Otherwise dry weather will continue for the rest of the area with passing high clouds as weak high pressure remains in place across the Great Lakes.
120 PM EDT Thu Oct 27 2016 Aviation Rain and snow showers will be ending this morning with fair weather through Friday as high pressure builds in.
252 PM CDT Thu Oct 27 2016 Skies are partly cloudy over much of the forecast area this afternoon with temperatures ranging from the lower 70s to mid 80s. The cold front was across west Tennessee and northeast Arkansas at this time. Temperatures will remain above normal tonight with lows Friday morning in the lower 50s to around 60 degrees. On Friday, the front will lift back north as a warm front. This will keep temperatures well above normal with highs in the low to mid 80s. High pressure will be over the southeast U.
349 PM EDT Thu Oct 27 2016 A cold front will continue to move southeast of the area tonight.
611 PM EDT Thu Oct 27 2016 Low pressure over Lake Ontario will move off the east coast tonight. High pressure over the midwest will slide across the Ohio Valley on Friday.
314 PM CDT Thu Oct 27 2016 Large upper ridge over the Rockies will shift east tonight and tomorrow bringing warmer temperatures into the region for the rest of the week.
A very mild October morning across the Tennessee Valley with temperatures already running in the lower to middle 60s in most areas. The latest surface analysis shows the "cold front" situated well to our north positioned from southern IL/IN into the Ozarks. To the south, the low level convergence is very weak and the overall push with the front is rather meager given the relative strength (or lack thereof) of the ridge north of the boundary. Current forecast max temps may be a tad on the cool side as newest ensemble output pushes us into the lower 80s this afternoon. The upper level ridge to our west will quickly build into the region during the overnight hours. The upper ridge will persist through the remainder of the short term period, as we move into the weekend.
305 PM EDT Thu Oct 27 2016 After a few evening showers in the ridges, high pressure will give dry and cool conditions into Friday.
601 PM EDT Thu Oct 27 2016 Building high pressure will ensure dry, but cool weather for Friday.
Temperatures are expected to remain in the low-mid 60s. By evening temperatures will likely be in the mid-upper 50s in the north with upper 50s to the lower 60s in the south. High pressure will then rebuild into the region for Friday resulting in a mostly sunny day. Temperatures look to rebound into the upper 60s to the lower 70s in the north with lower to middle 70s across the south.
321 PM CDT Thu Oct 27 2016 Early-afternoon water vapor imagery revealed a mid-level ridge edging east from the Rockies into adjacent High Plains, downstream from a trough approaching the Pacific Coast. In the low levels, a lee trough was deepening over the High Plains as of 18z with a diffuse warm front that stretched from central South Dakota into eastern parts of Nebraska and Kansas. The warm front will gradually shift east/northeast tonight in concert with a migratory cyclone tracking across North Dakota. Friday, the mid-level ridge over the north-central U. This disturbance will be associated with a surface cold front which will advance southeast into the mid Missouri Valley. Currently, we are forecasting highs in the lower 80s which will be close to the record values of 84, 84, and 85 at Omaha, Lincoln, and Norfolk, respectively.
1251 PM MDT Thu Oct 27 2016 18Z water vapor imagery and RUC analysis indicated large 592 dm H5 ridge in places across southern NM and TX. diffuse trough axis was present across western CWA. H5 ridge over the area will be dominant weather feature through tomorrow leading to dry conditions and passing high clouds through the period. With afternoon mixing would not be shocked to see dewpoints in the west fall into the lower 20s at some point.
Model soundings a bit of saturation in the low levels toward LRD which may allow for FEW-SCT020 to become BKN020 very briefly, but overall should maintain VFR through the night.
A weak inverted trough continues to push closer to the middle Texas coast, however with limited moisture with this system, isolated activity is being confined mainly to the far offshore waters, and even those showers are brief in development.
251 PM EDT Thu Oct 27 2016 Cold front exits to the east this evening/tonight.
123 PM EDT Thu Oct 27 2016 Low pressure over lake Erie will move east dragging a cold front across the area by the afternoon. High Pressure will slide across the Ohio Valley on Friday. Another low pressure system will cross the Great Lakes over the weekend.
