1141 AM EDT Tue Nov 1 2016 Late morning surface analysis depicts strong high pressure (1034 millibars) centered over northeastern Quebec, ridging southward along the New England and Mid-Atlantic coasts. strong ridging is centered directly over our region. Lows tonight will be warmer, with mid to upper 60s expected at most locations. Strong high pressure currently aligned along the New England and Mid-Atlantic coasts will expand southward into our region this afternoon, tightening our local pressure gradient and causing northeasterly winds to strengthen to near 15 knots. Winds and seas will begin to gradually decrease by Wednesday night as high pressure weakens and pushes southward, causing our local pressure gradient to loosen.
An upper level ridge of high pressure will remain in control of the weather today. Surface winds will increase and become gusty out of the south to southwest as low pressure slowly moves east across southern Kansas. It looks like record high temperatures are in serious jeopardy today as progged 850 mb temperatures support high temperatures in the lower 80s.
743 AM EDT Tue Nov 1 2016 High pressure centered over New England will move off the coast this afternoon. allowing a warm front to lift north across the area. A low pressure system will move across the Lower Lakes Wednesday night.
Dry weather conditions return region-wide tonight and will continue through the remainder of the workweek as high pressure builds aloft.
728 AM EDT Tue Nov 1 2016 Aviation A southwest flow of mild air will continue today as a cold front approaches from the northwest. Meanwhile a wave of low pressure will ride along this front and move into Michigan on Wednesday.
Weak upper level trough will continue to track across the Great Basin, mainly in Nevada and Utah today. Upper level ridging builds into the area on Wednesday and temperatures aloft warm. The showers were associated with an upper trough, with an upper low being the primary focus for the activity which was located in northern California. The low center will remain to our south as it moves across Nevada today, although the showers associated with the weaker northern portion of the trough will persist this morning. The showers will taper off this afternoon and end this evening as the trough moves to our east. An upper ridge will fold into the region tonight through Wednesday for dry conditions and decreasing clouds. Mostly clear skies will accompany the ridge on Wednesday. High temperatures will be near normal today and 4-8 degrees warmer on Wednesday.
806 AM EDT Tue Nov 1 2016 The lower troposphere has largely remained void of low cloud across southeastern Michigan overnight. Model data supports some slight southeastward advection of the low level moisture, filling in and around a frontal boundary that will push southward and stall in vicinity of the Saginaw Valley. Many areas, particularly west of the glacial ridge will be nearing average highs for the date (low 50s) by 12z. Upper trough will sweep through Wednesday night, likely leading to an uptick in shower coverage before sweeping the front east.
740 AM EDT Tue Nov 1 2016 Ridging aloft will continue through the short term.
739 AM EDT Tue Nov 1 2016 High pressure will extend across the Middle Atlantic and Carolinas through tonight, followed by the passage of a warm front early Wednesday.
Expect a partly sunny day along with slightly cooler temperatures. Temperatures will be a little cooler today but weak low level downslope gradients will keeps highs around 60 degrees. Wednesday will be dry as amplified ridging noses into western Montana.
930 AM PDT Tue Nov 1 2016 Another cooler than normal day will occur today under onshore flow and areas of morning low clouds, mainly north of San Diego County. Offshore flow will develop Wednesday and bring warmer weather with mostly clear skies.
922 AM EDT Tue Nov 1 2016 High pressure will crest over the region this morning before sliding offshore. A warm front will lift into the region from the southwest tonight and be quickly followed by a cold front on Wednesday. The cold front will then stall over southern New England Wednesday night.
928 AM EDT Tue Nov 1 2016 High pressure centered over New England will move off the coast this afternoon. allowing a warm front to lift north across the area. A low pressure system will move across the Lower Lakes Wednesday night.
1208 PM EDT Tue Nov 1 2016 High pressure centered over New England will move off the coast this afternoon. allowing a warm front to lift north across the area. A low pressure system will move across the Lower Lakes Wednesday night.
1017 AM EDT Tue Nov 1 2016 High pressure to the north of the region will maintain east to northeast flow over South Florida today. /issued 807 AM EDT Tue Nov 1 2016/ High pressure to the north will maintain NE winds this morning, strengthening to 11-15 KT by 01/1500Z with high gusts at times.
