823 AM EDT Wed Oct 12 2016 High pressure pulls off to the east toward the Canadian Maritimes today while an upper level trough approaches from the west. A cold front will cross the area Thursday night with showers along and ahead of it.
1109 AM CDT Wed Oct 12 2016 Sly flow ahead of a cold front draped across central OK/N TX has allowed for a good moisture pool over our region, particularly over E TX/SE OK. A cold front will approach from the northwest and will slowly move across the area after 12/06z before becoming stationary Thursday morning. Could see isolated to widely scattered convection mainly across Deep East Texas and Southeast Oklahoma into the evening ahead of an approaching cold front.
1118 AM EDT Wed Oct 12 2016 High pressure to our east will allow for abundant sunshine, above normal temperatures, and an increasing southerly breeze this afternoon. A cold front will pass through on Thursday morning and early afternoon bringing showers to mainly the northern and central mountains.
Winds were generally light and variable in the lower half of the troposphere and then primarily from the northwest in the upper half of the troposphere.
Weak upper level high pressure will shift east across the region today. Winds will be generally light, though they should become 10 to 15 mph over the south end of the Grande Ronde valley and mountain ridges in east-central Oregon. Models indicating rainfall totals could be 1-2 inches for the lower elevations and 3-7 inches for the mountains.
strong subsidence from persistent subtropical ridging and lack of sufficient moisture values will result in nil precip chances.
1236 PM EDT Wed Oct 12 2016 High pressure will maintain dry weather today before showers return with a cold front early Thursday. High pressure will continue to slide eastward as a cold front approaches. Southerly flow in advance of the boundary and mostly sunny skies should support high temperatures that are about 10 degrees warmer than average today. Shower chances will increase after midnight as the upper trough over the northern Great Lakes swings a cold front toward the region. Front will continue to make progress across the upper Ohio Valley early, followed quickly by building high pressure. With northwest flow and moisture lingering in the high terrain, have kept chance PoPs in the forecast through Thursday afternoon.
A cold front will approach from the northwest and will slowly move across the area after 12/06z before becoming stationary Thursday morning. Could see isolated to widely scattered convection mainly across Deep East Texas and Southeast Oklahoma into the evening ahead of an approaching cold front.
A cold front/wind shift, currently located southeast of KGAG and KWWR, will continue to progress from northwest to southeast across the rest of the terminals today. Southerly winds ahead of the cold front will shift and become gusty from the north. /issued 417 AM CDT WED OCT 12 2016/ A seasonably strong cold front will progress from northwest to southeast today. Opted to go colder and faster with the cold front based on current observations and high-resolution models. Also increased the magnitude of temperature gradient across the cold front this afternoon. The cold front is forecast to be near the I-44 corridor late morning.
Dry weather and slightly cooler than normal temperatures can be expected over the central California interior through Thursday night.
608 AM CDT Wed Oct 12 2016 The well advertised cold front has crossed into the CWA as of early Wednesday morning and will continue to work its way southeast through sunrise. This has brought 60 degree temperatures down to the lower to mid 50s behind the frontal boundary. Afternoon temperatures will linger in the lower 50s across most areas, with values approaching the mid 50s well south of the Missouri River. Though steep mid-level lapse rates are noted, marginal elevated instability overhead a capped environment will reduce the potential for strong storms ahead of the cold front. Could see temperatures at or below freezing for northwest Missouri tonight, and temperatures along and south of the Missouri River dipping into the mid 30s with radiational cooling underneath clearing skies.
Cold front moving through northeast Oklahoma late this morning, currently just north of I-44.
1245 AM EST Mon Feb 13 2017 A cold front will sweep through late tonight.
Vsbys should improve to VFR after 14Z, but MVFR cigs will likely linger through most of the remainder of the Taf forecast period as additional moisture associated with a cold front moving south into the region impacts the region. /issued 717 PM EST Sun Feb 12 2017/ High pressure east of Florida continues to ridge west over central Florida producing pleasant weather overnight. The high pushes south by Monday afternoon as a weak cold front moves south toward the area.
