346 PM CDT Tue Oct 18 2016 Upper level analysis places high pressure over eastern TX with anti- cyclonic flow extending over the southeast CONUS. Model are in decent agreement with another cold front moving through the area Wednesday morning through the early afternoon as the upper trough amplifies some breaking down ridge over southeast.
Shallow moisture behind these systems and the low sun angle at this time of year allowed low clouds to persist over much of the area this morning. Meanwhile, a separate trof over Manitoba will shift over northern Ontario on Wed as well. Upper trough is forecast to deepen late this week from the middle conus to the Great Lakes. Conditions will turn cooler across Upper Michigan with daytime temperatures falling a little below normal in the 40s Thu-Sat. Ptype in this area should remain rain with close proximity to warmer Lk Superior waters and as 1000-850mb thickness remain above 1300m and sfc temps stay aoa 38-39F. Mean trough then deepens further over Quebec and the northeast conus through the weekend while nw flow aloft continues across the Great Lakes.
High pressure will over the west coast, bringing mostly dry weather to the region and causing inland temperatures to warm through the second half of the week. As high pressure builds over the area, drier weather will return from mid to late week with temperatures warming to about 10 degrees above normal over the interior.
Cold front with a little more teeth to it will hold off to our northwest.
156 PM CDT Tue Oct 18 2016 A cold front that pushed through this morning is currently stretched along the Pecos River. Temperatures ahead of the front range from the upper 80's to the mid 90's this afternoon while slightly cooler conditions have settled in behind the boundary. An UA trough will move across the West today and into the Plains Wednesday.
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. As high pressure builds over the area, drier weather will return from mid to late week with temperatures warming to about 10 degrees above normal over the interior.
846 AM EDT WED AUG 10 2016 Low pressure system to the West will continue to move further to the West Today. Circulation around this low will continue to advect moisture North into the region Today, with a band of showers from this system possibly affecting Western counties Today.
930 AM EDT WED AUG 10 2016 Broad area of low pressure along the Florida panhandle continues to induce low level SE winds across much of the area. Chattanooga Airport, TN 92 75 93 74 / 30 30 40 20 Knoxville McGhee Tyson Airport, TN 91 72 91 73 / 20 20 40 20 Oak Ridge, TN 91 72 92 73 / 20 20 40 20 Tri Cities Airport, TN 89 70 90 70 / 30 20 40 20.
1047 AM EDT WED AUG 10 2016 High pressure off the east coast will remain there through the weekend.
434 AM PDT Wed Aug 10 2016 A deep and slow moving low pressure system will exit the area today, with a decreasing trend of clouds and showers.
Otherwise, the previous forecast still on track as waves of energy will cross the area, moving along the northern periphery of the Eastern Conus ridge.
Temperatures will be warmer today, but still 10 to 15 degrees below normal. Upper level low over Idaho panhandle will continue to move off to the northeast today. A trailing trough line extending back through northern California means that the southeast part of the forecast area will remain under southwest flow aloft with a little bit of upper level divergence, and a little bit of monsoon moisture nearby. This trough line passes to the east tonight, leaving the area in dry northwest flow for Thursday. Temperatures will slowly warm as the influence of the upper low drifts away.
Moisture will temporarily return to the area today and linger into Thursday as a Pacific trough slowly crosses the region.
Building high pressure will result in a warming trend over the next several days with inland temperatures reaching the triple digits for the weekend. Early morning water vapor imagery showed an upper trough spiraling over the Pacific Northwest. This trough will make an eastward shift and strong high pressure will move in its wake causing 500mb heights to build through the weekend. Building high pressure will also reinforce the development of coastal stratus with blue skies peaking through scattering clouds each afternoon. Before the trough makes a complete exit of the region, it will spin band of vorticity across Northwest California this afternoon.
with most coverage confined to the higher terrain of southeast OK and northwest AR. /Issued 325 AM CDT WED AUG 10 2016/ The upper level ridge will continue to slowly strengthen today and into Thursday.
