856 PM EDT MON JUN 27 2016 High pressure will build over the mid section of the country as a cold front moves from the Ohio Valley to the east coast. An upper level trough of low pressure will pass east through the Great Lakes region Tuesday and Tuesday night.
Temperatures will be a little warmer today than they were this weekend. The surface flow will become more southerly this afternoon and this will allow for warmer temperatures in the 60s across most of the area. Temperatures overnight will be a little warmer also, with lows in the low/mid 40s. Little will change from tonight into Tuesday with surface ridging continuing to prevail and southwest flow continuing. Temperatures will climb into the low 70s across most of the area under mainly clear skies.
Southwest winds will gradually shift around to more northerly by Tuesday morning as a weak cold front moves through overnight. /Issued 1109 AM CST Mon Jan 30 2017/ Light winds and just some high cirrus today with temperatures expected to reach into the low 70s at many locations. Weak cold front will move through tonight and looks to stall along the I-40 corridor.
A ridge of high pressure will force the storm track well north of the area resulting in a week of mostly clear skies and above normal temperatures.
1025 AM MST Mon Jan 30 2017 Potent clipper impulse now entering ND will commence ridge flattening across the western/central CONUS, cooling temps back to and below seasonal this week. Cold front and associated pressure rise/CAA couplet will enter the fa this morning and support increasing winds, esp on the SD plains.
232 PM MST Mon Jan 30 2017 High pressure continues over the southwestern CONUS through midweek. Forecast challenges in the short term are limited to overnight lows in snow-covered valley locations, where guidance has continued to come in much warmer than reality.
258 PM CST Mon Jan 30 2017 Latest surface map showed low pressure over central Minnesota, with an associated warm front edging into western Illinois. As the low tracks into eastern Wisconsin overnight, skies will be partly cloudy for a time in our area. The mean flow across the eastern 2/3 of the lower 48 states is not as straight west-east zonal for much of the period as suggested yesterday. Now the flow is more northwesterly, which will help keep temperatures at least a little cooler than normal much of the time.
1109 AM CST Mon Jan 30 2017 Light winds and just some high cirrus today with temperatures expected to reach into the low 70s at many locations. Weak cold front will move through tonight and looks to stall along the I-40 corridor.
Skies are mostly sunny this afternoon as upper trough is moving out and weak high pressure builds in tonight and Tuesday. Over the next 24 hours weak ridge will shift east tonight and Tuesday as another weak system moves across the Great Lakes and into the Ohio Valley. Southwest winds ahead of this system will keep temperatures warmer tonight except across valleys of northeast Tennessee.
232 PM EST Mon Jan 30 2017 A low pressure system will provide accumulating snow for much of the region late tonight and Tuesday.
347 PM EST Mon Jan 30 2017 A low pressure system will move southeast across the Great Lakes tonight into Tuesday, bringing snow to the region. The highest accumulations of 3 to 5 inches are expect north of the Toll Road.
A weak cold front at the end of the week will bring cooler temperatures and a chance of precipitation.
Climb winds are still NW/W with lighter speeds under the ridge aloft, ranging from 25-75 kts into flight levels.
High pressure builds across the area today, with lingering stratocumulus ceilings at BNA and CSV giving way to mostly clear skies early today.
A strong mid level ridge will remain in place across the region through midweek. Mid level ridging encompasses much of the Great Basin this morning, maintaining strong valley inversions across northern and central Utah while the higher terrain along with the southern valleys are experiencing mild temperatures.
High pressure will settle over central Florida resulting in very light/calm winds and clear skies. Excellent radiational cooling conditions should produce low temps a couple degrees cooler then model guidance is projecting. While freezing temperatures are not expected, conditions are favorable for patchy/areas of frost to develop late. After a crisp sunrise, full sunshine and a light south to southwest wind will warm temperatures quickly into the 60s by mid day, with max temps reaching the lower 70s in the aftn which is very seasonable for this time of year.
437 PM EST Mon Jan 30 2017 Weak high pressure will build across tonight. Low pressure dropping out of the northern Plains will approach on Tuesday, then weaken and drift to the north as a secondary low develops offshore.