244 PM CDT Thu Oct 27 2016 There is a migrating anomalous upper ridge from the desert southwest through the northern plains today. Deepening trough over the eastern Pacific just off the California coast. An abnormally strong ridge of high pressure will build east across the plains overnight and spread h85 temps of 20C or greater across the Sandhills. Increasing subsidence associated with upper ridge of high pressure will provide for dry conditions overnight. Upper ridge will propagate east through the forecast period bringing above normal temperatures to western Nebraska again on Friday.
1135 AM MDT Thu Oct 27 2016 An upper level ridge will be over the state today and will keep the weather dry and warm. High temps today will be well above average, with upper 70s to lower 80s along the I-25 corridor, lower to mid 80s across the southeast plains and upper 60s in the high valleys.
Tonight Through Friday Moist and somewhat unstable southwest flow with two separate low pressure troughs will bring periods of precipitation to the west.
1114 AM MDT Thu Oct 27 2016 Strong upper ridge will remain across the region today as the main axis crosses the CWA. In the low levels. southwest flow will today will bring warmer temps to the area along with dry conditions. Cooler air will gradually filter into the region through the day Friday with highs ranging from the mid 60s across northeast Wyoming to around 80 across south central South Dakota. A stronger cold front will approach from the north while an upper wave crosses Wyoming. The highest elevations of the Black Hills may see it transition to snow late Friday night. mean eastern pac troughing will support active/progressive sw flow over the region through the period, with split flow tendencies.
122 PM EDT Thu Oct 27 2016 High pressure will prevail through the weekend.
Aloft, the upper ridge was building into the region from the west.
300 PM CDT Thu Oct 27 2016 Latest water vapor satellite imagery shows upper level ridge over eastern Rockies and southern Canadian Prairies and upper level trough over the eastern Great Lakes region. Upper level trough is wrapping low stratus deck of clouds and sprinkles/drizzle across much of the forecast area per latest visible satellite imagery and mosaic radar. Upper level ridge will build into the Upper Midwest tonight into Friday.
Surface wise, high pressure is centered over the southeast United States with a lengthy ridge nosing down the Florida peninsula while lower pressure covers most of the northwest Caribbean sea.
341 PM EDT Thu Oct 27 2016 Low pressure over Lake Ontario will move off the east coast tonight. High pressure over the midwest will slide across the Ohio Valley on Friday.
High pressure aloft with increasing amounts of middle to high level clouds. Strengthening lee sfc trof. High pressure sliding over New Mexico will keep temperatures above normal through the weekend. These clouds will make it feel a bit cooler with filtered sunshine.
257 PM MDT Thu Oct 27 2016 The ridge of high pressure that is overhead today will shift to the east tonight. High level moisture moving through the western part of the ridge will keep the high cirrus. Snow level should remain high so only the highest peaks will receive limited snow.
Dry conditions will persist across western Kansas today as short range models indicate broad upper level ridging moving across the Colorado Rockies into the Western High Plains during the period. A fairly dry air mass in the lower/mid levels and a weak flow aloft will hinder any precip chances through Thursday night.
355 PM EDT Thu Oct 27 2016 A weak cold front will approach from the west tonight and cross the area early Friday.
Upper ridge axis over the central CONUS will shift east into the Great Lakes late tonight and Friday. Corresponding area of high pressure at the surface will slide overhead tonight. Low pressure tracking through the Upper Mississippi Valley will then start to send warmer below 850mb into the area late tonight. High pressure will remain the dominant influence on the weather tomorrow even as the center shifts into the Eastern Great Lakes. Strong low-level jet and warm front will keep gusty winds and mild conditions around for Friday night, with temperatures actually rising overnight behind the warm front.
Expect dry weather under high pressure today and maximum temps will be 10 to 15 degrees above normal. Strong high pressure has led to dry conditions with well above normal daytime temperatures again today across the Northland.