336 AM EST Mon Feb 13 2017 High pressure will build over the area through Tuesday.
412 AM EST Mon Feb 13 2017 High pressure will ridge across the region from southwest to northeast through the day.
348 AM EST Mon Feb 13 2017 Clear and breezy conditions are impacting the state this morning in the wake of a cold front sagging into south Georgia. Light radar returns have diminished entirely, and a dry forecast is in place through the short term with high pressure returning to the region. Gusty winds have already begun settling this morning, but will remain at or near Wind Advisory criteria in the higher elevations of northeast Georgia through approximately 18z today. Temperatures will be slightly cooler today with the influence of the colder air mass. High temperatures will be a few degrees warmer on Tuesday.
1137 PM MST Sun Feb 12 2017 Current surface analysis shows high pressure centered over southern Neb. Upper level analysis shows near zonal flow across the northwest and north central US, with low pressure cut off from the main flow across the southwest US and northwest Mexico. Quiet wx to continue through the short term period as upper low over the southwest US tracks well to the south of the region and ridge builds over the northwest US tonight and Monday. Ridge over the northwest US early in the week will slowly shift east into the plains late in the week.
327 AM CST Mon Feb 13 2017 A rather highly amplified pattern will persist for the next 36 hours, with fast NW flow aloft continuing to prevail over the western Great Lakes region underneath the western periphery of the large-scale upper trof that remains in place across the eastern U. A couple of fast-moving disturbances will traverse the region today and tonight as the amplify while moving toward the mean large-scale trof axis, each bringing chances for precipitation. In between these two waves, weak low level lift is forecast to persist tonight, especially across northeast MN, and with the loss of deep-layer ice for a 6-12 hour period between waves, freezing drizzle may become a bit of nuisance tonight/early Tuesday morning. A deepening trough over the Great Lakes will result in meridional flow across the western Great Lakes on Tuesday night.
427 AM EST Mon Feb 13 2017 High pressure will build into the region from the west through tonight.
230 AM CST Mon Feb 13 2017 Mid level low pressure is beginning to lift out of the southwest US. Despite the moisture and lift spreading over the area the low levels remain fairly dry therefore precip is struggling to reach the ground. Given the depth of the low level dry air a decent amount of lift would be needed to saturate this layer. Skies will clear from north to south tonight, which could set up a gradient in the low temperatures.
Cold advection has kicked into full gear behind the departing cold front with temperatures falling back into the 50s this afternoon. High pressure will build into the area Monday setting up a mostly sunny day. After the cooler start, temperatures will bounce back into the mid 40s by the afternoon. Ridges may stay closer to 30. In between the two, we will have fair wx with benign westerly flow and low level warm air advection in advance of a cold front associated with the northern system.
The trough in the northern branch of the upper flow moves east of the region this morning. A stronger northern branch trough moves into the northern plains and great lakes region by late Tuesday and begins to come into phase with the low center as it moves through the southern plains. As a result, expect a chance of a rain and snow mix across the south/southeastern portion of the forecast area between tonight and Monday night with dry conditions and warmer temperatures into Tuesday as the amplifying ridge over the intermountain west begins to move over the Rockies and High Plains region.
Will continue a dry FROPA process off digging upper low acrs the Northwestern GRT LKS Mon night, with lingering deep cyclonic flow acrs the mid to upper MS RVR Valley driving rather breezy conditions on Tue. Steep northwesterlies to lee of amplifying western Rockies upper ridge, to dump H85 MB cold pool down into the GRT LKS out of the northwestern Hudson Bay region later Tue night into Wed morning. Ongoing mixing winds in llvl cyclonic pressure gradient, no snow and some CAA stratocu/AC to limit cold temp potential but will still go with cooler of guidance lows in the low to mid 20s for much of the local area by Wed morning.
146 AM EST Mon Feb 13 2017 A cold front crossing the region will move off the coast around midnight. Cool high pressure will build in for the first part of the work week.
1100 PM MST Sun Feb 12 2017 Tonight an upper level low wl be moving eastward acrs nrn Mexico, just south of AZ. At the lower elevations, temps should generally be warm enough for rain rather than snow. With that upper low remaining to our south Mon night there wl still be chances for pcpn, mainly over the southern quarter of the state, with some additional light accumulations of snow in the mtns. The upper low then track into TX on Tue and drier conditions and warmer temps are expected over southern CO, along with some breezy northerly winds over the eastern plains.