Aloft, a deeper trough is shifting away from the East Coast, while another short wave trough if moving across the Midwest. Temperatures currently range from the lower 30s near the I-64 corridor to around 40 degrees in portions of the Cumberland Valley. An increase in clouds is expected tonight from the northwest, as the short wave trough moves in across the Great Lakes/Ohio Valley regions. Highs will generally range from the low to mid 50s, with some spots in the south possibly reaching into the upper 50s. Winds will diminish into Tuesday night, with lows ranging from the low to mid 30s, with mostly cloudy skies remaining. Eventually, clouds will lower, but remaining VFR, as an area of low pressure passes by to the north.
Winds to the south and west of the low track are expected to reach to near 40mph with gusts to near 50mph across SE ND with wind advisory ongoing for these conditions. Depending on how far west and south pcpn gets during the day could see a -ra/sn mix in the warmer air. The other concern is wind west of the low track.
225 PM MST Mon Jan 30 2017 21z surface analysis had clipper low over central MN with cold front into the southern plains.
North of the low track, narrow but potent mid-level fgen band will produce moderate to heavy snow over central to east-central WI this evening. However, they are picking up on an inverted trough that is expected to develop over northeast WI overnight from the east- central WI lake shore to Iron Mountain which could also enhance snowfall. As low pressure moves southeast and away from the region, the inverted trough (and more focused snowfall) should dissipate over northeast Wisconsin early in the morning. Warmer temps in the mid 20s to lower 30s.
A weak cold front at the end of the week will bring cooler temperatures and a chance of precipitation. Temperatures are the big deal today with more than a few coastal and vly locations slated to reach into the lower 80s. Both the ridge and the offshore flow will weaken on Tuesday. Skies will be mostly sunny and max temps though 2 or 3 degrees cooler than today will still be 4 to 8 degrees above normal.
around the northern periphery of an upper level ridge across the central coast. Temperatures will gradually and consistently cooldown all week as a trough slowly builds in and breaks down the ridge allowing onshore flow to gradually develop. High pressure aloft over California will continue above average high temperatures today.
Meanwhile, an upper level low is cutoff from the main jet near the Baja Peninsula. This morning's mid and upper level RAOB analyses indicate heights are rising from Texas through the Mississippi and Ohio river valleys, mostly as a long wave trough recedes from the northeastern United States. As such, high pressure has expanded east from old Mexico across the Gulf of Mexico. The most recent of several frontal spokes pushed through the Lower Keys and the Dry Tortugas earlier this afternoon, dropping temperatures 5 degrees and increasing wind gusts to 25 mph. Current temperatures range from the mid 60s to the lower 70s, with dewpoints in the mid 50s.
Surface observations show high pressure over Northeast Mexico and Deep South Texas, which will slowly drift eastward across the Northern Gulf this afternoon. /issued 431 AM CST Mon Jan 30 2017/ SHORT TERM (Today through Tuesday): A zonal mid-level flow is expected to persist over Deep South Texas and the Rio Grande Valley in between 500 mb troughiness over the Eastern Seaboard and closed 500 mb low pressure over the Baja Peninsula.
309 PM EST Mon Jan 30 2017 An upper level trough will continue to shift east of the area through the rest of the afternoon. Low pressure will move east across the Great Lakes Tuesday with a warm front crossing the area late tonight into Tuesday morning and a cold front crossing Tuesday night.
The moist air mass over Western Washington, leftover from Sundays weak cold front, will keep skies mostly cloudy through Tuesday morning with spotty light rain or drizzle possible tonight.
Inversion conditions continue today with mostly cloudy skies, continued cool and haze in the lower valleys. Westerly flow aloft has set in over the Pacific Northwest as a weak arctic cold front is moving south into Washington and northern Idaho. Increasing moisture under the westerly flow will interact with this cold front. The upper ridge anchored over the interior NW will gradually flatten as a low approaches from the Gulf of Alaska. This systems southern reach is still uncertain as it will be moving into a strong ridge being supported by a deep low off the CA coast.
