328 AM MDT Wed Aug 30 2017 Upper ridging continues across the western to central CONUS with northwest flow across the northern Plains into the upper Midwest. Weak waves will continue to ride the top of the ridge today bringing some chances for afternoon and evening showers and storms mainly to the western half of the CWA. Upper ridge axis will cross the area Thursday with a strong wave cross WY toward the CWA. Upper ridging will again set up across the western CONUS through the Labor Day weekend bringing dry weather to the region.
305 AM CDT Wed Aug 30 2017 This morning, with high pressure just off to the east, and light winds some patchy fog is again possible early this morning across the eastern portions of the area. The upper level pattern remains unchanged with a large ridge over the west and a trough over the east. Have already been watching this feature as its energy is strong enough to break down the ridge over the west on its way eastward.
Elsewhere an upper ridge remains centered over the inter mountain west with upper troughs off the British Columbian coast and over Ontario. At the surface, A broad area of high pressure remains over the central U.
Increasing monsoon moisture across the region today in response to an incoming upper level trough and a strengthening southwest flow aloft. Thunderstorm development will spread north and east by this afternoon, with scattered thunderstorm development possible across the higher terrain of southwest Idaho and Malheur County. Dry air filters into the region by Thursday morning with the passage of the upper level trough accompanied by a surface cold front.
Light showers heading northward from a warm front over central AL shifting northward ahead of TS Harvey have already begun to affect Cullman County over the last hours. At the surface, a pseudo-warm front will be lifting northward into the TN valley. A strongly veered wind profile may present itself in the vicinity of the warm front resulting in 1km SRH values increasing into the 150-200 m2/s2 range to start the day, then increase further as a low level jet intensifies as Harvey moves into closer proximity.
Isolated thunderstorms were over the higher terrain moving south in the northerly flow aloft. Storms will primarily be restricted to the higher terrain through the rest of the day and into the evening. The rest of the lower elevations should remain dry. Temps tonight should cool down into the 50s across the Plains and 30s and 40s across the higher elevations. Mid lvl flow will continue to be northerly and nearly all isolated storms will remain over the higher terrain.
155 AM EDT Wed Aug 30 2017 Weak high pressure will build into the area through Wednesday. However, most of the higher res models are keeping our area mainly dry so will just allow for a 20 pop across northeast portions of our area through the afternoon. Lows Wednesday night will mainly be in the lower 60s. Focus shifts to the remnants of Harvey which look to track slowly north from the lower MS VLY into the OH VLY late this week into this weekend.
Activity will move toward the S and SW off the higher terrain.
311 AM CDT Wed Aug 30 2017 Quiet weather will continue across the area as high pressure over the Midwest prevails through the end of the week. Surface analysis shows the center of the high over IA and fog is developing or has developed under the high. The high pressure over IA will move east through the day and into the overnight hours. But it will still greatly influence the nocturnal weather into the lower Missouri valley.
220 AM EDT Wed Aug 30 2017 A ridge of high pressure will remain over the region today while an ocean storm passes well to our south. A cold front will move southeast through the region Thursday, and provide a chance of showers, especially in the mountains.
515 AM EDT Wed Aug 30 2017 Weak high pressure over the region today and tonight will shift off the coast Thursday.
154 AM EDT Wed Aug 30 2017 Weak high pressure today. Cold front Thursday night, as moisture from remains of Harvey move into area through the weekend. Cold front drops south across the upper Ohio Valley as an increasing amount of tropical moisture moves up from the south ahead of Harvey, putting forecast area more or less into a squeeze play.
A broad area of high pressure in the mid/upper levels of the atmosphere will continue to dominate the weather picture over the Rockies and adjacent High Plains through tonight.
High pressure will continue to be in place at 500mb. Temperatures look to be close to normal for this time of year, with perhaps a tendency to be slightly warmer, by a degree or two.
It will arrive near our area with a sharpening gradient toward a Low pressure center somewhere from 998-1000 or 1002 mb, depending upon your model of choice. Word of caution-- the models show some re-deepening of the Low upon its ejection across west Tn.
