222 AM EDT Mon Apr 10 2017 High pressure residing along the Southeast coast will bring warm conditions to the Ohio Valley through Monday. A weak cold front will move through the area Tuesday with a chance of thunderstorms.
Satellite shows cold front is moving into western Oregon and Washington early this evening. Weak upper ridge builds in Monday night with clearing skies and cold temperatures. Light rain moving across the area overnight associated with a cold front.
133 AM EDT Mon Apr 10 2017 Mild and windy weather will continue through tomorrow as a low pressure system slowly moves from the upper Midwest into the Great Lakes region. The cold front associated with the low pressure system will begin to move in Monday night. A cold front association with a low pressure system moving from the Great Lakes region into southeastern Canada will swing through the lower Ohio Valley Tuesday into Tuesday evening.
420 AM MDT Mon Apr 10 2017 Corrected typo in short term discussion Valley temperatures have dropped below freezing at several of the lower valleys sites impacted by the freeze warning this morning.
232 AM EDT Mon Apr 10 2017 Bermuda high pressure will extend west into the Carolinas until a cold front settles through the region late Wed and Wed night. Low temps are expected to generally be in the lower to mid 50s, with perhaps a few outlying rural areas dropping into the upper 40s. High pressure will shift slightly eastward and southwesterly flow will be a little stronger on Monday afternoon, particularly in the west where winds will reach 10 kts or so. Monday night moderation in temperatures will continue as lows should only bottom out in the low 50s.
202 AM MST Mon Apr 10 2017 Strengthening high pressure aloft will bring warming temperatures into the middle part of this week as well as very dry conditions. A deep and nearly stationary upper level trough is forecast to sit just off the Pacific Northwest through the foreseeable future. This type of synoptic pattern will result in a series of low pressure systems affecting northern California and the Pacific Northwest, but easily remain well north of our region.
Upper trough the PacNW Oregon will track to the northeast and bring showers across portions of SE Oregon and SW Idaho today, mainly north of a Burns-Boise-Fairfield line. The showers will taper off this evening as the troughs pushes into Montana and an upper ridge builds into the area overnight. The next Pacific system will bring a slight chance of showers to SE Oregon and the higher terrain of SW Idaho Tuesday afternoon. Temperatures will trend warmer each day with highs close to normal on Tuesday.
647 AM EDT Mon Apr 10 2017 Warm and breezy conditions will continue today with high pressure situated east of the region. A weak cold front will approach the area tonight and move through on Tuesday bringing some shower and thunderstorm chances to the area. With warmer air advecting into the area expect temperatures to be slightly warmer than yesterday with high temperatures in the 70s to around 80. Clouds, precipitation, and the cold front will keep temperatures cooler on Tuesday than today with high temperatures in the 60s to low 70s.
443 AM EDT Mon Apr 10 2017 High pressure will linger over the western Atlantic through early this week.
412 AM EDT Mon Apr 10 2017 Under mostly clear skies and east winds of 10 to 20 mph, temperatures are hovering in the lower to mid 70s along the Florida Keys. Surface wise, an expansive western Atlantic ridge is becoming anchored into the southeast United States while low pressure is lingering well east of the Bahamian chain. The combination of a strengthening western Atlantic ridge lying across the extreme southeast United States and low pressure well east of the Bahamas will be the impetus for a strong low level easterly flow. High temperatures will average in the lower to mid 80s and overnight lows in the lower to mid 70s. High temperatures will average in the lower 80s with overnight lows in the lower to mid 70s.
635 AM EDT Mon Apr 10 2017 Warm and breezy conditions will continue today with increasing chances for showers and thunderstorms this afternoon and evening as a cold front approaches.
609 AM EDT Mon Apr 10 2017 High pressure remains centered off the Mid Atlantic coast through mid week.
A pretty weak ridge will develop over the region for much of Tuesday which will translate into a decent spring day with a mix of clouds and sun. Temperatures will continue to be 5 degrees below normal in the lower to mid 50s however sunshine will make it feel warmer.
Dry conditions will continue under clear skies with light easterly winds as our area remains on the southwestern flank of a broad area of high pressure. Deep layer ridging across the region will yield quiet weather through the short term. Mostly clear skies are expected with highs generally in the upper 70s to low 80s, and overnight lows in the low to mid 50s.
The upper level pattern shows Northeast Montana in the middle of a split trough. A weak trough connection between the two will continue low the cooler temperatures, low clouds, and isolated showers today. A larger trough in the West moves across the Divide this afternoon, spinning off a clipper into southern Canada tonight and Tuesday.
