1122 PM MDT Wed Apr 5 2017 The quiet weather will continue through the short term period as an transitory amplified ridge works of the Rockies into the High Plains. Warm advection is beginning overhead attm as this ridge builds into the region but will really kick into gear tomorrow. Some high cloudiness is topping the ridge and will be moving through the CWA overnight with clearing toward morning. Guidance trends indicate the threat of widespread freezing temperatures becoming less probable in the critical growing areas. Would not be surprised a few low lying areas drop to just below freezing for a few hours such as around Fruita and in the UnCo River Valley.
427 AM MDT Thu Apr 6 2017 A quiet period of weather over the next several days with upper-lvl ridging expected to be the dominant feature influencing the central Rockies through Fri afternoon.
341 AM EDT Thu Apr 6 2017 Today and Friday: Mid/Upper level trough and associated low pressure which are responsible for severe weather in the panhandle/Central Fl overnight will continue to lift northeast today. The trailing cold front will push through South FL with most of the best dynamics remaining to the north, but a few storms could strengthen and move near the Lake region early in the morning.
142 AM MDT Thu Apr 6 2017 Large upper ridge is building over the western CONUS. A low-level jet will develop tonight ahead of a trough. Upper ridge axis will cross the northern plains Friday, and southwesterly flow will increase as low-level trough moves through the region. An upper trough will approach the region this weekend.
A cold front is pregressing into the eastern Gulf of Mexico, preceded by a broken line of showers and thunderstorms through north Florida, extending to a point just west of Buoy 42003.
422 AM EDT Thu Apr 6 2017 The last line of thunderstorms had exited the forecast area this morning as a strong trough deepened into the southeast. As the closed upper low pushes into the Great Lakes today. Cooler air should gradually push into north and central GA today as winds gradually become more northwest. A cold night is in store for tonight with the possibility of freezing temperatures for the northeast.
Main front has now exited the area and the main upper low is now beginning to swing through. Winds will remain very strong until the low finally lifts away from the area.
Southerly flow will be slightly higher tomorrow afternoon for KDRT farthest away from the center of the high. Upper level ridging and surface light northerly winds will translate to a cool period tonight with lows in the lower 40s over most areas.
Broad southwesterly flow aloft to remain in place through Friday night across the region ahead of an approaching trough. A fairly strong cold front will slide eastward across SE Idaho Friday afternoon and evening.
An upper ridge over Utah early this morning will shift east of the state later today. A mild and increasingly strong southwest will develop ahead of a cold upper level trough which will settle across Utah this weekend.
Strong low pressure through the mid/upper levels will be moving off to the northeast today. Winds will be strong and gusty today on the back side of the strong low pressure system that is moving northeast over northwest Ohio. High pressure will be centered over the lower Mississippi Valley on Friday with light northwest winds resulting in temperatures in the upper 40s northeast to mid 50s southwest. This high pressure will again keep skies clear Friday night to a point where scattered frost will be possible throughout central Indiana.
532 AM EDT Thu Apr 6 2017 It will be windy and dry behind a strong cold front today through Friday. The cold pressure ridge behind the front will be near the forecast area Friday night and patchy frost is forecast. Showers and thunderstorms along the strong cold front will exit the forecast area early this morning. Today will be windy behind the strong cold front. The pressure gradient is forecast to remain tight tonight with strong low pressure north of the area, but there should be somewhat diminished wind because of nocturnal cooling and less mixing. The pressure gradient between low pressure in the Northeast States and ridging in the Lower Mississippi Valley will bring breezy conditions Friday. Diminished wind will occur Friday night as the ridge gets closer to the forecast area.
Light and variable surface winds can be expected through daybreak as weak high pressure ridge lingers over the forecast area. Surface winds expected to increase only into the 8 to 13 kt range during the day as ridge is displaced farther to the east, with all terminals returning to southeasterly by Thursday evening. We have already seen the beginning of the upper ridge building over the area which will keep our weather pleasant. This building ridge will result in gradually warming temperatures into the weekend.