303 AM EDT Wed Aug 30 2017 Upper troughing over the Midwest these next couple of days will act as a magnet, slowly drawing up the remnants of Tropical Storm Harvey into the Ohio Valley by the end of the work week. Thursday evening, the model consensus places the center of Harvey's low pressure area near the AR/TN/MS border. This band would come as the upper low merges in with the trough over our area. 5-2" range with this band, but will be higher still closer to the low.
300 AM EDT Wed Aug 30 2017 Dense fog gradually dissipating/mixing out during the morning hours, and with enough sunshine anticipated this afternoon, still expecting maxes near 80 degrees ahead of a cold front which will be dropping south through northern Lower Michigan. Seasonably strong high pressure (1026-1028 MB) becoming firmly established over the northern great Lakes Thursday night, and temps should be able to drop into the 40s even with winds failing to fully decouple.
Then we will have partly sunny skies until the arrival of a cold front during the afternoon hours. Warm advection will allow temperatures to rise a couple of degrees above normal, along with dewpoints climbing into the lower 60s before the front arrives. The front will exit the area by late evening, with clearing and cooler air moving in later tonight.
358 AM CDT Wed Aug 30 2017 Upper level trough over Ontario will move east and amplify. Upper level ridge over the northern Rockies will move over the area Thu. Upper level trough over the northeast Pacific will move across MAN/Northern Plains on Fri.
The western edge of the cloud shield from "Harvey" will continue across the eastern counties today which should help keep highs there a little cooler.
The northerly flow aloft between the ejecting Harvey and the western United States ridge will keep us in a pattern with only low precipitation chances and slightly cooler than average temperatures over the next few days.
For tonight, a cold front will push into the far north late. Thursday, the cold front will push through the area. Thursday night behind the cold front dew points will fall, making for a noticeable drop in humidity. Main story over the weekend will be warmer temperatures than we have seen in a while.
420 AM EDT Wed Aug 30 2017 Mid and high level clouds will continue over there area as High pressure ridge continues to keep a low pressure system to the southeast of the forecast area.
much drier conditions will begin to settle over the region as the upper ridge builds in from the west. Daytime high temperatures could be warming into the lower 90s with lows in the lower to mid 70s.
624 AM EDT Wed Aug 30 2017 Weak high pressure today.
Surface wise, a broad region of high pressure is spread across our marine district. A deep tropospheric western Atlantic ridge extending across our entire county warning area will slowly lift northward into the Florida Peninsula over the next couple of days.
Latest WV satellite shows high pressure aloft currently centered near the Arizona/Utah border.
Trough of low pressure will lift from NE FL this morning, into SE GA this afternoon. Thursday: The upper level ridge is forecast to build eastward from the western Atlantic into the central Florida peninsula, with Harvey rounding the northwestern side of the ridge. Any lingering troughing and shear is forecast to push to the north of the region, with drier conditions forecast compared to Wednesday. Highs will be in the low to mid 90s, with lows in the 70s.
Relatively quiet WX pattern as a storm system off the Mid Atlc coast lifts into the Canadian Maritimes, allowing the Bermuda ridge to build north out of south FL. This dry will advect into central FL as the high lifts north, though not in time to completely quash diurnal convection.
An inverted trof (sfc-800mb) remains in place and will be the focus for storm development this afternoon and this evening.
1153 PM MDT Tue Aug 29 2017 Couple disturbances moving across the area into this evening with the most visible one moving towards the park with an apparent weak trailing frontal/trough boundary of isolated convection across ern ID. Could still see some drier lightning in the lower foothills but the majority of the mountains will likely not have 'dry' lightning.
1233 AM CDT Wed Aug 30 2017 A weak cold front was oriented west-east across central North Dakota. A weak southerly low level jet was established over the eastern Dakotas, extending as far north as the surface cold front. Mesoanalysis reveals some CAPE along and south of the cold front.
414 AM MDT Wed Aug 30 2017 Strong high pressure will remain centered over the Great Basin today and continue to be the dominant weather feature over the western U. Small amounts of moisture will rotate around the high and flow over the area from north to south. Tonight and Thursday two weak troughs will travel through the northern Rockies and flatten the ridge. As the two troughs exit the northern rockies mid-range models show them consolidating and initiating frontogenesis which will drop down the front range of the mountains. This will also bring a few to 5 degrees of cooler Thursday. Thursday night the weak front mentioned above will focus showers over the San Juan mountains and the lower elevations of the four corners.