WV imagery this afternoon continues to show mid level wave moving out of the forecast area and being replaced by ridging aloft. This ridging will provide warming/drying in the column with the only appreciable moisture left in the boundary layer and best over southern portions.
center of 590 upper high slowly moves east into west Texas during the day remaining nearly stationary tonight as upper trough approaches the west coast. Afternoon temperatures warm into the low to mid 80s per 850mb temperatures. upper high centered over much of Texas and low pressure off the northwest coast keeps the forecast area under southwest flow aloft.
However, the cooler air generally does not arrive until much of the precipitation has moved east. A transitory ridge will pass through the Northern Rockies on Friday night creating a respite from the precipitation.
SHORT TERM (Tonight through Friday Night): 500mb ridge across northwest Texas and a 500mb inverted trough moving across the Yucatan peninsula into the Bay of Campeche tonight will provide northeast winds aloft across the CWA. Low to mid level moisture will be limited across south TX and the northwest Gulf of Mexico but a few showers will develop offshore the lower TX coast tonight and move possibly inland by Friday morning. Moisture will gradually increase across the western Gulf of Mexico Friday into Friday night as the 500mb inverted trough across the Bay of Campeche moves westward.
307 PM MDT Thu Oct 27 2016 Quiet weather prevails this afternoon w/ broad upper-level ridging in place across much of the central CONUS. Lee troughing over the high plains has kept wind speeds considerably lower to the east. More in the way of cloud cover on Friday, so believe temperatures will be some what cooler than today.
340 PM EDT Thu Oct 27 2016 High pressure will prevail through the weekend.
619 PM EDT Thu Oct 27 2016 Low pressure will move east of the area early tonight bringing and end to the rain for most areas shortly after sunset.
159 PM MDT Thu Oct 27 2016 A large upper level ridge of high pressure covers the Rocky Mountain Region. the upper ridge flattens and moves into the Central Plains States. Colorado will be on the back side of the ridge. GFS and ECMWF model guidance do show high temperatures in Denver a couple of degrees warmer than today. The increased southwest flow aloft should result in breezy conditions across the high country. could produce a few light showers across the high country by late afternoon. Southwest flow aloft will prevail as an upper level ridge moves off to the southeast of Colorado.
248 PM CDT Thu Oct 27 2016 The weather remains pretty quiet with an unseasonally warm airmass in place across the Central Plains under the influence of an upper ridge of high pressure. At the surface, a high pressure ridge will exit east of the Missouri River tonight while a low pressure trough deepens along the high plains. Very warm temperatures in the low/mid 80s are forecast for our western zones which are a solid 20 to 25 degrees above normal highs which are around 60 degrees this time of year.
as some partial clearing occurs in wake of a cold front.
355 PM EDT Thu Oct 27 2016 High pressure centered over the Southeastern portion of the country will remain in place through the rest of the week.
1128 AM MDT Thu Oct 27 2016 Warm and dry conditions will be in place today under a building ridge of high pressure. The ridge will be shifting east tonight with increasing southwest flow on Friday. Plenty of high level moisture working through the ridge will send thin blanket of cirrus overhead, helping to knock a degree or two off what otherwise will be record or near record warmth.
A low-level ridge is developing over the Gulf Coast states and Texas with mid-and upper-level ridging taking form over far west Texas into northern Mexico. Records highs are in the low and mid 90s, so it is unlikely that those will be reached.
Some partial clearing is occurring ahead of the true cold front which is still located up in southern Kentucky. a slightly cooler and drier air mass will move into the Tennessee Valley for Friday. A cooler NE flow may keep highs in check by a few degrees.
Expect dry weather under high pressure today and maximum temps will be 10 to 15 degrees above normal. Occasionally dense cirrus cover will persist today, as we remain under strong high pressure. Unseasonable warm and dry weather will peak today across the area as a large scale ridge axis moves over the Four Corners. Expected temperatures to climb well above seasonal averages for this time of year with the highest temperatures likely to occur today across the region. The ridge will slowly move eastward with its axis expected to be over the panhandle of Texas around midday Friday.
Deep upper level trough extending from SE LA into the central Gulf will thicken upper level cirrus over the area through this evening and overnight. Lows will remain mild in the lower to mid 70s near the coast with mid 60s across the interior. High pressure ridge will be reinforced across the Southeast U.