731 AM EDT WED AUG 10 2016 Aviation High pressure centered over Michigan will keep the weather mainly dry into tonight. The pattern starts to change Thursday as a slow moving cold front nears from the northwest.
Short Term Update - Broad surface ridging will remain near the Florida Keys through this afternoon. With day time heating, conditions are expected to be conducive for isolated shower and thunderstorm development along an island cloud line, despite continued warmer and drier air just above the surface. A light mostly easterly flow is expected to develop across Keys waters due to a nearby pressure ridge.
A broad area of high pressure sits over the east coast, extending over the Florida peninsula. At the surface, an area of low pressure continues to shift slowly westward across the north- central Gulf coast with an area of high pressure centered to our northeast over the western Atlantic. We will still likely have some influence from the low to our west, but with high pressure building back over the area, we should start to sea more sea breeze activity as well. The highest rain chances will likely be across the interior where the west and east coast sea breezes provide the greatest convergence. High pressure will build over the waters and remain in place for the next several days, keeping a mainly southeast wind flow across the region, with the afternoon sea breeze turning winds onshore each afternoon.
Clouds will give way to partly sunny conditions during afternoon as high pressure builds offshore.
551 AM MDT WED AUG 10 2016 Pretty active in the short term with fire weather issues today and then rain chances with a cold front moving into the area tonight into Thursday. Cold front extends south from the low to just west of Casper, to near Rock Springs to just south of Salt Lake City.
High pressure building over the Pacific Northwest will bring a warming trend and drier weather through the rest of the week. Upper low located over southern Alberta this morning with the associated trough still lingering across the Pacific Northwest. As that system continues to move away today, high pressure will begin to take hold, meaning clearing skies and dry and warming conditions. Expect afternoon temperatures today to be 5 to 10 degrees warmer than yesterday, getting to the upper 70s to mid 80s inland. Areas which clear out sooner this morning will see more heating and thus the warmer end of the temperature spectrum.
847 AM PDT WED AUG 10 2016 Fair and mild weather will continue through Thursday as a trough of low pressure moves through the West.
913 AM EDT WED AUG 10 2016 Upper ridge to the east through the week.
Short wave moving through the broad trof over the Wrn states may trigger isolated convection near the Lassen Park area today. JHM This will result in a bit cooler temperatures as far inland as the Sacramento region.
Upper high will strengthen over the region in advance of storm system approaching from the northern plains. Heat index values this morning are in the low to mid 90s. Temperatures tomorrow will be the highest of the week with some 100 degree readings possible.
815 AM EDT WED AUG 10 2016 High pressure off the east coast will remain there through the weekend.
951 AM EDT WED AUG 10 2016 Slightly more complicated forecast today as the influence from the low/mid level low along the Gulf Coast continues to wane. High pressure building in from the western Atlantic has weakened/backed winds in the lowest several thousand feet.
Upper low over NW Montana has it associated rain/thunderstorm shield mainly north of the Canadian border this morning. An inverted trough over the area is expected to push east and allow dry NW winds to help scour out the lower clouds today. Clouds are expected to move back in tonight as the upper low moves across southern Sask. TFJ Upper low swinging into western Montana early this morning with jet pushing lingering thunderstorms to the edges of the cwa. Cold front will sweep into North Dakota this morning with airmass drying. As the low lifts toward southern Saskatchewan today could see a few storms wrap around into north central Montana this evening. Northwest flow behind the upper low will bring cooler air into the state.
VFR conditions will prevail this TAF period with high pressure aloft. Upper high will strengthen over the region in advance of storm system approaching from the northern plains. Heat index values this morning are in the low to mid 90s. Temperatures tomorrow will be the highest of the week with some 100 degree readings possible.
Seasonable weather conditions will continue today as a broad trough remains over the West Coast. A gradual warming trend is then expected for late week and into the weekend as high pressure builds over the region. A broad mid/upper level trough remains stretched across much of the West Coast this morning as the parent low continues to move into the Great Basin. As the aforementioned trough shifts further away from the West Coast, high pressure will begin to develop over the eastern Pacific through late week.