313 AM CDT Thu Apr 6 2017 Latest water vapor imagery shows a highly amplified ridge axis extending from the desert southwest north through Saskatchewan. At the surface, high pressure was located between Rolla and Devils Lake early this morning. Aforementioned high pressure across north central ND will slide into southeast ND this afternoon. Highs today will range from the lower 50s Turtle Mountains and James River Valley, to the lower 60s west.
304 AM CDT Thu Apr 6 2017 Not many changes to the latest forecast as we will remain in a tranquil period through the weekend thanks to upper level ridging.
The mid eve update featured some adjustments to wind and gusts, mainly for areas adjacent to the ridges where wind gusts of 30 to 35 mph have been observed due to downslope enhancement. Otherwise, approaching low pressure is increasing rain chances for the Upper Ohio Region via moisture and ascent increases. Strong upslope/lake trajectory flow of this cold air on Thursday night/early Friday is expected to support accumulating snow, an advisory for which may be needed over the higher elevations. This reflects the highly elevation based nature of this early spring snow.
The upper level low responsible for the unsettled and breezy conditions of late is clearly visible on moisture channel imagery this morning and rapidly moving off into the lower lakes. The high will dominate through the remainder of the period with temperatures running a little bit below normal before a warming trend commences after the conclusion of the short term.
337 AM EDT Thu Apr 6 2017 A large area of low pressure from the midwest will approach from the southwest today then track up to our west tonight through Friday.
Weather will be quiet and warmer the next two days, with highs to around 70F today and in the 70s/around 80F Friday. This will set the stage for a cooler weekend. Surface pressure falls ahead of the trough to the west will create increasing winds Friday, mainly over the western zones. Pressure rises behind the cold front Friday evening bear watching as current progs have shifted the main rises (8-9 mb/6 hrs) further south than last nights progs.
230 AM CDT Thu Apr 6 2017 Upper low was centered over northwest Indiana early this morning, and will continue to strengthen as it moves into western Pennsylvania by early afternoon. Showers/drizzle rotating around the low have become more sparse over the forecast area, with the western fringes near the Illinois River at 2 am. The strong pressure gradient will result in wind gusts of 35-40 mph, especially across the eastern CWA closer to the low. The gradient will start to ease up this evening, as a ridge of high pressure builds east toward the Mississippi Valley. Temperatures over a large part of the forecast area are expected to drop to close to freezing as skies clear.
325 AM CDT Thu Apr 6 2017 An upper trough is just to the east of the region with upper ridging beginning to develop over West Texas and southeast New Mexico with westerly flow aloft. Upper ridging continues over the region on Friday and temperatures are projected to warm up from today, especially across the western CWA.
Lighter winds today as high pressure settles back in. High pressure aloft will continue to bring clear skies.
639 AM EDT Thu Apr 6 2017 Cold front exits bringing falling temps, wind, and showers today. High pressure for the weekend. Convective threat is largely gone at this point as a strong cold front drives showers eastward through the mountains. Strong upper low is still deepening over the southern Great Lakes, with descending air aided by convective showers with the momentum transport. Models have the broad and cold low pressure system, with wraparound moisture and wintry precip, lifting out of the area faster on Friday as compared to previous model runs. In the low lands, morning light snow will end as light rain from west to east during the day Friday. However, the higher elevations of the northern and central mountains will continue to receive accumulating snow, especially Friday morning, before diminishing during the afternoon.
401 AM CDT Thu Apr 6 2017 Early Thursday morning, the forecast area was still under a modest pressure gradient between the strong low pressure departing well east and incoming high pressure over central Nebraska. with the highest temps in north central KS where southerly return flow may start back up and some high cloud cover could build in after midnight.
Early morning IR imagery together with surface obs showed the developing cyclone across the Great Lakes region with some high clouds reaching as far west as I-35.