1253 PM EDT Tue Nov 1 2016 Hydro A southwest flow of mild air will continue today as a cold front approaches from the northwest. Meanwhile a wave of low pressure will ride along this front and move into Michigan on Wednesday.
936 AM EDT Tue Nov 1 2016 High pressure ridges will ridge into the region from the north through Wednesday night.
1032 AM EDT Tue Nov 1 2016 High pressure will move east of the region today. A warm front will lift across the region tonight, followed by a cold front on Wednesday.
/issued 440 AM CDT Tue Nov 1 2016/ SHORT TERM (Today through Wednesday): Water vapor imagery shows a weakening 500mb low over Central Texas with mid level ridging over the Eastern Gulf of Mexico this morning. Due to the elevated sea heights (which most is east-southeast swell), have decided to extend the coastal flood statement to cover the higher tide cycle this evening.
710 AM EDT Tue Nov 1 2016 A warm front pushes through the area this morning, with warm afternoons today and Wednesday.
807 AM EDT Tue Nov 1 2016 High pressure to the north will maintain NE winds this morning, strengthening to 11-15 KT by 01/1500Z with high gusts at times.
09z Water vapor imagery shows upper low near the Hudson Bay propagating eastward. With the ridge closing in on IA, the pressure gradient will be relaxing throughout the day.
148 PM PST Wed Mar 8 2017 High pressure and continued weak offshore flow will persist through Thursday with above normal high temperatures.
However, persistent cloud cover should keep temperatures down in the mid 60s to lower 70s instead of being 5 degrees warmer as predicted by some of the shorter term hi-res model blends. Cigs will lower into IFR overnight as moisture remains and the low levels begin to cool. With the cold front from yesterday now south of the CWA, 850 mb low level flow is overrunning the boundary and resulting in isentropic lifting over much of the CWA.
Chattanooga Airport, TN 41 73 52 69 / 0 0 40 40 Knoxville McGhee Tyson Airport, TN 39 69 51 62 / 0 0 40 40 Oak Ridge, TN 39 71 51 64 / 0 0 40 40 Tri Cities Airport, TN 34 68 42 61 / 0 0 30 40.
317 PM CST Wed Mar 8 2017 High pressure over the Mid South this afternoon will slide east tonight with return flow setting up over the area. This should provide for a warmer night with lows mainly in the 40s. Most locations will see high temperatures in the lower to middle 70s.
1155 AM CST Wed Mar 8 2017 Very dry conditions will gain dominate the region with high pressure firmly in control.
Afternoon highs should range from the lower 60s across southern IN and northern KY to the lower-mid 60s across southern Kentucky. Also, went below guidance for dew points this afternoon, taking them to the lower 20s. Tomorrow the high will slip off to the southeast as a cold front approaches from the north.
HRRR holds on to the high wind potential a little longer than 23z in the east while the RAP tends to suggest warning winds would for the most part be done. So expect the winds to diminish as the evening wears on with high pressure nudging closer. The ridge axis is proggd to be across the state in a NW/se oriented fashion around 06z.
Cigs will lower into IFR overnight as moisture remains and the low levels begin to cool. With the cold front from yesterday now south of the CWA, 850 mb low level flow is overrunning the boundary and resulting in isentropic lifting over much of the CWA.
Today Through Thursday Night High pressure will bring very dry air today. As the high shifts to the east tonight and Thursday, clouds will gradually increase from the southwest. As the period comes to a close, a cold front will approach from the north.
Thursday night a system will move through bringing chances for rain changing over to snow with no accumulation and some cooler air behind it.
Some minor disturbances will pass over the area as a weak low pressure system moves eastward from the Baja coast.
/issued 257 AM EST Wed Mar 8 2017/ High pressure is weakening as progged. The high weakened ahead of an approaching cold front, currently moving into the Florida panhandle this morning. This high will keep the weather mostly quiet and dry through the first part of the weekend, barring some periodic isolated shower activity.
