Higher elevations, above the inversions, will see warmer temperatures as is always the case this year. A few high clouds will move overhead Wednesday with the only change being upper level winds becoming more southwesterly which will usher in warmer temperatures. For the most part though, high temperatures should be a little warmer than seen over the last few days. High pressure will be shifting east as the next long wave trough moves onshore.
Temperatures are on a slow rebound as a ridge of high pressure attempts to build across the southern CONUS. As the ridge of high pressure settles over the southern CONUS on Wednesday, a weak disturbance to the southwest will set up and a low level 850 jet out of the southwest will be in place over the Panhandles allow breezy winds to mix down to the surface. As the ridge shifts further east upper level flow will be out of the southwest, with continued dry air over the Panhandles, the aforementioned disturbance providing the low level 850 jet will still be positioned out of the southwest, but will be stronger.
1215 PM EST Tue Jan 23 2018 Cold front will move offshore this afternoon with breezy conditions into this evening.
Things starting to wind down for this short term period as our upper level trough lifts off to the northeast but still a little weather to deal with first. No accumulation across valley locations with trace amounts up to a few tenths of an inch of snow possible across the highest peaks. Breezy conditions remain until late in the night when the trough begins to lift out. Though the trough begins to exit, residual moisture will hang around and result in cloudy conditions through the night, especially across areas north of I-40. Highs will in the lower 40s to upper 40s.
/ Issued 537 AM CST Tue Jan 23 2018/ Low pressure will pull away from Arkansas today and allow high pressure to build into the area. Today Through Wednesday Night Low pressure will continue to move northeast away from Arkansas today. High pressure will build into the area. The high pressure will bring clear skies to the area today through Wednesday. The clouds in the north this morning will dissipate as the low moves away. After lows in the upper 20s to lower 30s tonight, lows will be in the lower 30s for Wednesday night.
Wednesday will be similar to today, though generally a few degrees cooler across the region.
A cold front will move south of the area this evening.
245 PM CST Tue Jan 23 2018 Surface and upper ridge to maintain dry conditions through the remainder of the work week.
235 PM CST Tue Jan 23 2018 A weak mid level trough and associated vort max will move through the area late tonight and tomorrow morning. Some models are dry with this trough and some produce very little qpf. However, in this kind of environment in the winter, weak troughs with a mid level vort max, and some lower level cloud cover can easily wring out some scattered flurries.
Weak high pressure near Grand Forks at 09z. Drier air around the storm to our east clearing the low clouds southwestern from NE into central MN and the western edge of clearing is pushing into the far SE fcst area (Park Rapids/Wadena and may get into Bemidji for at time this morning). Models continue to paint some light precip stretching from the low southeast thru southeastern Manitoba and into far NW Minnesota as we head toward early evening.
Lows are expected to be in the mid to upper teens across far west central KS, to the lower 20s across south central KS. On Wednesday, large scale ridging will spread out across the Rockies into the western Great Plains, leading to lee trough development. Warming lower tropospheric temperatures are expected as a result of the approaching ridge, with 850mb temperatures reaching +5 to +8C.
High pressure starts a strong warming trend this afternoon, continued into mid week, with dry conditions and breezy winds at times.
247 PM CST Tue Jan 23 2018 (Tonight and Wednesday) High pressure over the region will keep conditions quiet across West Central Texas tonight and into Wednesday. Highs will be in the lower to mid 60's with light southeasterly winds in the afternoon.
927 AM MST Tue Jan 23 2018 Current surface analysis shows low pressure over southeast SK, with a frontal boundary well north and east of the region. Upper level analysis shows Low pressure over the western Great Lakes region, with a ridge along the west coast.
1127 AM CST Tue Jan 23 2018 Updated weather grids earlier in the morning to account for more cloud cover, and just slightly cooler temps in some spots. Models are in agreement large scale flow will be somewhat progressive the next several days with increasing heights/upper ridge building in from the west. However, to what degree will snow cover inhibit the potential for warmer conditions.