150 AM EDT Wed Aug 30 2017 A weak area of low pressure will continue east across the Ohio Valley tonight into Wednesday. A cold front approaching from the north will cross Lake Erie into the area on Thursday.
The steadiest convection continues to be northwest of the low pressure center along the Texas and Louisiana border. Unfortunately, the latest short term guidance continues to have the highest QPF totals along and east of the Sabine River.
306 AM CDT Wed Aug 30 2017 High pressure across Mid-America in concert with dry northwest flow will support continued mostly quiet weather through the weekend.
652 AM EDT Wed Aug 30 2017 Weak high pressure will extend across the area into tonight. A cold front will drop south across the region on Thursday and then stall just south of the Ohio River.
422 AM EDT Wed Aug 30 2017 Weak high pressure will extend across the area into tonight. A cold front will drop south across the region on Thursday and then stall just south of the Ohio River.
Our stretch of dry weather will come to an end on Thursday as a cold front moves into the region and produces scattered to numerous showers.
232 AM MDT Wed Aug 30 2017 Upper level ridge will be located near the Four Corners region today with northwesterly flow aloft across the CWA.
309 AM CDT Wed Aug 30 2017 As of 7Z, a cold front is located just north of this CWA with dew points remarkably lower over ND. This front should reach our northeast CWA today with dew points dropping into the lower 50s.
Expect clear skies tonight, with light winds and overnight lows mainly in the lower 60s.
Warmer air will push into southern Wisconsin ahead of an approaching cold front, so high temperatures inland will end up near 80. The cold front will drop south across the area this evening and into tonight.
1245 AM CDT Wed Aug 30 2017 Weak low pressure just east of Illinois has kept some spotty clouds still lingering across eastern Illinois. Most areas are clear, with light northerly winds, due to high pressure centered in western Ontario Canada and extending south through Iowa and NW Illinois. Low temps look to settle out in the upper 50s to low 60s, and current dewpoints are in the low to mid 60s, so low level saturation looks likely.
Short range models such as CONSShort and HRRR along with 03z SREF place the highest probabilities of dense fog over northern Iowa with other models indicating widespread dense fog.
214 AM MDT Wed Aug 30 2017 A 594dm high pressure center remains centered over southwest Utah early this afternoon with northerly flow aloft over the area. The upper ridge is forecast to slowly move east tomorrow as an upper level trough and pacific cold front move onto the west coast. A few mid and upper level clouds will spill over the ridge and into the area from the north, especially Wednesday.
Lows in the upper 50s to the lower 60s look good. High pressure will dominate over the area tonight, keeping conditions dry under mostly clear skies. Another area of high pressure will begin to drop out of Canada on Wednesday, with a weak frontal boundary pushing through ahead of it. Thursday: A 120kt jet moving into the Pacific Northwest will cause the upper ridge over the area to buckle, with a weak wave moving into the western Dakotas/eastern Montana late in the day.
Weak Low pressure over Michigan will exit to the east tonight. allowing high pressure over the plains states to build across the Ohio Valley tonight. The high will bring dry weather to Central Indiana through Thursday Night.
Red Flag Warnings will continue Thursday as a dry cold front pushes through the region resulting in sustained west winds of 10-20 mph with gusts up to 30 mph. High pressure will re-establish itself over central Idaho.
A very hot weather pattern is expected across the Mojave Desert Region through the remainder of the week as high pressure parks over southern Nevada and surrounding states. Limited moisture circulating around the area of high pressure will lead to isolated showers or thunderstorms over the mountains each afternoon. Storm chances and afternoon temperatures will trend slightly downward over the weekend as a low pressure system moves through the northwestern states and weakens the high pressure.
General weather pattern is expected to continue over the next several days as strong high pressure wobbles across the region.
