643 AM CDT FRI OCT 28 2016 High pressure will continue to move to the east today while a low pressure area moves across the northern US into the Great Lakes region by tonight. The gradient between this high pressure and low pressure, and associated cold front, will cause surface winds to increase today with gusts increasing to over 20mph by this afternoon.
/issued 406 AM CDT Fri Oct 28 2016/ (Today and Tonight) Upper level ridge of high pressure to remain in control across the Southern Plains, with quiet weather across West Central Texas.
1003 AM EDT Fri Oct 28 2016 Low pressure will slowly move east through southern New England today, bringing heavy rain for most of the region with snow at the highest elevations. A ridge of high pressure will build in from the west tonight.
Initially there was concern that this could hinder temperatures getting into the lower 80s but as models show the dissipation by peak heating time combined with the downsloping over the lower foothills I have only dropped the highs a degree across the Front Range with record breaking temps still in place. For tonight moisture will increase in the nrn mtns north of I-70 as a wk upper level trough clips nrn CO mainly after midnight. Models have the upper ridge flattened down somewhat with a weak upper trough to move across the CWA on Saturday. There is more upper ridging Saturday night.
1120 AM EDT Fri Oct 28 2016 High pressure returns this afternoon through Saturday.
748 AM EDT Fri Oct 28 2016 Dry weather can be expected today and Saturday as high pressure builds across the area.
/issued 340 AM CDT Fri Oct 28 2016/ Not much change expected over the next several days, as an upper ridge remains over the central CONUS, with high pressure dominating the weather pattern across the region. Another very warm day is on tap today, with highs this afternoon expected to be in the 80s for most of the area, with upper 70s over higher terrain, as well as a couple readings in the lower 90s possible through the Rio Grande Valley.
720 AM CDT Fri Oct 28 2016 High pressure over the Ohio Valley will move eastward into the Mid Atlantic States.
1018 AM EDT Fri Oct 28 2016 High pressure will prevail through the weekend.
Low pressure at 11z south of Brandon Manitoba with front/trough to west of Rugby to near Bismarck. What has occurred is that the low clouds have been clearing overnight from the south and the low clouds have cleared out of DVL, GFK, TVF sites. Low pressure will move east through southern Manitoba today and a cold front/trough of low pressure will move through with winds shifting the west over eastern ND this morning-midday and into NW/WC MN later today. Some clearing Saturday night with high overhead will give lows near the freezing mark.
634 AM CDT Fri Oct 28 2016 A few record or near record high temperatures are expected today and Saturday with breezy southwest winds within the low/mid level thermal ridge where highs will climb into the mid and upper 80s.
645 AM CDT FRI OCT 28 2016 High pressure on the surface and aloft will dominate through the period with light southerly winds and widespread VFR conditions.
based on sounding, do expect maximum temperature forecast today to be in the ballpark enough not to change at this time although temperatures may be a degree or two cooler in some locations due to the sustained east flow and lingering clouds. Moisture advection will continue through Saturday as a mid/upper low approaches from the east on Saturday.
Upper level closed low south of Louisiana streaming considerable cirrus across the eastern Gulf and over the peninsula with SW flow aloft.
1003 AM EDT Fri Oct 28 2016 High pressure crosses Today, but maintains dry weather across the area much of the weekend.
717 AM CDT Fri Oct 28 2016 A progressive pattern across North America will result in a weak area of low pressure moving across the upper Midwest and then a high building across the northern Plains today into tomorrow. Rain chances will be minimal across the Northland given the warm frontal zone will be well to the north of the international border, but expect abundant cloud cover as low- level stratus persists while mid/high level clouds move across the region aloft. Overnight cloudy skies will persists in the northwest flow behind the low. Showers possible north of the Iron Range as the cooler air aloft introduces a bit of instability. Cooler Saturday but temperatures still on the mild side of normal. Light northwest winds as high pressure will be building in from the west through the day.
Dry and warmer weather is expected through Saturday as the Ohio Valley remains under the influence of high pressure.