/issued 144 PM CDT Thu Oct 27 2016/ Another day of unseasonably warm temperatures today as we remain under the influence of an upper ridge. A few of the Hi-Res models show a few showers/storms developing across SE Permian Basin later this afternoon but with the upper ridge getting stronger and no mid level support, think chances of this occurring are extremely low. The upper ridge will slowly shift east over the next few days and flatten somewhat to the SE through the weekend.
326 PM CDT Thu Oct 27 2016 An impressive upper level high pressure ridge will continue to expand eastward across the southern plains tonight and Thursday. Tonight expected to be slightly more mild as the upper ridge builds in, but still areas mainly in the western South Plains and southwest Panhandle are likely to dip again below guidance numbers. The very dry airmass and nearly full sunshine on Friday - some high clouds increasing especially late in the day - favor the high side of guidance; on the order of 10 or more degrees above normal. RMcQueen A flatter, but still robust version of the upper ridge will hold sway over northwest Texas through the weekend.
144 PM CDT Thu Oct 27 2016 Another day of unseasonably warm temperatures today as we remain under the influence of an upper ridge. A few of the Hi-Res models show a few showers/storms developing across SE Permian Basin later this afternoon but with the upper ridge getting stronger and no mid level support, think chances of this occurring are extremely low. The upper ridge will slowly shift east over the next few days and flatten somewhat to the SE through the weekend.
350 PM EDT Thu Oct 27 2016 A weak cold front will move through the region this evening.
1240 PM CDT Thu Oct 27 2016 High pressure will bring drier air to the region keeping conditions VFR at all area airports through the TAF period. Temperatures should warm up an additional degree or so from yesterday into the mid to upper 80s given reduced cloudiness, which should also allow low temperatures tomorrow morning to be a few degrees cooler than this morning in the upper 50s and lower 60s. The ridge will become centered over South Central Texas on Friday as it begins to weaken, allowing high temperatures to be similar to where they will be today.
150 PM EDT Thu Oct 27 2016 Cold front crosses Thursday with showers.
326 PM CDT Thu Oct 27 2016 High pressure across the upper midwest continues to shift eastward. A tight pressure gradient will setup up across the area ahead of the next cold front over the weekend.
312 PM EDT Thu Oct 27 2016 Low pressure continues to lift across the eastern Great Lakes and the associated cloud cover will remain in place throughout the remainder of the afternoon into this evening. By Friday morning, cloud cover will slowly decrease and a shift in the winds from the south will allow for warmer temperatures that should reach into the low to mid 60s. The cold front had pushed south to the Ohio River early this afternoon.
Pleasant dry weather will continue across the forecast area tonight and Friday as high pressure remains in control. Temperatures tonight and Friday will run some 5 degrees above normal for this time of the year with lows tonight falling into the lower 60s across the Nature Coast, and mid to upper 60s central and south, with highs on Friday climbing into the lower to mid 80s. Atlantic 500 mb ridge extending into Gulf to be replaced by an even stronger ridge developing across northern Mexico and the far southern U.
227 PM EDT Thu Oct 27 2016 A cold front will cross the area this evening. High pressure will build over the area tonight through Friday night.
230 PM EDT Thu Oct 27 2016 Cold front exits to the east this evening/tonight.
246 PM CDT Thu Oct 27 2016 Late this afternoon a surface warm front, albeit pretty shallow, was located near the Missouri River at 19z. As we move into the evening and overnight hours some of this residual moisture in the low levels could allow for additional patchy fog to develop but not confident enough to include in forecast. Went ahead and increased lows a little with the expected south wind and raised wind speeds around the Buffalo Ridge late tonight into Friday morning and then late morning and afternoon increased winds across northwest Iowa. Upper level ridge flattens out over the weekend as wave moves along the US/Canadian border.
As the high moves to the east, the winds will turn to the south/southwest and increase. fast moving upper level disturbances riding over the ridge of high pressure to our south.