The upper air pattern across the CONUS this morning features A potent upper level ridge across the western U. Meanwhile, a broad and disorganized trough extends across the Great Lakes and New England. At the surface, two substantial low pressure systems are apparent in Tropical Storm Harvey and a compact low off the new England Coast, remnants of Potential Tropical Cyclone 10, which never became a Tropical Cyclone. As far as temperatures are concerned, with drier conditions and less cloud cover, we look to rise into the low to mid 90s inland, with upper 80s along the coast. Lows will remain in the low to mid 70s most areas, and near 80 along the coast.
Relief from the heat will continue through Wednesday as an upper level trough pushes inland across the Pacific Northwest. This will bring cooler conditions to coastal and valley locations with overnight/morning low clouds.
Upper level high pressure will be the dominant weather feature for the next 7 days resulting in above normal temperatures for the entire area. This in combination with mid level disturbances moving clockwise around an upper high over the four corners region. Temperatures will be cooler today across the region due to an increase in cloud cover as well as 500 mb heights falling in response to an upper trough moving into northern California. The upper trough over northern California is forecast to shift east. allowing an upper ridge to build from the Eastern Pacific over northern California and the Pacific Northwest.
458 AM EDT Wed Aug 30 2017 A narrow north to south ridge of high pressure will slide east across Pennsylvania today. A strong cold front will likely push through the region on Thursday accompanied by a few afternoon or evening showers and thunderstorms.
330 AM EDT Wed Aug 30 2017 Weak high pressure over the region today and tonight will shift off the coast Thursday.
236 AM EDT Wed Aug 30 2017 Weak high pressure today.
1046 AM EST Fri Feb 16 2018 It will be breezy and warm ahead of an approaching cold front today.
Sfc analysis shows a cold front extends from southeast MO into southeast OK/north TX, while high pres ridges from FL west acrs the Gulf of Mexico. Aloft, a ridge of high pres remains anchored over the Gulf of Mexico, with moisture streaming acrs northwest Mexico into the southern plains on the northwestern periphery of the ridge.
552 AM CST Fri Feb 16 2018 /12Z TAFS/ A cold front has moved through the KABI terminal early this morning and will continue south across the remaining terminals through mid morning. /issued 517 AM CST Fri Feb 16 2018/ (Today and Tonight) Early this morning, a cold front was entering far northern portions of the Big Country. It will be mostly cloudy and considerably cooler today with temperatures falling into the 40s across the Big Country and in the 50s elsewhere by this afternoon. Lows tonight will range from the upper 30s north, to the low to mid 40s south.
Overland, this fog is quickly retreating and dissipating northward as daytime heating mixes out the lower atmosphere.
An approaching cold frontal boundary will move southeast across the region today, resulting in winds veering to the north with sustained speeds of 10-15 kts and higher gusts during the late morning-the afternoon, before relaxing to below 10 kts around sunset. In addition, this cold front will bring about the chance of intermittent -DZ and scattered -RA with perhaps a lull during the evening before returning overnight. Have tried to time the rainfall and cold frontal passage with this TAF forecast. /issued 500 AM CST Fri Feb 16 2018/ The cold front is about to push into the NW corner of our CWA with gusty Northerly winds.
530 AM CST Fri Feb 16 2018 A cold front has moved through the northern terminals turning winds around to the north with an increase in speeds as well. Water vapor imagery reveals the major players quite clearly this morning, namely broad ridging centered over the western Gulf of Mexico and a positively tilted trough over the west.
As cold high pressure drifts south of the area southerly flow will develop and temperatures will try to recover. Parts of northwest IA and southwest MN will only warm into the lower 20s. On Saturday a trough of low pressure will swing through and bring a small chance for a little light snow. As the trough passes a mixy environment will develop and temperatures will climb to around or a little above normal, with highs from 30 to 40.
409 AM CST Fri Feb 16 2018 A cold front has moved through all but the far southeast part of the forecast area early this morning.
A cold front pushes southward into Central AL this afternoon increasing rain chances, especially north of I-20. This could increase chances for rain showers again north of I-20 as this effective warm front gets pushed back into Central AL. I wouldn't be surprised to see a few sites reach the low 80s by this afternoon.