/issued 915 PM CST Sun Feb 12 2017/ Temperatures across the Mid-South continue to drop behind the cold front that is now located near the Gulf Coast. /issued 258 PM CST Sun Feb 12 2017/ The cold front has passed Tupelo and will exit the CWA by 4 PM. Cooler and drier air will advect into the Mid-South, with dewpoints in the 20s area wide by sunrise. High pressure will build over the area, maintaining relatively light winds. Temperatures are forecast to remain in the low/mid 50s. An upper-level low, displaced from the primary trough over the eastern CONUS, will be moving east across the Southern Rockies Monday night, ejecting into the Plains on Tuesday.
Models have the strong southwesterly flow aloft decreasing overnight with a weak upper trough axis to move into the western CWA by late Monday afternoon. This is associated with a closed upper low now over Baja California, Mexico that the models show moving east-northeastward into south-central New Mexico at 00Z Tuesday. The low level wind and pressure fields show drainage patterns overnight, then fairly decent north- northeastern upslope on Monday. 5 C warmer than this afternoon's highs. Minimum temperatures overnight will cool quickly as well with the high mountain valleys seeing single digits likely with light winds and no cloud cover.
327 AM EST Mon Feb 13 2017 Nam shows a closed 500 mb low over NY this morning with a closed low in the Gulf of California. The highest pops would be in the northern cwa near Lake Superior. While no significant precip is evident for Fri through the weekend, temperatures will be on the rise as upper ridging builds over the region. Then, passage of a sfc trof across western Upper MI this evening should result in MVFR cigs developing at KIWD/KCMX. Freezing spray, along with some heavy freezing spray, is expected over central and eastern Lake Superior Tue night and Wed.
309 AM CST Mon Feb 13 2017 High pressure over the Mid South today will move to the east by Tuesday as another storm system approaches from the west. An upper level low pressure system over northern Mexico today will move northeast over the next couple of days before becoming absorbed by a larger upper level trough digging across the eastern United States. As the upper low lifts northeast through Tuesday.
/issued 719 PM EST Sun Feb 12 2017/ High pressure will slowly weaken tonight over the Western Atlantic waters keeping the weather dry over South Florida. High pressure over the Florida Peninsula will break down tonight into Monday allowing for a weak cold front over the Tennessee Valley to move southward into Northern Central Florida.
Temperatures warmed into the 50s and even the low 60s along the Arkansas border. North winds will continue tonight bringing temperatures into the low 30s. As the previously mentioned upper level low pressure system tracks along the Interstate 20 corridor, the GFS and the ECMWF suggest that the northern edge of a precipitation shield could reach far southern Missouri Monday night into early Tuesday morning. Although some models indicate that the low level trop could facilitate a few flurries or light snow.
Most guidance indicates at the lower end of MVFR but we are cautious it may be into IFR range. We added start of precipitation as well, with short term solutions in pretty good agreement on the start of rain and freezing rain across the area mid to late Monday morning. Upper level low pressure system expected to move to near El Paso by the end of this TAF forecast.
830 PM PST Sun Feb 12 2017 Strong high pressure will bring a good chance of sunshine to much of the Inland Northwest Monday and Tuesday.
942 PM PST Sun Feb 12 2017 Strong high pressure will bring a good chance of sunshine to much of the Inland Northwest Monday and Tuesday.
Low level thermal trof continued to slide off to the east overnight as steering winds briefly become more west to northwest for today into tonight ahead of mid-level short wave and eventual weak surge of colder air later tonight into early Tuesday. Will be quite windy in wake of sfc/850 cold front with temps taking a tumble Tuesday evening.
350 AM EST Mon Feb 13 2017 Scattered snow showers will continue this morning but conditions should improve later today as high pressure builds overhead. Continued improvement is expected this morning has high pressure builds and the influencing low pressure system shifts further east. Otherwise, once precipitation ends, high pressure will maintain dry conditions across the area through Tuesday. trough. A cold front will dive through, returning cold advection and northwest flow.