(Issued 141 AM CDT WED AUG 10 2016) As has been progged the past couple of days, an upper ridge axis is now in place across the TN valley east through the mid Atlantic coast. The upper low in the northern Gulf was migrating westward with one lobe of vorticity in GA and eastern AL and another stronger wave/circulation pushing into northeast FL. At the surface, the low pressure center was now in the Jackson/Meridian MS area with a tightening gradient increasing southeast flow across eastern AL into GA.
Currently, low pressure is situated over the Red River Valley with pressure rises behind the low tracking across central ND. The southwest may well escape the low stratus today. High pressure over the area early tonight slides into Minnesota by 12 UTC Monday. Southeast flow continues on Monday and Monday night with increasing low level moisture as an upper level ridge tracks across the northern plains.
255 AM EDT SUN OCT 23 2016 High pressure will continue to build over the SE US today and tonight. This high will weaken as shift south of the area on Monday, in advance of a dry cold front moving through the area Monday evening. In the wake of the upper low lifting northeast into eastern Canada, rising heights aloft and associated strong subsidence warming will allow for wall-to-wall sunshine. Modest CAA Monday evening/night on the leading edge of Canadian high pressure building into the area from the NW will support lows in the lower 40s north to mid/upper 40s south.
400 AM CDT SUN OCT 23 2016 (Today and Tonight) A weak upper level low will track across West Central Texas today, then shift east of the area overnight. The main impact that this low will have on the area is an increase in mid to upper level cloud cover, especially across the southern half of the region. Temperatures this afternoon will range from the upper 70s across the southern portions of the area, where more cloud cover is expected, to the low 80s across much of the rest of the area.
Upper level ridge over the Intermountain West today will shift over the Rockies Mountains on Monday in response to deepening upper level trough off the west coast.
338 AM EDT Sun Oct 23 2016 High pressure in control on today. A weak, moisture-starved cold front crosses early Monday morning, with gusty winds in the mountains and possibly an isolated shower. Issued frost advisory far south where surface ridging has allowed decoupling.
1121 PM MDT Sat Oct 22 2016 An upper ridge axis moved to the east, opening the area to increasing southwest flow aloft. Sunday and Sunday night the broad trough off the west coast will continue deepening and moving slowly east. As this trough moves east precipitation should spread across the entire forecast area late Monday night.
646 AM EDT Sun Oct 23 2016 High pressure today. Weak, moisture-starved cold front crosses early Monday morning, with gusty winds in the mountains and possibly an isolated shower. A weak cold front approaches from the west tonight. High pressure builds overhead Monday night and will make for a clear and chilly night with frost possible across the Northern Forecast Area from the Ohio Valley to the Eastern West Virginia Mountains. It is possible we could even see some freezing fog in some of the sheltered mountain valleys.
250 AM MDT Sun Oct 23 2016 The cold front is mostly through the forecast area early this morning. Winds out west in the high country should pick up and veer to the southwest through the late morning as the front shifts east a bit into the plains. Temperatures will be cooler today and moisture higher tho, so fire weather concerns should remain minimal. Monday will be warmer as the thermal ridge moves overhead in southwest flow aloft. Increasing Pacific moisture from the southwest will bring showers and perhaps an isolated t-storm or two to the high country on Monday as well.
305 AM CDT Sun Oct 23 2016 A minor upper level trough was rounding the upper level ridge axis across the southern plains. The upper trough was moving into western MN and will dig and amplify as it moves into New England Tonight. The upper level ridge axis will amplify across the plains tonight as a more amplified upper trough moves onshore across the western US late Tonight. The front will come through dry as the broad upper ridge will continue across the southern and central plains. Highs should warm into the mid 70s across the southern half of the CWA and will be a bit cooler across the northern counties with highs in the lower 70s. Lows will be a bit cooler but still remain above seasonal norms, with lower to mid 40s.