1003 AM EDT Fri Oct 28 2016 Lake effect showers will slowly wind down this afternoon as high pressure moves into the region. Regions that will see a few breaks in cloud coverage Friday night will see temps falling into the lower 30s, while areas where cloud coverage manages to hold, will remain in the upper 30s. As the low moves from NE Ontario into Quebec a cold front will begin to approach the area by afternoon bringing increasing clouds and some scattered showers. Low late in the pd will bring cooler air and a chance for shwrs. Ridging over the eastern CONUS slowly starts to strengthen and high pressure as the surface starts to build.
743 AM EDT Fri Oct 28 2016 Aviation High pressure will bring fair weather today but the chance for rain will return by late tonight and Saturday as low pressure tracks north of Lower Michigan.
933 AM PDT Fri Oct 28 2016 A Pacific low pressure system will bring showers and perhaps a few thunderstorms today, mostly to northern areas of SoCal.
706 AM EDT Fri Oct 28 2016 High pressure will prevail through the weekend.
1018 AM EDT Fri Oct 28 2016 A dry cold front will move offshore today, followed by high pressure through the weekend with above normal temperatures in the daytime.
1032 AM EDT Fri Oct 28 2016 Morning fog has quickly dissipated with the rising sun as high pressure quickly builds in behind a frontal passage that occurred yesterday. allowing temperatures to soar well into the 70s to perhaps the lower 80s (in the Central and Southern Valley). Chattanooga Airport, TN 83 53 85 55 / 0 0 0 0 Knoxville McGhee Tyson Airport, TN 80 50 82 55 / 0 0 0 0 Oak Ridge, TN 79 50 82 55 / 0 0 0 0 Tri Cities Airport, TN 73 44 78 49 / 0 0 0 0.
536 AM MDT Fri Oct 28 2016 Current IR satellite loop shows cloudy skies over most of the forecast area as high cirrus moves eastward into the High Plains. these winds will begin to impact the high valleys and high plains of southeast Wyoming by late this morning where gusts up to 40 to 45 MPH are possible. There is a potent upper level trough off the California coastline which will move eastward into the Great Basin and eventually Wyoming/Montana late tonight. High temperatures will be a few degrees cooler compared to yesterday mainly due to the persistent cloud cover. The other forecast concern will be winds across the wind prone areas of southeast Wyoming Friday night as a weak cold front moves towards the area. gusts between 50 to 55 mph are still possible along the higher elevations of I-80.
With an upper ridge axis out of the srn Plains states translating ewd, afternoon temps should have little trouble climbing back into the lower/mid 80s for most locations, with mostly sunny skies continuing across the region.
1158 AM EDT Fri Oct 28 2016 Building high pressure will slowly decrease cloud cover and keep the area cool and dry today. Warmer temperatures and increasing precipitation chances return Saturday. Still think that overall coverage will diminish as enough mixing of dry air takes place to lift and scatter out the clouds with high pressure in place. Upper level flow will become zonal on Saturday, but we will still see an influx of warmer air, as the lower and mid-level flow turns to the southwest.
/issued 422 AM CDT Fri Oct 28 2016/ Water vapor imagery indicates eastward expanding upper ridge over the mid-section of the country with cirrus spilling out across the Plains. This general trend will continue on through the weekend with a slight uptick in temperatures due to the eastward expanding ridge axis becoming more east-west oriented across the Gulf coast states.
1219 PM EDT Fri Oct 28 2016 A dry cold front will move offshore today, followed by high pressure through the weekend with above normal temperatures.
lowering interior surface humidities into the lower to middle 40%s/60% along coast. Wind speeds will remain under 10 mph per this regionally flat pressure gradient (provided by high pressure centered over eastern Texas). WV imagery clearly showing the upper ridging over TX and an upper low over the Gulf south of LA. The upper low will retrograde to near the Lower TX coast by Saturday morning so this should keep the moist inflows going across SETX and focus rain chances mainly over the Gulf waters and possibly into the coastal counties. With the upper ridge dominating the weather while traversing TX expect temperatures to continue well above normal through the weekend.
623 AM CDT Fri Oct 28 2016 Very mild and warm today with southerly winds and ridging aloft. While there is quite a bit of cirrus, it will probably be thin enough to allow plenty of sunshine, along with slightly warmer 850 mb temps than yesterday. Highs today should easily reach the lower 80s, with near record warmth expected.