234 AM EDT Mon Apr 10 2017 A high pressure system will continue the dry weather through Monday. A weak cold front moves through Tuesday/Tuesday night. High pressure for mid week. Only minor tweaks to temperatures with most sites running a little warmer than forecast. The area will remain in a south to southwest flow of warm, dry air, as high pressure slides off the east coast. The hill and ridgetops will again be warmer than the valleys tonight, and then Monday will feature a warmer afternoon, about 15 degrees above normal. A weak cold front will push through the region Tuesday/Tuesday night, providing some showers and thunderstorms.
/issued 739 PM EDT Sun Apr 9 2017/ NE-E surface winds decreasing overnight to around 8-10 knots, then picking back up to 15-17 knots with gusts 20-25 knots after 14z on Monday as high pressure strengthens over the Atlantic.
425 AM EDT Mon Apr 10 2017 High pressure will remain in place off the East Coast today and Tuesday, resulting in a southwest flow of unseasonably warm air.
Extended Southern Rosebud county through 9 am with an additional couple of inches possible in the higher hills there through sunrise. Troughing over the northern part of Montana overnight shifts eastward on Monday and exits the state Monday night replace by a zonal flow. A big concern this evening will be freezing of roads due to abundant moisture seeing temperatures fall into the 20s.
Might see a period of gusts approaching 40-45 kts Monday morning if surface can tap into the low level jet before it moves away from the area, then gradual diminishing winds during the afternoon. Dry conditions are expected as high temperatures rebound back into the lower 70s across most of the forecast area on Tuesday.
High pressure will remain over the western Atlantic through Tuesday.
1055 PM PDT Sun Apr 9 2017 A cold front will bring a band of rain and snow to the Inland Northwest on Monday morning.
326 AM CDT Mon Apr 10 2017 Currently, an upper level low was centered over the central SD/NE border. At the surface, a low was centered over the border of MN/IA/WI with a cold front extending westward along the SD/NE border and into eastern Wyoming. Today the upper level low over SD/NE is forecast to track east into southern MN/IA. The surface cold front continues moving south as the Canadian high expands southward across the Dakotas.
Over the next few hours expect temperatures to fall into the upper 50s to the lower 60s in most locations. However, the lowest RH values will be down in the Lake Cumberland region where afternoon RH readings could drop into the 20-25 percent range. As we head into tonight and Tuesday, clouds will continue to thicken across the region as a cold front moves in from the west. Highs will range from the upper 60s in the west to the lower 70s in the east. Surface cold front is expected to exit the region Tuesday evening.
Continued thermal ridging aloft and lowering/thickening clouds will keep overnight lows in the mid-upper 50s on ridges with more sheltered valleys in far eastern Kentucky cooling into the mid-upper 40s as a ridge/valley split should materialize ahead of the front. The best chances for precipitation will be in the Bluegrass region nearer the upper forcing and where the front first arrives, but this feature should eventually work through all of eastern Kentucky as the upper trough holds together as it takes on more of a neutral to negative tilt before shearing out across the northern Great Lakes into southern Quebec. Based on the latest model data, the most active part of the extended will likely be Tuesday night, as a cold front pushes across the region.
A tight gradient between high pressure anchored along the East Coast and a frontal boundary over the Plains is creating strong southerly winds across central Illinois this afternoon. with the highest gusts concentrated along/east of I-57.
Main area of convection over northern MO and southern IA associated with a small MCS ahead of a compact short wave trof over SD/NE. Air mass to destabilize ahead of cold front over central IL during this afternoon as MLCapes rise to 1000-1500 J/kg. Another mild day in the 70s ahead of the cold front today with breezy sw winds gusting to 25-35 mph. Good chances of showers and t thunderstorms this evening especially east of the IL river, then diminishing overnight, with just isolated convection southeast of I-70 by late tonight as cold front moves se of IL and approaching the ohio river by dawn Tue. Pacific high pressure over the central and northern Rockies to drift east into the eastern Plains on Tue, across IL Tue night and over lower MI and ohio river valley on Wed.
415 AM EDT Mon Apr 10 2017 Strong high pressure across the region will gradually migrate east and into the western Atlantic through the week while keeping a generally benign weather pattern over South Florida. Meanwhile,models depict a localized trough developing east of the Bahamas during the next couple of days, which gradually moves to the northeast and away form the area. A warming trend continues today with highs climbing into the mid 80s each day this week, and lows hovering the low to mid 60s interior/west coast areas, and around 70 over most locations of the Atlantic coast each night.
This is basically a 24 hour potential watch area for severe development as heating works with approaching cold front, the severe threat will diminish overnight.