This will result in the possibility that places like Red Lodge, Nye and Fishtail will be quite a bit warmer at times than locations such as Billings.
314 PM CST Wed Mar 8 2017 Subjective analysis of 12z upper-air data and current water vapor imagery indicate a broad mid-level trough from the vicinity of Hudson Bay south through the Great Lakes with a west-northwest flow regime present upstream across the western CONUS.
1249 PM EST Wed Mar 8 2017 A cold front will push off the coast this afternoon.
251 PM MST Wed Mar 8 2017 Temperatures across the region warmed quite a bit compared to yesterday with 50s across many of the higher valley locations and temps near to just a bit above 60 degrees in the lower valleys of southeast Utah and west-central and southwest Colorado. Expect a similar trend with warmer temperatures Thursday as a dry northwesterly flow remains overhead with high pressure across the western states.
A cold front is very evident on satellite and extends southwest along the eastern seaboard, through southeast Georgia and through the western Florida panhandle. The highest rain chances will be along the Nature Coast and inland areas, but still only looking at a 20 percent chance of showers. A weak cold front will approach the waters later this morning with a slight chance of showers possible primarily over the northern waters off the Nature Coast. High pressure builds into the gulf and will influence the weather through the end of the week.
Temperatures will be 5 to 10 degrees warmer today under mostly sunny to partly cloudy skies as a subtle warming trend begins. The current satellite water vapor image is showing a strong low pressure system centered over northern Ontario and a weak low over the Pacific just west of the Baja Peninsula.
1112 AM EST Wed Mar 8 2017 Dry high pressure moving into the forecast area from the west will be over the area late tonight and early Thursday. The high will move off the southeast coast Thursday afternoon.
Some of these clouds will continue to creep north toward the I-20 corridor this afternoon, but temperatures are still expected to climb into the lower to mid 70s areawide.
The deepening closed upper low is currently parked over northwest Ontario near Hudson Bay as of 815Z. Embedded pieces of energy will continue to rotate around the upper low and across the forecast are through the morning. Cold, dry high pressure will cover the forecast area for the rest of tonight and Thursday.
South of the UT/ID border region, a continuation of building heights will promote steadily warming temps through the low/mid levels, and with deep mixing potential through at least H7 will see good response driving max Temps 5 to 10 degrees above climo today.
318 PM CST Wed Mar 8 2017 (Tonight and Thursday) Moisture return and warmer weather has quickly returned to the area today. Dewpoint values as of 2 PM this afternoon range from the low 50s to around 60(KJCT) across the CWA. Low clouds will also return to the area, along with the potential for patchy fog developing after midnight, mainly southeast of a Brownwood to Sonora line where the highest moisture content will reside. The warmer temperatures will be along and north of a San Angelo to Clyde line where afternoon sun is expected to aid in warming.
Also, best hourly forecast tools indicate that rain and/or freezing rain may mix in with the snow over these advisory areas. Arctic high pressure will keep the NE half cold and mainly dry.
429 PM EST Wed Mar 8 2017 Dry high pressure moving into the forecast area from the west will be over the area late tonight and early Thursday. The high will move off the southeast coast Thursday afternoon.
Highs on Thursday will be in the 40s in southern Lower Michigan to the lower 50s south of Route 30.
231 PM CST Wed Mar 8 2017 One more mild day ahead as high pressure builds into the Deep South, opening the door for SW return flow into the Lower Ohio Valley. Temps will be a few degrees warmer than today, with most locations reaching the lower/mid 70s. Fire weather concerns are alleviated as the low-level RH will recover and the winds will remain fairly marginal. Pattern change really kicks in Thu night/Fri as a strong cold front moves through.
1130 AM EST Wed Mar 8 2017 A cold front will move across the region this morning. A broad trough of low pressure will settle into the northeast tonight and will persist over the area on Thursday.
The weak easterly synoptic flow is being supported by high pressure centered over the Lower Mississippi Valley, which will shift farther east by Thursday, reorienting pressure over the Gulf such that winds will shift to southeast. Ahead of that, however, mid level energy associated with an inverted trough over Baja California will break off and move east across the Southwestern United States Thursday morning.