527 AM MDT Fri Oct 28 2016 Current surface analysis shows low pressure over southeast SK, with warm front extending southeast through the central and eastern Dakotas. A cold front extends southwest from the low across MT into southern ID. Upper level analysis shows ridge axis over the high plains, with low pressure remaining off the west coast. Warm weather will continue across the area today, before cold front to the northwest sags south across the area later today and tonight. A little snow could mix in across the highest elevations of the Black Hills late tonight/early Saturday. Cooler air in place with the clouds will keep highs only in the upper 40s to mid 50s.
711 AM EDT Fri Oct 28 2016 With the low sun angle of late October, dense fog at TRI will probably persist for a few more hours, with at least some reduced visibility possible until noon. Otherwise, no aviation concerns today as high pressure will provide clear skies and light winds through the day at all sites.
/12Z TAFS/ Aside from some very light patchy fog at AUS through 13-14Z, VFR conditions with southeast 5-10 knot winds are expected at all TAF sites today under high pressure.
909 AM MDT Fri Oct 28 2016 Weak Canadian cold front oozing into our cwa with a recent shift to north winds at Billings, but fairly strong SW winds remain at Livingston and along the foothills as of 9 am. Fringe of the rain shield appears to set-up somewhere near the Billings area through the night so not completely sold on some of the higher rainfall totals that have been advertised by ECMWF. Colder air makes it's way into the Beartooths a little earlier on Friday night which will increase totals to 6 to 10 inches along the highest peaks. Anticipating highs to only reach the low 50s on Saturday.
The TN Valley remains between a broad upper level trough over the east coast, and a strong upper ridge that covers much of the western and central CONUS. Northwest flow aloft was sending weak disturbances along the western periphery of the trough, however given the dry airmass in place, the only impact from these disturbances is high level clouds. Temperatures have already fallen into the low to mid 50s under clear skies and calm winds. Therefore, with dewpoints in the lower 50s, the potential for fog still remains likely and will keep the mention of fog in the forecast. The upper ridge will slowly build in across the area and winds will begin to veer eastward. Temperatures will quickly warm and reach into the lower to mid 80s this afternoon and a few spots may approach their record values.
Breezy northwest winds will set up behind this weak cold front, but do not think it will be much more than a 2 to 4 hours of 15G25 mph type winds. BMickelson Previous short term discussion: A cold front moved through Northeast Montana early this morning. It will breezy and cooler behind the surface front today.
1005 AM EDT Fri Oct 28 2016 A weak cold front will move through Eastern North Carolina today.
1046 AM EDT Fri Oct 28 2016 High pressure over Ohio will build over the area through Saturday before dropping south.
Meanwhile, local radars are detecting widely scattered patches of mostly light rain over the Lower Keys and the adjacent gulf and Atlantic waters. Surface wise, a large region of high pressure remains anchored over the entire eastern United States with a trough of low pressure lingering in the northwest Caribbean sea.
12Z JAN sounding reveals lower atmosphere just a touch warmer than was the case yesterday and, considering most other sensible weather parameters being equal, temperatures should top out a degree or so warmer this afternoon. The abnormally warm and dry weather pattern that we've experienced for much of October will continue today as a broad upper ridge centered over the Central U.
1015 AM CDT Fri Oct 28 2016 Upper ridge continues to increase its influence across the srn CONUS.
809 AM EDT Fri Oct 28 2016 Building high pressure will slowly decrease cloud cover and keep the area cool and dry today. Warmer temperatures on Saturday. High pressure and warm advection will decrease cloud cover today, allowing temperatures to warm just a bit, but still remain below seasonal averages. Upper level flow will become zonal on Saturday, but we will still see an influx of warmer air, as the lower and mid-level flow turns to the southwest.
1120 AM EDT Fri Oct 28 2016 In the wake of the cold front exiting off the coast, high pressure will build south east into the area in the through the weekend.
Therefore have included a patchy fog mention this morning for the Upper Snake and Upper Highland locations and part of the Eastern Highlands.