Models show an upper level ridge building northward across the west coast of the United States on Monday. This ridge will gradually become an upper level high centered over Montana/Idaho and remain nearly stationary or move slowly southeast into Wyoming on Tuesday. This will result in slowly increasing temperatures across the area with highs reaching the low 50's in a few areas by Tuesday afternoon. A quiet weather pattern should prevail early in the forecast period w/ high-amplitude upper-level ridging in place over the Rockies. H7 temperatures of +4 to +6 deg C, combined w/ deep subsidence and dry air aloft will support widespread highs in the 60s to around 70 for the high plains on both Wed/Thu.
247 AM CST Mon Feb 13 2017 High pressure was centered over the central CONUS this am as clear skies in the area were allowing temperatures to drop into the 20s this morning. To the south and west of the area, a cut off upper level low was slowly lumbering east across the southern Rocky Mountains. With northwest flow aloft, this low is forecast to stay south of the area through the short term period.
/ISSUED 946 PM CST Sun Feb 12 2017/ Though the cold front is making its way through the area this evening, dewpoints remain in the low to mid 60s across all of Southeast Texas at this hour. Do anticipate a slightly cooler airmass to filter in to most inland areas as winds back to the ne/e. Still anticipate a sfc wave/low to develop along the stalled front in the vicinity of the Big Bend area on Monday in advance of the next approaching upper trof. That being said, with the high PW's I am still concerned with potential high rain rates themselves versus the overall amounts.
(46) Main concerns in this forecast cycle are any low chances of rain with the cold front as it drifts south over AR. The cold front is slowly making progress south, bringing in a cooler and drier airmass, as well as an elevated north wind flow. Aloft, currently zonal flow was over the region, while low pressure troughing to the east, and an upper ridge over the western Plains. Tonight Through Tuesday Night This afternoon to tonight, the front will continue to drift south, taking any rain with it, and as the high pressure builds into AR, the drier air will break up the clouds. Clear to becoming clear will be seen tonight, with lows cooler in the 30s to lower 40s. Highs will be in the lower to mid 50s. Highs on Tuesday remain in the lower to mid 50s.
High pressure will return with fair and mild conditions for Tuesday with a much lighter wind.
940 PM MST Sun Feb 12 2017 A low pressure system moving slowly across the Desert Southwest and northwest Mexico will mean a chance of showers and a slight chance of thunderstorms tonight tonight with decreasing chances through Tuesday.
Conditions should improve later today as high pressure builds eastward. High pressure will start to slide eastward on Monday, bringing an end to snow shower activity. A quick moderation in temperature is anticipated Tuesday as another reinforcing upper trough digs over Ern Canada.
SHORT TERM (Today through Tuesday):Well advertised arrival of the cold front still on track for Tuesday as the H5 trough sweeps across North Texas. But the arrival of the surface forcing with the front during the morning, along with the passage of the H5 trough through North Texas, will bring a good shot for showers and a few thunderstorms.
301 AM CST Mon Feb 13 2017 High pressure centered over northwest Missouri early this morning will move slowly southeast across the area today. Skies will mostly cloudy today as sct-bkn high clouds stream northeastward ahead of a upper low moving into the southern High Plains. Temperatures the past few days have verified at or above the warm side of guidance, so will go with the warmer GFS MOS guidance today.
/06Z ISSUANCE/ Patchy valley fog may partially obscure terrain in the lower river valleys with all TAF sites except KCOD and KCPR showing VCFG through 16-18z Monday. Otherwise VFR conditions will prevail through 06z Tuesday with a weak, dry cold front pushing south across the area Monday morning, accompanied by some mid and high clouds and a subtle wind shift from the north. High pressure aloft will fold across the area Monday night bringing in warmer air aloft, steeper inversions over the valleys, and possibly more extensive areas of fog development Tuesday morning across the lower central basins (vicinity KRIW-WRL-KGEY) and southwest Wyoming (KRKS-KBPI route).
VFR will continue for all Mid Tn taf sites through the next 24 hours as dry high pressure moves in from the northwest.