A weak cold front is lingering over southeast portions of the region. As a cold front moves through the area today, rain chances will gradually decrease from west to east as the strongest dynamics remain well to the north with low instability across the area. High temperatures today are expected to range from the lower 70s across the northwest to near 80 across the far southeast big bend.
However, radar showed some light echos over the mountains indicating light precipitation continuing over the high terrain.
At the surface, a cold front is located along the Eastern Seaboard with high pressure across the Southeastern U. Further to the northwest, there is a cold front stretching across the Great Lakes region into the Central Plains. Warm air advection will take over in the low levels with high temperatures rising into the mid 60s to low 70s.
A cold front that pushed through the area yesterday is slowly drifing northward as a warm front. Am expecting this trend to continue as a warm front slowly moves north with increasing dewpoints in its wake.
246 PM EST Wed Mar 8 2017 Dry high pressure moving into the forecast area from the west will be over the area late tonight and early Thursday. The high will move off the southeast coast Thursday afternoon.
The snow associated with this moisture will increase in intensity later this evening and cause significant snow fall in the higher terrain and some impactful snow in the valleys of western Montana.
A period of dry weather is expected through the at least the weekend with near normal to slightly warmer than normal temperatures. Thus, expecting the ridge aloft to aid in warming temperatures with much of the region forecast to warm into the low/mid 60s at the coast to mid 60s to lower 70s inland. Mid and high level clouds continue to stream over the region with a flat upper level ridge. Given the position of the ridge and jet stream the storm track will mainly be over the Pac NW.
239 PM EST Wed Mar 8 2017 High pressure extends across the western Atlantic through the central Florida Peninsula, with a 3 millbar gradient from the center of the ridge through Havana. East winds have eased to moderate speeds, although a 1535Z ASCAT pass indicated winds up to near 20 knots over the offshore Straits south of the Lower Keys.
High pressure will remain over the Mid South today.
331 PM CST Wed Mar 8 2017 High pressure continues to control conditions over northern Alabama and Mississippi.
357 PM CST Wed Mar 8 2017 A fairly quiet night in store for the forecast area as high pressure shifts to the east overnight.
Skies have cleared across the Mid-State, and by early this morning an area of cool high pressure had settled in over the Tennessee Valley. Highs today will be mainly in the lower to middle 60s, while highs on Thursday are expected to soar into the lower and middle 70s in most areas west of the Cumberland Plateau. As we head into late week, a big-n-cold 1050mb high pressure area over central Canada starts to plow southward, as an upper ridge buckles over the western U.
The high wind warning will remain in effect for all areas through 7 PM. Polar cyclone spinning over Hudson Bay this afternoon is progged to become a stable feature for the balance of the forecast period. 850mb temperatures will settle between -5C and -10C this evening as the wave overhead drags the cooler profile southward. Shear max coming onshore in the Pac NW this afternoon will race across the Lower Peninsula on Thursday, the attendant tightening of the height gradient is modeled to elicit a decent but short-lived shot of isentropic ascent and mid-level fgen.
1124 AM EST Wed Mar 8 2017 A steep pressure difference between a storm over south-central Canada and high pressure over the Tennessee Valley will lead to strong and gusty winds and mild conditions today.
138 PM EST Wed Mar 8 2017 Dry and windy conditions are expected today as strong high pressure moves in.
122 PM EST Wed Mar 8 2017 A steep pressure difference between a storm over south-central Canada and high pressure over the Tennessee Valley will lead to strong and gusty winds and mild conditions today into tonight.
The remaining showers and a few thunderstorms generally are moving to the northeast as winds in the lower half of the atmosphere are from the southwest. /issued 242 PM CDT FRI AUG 19 2016/ Overall, a typical summer weather regime will persist into the weekend with a Bermuda ridge extending from the the western Atlantic into the northern Gulf of Mexico.
1000 PM EDT FRI AUG 19 2016 A trough of low pressure will bring unsettled weather to the area through Saturday, before dissipating Saturday night.