432 AM MDT Mon Apr 10 2017 Current KUDX radar loop across east central Wyoming and the far northern NE panhandle shows light to moderate snow from east of Lusk to the Pine Ridge between Alliance and Chadron Nebraska early this morning. Based on webcam images, it looks like 1 to 2 inches of snow is on the ground from Lusk to around Chadron with potentially up to 4 inches along the Pine ridge. Otherwise, winds will continue to decrease today as the low to midlevel pressure gradient decreases across the area. Dry conditions are expected through late Tuesday evening as temperatures increase into the upper 50's (west) to mid 60's (east), warmest across the lower elevations of western Nebraska and far eastern Wyoming.
Max temps in the lower 80s with Min temps moderating into the 60s. The aforementioned mid-Atlantic high pressure reinforces with little adjustment to the synoptic pattern surface or aloft. Strengthening high pressure just offshore the middle Atlantic coast will lead to increasing easterly winds and poor conditions for small craft operators.
127 AM EDT Mon Apr 10 2017 High pressure remains centered off the Mid Atlantic coast through mid week.
508 AM EDT Mon Apr 10 2017 Warm and breezy conditions will continue today with high pressure situated east of the region. A weak cold front will approach the area tonight and move through on Tuesday bringing some shower and thunderstorm chances to the area. With warmer air advecting into the area expect temperatures to be slightly warmer than yesterday with high temperatures in the 70s to around 80. Clouds, precipitation, and the cold front will keep temperatures cooler on Tuesday than today with high temperatures in the 60s to low 70s.
Meanwhile a vigorous low pressure system was centered over southeastern MN and western WI, with a cold front extending westward across northern Iowa, along the SD/NE border. An upper level low along the western SD/NE border is forecast to track east along the surface front. The 12Z GFS/ECMWF/Canadian/SREF are projecting an upper level low moving into southern Canada by Tuesday.
Winds will start to shift to the north later tonight/Monday morning as a cold front moves into the area.
Troughing over the northern part of Montana overnight shifts eastward on Monday and exits the state Monday night replace by a zonal flow. A big concern this evening will be freezing of roads due to abundant moisture seeing temperatures fall into the 20s.
522 AM EDT Mon Apr 10 2017 A sharp ridge aloft and attendant warm air will provided for 2 very warm early April days to start the work week.
137 AM EDT Mon Apr 10 2017 High pressure will keep dry weather and warm weather in the forecast through Monday. Tuesday morning a cold front will approach the area and bring our next chance for rain showers with the chance for an occasional rumble of thunder. Heights will continue to build across the region as ridging aloft builds over the area and deep mid- lvl southwest flow starts to push into the northeast. Tomorrow, the ridging aloft shifts to the east, and this will allow low lvl moisture back into the region, thus expect cloud coverage to increase over the west during the afternoon. Temps Tues morning are expected to remain in the low 50s for much of the area. Next cold front will approach the area from the west on Tuesday.
434 AM CDT Mon Apr 10 2017 A no-frills cold front dividing the CWA from W-E at 3 AM is on pace to exit our southern row of counties by 6 AM, but not before colliding with a dryline poised from Jayton to near Guthrie. As cool surface ridging spills south throughout the day, initially very breezy NNE winds will quell before veering east by midday. Higher dewpoints behind this front and upslope winds should only hinder deep mixing, which is why we're keeping max temps on the cooler side of the MOS spectrum.
135 AM EDT Mon Apr 10 2017 Another dry day is expected on Monday with plenty of sunshine and even warmer temperatures with highs in the mid 60s to lower 70s.
419 AM EDT Mon Apr 10 2017 Southerly flow, under high pressure aloft, will maintain warm and dry weather into Tuesday morning. A weak cold front will bring the risk for showers or a storm Tuesday and Tuesday night.

307 AM EDT Mon Apr 10 2017 High pressure centered off the Carolina coast will circulate unseasonably mild air into the region through Tuesday. A cold front will sink south on Tuesday accompanied by a few showers and thunderstorms.
316 AM CDT Mon Apr 10 2017 All is quiet across the state early this morning, but that is going to change mainly this afternoon and on through tonight and Tuesday as showers and thunderstorms develop along and ahead of a slow moving cold front that will be working its way towards our area. Will continue to carry rain chances on the very low side Tuesday night and beyond as precipitable water values lower and instability decreases with the development of mid/upper level ridging.
329 AM EDT Mon Apr 10 2017 High pressure remains centered off the Mid Atlantic coast through mid week.
Look for a wind shift at SAF during the early to mid morning as a back door cold front pushes in from the ESE.