319 PM MDT Thu Oct 27 2016 Quiet weather prevails this afternoon w/ broad upper-level ridging in place across much of the central CONUS. Lee troughing over the high plains has kept wind speeds considerably lower to the east. More in the way of cloud cover on Friday, so believe temperatures will be some what cooler than today.
This did lead to a lot of sun allowing temps to easily rise into the lower to mid 80s this afternoon. The culprit is going to be the strong ridge which currently resides over the Desert Southwest region.
439 PM EDT Thu Oct 27 2016 Low pressure will move out of southern New England toward the Gulf of Maine overnight with precipitation developing from southwest to northeast.
Issued by National Weather Service Binghamton NY 242 PM EDT Thu Oct 27 2016 Low pressure will move east of the area early tonight bringing and end to the rain for most areas shortly after sunset.
As of 7z, low pressure located along the southern Michigan border, and will be exiting the state around 12z, taking most of the measurable precipitation with it. There is actually a good deal of mild air on the backside of the low (around 50 degrees in Chicago), and Detroit area and points south will likely hit 50 degrees or slightly better (almost there already), even with low clouds trapped underneath dry slot. Across the far north, temps probably won't get out of the lower 40s with northerly winds developing. Either way, 850 mb temps then quickly warming overnight as subsidence and pronounced upper level ridging builds into Lower Michigan promoting clearing (outside of warm advection high clouds toward morning).
152 PM EDT Thu Oct 27 2016 High pressure ridging down the coast will gradually retreat northeast today with its influence on the area weakening. A dry cold front will cross the area late tonight and move offshore Friday morning. High pressure will follow for the weekend with above normal temperatures expected.
304 PM MDT Thu Oct 27 2016 Upper ridge covers the western CONUS, with northwest flow over the northern plains and mid/high clouds streaming into the region. At the surface, a trough stretches across the western Dakotas and MT/WY. Cooler air will push into the area from the northwest, with somewhat breezy winds across northwestern SD. Highs will range from the mid 60s across northeastern WY, the Black Hills, and northwestern SD to the lower 80s across south central SD. Would not be surprised if there were a few flakes of snow over the higher elevations, but with no accumulation.
145 PM EDT Thu Oct 27 2016 A cold front will bring showers into the early evening, followed by dry and cool weather into Friday. Warmer but unsettled weather is anticipated for the weekend. Cold front now entering eastern Ohio with pre-frontal band of showers now beginning to cross the ridges. Still expect scattered showers with FROPA, while more significant rainfall will shift east of the ridges. Behind the cold front tonight brisk and colder in northwest flow behind the front. Cold advection behind the departing low pressure will be brief, but shower chances will continue tonight, mainly over the north and east. Some snow may mix in as well, especially north of I-80 and in the high terrain. High pressure will settle over the Ohio Valley Friday, with decreasing cloud cover as warm air advection ensures.
117 PM MDT Thu Oct 27 2016 A large upper level ridge of high pressure covers the Rocky Mountain Region. the upper ridge flattens and moves into the Central Plains States. Colorado will be on the back side of the ridge. GFS and ECMWF model guidance do show high temperatures in Denver a couple of degrees warmer than today. Southwest flow aloft will prevail as an upper level ridge moves off to the southeast of Colorado.
An influx of high level moisture continues from the central Gulf and ahead of a weak mid/upper trough passing by to the north. At the surface, high pressure will remain in control. Some dense fog is possible in more fog prone areas but with the high clouds overhead, widespread dense fog is not anticipated.
The upper level ridge axis will shift eastward across the area by mid week. Expect decreasing clouds for all but MGM/TOI overnight as some models indicate higher RH in the lower levels persisting through 12Z on Friday.
255 PM CDT THU OCT 27 2016 Weak high pressure starts to move into the region this evening. Low level clouds that have persisted through the day have limited diurnal mixing and the dewpoints have remained in the low to mid 40s, with yesterdays rainfall likely enhancing the RH near the surface. into the low 70s. Have trended on the higher side of the guidance wind forecast as a result. The warm southerly winds will keep low temps Friday night much above normal, as temps bottom out in the low 60s west of I-55, with mid to upper 50s east of I-55.