403 AM MDT Sun Oct 23 2016 Lighter winds are expected today as the upper ridge rebuilds over the region. Cold front is making progress southward through east central Colorado and should move through all of southeast CO by 14Z. Winds will shift around from the east behind the front across the plains with temperatures around 10 degrees or so cooler than yesterday. Low temperatures should be somewhat warmer out west given increasing high cloudiness.
214 AM EDT Sun Oct 23 2016 Strong low pressure will move slowly north from Maine to Southeast Canada through Sunday.
and deep low pressure over eastern Quebec today and tonight. The clipper's cold front will cross the region early Monday, followed by cool high pressure for mid-week. A low pressure system will approach from the west late in the week. At 300 AM, winds were still strong across the higher elevations and the warmer waters, with the strongest winds still at gale force over Tangier Sound. There will be some low level moisture advection that will increase dewpoints, so min temps will be from the low 40s at higher elevations and sheltered valleys to near 50 in the urban corridors to the Chesapeake. On Monday, the clipper's cold front will cross the forecast area with additional cold air advection.
400 AM EDT Sun Oct 23 2016 High pressure today. Weak, moisture-starved cold front crosses early Monday morning, with gusty winds in the mountains and possibly an isolated shower. A weak cold front approaches from the west tonight. High pressure builds overhead Monday night and will make for a clear and chilly night with frost possible across the Northern Forecast Area from the Ohio Valley to the Eastern West Virginia Mountains. It is possible we could even see some freezing fog in some of the sheltered mountain valleys.
Reinforcing high pressure in wake of a cold front Monday night will maintain dry Autumn weather much of the upcoming week.
415 AM MDT Sun Oct 23 2016 The large upper level ridge will amplify across Colorado through tonight in response to a deep upper low dropping south toward the Pacific Northwest. At the surface, a weak cold front was pushing across the plains early this morning. Cooler high pressure will continue to build southward through the day and will result in cooler but still above normal temperatures across the plains. Abundant upper level ridging will dominate the bulk of Colorado weather this week. Early in the week, the ridge axis will be sliding eastward ahead of a weakening trough ejecting across the desert southwest.
423 AM CDT Sun Oct 23 2016 Today through tonight, Overall, expect continued dry weather with a warming trend for the ArkLaMiss early this week as forecast models are in agreement on rebuilding the upper level ridge across the southern tier of the CONUS.
Cold high pressure moving across eastern Montana this morning. Upper ridge building over the state will begin to pump warmer air northward.
Afternoon high temps will be a little warmer than yesterday, mainly in the mid to upper 70s. The quiet and dry wx pattern will continue thru this period as high pressure dominates the area.
302 AM CDT Sun Oct 23 2016 An area of low pressure along the North Dakota and Minnesota border will move quickly into southern Wisconsin this afternoon and into southeast lower Michigan by early evening. We continue to have the highest POPs over far northern Minnesota this morning shifting them into far northern Wisconsin this afternoon. Expect highs from the upper forties along the International Border to the lower to middle fifties south. High pressure will build in tonight with the region remaining dry. High pressure will keep the area dry through Monday with highs from the lower to middle forties north to lower fifties south. Monday night finds upper level and surface ridging covering the area.
437 AM EDT Sun Oct 23 2016 Strong low pressure system will part to the north, bringing an end to rain and snow showers today. Some lingering snow showers over the higher terrain could persist into this afternoon.
140 AM EDT Sun Oct 23 2016 High pressure centered to the south will keep dry weather over the region tonight.
321 AM EDT Sun Oct 23 2016 A quick moving low pressure will bring rain showers mostly north of Pennsylvania and Ohio turnpikes Sunday night. Highs Sunday should reach low 60s by afternoon, mid to upper 50s in the high terrain and across the north. Rain will initially hold off until after sunset tonight, but will quickly spread to areas north of I-80 and eventually into the ridges overnight into Monday morning. Gusty southwesterly winds will continue overnight as a strong low-level jet streak will accompany the passage of the low. Cool northwest flow will re-establish in the wake of the clipper and associated cold front. Can't completely rule out lake-enhanced showers across the north Monday, as the cooler air moves over the relatively warm Lake Erie waters.