A cool northwest flow will prevail across the region today, with high pressure following for the remainder of the week. Some clouds are lingering on the back side of the trough over northeast Utah and southwest Wyoming but the lake effect showers that blossomed overnight have all but dissipated. The clouds will tend to decrease this morning as high pressure continues to move in but temperatures will remain on the cooler side in northwest flow, with maxes running around 10F below seasonal normals over northern Utah and about 5F below climo over southern Utah.
Cold front proggd to drop to our southeast this evening and switch winds around to the north into Thursday. Expect offshore winds to turn more north to northeast today as low pressure begins to develop on a frontal boundary situated well south of the Great Lakes. while mid-lake surface water temps remain in the lower 60s. There is a small chance a few showers could affect areas south of North Point Light tonight as the low pressure area moves through the TN and OH Valleys. Otherwise, a tightening pressure gradient associated with this low pressure area will result in increasing north winds late tonight and Thursday. A strong west/southwest upper jet across Wisconsin becomes a little more southwest as an upper trough begins to dig across the northern and central plains.
/issued 345 AM CDT WED OCT 19 2016/ Late night sfc analysis shows high pressure lingering over the sern CONUS. Water vapor imagery shows ridging aloft extending from the wrn Gulf states across the sern CONUS. Expect a few showers or storms to linger into tonight, especially over our nwrn areas where the influence of the approaching cold front will begin to be felt. likely entering the nwrn zones after daybreak/reaching the US 165 corridor around lunchtime/moving off the lower Acadiana coast late in the afternoon.
1101 AM EDT Wed Oct 19 2016 Currently - An Atlantic pressure ridge extends west southwestward into the southeastern United States and along the Gulf Coast. This ridge is responsible for moderate to fresh northeast breezes across the Florida Keys and surrounding waters. Aloft, the Florida Keys are situated on the western flank of an upper level low and a sharp ridge extends northeastward across the gulf of mexico and southeastern United States. Temperatures have only climbed into the lower 80s this far today, with dew points near 70. Short Term Update - Ridging will continue to dominate our weather this afternoon, with near breezy northeasterly flow. A high pressure system to our north is responsible for moderate to fresh northeast breezes across Florida Keys waters.
748 AM EDT Wed Oct 19 2016 Aviation High pressure will provide dry and mild weather today, then low pressure passing through Ohio Valley will bring some light rain late tonight and Thursday.
627 AM CDT Wed Oct 19 2016 The sfc cold front continues to slide south with a few light showers far west, and will be south of the forecast area by daybreak.
940 AM EDT WED OCT 19 2016 A deep ridge of high pressure will extend across the region through Thursday.
Will see little change in the weather today with high pressure remaining in control. the high will shift out of the area allowing a cold front to approach from the northwest.
Winds will be light and variable overnight, and with the approach of the pre-frontal trough, IFR and LIFR fog will be expected. Weak onshore flow today and tonight, becoming offshore on Thursday first with the passage of the pre- frontal trough then later with the front.
Dense fog has formed along the Highway 84 corridor where a Dense Fog Advisory has been issued and will remain in effect until 9AM. For tonight, clouds will increase across the region ahead of an approaching cold front from the northwest.
A cold front is expected to move into the Metroplex around 07z and into the Waco area around 09z. /ISSUED 413 AM CDT Wed Oct 19 2016/ The weak cold front that moved as far southeast as a Gainesville to Mineral Wells to Cisco line yesterday before stalling this evening has started to lift back to the north.
High pressure will shift over the west coast, bringing mostly dry weather to the region and causing inland temperatures to warm through the second half of the week. High pressure continues to build over the area, drier weather will return from for the remainder of the week.

A dry cold front has pushed through northern Arizona this morning.
Also, a cold front will be moving south across West Central Texas tonight and ending up just north of the I-10 corridor by 12Z. As another cold front approaches, from the north, West Central Texas will have one more day of above normal temperatures. Highs today will be mainly in the upper 80s; that's around 10 degrees warmer than average for this time of year. Another Cold Front and Possible Rain. As another cold front pushes across West Central Texas tonight, showers and thunderstorms may develop along and near that boundary. Cooler with Possible Lingering Morning Showers South. As high pressure and cooler air move into Texas, look for much cooler highs on Thursday, mainly in the lower to mid 70s.