Farther south still potential for some light rain mainly south of I-94 as upper trough/wave rotate through the north central US. A secondary cold front is descending into the area through southern Manitoba and will provide that bit of focus needed for showers to develop. the mid level H5 trof axis should shift into western Minnesota allowing for some drying aloft over the eastern Dakotas. H5 ridging will steadily build in aloft during the day. This period starts off with an upper level trough exiting the area and cool high pressure settling in at the surface. Expecting lows in the lower 40s in some areas.
1148 PM CDT FRI AUG 19 2016 Early afternoon surface analysis indicated a cold front from northern IA into northern KS. The upper air analysis did indicate that the better flow was trailing the cold front limiting effective shear, and the orientation of the cold from northeast to southwest along the deep-layer shear vector suggest any organization to the thunderstorms will likely be linear. We will also see a stronger cold front associated with the stronger trough that will bring in much cooler and drier air, along with gusty northwest winds overnight. A touch of fall is likely on Saturday night with some upper 40s possible in the better radiational cooling locations, but everyone should see overnight temperatures drop into at least the lower to mid 50s.
As expected, a large area of convection has formed across Kansas this afternoon ahead of an approaching cold front. Short term guidance suggests that the low level jet should increase considerably late this evening across the western portions of the forecast area, with associated ascent interacting with the remains of the MCS as it moves into the region. Meanwhile thunderstorms will increase across Kansas later this afternoon in advance of an approaching cold front. These storms will push into the Ozarks region tonight as the front pushes steadily southeastward in association with a pronounced upper level trough swinging into the central U. Showers and thunderstorms will persist into Saturday morning as the cold front makes it way across the region.
This resulted in the lowering of pcpn chances across much of the mid state during the evening and even into the overnight hrs, with increasing pops across locations approaching the TN River Valley by 20/12Z. Weak ridging influences across the southern Appalachians will continue there previous trend of usher in gulf moisture to the mid state region thru tonight.
In addition, a solid line of showers and thunderstorms ahead of an approaching cold front is pushing into Southwest Missouri. Temperatures will remain seasonably warm tonight with lows Saturday morning in the low to mid 70s. On Saturday, a cold front will move out of the central U. The cold front will move into the forecast area sometime Saturday night with more thunderstorms expected to more across the region.
940 PM CDT FRI AUG 19 2016 The cold front moving across northwest Oklahoma is forecast to continue its southeastward advance overnight. Thunderstorms are still expected to impacted the region later tonight as a cold front, with an accompanying wind shift from the north, moves in from the north.
Scattered convection along cold front across southern KS will spread south this evening into northeast OK and eventuall northwest AR/southeast OK later tonight. Cold front stretching from north central KS into northwest OK will be driven south tonight by potent upper wave moving across the Dakotas and should arrive in northeast OK in 03z-06z range. Cooler and drier air will begin to spread south during the day behind the front, which will eventually push south of the Red River by evening.
937 PM EDT Fri Aug 19 2016 A weak residual boundary just south of the area will drop southeast tonight as weak high pressure slides in from the west overnight into Saturday.
Main upper level low pressure trough to our west showing up real well on satellite late this afternoon. Strong upper divergence in advance of the trough was bringing a large area of showers to central and north central SD. This upper trough will continue to move east through tonight across SD and into MN by Saturday morning. The models then all show another weak short wave trough coming across the region from the northwest Saturday into early Saturday evening. The lift from this trough along with surface heating instability in the cool air should bring redevelopment of scattered showers and isolated storms across mainly our eastern cwa on Saturday.
Convection will continue to sag south into northeast OK with the cold front. The cold front extends from central IA/KS into northwest OK. as upper trough moves into the central Plains tonight.
701 PM EDT FRI AUG 19 2016 A trough of low pressure will bring unsettled weather to the area through Saturday, before dissipating Saturday night.
High pressure will move into the forecast area tonight and tomorrow, resulting in a drying trend. A cold front has pushed through central Utah and is currently draped near a Milford to Green River line. With the trough responsible for the cold front now tracking into the northern Great Plains state, high pressure associated with colder air has set up western Wyoming allowing the MSLP gradient to tighten over southwest Wyoming.