115 PM MST Mon Jan 30 2017 A nearly zonal pattern remains in place with very weak ridging in the southwest and a seasonal Hudson Bay low providing a very large and broad troughing pattern from the northern Plains to New England. Tuesday: A cold front will push across the region Tuesday night. Highs are still expected to reach the lower 50s to lower 60s with temperatures falling through the afternoon and falling sharply through the evening.
1041 AM MST Mon Jan 30 2017 18Z TAF CYCLE A strong ridge of high pressure centered over the California coast will result in dry and stable weather over New Mexico with VFR conditions expected the next 24 hours. Northerly flow on the back side of the ridge will allow thin patches of cirrus to cross mainly over the NW half of NM. High pressure over California will drift southeast through this week and bring very dry and mild weather to New Mexico. Winds will be a bit breezy along the east slopes of the central mountain chain and portions of the high plains through this week.
1252 PM EST Mon Jan 30 2017 A low pressure system will move southeast across the Great Lakes tonight into Tuesday, bringing snow to the region. The highest accumulations, generally between 2 to 4 inches, will be north of US 30.
347 PM EST Mon Jan 30 2017 Snow showers will slowly diminish this afternoon across central New York as high pressure briefly builds over the region.
210 PM EST Mon Jan 30 2017 Weak high pressure will build in from the west tonight then crest over the region on Tuesday.
330 PM CST Mon Jan 30 2017 A weak cold front is slowly making its way south across the local area this afternoon. with many afternoon readings already in the lower to mid 60s across the region. As the aforementioned cold front then continues to make its way south of the local area through the overnight hours. winds will finally subside across the local area and despite the cooler forecast temperatures, Tuesday should end up being a fairly nice afternoon with temperatures in the 40s and winds less than 15 mph. Northwesterly flow will be in place to start the extended periods with an upper level trough across the eastern Pacific expected to eventually move on-shore across the Pacific Northwest towards the end of the work week and track across the intermountain west over the upcoming weekend.
Mesomodels are picking up on lake enhancement across the Door Peninsula along with an inverted trough over northeast WI tonight. WV imagery showed a potent vort movg through southern Alberta, with a developing low pressure system in southeast Alberta, where a 3-hour pressure fall max of nearly 5 mb was located.
1008 AM CST Mon Jan 30 2017 Winds are light across the Mid-South as of 10 AM but are forecast to increase to 6-12 mph this afternoon in response to the surface cyclone moving across the upper Midwest. The upper trough is shifting east this morning with mostly clear skies prevailing across the region with just a few patches of mid cloud.
326 PM CST Mon Jan 30 2017 A weak cold front will move across the area tonight, but no precipitation is expected due to lack of moisture through the column and unfavorable upper dynamics across the CWA.
134 PM MST Mon Jan 30 2017 A nearly zonal pattern remains in place with very weak ridging in the southwest and a seasonal Hudson Bay low providing a very large and broad troughing pattern from the northern Plains to New England. Tuesday: A cold front will push across the region Tuesday night. Highs are still expected to reach the lower 50s to lower 60s with temperatures falling through the afternoon and falling sharply through the evening.
SHORT TERM:(Tonight through Tuesday Night): Zonal 500mb flow will continue across Deep South Texas ahead of a weakening closed low pressure system over the Baja Peninsula. At the surface, high pressure is directly overhead the southern tip of Texas and Northeast Mexico.
313 PM CST Mon Jan 30 2017 Models in good agreement amplified ridge currently over the west coast will break down with large scale flow transitioning to near- zonal over the conus heading into this weekend.
These winds will abruptly shift to the west later this afternoon as the surface warm front moves into the forecast area. While temperatures will temporarily rise above freezing behind the warm front, a cold front will then drop south later this evening and overnight, re- freezing any melted snow on untreated roads.
/issued 1008 AM CST Mon Jan 30 2017/ Winds are light across the Mid-South as of 10 AM but are forecast to increase to 6-12 mph this afternoon in response to the surface cyclone moving across the upper Midwest. The upper trough is shifting east this morning with mostly clear skies prevailing across the region with just a few patches of mid cloud.