An upper level low pressure system will cross New Mexico from the west tonight through Tuesday with a few to several inches of snow mainly along and east of the continental divide. That said, there will be a wintry mix of light snow, sleet and freezing rain tonight into Monday along and east of a line from Dunken to Tucumcari.
Warmer monday, then cooler Tuesday (west of the mountains) as a coastal eddy spins up some low clouds.
Issued by National Weather Service Louisville KY 253 AM CST Mon Feb 13 2017 A surface analysis this morning showed high pressure over central Missouri with light northerly winds across the region. For today, plan on quiet and dry weather as the aforementioned high pressure slides east, reaching central Kentucky later this afternoon and evening.
120 AM MST Mon Feb 13 2017 Ridge of high pressure will dominate the weather for the upcoming week with sunny skies and warming temperatures each day.
Upper low was moving into the Baja region this afternoon and will move slowly east-northeast into southern New Mexico by Monday evening. This upper low will shift gradually east across the southern Plains through Tuesday. Otherwise, a secondary push of cooler air will backdoor eastern Kansas Tuesday night. Darmofal Another upper low within the southern stream will traverse east across the southern Plains later in the week with upper ridging progged across the northern Plains into the Upper Midwest.
Winds overnight have been well below advisory criteria at all observation points, and the trend through the morning should be diminishing winds as high pressure builds in from the west.
Clear skies will remain through the night as high pressure builds east. Just enough of a gradient will remain in place tonight since the high is not centered on top of us, so not expecting temps to completely bottom out, but valley areas should be the coolest nonetheless. These numbers were a bit cooler which seemed reasonable. Also kept overnight lows warmer in this area because of the increased mixing. There will be a subtle cooler air mass glancing the region on Tuesday, so expecting highs to be a touch cooler compared to Monday, but still above normal for this time of year. The extended features an upper ridge transitioning into the Plains.
343 AM CST Mon Feb 13 2017 Surface observations shows a cold front slowly moving south across the forecast area early this morning. Water vapor imagery shows an upper level low is currently moving eastward across the Baja of California and northwest Mexico. This low is still expected to track into eastern Texas by Tuesday afternoon. At the same time, another upper trough will be dropping south across Canada to the Great Lakes.
1116 PM CST Sun Feb 12 2017 Benign weather will continue across the forecast area in the short term with mild days and cold nights as area remains between northern and southern stream troughs. Closed upper low over northern Baja this afternoon will begin to track east into northern Mexico tonight, reaching the southern Rockies and Texas high plains on Monday. Initial northern trough coming across the northern plains on Monday will help drive the southern storm system further south and east Monday night and Tuesday as it tracks east across the southern plains.
1011 PM PST Sun Feb 12 2017 Strong high pressure will bring a good chance of sunshine to much of the Inland Northwest Monday and Tuesday.
Winds should be under 10 kts tomorrow as high pressure builds into KY/TN.
Monday will see highs climb into the 40s in most locations, likely reaching the lower 50s in areas with no snow cover. On Tuesday, upper low pressure moves southeastward across the Great Lakes bringing a bit of back door cooling into the forecast area. Therefore highs will still be in the lower to mid 40s which is 10 to 15 degrees above normal.
311 AM CST Mon Feb 13 2017 An upper level low currently over northwestern Mexico is slated to be the next weather maker for eastern Oklahoma and western Arkansas. Rain showers associated with this feature are expected to begin to move into eastern Oklahoma late this afternoon with the best chances of rain showers Tonight into Tuesday as the upper level low weakens and moves out of the southwest and across the Southern Plains. It continues to look like the higher rainfall totals will occur south of Interstate 40. The remainder of the work week will be dry as high pressure controls at the surface and aloft.
Aloft, thick cirrus streams overhead, well ahead of a strong closed low over Baja California at midday. Clouds will remain thick, with gradually lowering ceilings, as upper low begins to approach through Sonora Mexico. Cloudy and cold, with temperatures actually running several degrees below normal, in the low to mid 40s. Once the storm system moves out Tuesday we turn into another dry period with an upper level ridge moving into the central plains.