Today Through Wednesday Night Low pressure will continue to move northeast away from Arkansas today. High pressure will build into the area. The high pressure will bring clear skies to the area today through Wednesday. The clouds in the north this morning will dissipate as the low moves away. After lows in the upper 20s to lower 30s tonight, lows will be in the lower 30s for Wednesday night.
908 AM PST Tue Jan 23 2018 Dry and warmer weather will continue through Wednesday.
912 AM PST Tue Jan 23 2018 Offshore flow and a building upper level ridge will bring a few days of substantial warming to the region.
351 PM CST Tue Jan 23 2018 A broad low pressure system continues to push east northeast out of the region. A look at recent satellite trends show the low clouds slowly eroding from the southwest in central and southeast Missouri. An upstream short wave trough will rotate around the base of the broad trough and will provide a chance for snow flurries early Wednesday morning over parts of northeast Missouri and westhern Illinois. It will be warmer tomorrow with highs in the 40s with southwesternly winds.
322 PM EST Tue Jan 23 2018 A trough of low pressure will move east across the area tonight as a low pressure system moves from the central Great Lakes to Maine.
Very quiet conditions continue as high pressure is settled over the state. By Wednesday afternoon/evening, high pressure ridge will start to slide east of the state allowing for a more easterly flow into the area. Low temperatures tonight should be slightly warmer than last night, but much of the west/north could dip into the upper 30s. Highs tomorrow just a bit cooler, in the mid 60s.
Models indicate that northwest flow aloft will relax and transition to a more westerly flow over the next 24 hours, as a ridge of high pressure gradually slides east and approaches Colorado. Expect generally lighter diurnal winds with dry conditions and slightly warmer temps. Highs are forecast to be in the 30s to near 40F for the high valleys, and in the 40s across the plains.
250 PM EST Tue Jan 23 2018 A cold front will exit central NC early this afternoon.
Later this week, an upper level ridge will begin pushing into our area Wednesday night as a trough over the Pacific reaches the west coast, enhancing the downstream ridge and pushing it east.
We have trended the forecast toward the cooler guidance numbers.
1153 AM EST Tue Jan 23 2018 Cold front will move offshore this afternoon with breezy conditions into this evening.
1251 PM EST Tue Jan 23 2018 Low pressure will track across the Central Great Lakes this morning dragging a cold front across the forecast area. Cold front is well east of the area at this time. Colder air is slowly spilling into the region and temperatures are holding steady in the lower 40s in the east and upper 30s in the west half of the area. Low pressure centered over Lake Huron with the leading edge of the cold front just east of Erie PA. Models in good agreement tracking the low into SE Quebec by this evening, which is in line with current ht falls centered over SW Quebec. Can pick up a few inches overnight but should come to an end quickly Wednesday as high pressure builds in from the west.
1035 AM CST Tue Jan 23 2018 Some clouds linger across northwest AR and far northwest corner of OK this morning, but should clear off soon as upper low continues lifting northeast. This leaves us with a sunny and slightly warmer afternoon. As a result, a sunny day is expected across eastern Oklahoma and western Arkansas with high pressure building across the area at the surface.
At 18Z, the cold front was just east of a line from Valdosta, GA to Perry, FL.
132 PM CST Tue Jan 23 2018 An upper level ridge will translate across the southern high plains Wednesday and Wednesday night.
1135 AM EST Tue Jan 23 2018 Anticipate mvfr cigs with scattered mix of light rain/snow showers changing to light snow showers as secondary cold front settles southeast through the area with passage of upper wave. Winds will be gusty today, but strongest winds will be in southwest flow in advance of cold front with a rather quick diminishing trend into the evening. There remains a window for rain to mix with snow mid-late afternoon as temperatures drop with the cold frontal passage.
/issued 256 AM CST Tue Jan 23 2018/ Weak troughing beneath an upper ridge over the region will keep quiet weather conditions in place.
335 AM CDT Wed Jul 5 2017 Upper low currently over southwest Missouri will track slowly E/NE into the lower Ohio River Valley today. Thanks to temperatures climbing into the lower to middle 80s and dewpoints in the upper 60s/lower 70s, CAPEs will reach the 1500-2000J/kg range by peak heating. Despite decent instability and increasing synoptic lift ahead of the approaching upper low, winds throughout the profile will remain very weak. Have focused highest PoPs across the southeast CWA in closer proximity to the low. Showers and thunderstorms will linger along/south of the I-70 corridor into Thursday as the upper low tracks through Kentucky. Meanwhile, a cold front poised over the Upper Midwest will trigger scattered strong to severe thunderstorms across Wisconsin/Minnesota late Thursday afternoon and evening.