A ridge of high pressure will force the storm track well north of the area resulting in a week of mostly clear skies and warmer than normal temperatures. Could be a little warmer in spots than currently forecast. Thus will run out an mid-morning update for slightly warmer highs this afternoon. Dry conditions with warmer temperatures this week. The warmup is the due to an upper level ridge over the SW corner of the country that has shunted the storm track to the north. This ridge will be the main player influencing our weather through the coming week although it will fluctuate in strength and form through the period. Toward the end of the week and into the weekend the ridge will break down somewhat allowing weakening systems to move across the region.
The biggest difference this will have on the area will be in the form of warmer morning lows with mid 40s to near 50 tomorrow morning and then lower to mid 50s Wed morning. The biggest issue the medium range models are trying to solve for our area is the current low over the Baja and then the cold front Fri and Sun. As prev forecaster mentioned a cold front does try to push in Fri but stalls and that is another question, how far south does it make it.
/Tonight through Tuesday/ Area of low pressure centered across central MN to slide east/eastsoutheastward into eastern WI overnight. For Tuesday temps to remain above average but still be several degrees cooler than temps today with strong caa expected through the day. Expect more steady or slightly falling temps across the north, with mainly cloudy conditions with low stratus in place behind the cold front pushing south late tonight.
324 PM EST Mon Jan 30 2017 A low pressure system will move southeast across the Great Lakes tonight into Tuesday, bringing snow to the region. The highest accumulations, generally between 2 to 4 inches, will be north of US 30.
1259 PM EST Mon Jan 30 2017 A trough will shift east of the area this morning allowing a ridge of high pressure to build east across the area this afternoon. High pressure will return to the region for the middle portion of the week. High pressure pushing up the oh valley later today is bringing drier air in from the west while temps aloft are starting to warm. This will bring another round of snow to the area overnight, starting in northwest Ohio towards late evening as lift ramps up along the warm front. Airmass is too warm by that time for pure lake effect but some lingering lake enhanced snowfall as another low level trough swings east across Lake Erie.
340 PM CST Mon Jan 30 2017 At H5 closed low over the Northeast CONUS with trough extending into the Carolinas. Cutoff low over Baja with ridge into the Pacific northwest. A cold front is slated to push in from the north Tuesday morning across northern Nebraska, then move across southwest Nebraska during the afternoon hours.
1029 AM MST Mon Jan 30 2017 A broad ridge of high pressure over the western US will continue to dominate the short term forecast. Dry conditions will persist with high clouds wrapping around the ridge through Tuesday.
139 PM EST Mon Jan 30 2017 A low pressure system will provide accumulating snow for much of the region late tonight and Tuesday.
While not red flag warning criteria, conditions are supportive of fire growth especially grass fires given the low RH. Upper level pattern is beginning to flatten but still a trough over the eastern U. and a ridge over the western U.
1242 PM EST Mon Jan 30 2017 A trough will shift east of the area this morning allowing a ridge of high pressure to build east across the area this afternoon. High pressure will return to the region for the middle portion of the week. The trough that produced the enhanced snowfall over the western snowbelt counties this morning is moving off to the se. High pressure pushing up the oh valley later today will bring drier air in from the west. This will bring another round of snow to the area overnight, starting in northwest Ohio towards late evening as lift ramps up along the warm front. Airmass is too warm by that time for pure lake effect but some lingering lake enhanced snowfall as another low level trough swings east across Lake Erie.
255 PM EST Mon Jan 30 2017 High pressure builds across the region tonight with mostly clear, cold, and calm conditions.
145 PM PST Mon Jan 30 2017 High pressure aloft over California will continue above normal high temperatures through Tuesday.
A weak cold front will bring a wind shift (from mainly SW to mainly NE) to much of Oklahoma tonight into Tuesday morning.
Now that the pressure gradient as eased somewhat and the observed winds speeds have gradually diminished and that the warning was originally set to expire at 11 AM, felt it was best to go ahead and cancel the High Wind Warning there now with the forecast morning update.
As the 500mb weak trough continues to swing to the south out of Canada it will interact with favorable exit region of 300mb jet allowing for episodes of light snow to traverse the northern plains tonight into Tuesday. Slightly cooler for max temps with upper 20s to near 30 expected as the blyr temperatures cool only slightly.