Cloud cover will gradually increase later today as the upper low approaches from the west with high temperatures remaining near normal to slightly below normal.
156 AM EDT Sun Oct 23 2016 Dry, high pressure will settle over the region Sunday. Temperatures will be warmer Monday with some air mass modification. Another cold front will move through the area Monday evening with a re-enforcing shot of cool air through Midweek. Today, an upper level trough over New England will be moving northeast while a ridge builds over the Midwest and Gulf coast states. Guidance temperatures appear on track with maximum temperatures in the lower 70s. Overnight temperatures Sunday night should be warmer than the previous night due to a relatively strong low level jet. Another weak cold front will approach the region late Monday. Cooler air mass from the Upper Midwest will be building southeast behind the front.
This disturbance will move northeast today allowing an upper ridge to build over the western U. The ridge will cause temperatures to be around 10 degrees above normal but still below record highs for this time of year which is around 90 degrees. A couple of troughs will round the northern periphery of the high the next seven days but will be too weak and too far north to push a front into our CWA.
247 AM EDT SUN OCT 23 2016 High pressure will continue to build over the SE US today and tonight. This high will weaken as shift south of the area on Monday, in advance of a dry cold front moving through the area Monday evening. In the wake of the upper low lifting northeast into eastern Canada, rising heights aloft and associated strong subsidence warming will allow for wall-to-wall sunshine. Modest CAA Monday evening/night on the leading edge of Canadian high pressure building into the area from the NW will support lows in the lower 40s north to mid/upper 40s south. An upper level trough will exit the east coast early this week and a dry cold font will pass through Monday night leaving central NC on the front side of an upper level ridge.
306 AM CDT Sun Oct 23 2016 WV imagery shows the upper ridge gaining ground on the srn CONUS this morning in the wake of the departing trof over the E Coast. Weak disturbance moving around the wrn periphery of the ridge bringing some cirrus to our region, and this will continue throughout today and into Tue.
428 AM EDT Sun Oct 23 2016 A strong low pressure system over eastern Canada will keep windy and cool conditions over the region today.
/EC/ Today through tonight, Overall, expect continued dry weather with a warming trend for the ArkLaMiss early this week as forecast models are in agreement on rebuilding the upper level ridge across the southern tier of the CONUS.
348 AM CDT Sun Oct 23 2016 High confidence of a dry forecast in the short term as a reinforcing high pressure system moves southeast in the wake of a cold frontal passage tonight.
Clear Skies and Cool temps on track with High pressure NW of the region and widespread lows still expected in the lower/middle 40s inland and near 50 along the coast. High pressure settles down over the NE FL/SE GA region with sunny skies and light North to Northeast winds. High pressure ridge remains across the region but weakens slightly and still expect good radiational cooling conditions under clear skies and light winds. Expect another round of Min Temps in the lower/middle 40s inland and near 50 closer to the coast. High pressure will continue to build in on Monday and temps will continue to moderate with max temps checking in just a little above normal ahead of an approaching backdoor cold front.
313 AM EDT Sun Oct 23 2016 High pressure will prevail across the southeast today. A dry cold front will move through on Monday. with strong high pressure building back in from the north through the middle of the week.
217 AM EDT Sun Oct 23 2016 High pressure passes south of the area overnight and Sunday. Weak, moisture-starved cold front crosses Sunday night, with gusty winds in the mountains. Issued frost advisory far south where surface ridging has allowed decoupling.
255 AM CDT Sun Oct 23 2016 We are seeing a warmer start this morning than the last couple around the Ozarks. Temperatures ranged from as warm as the lower 60s out in Pittsburg, KS to 51 in Osage Beach at the time of writing this discussion. A warm southerly flow has taken shape across the region and should continue to bring warmer air into the region. Sky conditions will be mostly clear again today/tonight as a ridge of high pressure remains in control of our weather.