329 AM CDT Wed Jul 5 2017 Upper level low will slowly move across the area today into early Thursday. The GFS looks a bit more consistent with the movement and position of the low so have pretty much followed it.
Drier conditions are likely today and tonight as a broad upper level high pressure center across the Intermountain West begins to expand slowly eastward into the Western High Plains. With little change expected to the air mass across the high plains, look for highs to the push the lower to mid 90s(F) this afternoon. Drier conditions are likely to continue across western Kansas through late Thursday as an upper level high pressure center remains stretched across the Intermountain West into the Western High Plains.
311 AM EDT Wed Jul 5 2017 An upper level low will track slowly east across the Mississippi river valley tonight and gradually approach the Appalachians from the west late Thursday into Thursday night. The general upper air pattern for this part of the forecast will be characterized by high pressure over the four corners region of the U. with a gradually deepening trough over the east coast.
In the mid and upper levels of the atmosphere northerly flow continues as wind is funneled down between the high pressure over the Rockies and a trough of low pressure over Missouri. Most areas will see highs in the mid to upper 90s allowing afternoon heat index values to top out above 100 degrees as southerly flow at the surface maintains the low level moisture across South Central Texas.
Expect slightly warmer than normal across interior areas, and cool and cloudy conditions along the coast. remains firmly entrenched in a stagnant blocking pattern. Across the intermountain west, a large region of high pressure has gradually built up within the past couple of days, and is not expected to move anywhere for the foreseeable future. Meanwhile, a corresponding large trough of low pressure has dug into the north Pacific, and is also not expected to move much over the next several days. This period of light winds and low seas will gradually come to an end as a thermal trough intensifies across the interior and north winds redevelop and strengthen Thursday into this weekend.
Ridge axis of high pressure over the west Atlantic will remain near to north of the Cape, with a relatively light east- southeast low level flow across the region.
114 AM EDT Wed Jul 5 2017 High pressure over the eastern Great Lakes will provide fair weather across our area today. There is a slight chance of thunderstorms tonight and Thursday as a low pressure system moves east through the Ohio Valley.
540 AM CDT Wed Jul 5 2017 A closed area of low pressure in the low and mid levels of the atmosphere will continue to drift east today and tonight across the Missouri Ozarks. The low should begin to accelerate a bit late tonight as an upper level jet core punches south through the Plains and begins to kick the low east.
258 AM CDT Wed Jul 5 2017 Low level moisture, instability and many outflow boundaries will combine with an upper level short wave trough moving south across the Texas Panhandle this afternoon and evening to produce another round of showers and thunderstorms. It appears at this point that the best chance of rain will be across the southern Texas Panhandle ahead of the short wave trough. Thursday may be a dry day as the upper level high builds move over Colorado which leaves the panhandles in a less favorable northeast flow for showers and thunderstorms.
335 AM EDT Wed Jul 5 2017 High pressure will provide fair weather today into this evening. There is a low chance for showers on Thursday southeast of US 24 as weak low pressure tracks through the Ohio Valley. Most locations will remain dry with highs in the low to mid 80s both today and Thursday.
Weak upper ridging over the area will provide an ideal evening for viewing fireworks for the vast majority of us. The PacNW lies beneath south flow aloft between high pressure over the Rockies and low pressure in the Gulf of Alaska.
152 AM CDT Wed Jul 5 2017 A closed area of low pressure in the low and mid levels of the atmosphere will continue to drift east today and tonight across the Missouri Ozarks. The low should begin to accelerate a bit late tonight as an upper level jet core punches south through the Plains and begins to kick the low east.
