and the Florida Keys and into the southeast Gulf of Mexico. A deep layered western Atlantic ridge will be anchored near our region, resulting in limited moisture confined below 850 and above 500 mb.
Warm and dry conditions are expected to persist today under an upper level ridge. Tomorrow's temperatures will be 10 or more degrees cooler due to a dry cold front sweeping through that is associated with an upper low passing to the north of the area. Ridging over the area will continue to bring dry and warm conditions today, along with light wind. An area of low pressure will move east over British Columbia this evening. As this system moves southeast through Wednesday, it will send a mostly dry cold front south across the forecast area on Wednesday.
Ceilings are deteriorating this morning as a cold front begins to make its way into the area. /issued 309 AM CDT Tue May 23 2017/ Current obs are showing scattered showers and isolated thunderstorms are developing to our north behind a cold front moving into the Permian Basin, and models are in good agreement that this area of rainfall will spread south into our CWA later this morning. Stability is increasing behind the cold front so no severe storms are expected.
A nearby upper low will continue bringing isolated to scattered showers and sprinkles today as it digs south through Minnesota into Iowa.
1130 AM EDT Tue May 23 2017 High pressure will bring dry weather and a mix of sun and clouds through Wednesday.
It appears the highest chances for light rain will stay near and just south of the Red River through the middle of the afternoon. Patchy MVFR conditions continue across areas southeast of the cold front moving through the area today, but this is becoming less of an issue at the TAF sites with the arrival of the front. /issued 509 AM CDT Tue May 23 2017/ A cold front will move through the area this morning. Overall, cooler weather is expected the next couple of days, before warming significantly late this week as upper ridge moves over the Plains.