Temps should remain above freezing through the period with snow levels holding over 9000 feet MSL. /issued 409 AM CST Fri Feb 16 2018/ The cold front continues to rapidly push south across the forecast area this morning and will clear our counties within the next hour. Lift associated in this region of the jet combined with the passage of the base of a weak trough will combine to produce the precipitation.
503 AM EST Fri Feb 16 2018 A cold front will continue to work through the region today.
445 AM CST Fri Feb 16 2018 Latest sfc analysis shows the cold front moving thru the South Plains, w/fropa expected at KMAF ~ 11Z. Further out, WV imagery shows the upper trough pushing the cold front extending from the Great Lakes region into the SW CONUS. Accompanying this trough is a strong 180+kt jet maximized around 250mb, which matches up nicely w/GOES HD winds. Meanwhile, an upper trough will dig south out of the PacNW, keeping SW flow aloft over the region and keeping temps up the first part of the week. Unfortunately, a cold front will push into the area Tue, taking temps well-blo normal by Wed afternoon.
/Issued 409 AM CST Fri Feb 16 2018/ A cold front has moved through all but the far southeast part of the forecast area early this morning.
541 AM CST Fri Feb 16 2018 09z/3am surface map shows a cold front along the Ohio River. to the lower 40s south of I-70.
Dry conditions with warmer temperatures will then prevail Saturday.
Meanwhile back to the northwest, a cold front is just entering the northwest corner of AR heading southeast. Despite the cloud cover, another warm day is in store for those spending the majority of the day ahead of the cold front.
A region-wide warming trend is expected today into Saturday as high pressure builds over the eastern Pacific.
Temperatures trend up Saturday with warming aided by a westerly downslope wind component, ahead of a cold front which moves through during the afternoon. Low relative humidity values are forecast to drop to the low 20th percentile across portions of north central Kansas and will continue to mention the potential for near critical fire weather conditions.
High pressure will move from Nebraska to Illinois by this evening. Temperatures will warm a bit on Saturday, reaching the lower 20s in the north and lower 30s in the south/southeast.
304 AM PST Fri Feb 16 2018 Dry and warmer through Saturday with gusty Santa Ana winds near the coastal foothills and below passes and canyons into this morning.
Upper level trough from MAN/Ontario border to northern MN will continue to move east. Upper level trough over the BC coast will move across southern MAN Fri night. Cold front will move in Fri night. With the cold front, will have low pops over parts of the MN side for Fri night. A cold front will be pushing through the area on Saturday. along with an upper trough.
An approaching cold front will slow as it moves across the forecast area today (around noon up north/near sunset around metro). Warm temperatures will continue ahead of a cold front that will enter our north and northwest counties late this morning or early this afternoon and gradually works its way toward the coast late tonight through early tomorrow morning. The front is still expected to linger somewhere between the Highway 59 area and near or just off the coast through Saturday evening. Look for cooler and closer to mid February normal temperatures behind the front along with an increase in rain chances over the weekend (higher chances across our northern counties and lower chances closer to the coast).
The higher elevations of central Idaho will see similar or greater snow amounts, as well. The Highway 2 corridor from West Glacier over Marias Pass will see blizzard conditions for at least a few hours, if not for several hours.
09z/3am surface map shows a cold front along the Ohio River. to the lower 40s south of I-70.
By mid morning and through much of the evening hours, dry high pressure will build into the Upper Great Lakes allowing the lake effect snow potential to end and skies to steadily clear from the west. A cold front will approach the far western U. Some areas near Lake Michigan may see rain and/or freezing rain for much of the event, depending on track and strength. At this time, greatest snowfall looks to be somewhere over the NW half of Upper Michigan, with the least and possibly some freezing rain along Lake Michigan.
These winds will bring warmer temperatures with highs reaching the mid 20s, to the lower 30s. A stronger system, along with a broad upper level trough will cross the region on Saturday.
The front should clear the southern counties just in time before isentropic lift and upstream troughing begin to erode on the front rather quickly this evening. A persistent subtropical trough over the Ern Pacific continues to funnel mid level moisture into TX to keep cloudiness and intermittent light rains in the mix for the remainder of the short term and beyond.
A cold front will move through, along with some showers.