332 AM EDT Wed Jul 5 2017 High pressure will build across the region today and then move east tonight. The high will remain east of the region through Thursday. Fine summer weather can be expected as high pressure builds across the region today and then slides east and off the coast tonight. Expect plenty of sunshine today along with warmer afternoon temperatures. Highs this afternoon will range from the upper 70s to low 80s across the region but a bit cooler along the immediate coast. Expect mainly clear skies tonight as the high continues to move east. Sct shwrs and isold tstms from this system will begin to impact msly Nrn and Cntrl ptns of the FA late in the day Thu and cont thru Fri as the remnants of a weak cold front moves SE and then stalls ovr the FA.
215 AM EDT Wed Jul 5 2017 A frontal boundary stalls across the area through Thursday with several waves of low pressure moving east along it.
157 AM EDT Wed Jul 5 2017 Typical summer pattern will persist this week with Bermuda high pressure extending from the Western Atlantic into the Gulf of Mexico and a lee-side trough in the forecast area. The upper ridge, to our south and east, will build northward some over the forecast area. Models continue to indicate a strong ridge over the W CONUS, with upper trough deepening and shifting east into the E CONUS.
439 AM EDT Wed Jul 5 2017 High pressure will remain over the region for one more day, dry seasonable weather continues. High pressure will crest over the region today and begin to slide eastward this afternoon. Minimum temperatures will be a bit warmer with increasing humidity also, generally upper 50s to mid 60s. Temperatures Thursday will be a bit warmer than normal and close to Wednesday temps.
However, additional MCS activity is expected to form in the high plains overnight, which may be able to affect extreme southwest sections during the early morning hours.
409 AM EDT Wed Jul 5 2017 High pressure will remain over the region for one more day, dry seasonable weather continues. High pressure will crest over the region today and begin to slide eastward this afternoon. Minimum temperatures will be a bit warmer with increasing humidity also, generally upper 50s to mid 60s. Temperatures Thursday will be a bit warmer than normal and close to Wednesday temps.
354 AM EDT Wed Jul 5 2017 A weak cold front will sink south of the area through morning and remain just south of the area into Thursday.
345 AM CDT Wed Jul 5 2017 An upper ridge currently extends from the western Atlantic to the western Gulf of Mexico. A weak trough has moved into the Central Plains and will slide into the mid-Mississippi Valley today. The relatively close proximity of that trough to the ridge overhead of the CWA will weaken the high pressure's subsidence. The general trend of slowly transitioning back to a wetter pattern will continue into the rest of this week as the weaker trough to the north slowly merges with another.
305 AM CDT Wed Jul 5 2017 Fairly quiet early this morning with high pressure remaining in control across the Great Leaks/Upper Mississippi River valley region. For today, will be watching a weak mid-level trough pass through southern Ontario/northern WI with increasing moisture plume filling into our area.
305 AM EDT Wed Jul 5 2017 High pressure will retain control through Wednesday, providing the region with generally rain-free weather, pleasant temperatures, and fairly low humidity levels.
300 AM EDT Wed Jul 5 2017 High pressure over the area will gradually shift offshore today. As the high moves offshore, a southerly flow will introduce gradually more humid air into northern New England through the remainder of the week.
Otherwise, a strong ridge of high pressure centered over the Four Corners region will bring dry weather and above normal temperatures to the district for the next several days. Today's weather will be driven by high pressure, southerly flow aloft, and the upper-level disturbance off the central CA coast. Otherwise, we anticipate mainly dry, or high-based thunderstorms to develop this afternoon over inland central California, with the best instability over the higher elevations of the southern Sierra Nevada.
331 AM EDT Wed Jul 5 2017 A frontal boundary stalls across the area through Thursday with several waves of low pressure moving east along it.
Broad high pressure over the Gulf will support a continuation of light to moderate southeast winds through Wednesday, with few to scattered early to mid morning low clouds, before low cumulus streets and a weak sea breeze develop by afternoon. 500 mb high pressure centered northwest of Deep South Texas and the Rio Grande Valley over the Four Corners area will be nudged slightly northwest by 500 mb low pressure over the central United States and an inverted 500 mb trough over the central Gulf of Mexico that will approach from the east.