327 AM CDT Thu Apr 6 2017 A long-awaited warmer and drier spell is upon us. Subjective 00Z upper-air analysis indicates broad upper-level troughing from the western Great Lakes/upper MS River valley toward the lower MS River valley, with ridging across the Great Basin and rising 500mb heights across the Rockies to the High Plains. An 850mb low was centered over IN/IL, with sub-0C temperatures dipping south through IA/MO behind the low.
201 AM EDT Thu Apr 6 2017 A cold front will cross the area during the early morning hours. Showers and thunderstorms will continue into the early morning hours, until the main cold front moves east of the area. The cold front moves east of the forecast area Thursday morning, with drier air moving in behind the front. The main weather issue on both Thursday and Friday will be associated with the strong winds due to the tight pressure gradient between deep low pressure moving from the Lower Great Lakes to New England and ridging moving into the Lower Mississippi River Valley. Temperatures quite a bit cooler on both days, with highs in the 60s.
1101 PM MDT Wed Apr 5 2017 A high pressure ridge aloft extending north from the Desert Southwest, across the Great Basin into the Northern Rockies will bring dry conditions to the western mountains and valleys tonight and Thursday, with decreasing clouds east of the Continental Divide. The ridge is fairly dirty with mid and upper level moisture producing broken cloud cover over Idaho and the Pacific Northwest that will spread over western Wyoming tonight and Thursday.
A second and stronger system, along with a cold front, will bring another round of showers after a brief lull in the activity this evening. However, the same winds will enhance the precip in the higher elevations where total amounts of a half to one inch are possible. Temperatures will be several degrees cooler (slightly above normal) today, and a few degrees cooler (near normal) on Friday.
651 AM EDT Thu Apr 6 2017 It will be windy and dry behind a strong cold front today through Friday. The cold pressure ridge behind the front will be near the forecast area Friday night and patchy frost is forecast. Today will be windy behind the strong cold front. The pressure gradient is forecast to remain tight tonight with strong low pressure north of the area, but there should be somewhat diminished wind because of nocturnal cooling and less mixing. The pressure gradient between low pressure in the Northeast States and ridging in the Lower Mississippi Valley will bring breezy conditions Friday. Diminished wind will occur Friday night as the ridge gets closer to the forecast area.
328 AM EDT Thu Apr 6 2017 A large area of low pressure from the midwest will approach from the southwest today then track up to our west tonight through Friday.
With a cool dry airmass filtering in areawide, temperatures this afternoon to only climb into the lower 70s. Upper-ridge aloft to strengthen through the early part of the weekend allowing for mostly clear skies areawide.
In the higher elevations temperatures will be cold enough to where rain showers will likely switch over to snow showers. The higher elevations will likely get the strongest winds so a wind advisory is in effect for the mountains as well.
137 AM EDT Thu Apr 6 2017 A cold front will cross the area late tonight then move off the coast around daybreak. Another round of showers and storms will move into the area from the west after midnight ahead of an approaching cold front. Showers and thunderstorms will continue into the early morning hours, until the main cold front moves east of the area. The cold front moves east of the forecast area Thursday morning, with drier air moving in behind the front. The main weather issue on both Thursday and Friday will be associated with the strong winds due to the tight pressure gradient between deep low pressure moving from the Lower Great Lakes to New England and ridging moving into the Lower Mississippi River Valley. Temperatures quite a bit cooler on both days, with highs in the 60s.
Stratus gradually burning off this afternoon, with a much cooler airmass across SW KS. Cooler air will filter into SW KS just in time for the beginning of November.
Various CAMS keep the low ceilings pretty much intact until Monday night when westerly flow behind a cold front scours things out. The high over us will depart to the east tonight as low pressure moves into the western high plains. The low remains on track to moves across the Dakotas and into northwest Minnesota on Monday. First, a warm front will lift northeast across the FA during the day. The second item of interest on Monday remains the increasing southerly winds ahead of the low in the Dakotas.