139 AM EDT Mon Apr 10 2017 A high pressure system will continue the dry weather through Monday.
Winds will become elevated with some gusts possible out of the north to northeast this morning as a cold front moves into the area. /issued 430 AM CDT Mon Apr 10 2017/ Sfc analysis at 08Z shows the cold front about a county north of KLBB, and due into KMAF around 12Z.
/Issued 606 PM CDT Sun Apr 9 2017/ Westerly winds will diminish around sunset and later this evening they will turn around to the north behind a cold front. A cold front will move across the OK and TX Panhandles later this evening and tonight with north winds in its wake. For Monday into most of Tuesday, dry weather will continue as semi-zonal flow to weak upper level ridging prevails.
324 AM EDT Mon Apr 10 2017 High pressure ridging into the forecast area from the Atlantic will dominate through Tuesday.
Coastal areas will be cooler during the afternoon and warmer at night due to the influences of the warmer water.
A cold front is forecast to push across the Hill Country late Monday afternoon into the early evening hours. In addition, a cold front is expected to approach from the north and result in isolated TSRA in the afternoon hours. Upper air analysis this morning showed a ridge from eastern Texas to the Great Lakes and trough over the Rockies. There was a cold front moving through eastern New Mexico. The cold front will move through Central Texas Monday moving to near our northern border where is will stall.
1108 PM MDT Sun Apr 9 2017 Currently Mid level trough axis moving over the state of Colorado at 2 pm. A chilly night is anticipated with lows at or slightly below freezing across most of the plains with 20s in the valley sand tens in the mtns. Flat ridging aloft will move over the region.
Water vapor imagery showing upper trough deepening over central Wyoming while a lead wave helped develop convection over northern Nebraska. Initial cold front making its way south across south central Nebraska with dryline moving east into southern Kansas and western Oklahoma. Better chances for storms look to be this evening into the early morning as cold front swings through eastern Kansas with most guidance leaning this way. Secondary cold front moves through Monday afternoon with a stronger shot of cold air following. Highs will reach the lower to mid 60s.
411 AM MDT Mon Apr 10 2017 Valley temperatures have dropped below freezing at several of the lower valleys sites impacted by the freeze warning this morning.
246 AM CDT Mon Apr 10 2017 Early this morning, a cold front was located across northeast Kansas steadily moving eastward. Temperatures behind the front have quickly fell into the low 50s, while upper 60s can still be noted in east central Kansas where winds are still southerly. Temperatures will be fairly warm ranging from the low 60s in north central Kansas to the low 70s in east central Kansas. A secondary cold front looks to push south across the area this afternoon with more reinforcing cold air behind it. Due to this, low temperatures will be much cooler than average with lows in the 30s, approaching freezing near the Kansas-Nebraska boarder.
This convection will increase on Monday as additional upper level energy moves across AR, as well as a cold front slowly moves through the region. Winds have lowered this evening and will again be elevated on Monday ahead of the cold front. A cold front will slowly approach from the northwest the next couple of days. The front will start exiting to the south as the period ends, with high pressure starting to build into the area from the north.
637 AM EDT Mon Apr 10 2017 Bermuda high pressure will extend west into the Carolinas until a cold front settles through the region late Wed and Wed night. Low temps are expected to generally be in the lower to mid 50s, with perhaps a few outlying rural areas dropping into the upper 40s. High pressure will shift slightly eastward and southwesterly flow will be a little stronger on Monday afternoon, particularly in the west where winds will reach 10 kts or so.

from late morning into the very early afternoon until another vorticity maximum approaches from the sw while the cold front will shift south from central WI. The cold front is expected to accelerate down Lake MI enhancing the convergence for storms but also rapidly cooling the airmass over far ern WI from middle to late afternoon. Medium Much cooler airmass in place with surface/850 lows to our east and low level thermal trough in place. Lingering low level troughing and cool pool should result in a good deal of cloud cover with this regime.
Late this morning and afternoon, showers and storms are expected to fire along a cold front in eastern Iowa, then progress eastward through early evening.
118 AM EDT Mon Apr 10 2017 Southerly flow, under high pressure aloft, will maintain warm and dry weather into Tuesday morning. A weak cold front will bring the risk for showers or a storm Tuesday and Tuesday night.
The clouding up will keep temperatures cooler during the day today and much warmer tonight. The pattern of weak westerlies begins to amplify on Wed as a deeper and stronger storm approaches the west coast, making the flow more southwesterly with an upper level ridge to the east of the forecast area. This southerly flow allows clearer skies and warmer temperatures, especially in southern areas. Besides breezy to windy conditions today with the approaching trough, winds should be light to breezy other times.
617 AM EDT Mon Apr 10 2017 High pressure ridging into the forecast area from the Atlantic will dominate through Tuesday.