A long wave ridge is currently moving through the Pacific Northwest. This ridge will break to the east of the area this evening, but before it does, it will push a weak front north through the Medford CWA today.
934 AM EDT Wed Oct 19 2016 High pressure ridge will be over region Today, with subsidence limiting potential for showers. Above average temperatures will be expected this afternoon, especially inland, away from the relatively cooler coastal waters. High pressure will be over area waters Today, with continued onshore flow.
1108 AM EDT Wed Oct 19 2016 A cold front will continue to move southward through the area this morning before stalling out in Kentucky. An area of low pressure will move along the front tonight into Thursday.
601 AM CDT Wed Oct 19 2016 A cold frontal boundary will remain draped across the region through early Thursday.
VFR categories will continue into the overnight hours until after 20/06z when a cold front will be moving into parts of Southeast Oklahoma and Southwest Arkansas with a chance of showers and thunderstorms. /issued 341 AM CDT Wed Oct 19 2016/ WV imagery this morning shows upper trof digging esewd across the Four Corners region, with the upper ridge centered over the nrn Gulf Coast beginning to shift ewd in response. Cold front associated with upper low over ern Canada currently draped across srn MO/central OK will be pushed slowly swd today as the trof moves into the Plains. The front will finally get a good swd kick as the trof digs further sewd tonight, and convection will continue to accompany it.
Raised the high temperatures slightly and could see record high temperature at CRP (94). Winds will be light and variable overnight, and with the approach of the pre-frontal trough, IFR and LIFR fog will be expected.
740 AM EDT Wed Oct 19 2016 One more day underneath the upper ridge will result in another unseasonably warm day despite the weakening of the ridge. Digging upper trough/short wave squeezes the ridge out overnight tonight and approaches northwest Georgia during the day Thursday.
1232 PM EDT Wed Oct 19 2016 High pressure will build across the region today and tonight. The high will move east on Thursday.
Deep layer ridging will bring us yet another sunny and unseasonably warm day today.
Did add some patchy fog into the forecast through midday for the higher mountain valleys in Oregon, including near Meacham, Ukiah, Long creek, Seneca and John Day. A warm frontal boundary will move over the CWA this evening bringing increasing moisture. Precipitation totals by daybreak Thursday are expected to range from a few hundreths or less over the Lower Columbia Basin and surrounding Foothills.
Winds will veer around to the northwest at all area terminals by this afternoon ahead of a strong cold front. /issued 210 AM CDT Wed Oct 19 2016/ Another day of near record to record high temperatures are expected by this afternoon across west Texas and southeast New Mexico in zonal flow ahead of the next cold front. This front is expected to push through the forecast area tonight as an upper level trough across the Rockies moves onto the Plains.
Data trends indicate that the largest increase in coverage should occur in the very late afternoon and into the early evening hours, and as a result, the most significant update to the going forecast has been to push the high chance and likely POPs to begin at 21Z instead of 18Z. Front will usher in a cooler and drier airmass with temperatures bearing more of a resemblance to mid-late October.
615 AM CDT WED OCT 19 2016 The cold front has finally slipped south of Lawrenceville as of 200 am and will continue to edge a bit further south before stalling out over far southern Illinois into southern Indiana. Upper trough will sharpen as it moves into the Mississippi Valley on Thursday, helping to boot the cold front and rain off to our east. However, temperatures will recover nicely over the weekend across central Illinois, with more of a zonal flow setting up as the trough shifts to the east. As an upper ridge begins to build across the Plains early in the week, the dry weather pattern will continue over our area.
1014 AM EDT Wed Oct 19 2016 High pressure will build across the region today and tonight. The high will move east on Thursday.
Templer Previous Discussion - A broad trough will remain over the area today. Flow aloft will turn to the northwest this morning as the trough axis moves to the east and an upper ridge moves into the Pacific NW. Skies will clear late this afternoon or tonight as the wave and warm front moves to the east. Upper ridge builds into Montana tonight and Thursday morning with dry and warmer weather.
Cold temperatures across the region this morning with many desert locations at or below freezing. This will mostly affect the outlying areas, but most of the valley should see temperatures at or below freezing. Temperatures Monday night will also be rather chilly, but readings are expected to be a couple of degrees warmer.