TAFs for northeast Oklahoma and northwest Arkansas are a bit tricky as low clouds at 1000 to 1500 feet have moved into northeast Oklahoma behind a cold front and could possible move into northwest Arkansas as the front moves through. Will hang on to the low clouds across northeast Oklahoma well into the evening hours and will introduce a short period of low clouds at the northwest Arkansas TAF sites. /Issued 1039 AM CDT Sun Oct 30 2016/ A cold front currently stretches from south-central Oklahoma into the southern portions of the Tulsa metro to near the far northwest corner of Arkansas. Low clouds are infiltrating behind the cold front this morning. Temperatures across southeast Oklahoma and west-central Arkansas will once again soar into the 80s as the cold front loses steam as it move south.
There are certainly no signs of anything much different happening tomorrow, although lows tonight should trend slightly warmer in a majority of locales in comparison to last night.
1256 PM CDT SUN OCT 30 2016 A dry cold front is making its way across Central Illinois this morning, with some low level clouds accompanying it. Cooler temperatures filtering in to the northern two thirds of the state, while areas along and south of I-70 still in sunshine and a warmer airmass. a degree or two warmer in the south. 07z/2am surface map shows cold front sinking into north-central Illinois. Meanwhile further north behind the front, temps have dropped into the lower to middle 50s across northern Illinois. High pressure will shift across the region on Monday, allowing winds to veer from northeasterly to southeasterly.
300 PM MDT Sun Oct 30 2016 A Pacific system will move on shore and push the upper level ridge over the Central Rockies east of the region. Winds above ridge line will be strong late tonight and early Monday. Winds turn westerly Monday and will be breezy with gusts to 30 mph across the lower elevations. As far as temperatures go, it will be another mild day with readings in the lower to mid 70s across northeast Colorado.
Current forecast is on track for clouds to gradually increase this aftn from southwest to northeast in conjunction with the approaching low pressure system currently heading into Utah. An approaching Pacific low pressure system will allow CIGS to develop and lower through the rest of today. Conditions should then improve gradually from southwest to northeast later Monday morning, as the low pressure system exits the area generally to the northeast.
Likely a warm day on Monday ahead of a cold front.
High pressure will build into the CWA Monday switching our winds to a more easterly flow which should eventually bring in slightly cooler air.
207 PM CDT Sun Oct 30 2016 Cold front continues to move south through the CWA although it has slowed quite a bit. However with the upper trof moving off,the upper ridge building back in, the north wind will decrease and become light se overnight. JPK Unseaonably warm weather can be expected on Monday as a weak warm front lifts north-northeastward through our area with southerly/southwesterly surface/low level winds and upper level ridging over our region. The only limiting factor for near record highs on Monday will be low level cloudiness expected during the morning, but this should clear out in the afternoon as the warm front lifts north-northeast of our forecast area.
The forecast area is under the influence of high pressure on the surface and aloft. The upper high is centered over Texas and ridges over Florida while the surface location is over Georgia that is producing a moderate easterly wind flow over the southern end of the peninsula and weaker flow to the north. To the south of Florida is a band of deep layer moisture that is held in check by the high presssure. Tonight a cold front will pass through the state and behind it a reinforcing high pressure.
1222 PM CDT Sun Oct 30 2016 Cool high pressure will prevail across the region today with northerly winds becoming southeast through time. Southerly flow tonight allows the low level moisture to move right back into the area, so any clearing we might see earlier in the evening should fill back in with low clouds again Monday morning, which will again erode with time during the day Monday. While it will be warmer back into the 70s mostly for Monday, have cut back highs a couple of degrees from previous forecast due to the expected morning cloud cover.
254 PM CDT SUN OCT 30 2016 High pressure will build back into the region to start the work week. Model depiction of the low level moisture profiles is problematic. HRRR has been introducing some drying from the NE, and although there has been some erosion of the lowest ceiling over the southern half of the state. The struggle will be between general subsidence with high pressure building.