346 AM EDT Wed Jul 5 2017 High pressure centered just north of Lake Ontario will drift east into New England today. A weak trough will develop across northeast Ohio and northwest Pennsylvania this afternoon as low pressure across the Ohio valley deepens and track northeast into the region Thursday.
340 AM EDT Wed Jul 5 2017 Warm/humid airmass to persist in the short term as regime stays in the SW mean fetch with a closed upper trough west of the TN Valley and the typical summertime Bermuda high off the Southeast coast. The aforementioned trough is progged to dampen gradually and approach from the NW today into Thursday, which will allow the CWA to be susceptible to multiple impulses traversing the weak flow in the more enhanced moisture field. Temps for most locations in the upper 80s north to mid 90s SE coupled with the unwelcome dewpoints in the low 70s will result in afternoon heat indices of upper 90s to low 100s.
645 AM EDT Wed Jul 5 2017 Typical summer pattern will persist this week with Bermuda high pressure extending from the Western Atlantic into the Gulf of Mexico and a lee-side trough in the forecast area. Upper level ridge building and moisture shallow. Upper level ridge continues over the southeastern states through Thursday which should limit afternoon convection and temperatures in the upper 90s. Upper ridge shifting southeast into the Atlantic as long wave trough moves into the eastern CONUS.
A much better chance for storms comes later tonight as a weakening cold front moves in from the Dakotas. Models are in good agreement that a strong trough associated with northern Alberta upper low will swing across MN/WI on Thursday.
127 AM EDT Wed Jul 5 2017 High pressure will retain control through Wednesday, providing the region with generally rain-free weather, pleasant temperatures, and fairly low humidity levels. High pressure slides to the east and allow a slow return of moisture to the area. Initially, best moisture return is over western NY as the low level southwest winds comes up along the lake plain.
348 AM MST Wed Jul 5 2017 Temperatures will remain above normal through this week as a strong high pressure system will dominate the area. An upper level ridge of high pressure is currently centered over the Four Corners with moisture from northern Mexico rotating up into southern Arizona and SE California.
646 AM EDT Wed Jul 5 2017 High pressure centered just north of Lake Ontario will drift east into New England today. A weak trough will develop across northeast Ohio and northwest Pennsylvania this afternoon as low pressure across the Ohio valley deepens and track northeast into the region Thursday.
SHORT TERM (Today through Thursday): South Texas comes under the influence of a Col over the next few days with High pressure to the west and east and lower pressure to the north and south of the region. Gulf moisture gradually increases and deepens the next 36 hours, however high pressure will continue to dominate today with little to no forcing for any significant convection.
347 AM CDT Wed Jul 5 2017 An upper level low centered over Missouri this morning will gradually slide east into Illinois and Indiana by this afternoon. Simultaneously, strong ridging will develop across the western US (where the heat will be on). Jones Upper level ridging will give way to a developing and seemingly persistent trough that will envelope the region during the latter half of the week. High pressure across the northwestern gulf will keep winds light out of the south.
410 AM EDT Wed Jul 5 2017 High pressure will provide another pleasant day with seasonal temperatures, low humidity and generally rain-free weather.
340 AM MDT Wed Jul 5 2017 High pressure centered over the Four Corners will keep temperatures well above normal for this time of year. 700mb temps will hover near or just below 20 C each afternoon which translates to near triple digits persisting in the lower valleys through at least the weekend. weak disturbances will rotate around the high pressure in place, and these may pull some moisture under the ridge axis. A few afternoon showers and thunderstorms will once again develop in the higher terrain.
WV imagery indicates a broad upper level ridge of high pressure building across the Intermountain West. Near the surface, a weak lee side trough of low pressure remains anchored near and along the Colorado border. Recent temperature trends have been slower to warm this afternoon, and as as result the highs have been gradually adjusted downward only a few degrees. Large upper high and ridge remaining anchored across the central Rockies/Great Basin area during the latter half of the week into the weekend; a pattern suggestive of high CAPE and low shear/weak steering flow for any convective development. Light southeasterly winds will persist across southwest and central Kansas through Wednesday as a weak lee side trough of low pressure remains anchored near and along the Colorado border.
Otherwise, expect dry and seasonable weather along with a warming trend from Thursday into the weekend as high pressure strengthens.