231 PM EST Mon Jan 30 2017 Latest regional surface analysis shows high pressure has built into the Tennessee Valley allowing for a drier and continued cool flow regime over the local area. After a morning of widespread temps at or just below freezing. Some embedded energy in main mid level trough will remain largely north of the area on Tuesday maintaining the benign pattern.
318 PM CST Mon Jan 30 2017 A weak cold front will move south across most of Oklahoma by noon on Tuesday, bringing only slightly cooler air into the region.
Temperatures central and east will be several degrees cooler today as cooler air funnels in from the northeast.
A very weak ridge of high pressure aloft will remain over our area through the next 24 hours. It will be strong enough to deflect precipitation north of us, but clouds will continue to stream through the ridge.
The upper level trough will continue swinging past the region today as a deep low lifts into the northeast CONUS. The tail end of the associated cold front and dryline across central Texas will push into South Texas through the mid to late morning, reaching the coast by the early to mid afternoon. Temperatures will be comparatively cooler today, though still have sufficient time to warm into the low to mid 80s.
1059 AM EST Wed Mar 1 2017 The advance of a strong cold front has brought showers and thunderstorms to the Upper Ohio Region for today. Much cooler temperatures will then last through much of the weekend. Moderate rain will continue for the next hour or two before a break occurs with subsidence ahead of the cold front currently lagging in Indiana. The strength of the line of progged convection is uncertain at this time and will depend on how unstable the lower atmosphere can get before the front arrives. Late day cold frontal passage will end the severe weather threat and return cold and snow showers chances to the region. After the FROPA, upper troughing, cold advection, and limited lake and terrain enhancement should result in scattered snow showers through Thursday as temperatures return to sub average.
Squall line associated with the actual cold front extends from near Fort Wayne to Terre Haute to St Louis, and will continue to push south and east through the morning. Dry high pressure will settle over the Southern Plains tonight and Thursday, with tranquil weather and seasonal temps across the Ohio Valley.
1000 AM EST Wed Mar 1 2017 Deep lyr ridge over central FL generating a deep S/SE flow acrs FL this mrng, as well as a sharp subsidence inversion in the H85-H70 lyr. Sfc/low lvl ridge axis over central FL will maintain a gentle to moderate srly breeze over the lcl Atlc thru sunset.
649 AM EST Wed Mar 1 2017 Thunderstorms will continue through the first part of the day as a cold front pushes southeast across the area. Behind the front, a cooler airmass will settle into the region through the end of the work week. Meanwhile, the convective line associated with the cold front is pushing east across central Indiana and into northwest Ohio.
Clear skies across interior NorCal early this morning as ridging from the eastern Pacific builds into the region. Precipitation chances return over the weekend as the ridge shifts east as a trough approaches from the Gulf of Alaska.
/Issued 322 AM CST Wed Mar 1 2017/ Thunderstorms have largely moved east of the forecast area early this morning, in advance of the cold front progressing southeastward through eastern Oklahoma and western Arkansas.
628 AM EST Wed Mar 1 2017 It will be warm and windy ahead of a cold front today. Cooler conditions will follow the front for the end of the week. The main issues are windy conditions ahead of a cold front this afternoon and possible severe thunderstorms tonight. VAD wind profile trends support the model guidance of a strong low-level jet ahead of the approaching cold front. The high-resolution models have a timing of mainly 900 pm to 200 am. Leaned toward the higher temperature guidance ahead of the front today. Also followed the higher guidance tonight because of mixing associated with the front. Drying will occur behind the cold front Thursday.
/issued 309 AM CST Wed Mar 1 2017/ An upper trough is centered over the Northern Plains and a cold front is moving southward across West Texas currently north of the CWA. The upper trough will become centered over the Great Lakes on Thursday.
Northwesterly flow expected to continue today under the influence of an off-coast ridge. Moisture embedded in the flow will keep the ridge dirty, with a few showers possible through Thursday morning, mainly across the west-central mountains of Idaho, the Boise mountains, and perhaps into Baker county of Oregon. Drier and warmer conditions then expected across the area Thursday afternoon.
518 AM CST Wed Mar 1 2017 The cold front hat pushed through the area last night and brought severe weather has shifted well to the east this morning. The upper level trough associated with this system will move through the area today.