547 PM EDT Sun Oct 30 2016 A cold front is pushing through central Maryland and northern Virginia.
1149 AM MDT Sun Oct 30 2016 Plenty of mid and hi cloud streaming into the area from the west as as the southern streams waves north ahead of the strong trough along the CA coast. It will carry with it a weak cold front that will drag over the northern half of the area Monday afternoon.
The fog and stratus should dissipate fairly quickly late in the morning as wind speeds increase and the highest moisture content shifts northward. Although think much of the low clouds will dissipate, could see some linger across north/northwest Oklahoma.
Strong winds will continue this evening as a low pressure system moves across Nevada.
315 PM EDT Sun Oct 30 2016 A cold front with a weak area of low pressure that travels along it moves south of our area by this evening with some showers over southern areas of New Hampshire and southwest Maine. High pressure will build in from the west later tonight and Monday. Low pressure will pass by well to our north midweek bringing warmer weather and scattered showers.
259 PM CDT Sun Oct 30 2016 Upper level ridge axis has just begun shifting east of our longitude as trough across the west gradually deepens with system in Pacific Northwest coming onshore. Surface cold front that passed south through our CWA this morning will keep temps mostly in the 70s for our area with portions of our southernmost counties topping out in the low 80s by late this afternoon.
329 PM CDT Sun Oct 30 2016 (Tonight and Monday) Going with a dry forecast the next 24 hours as upper level high pressure ridge continues to bring warm and dry weather.
235 PM EDT Sun Oct 30 2016 A cold front will cross the region late tonight into early Monday. High pressure will rebuild over the area through the middle of the week.
As of this writing, SDF is within one degree of the high temperature record for the day. Through the remainder of this afternoon and this evening, a cold front will push into the area. Showers have begun to develop further to the west along the cold front towards Indianapolis this afternoon. Halloween will feature cooler temperatures, particularly across southern IN and north central KY where highs will top out in the upper 60s to lower 70s. Monday night will be warmer again as winds shift to southerly and upper level ridging builds back in.
Given the current profiles, do not think winds will propagate east onto the lower elevations. Stronger winds will gradually decrease over the mtns while at the same time surface winds will increase over the lower elevations. Monday evening and overnight, we will likely see some lingering gusty winds across the higher terrain and adjacent territory during the evening. Any snow accumulations across the highest terrain will be isolated and very light.
314 PM EDT Sun Oct 30 2016 A cold front will push south through the area today and tonight, bringing a chance of showers. As high pressure travels east through the Great Lakes Monday into Monday night, the old frontal boundary will move back northeast as a warm front. Surface cold front is currently pushing through the CWA and is just past KDAY with a weak line of showers out ahead. As this happens Monday the cold front that was just south of the area will stall and wash out. As this happens a warm front will slowly pull north as well.
258 PM EDT Sun Oct 30 2016 High pressure will build into the region tonight, allowing temperatures to fall to between 35 and 40 degrees.
Low pressure off the Oregon coast is providing easterly upslope flow into the Cascades where an abundance of lower level moisture combined with the upslope lift has resulted in light rain. A very moist warm front will develop along the WA/OR border around 00Z and move north to the Canadian border by 12Z Monday.
152 PM EDT Sun Oct 30 2016 High pressure will remain over the Southeastern U. today ahead of a dry, back door cold front that will move south through NC Monday. Afternoon temps in the lower-mid 80s, which is 10-15 degrees above normal. Surface cold front associated with this feature will traverse southward across the Mid-Atlantic late today/tonight, and enter our northeast counties just prior to daybreak.
100 PM CDT Sun Oct 30 2016 A cold front will exit southeast KS early this morning leaving widespread stratus in it's wake. Low clouds are expected to mix out toward mid day but an airmass change will keep temperatures closer to climate normals with highs ranging from the mid and upper 60s across portions of central KS to the lower 70s near the OK state line. Light east-northeast winds will return to the south becoming breezy across central KS late tonight as low pressure deepens over the Northern High Plains. Breezy southerly winds will spread east across the area on Monday helping to drive temperatures back into the low to mid 80s and a few records may fall once again.
