Dry weather continues through the period as high pressure remains in control. Eastern CONUS ridge will persist through the weekend.
Early this morning a deep area of low pressure was centered over east-central Saskatchewan with a cool front extending south and west across northwest North Dakota and eastern Montana. A pre- frontal trough led the cool front and was found over central North Dakota. An area of cirrus ahead of the trough will spread eastward into north- central and central Minnesota this morning. Temperatures will be a bit cooler over north- central Minnesota where the front will arrive first.
The highest winds will be found in the higher terrain areas of southeast Minnesota and northeast Iowa. A Canadian cold front will move through the region late this afternoon and evening.
Little change seen for Sunday as the CWA remains on the front side of the upper high centered over Utah with northwesterly flow over the area.
On Sunday, the next upper level disturbance and associated weak cold front will drop south into northern Wisconsin.
858 PM CDT Sat Jul 8 2017 High pressure centered right over central Illinois this evening bringing pleasant weather conditions to the region with dew points much more tolerable today. The latest ILX sounding continues to exhibit a very dry air mass in the low to mid levels of the atmosphere, so the wave to our northwest will have a tough time producing any significant precip in our area overnight.
831 PM EDT Sat Jul 8 2017 A cold front will stall over the coast later tonight and Sunday. High pressure will build aloft over the region early to mid week bringing hot temperatures. Additional storms along the northern Piedmont are with the cold front and are not currently as strong.
940 PM EDT Sat Jul 8 2017 Earlier start and higher coverage of storms today as moisture returned and low level ridge axis shifted a bit south. Low-level ridge axis near Lake Okeechobee.

That's around the periphery of the anticyclone's circulation, centered over the heart of the Show Me land, which slowly migrates eastward and centers/ridges itself broadly across the Ohio and Tennessee river valleys tmrw.
716 PM EDT Sat Jul 8 2017 Dry conditions will continue tonight through Sunday as a ridge of high pressure settles across the area. This high will shift to the east Sunday night allowing moisture to be drawn back northward.
High resolution models continue to indicate a bit stronger southerly winds across the higher elevations near the Nevada border tonight, as outflow from the Nevada storms continues to move north, so we increased winds south of the Snake River Plain overnight. Otherwise, cloud cover overnight will likely keep low temperatures up, and temperatures tomorrow should only be a degree or two cooler than today, so continuing the Heat Advisory looks good.
1243 AM EDT Sun Jul 9 2017 Dry conditions will continue tonight through Sunday as a ridge of high pressure settles across the area. This high will shift to the east Sunday night allowing moisture to be drawn back northward.
Proton Previous Discussion: Tonight and Sunday: High pressure is forecast to persist across the area through Sunday with continued warm to hot temperatures continuing.

Also, lowered overnight lows as svrl ob sites showed rain cooled air in the lower to mid 70s remaining steady thru sunset. /issued 231 PM CDT Sat Jul 8 2017/ Nw flow aloft continues across our region again today, as the upper ridge remains anchored over the wrn CONUS and an upper trof lingers over the ern CONUS. Upper ridge to begin nudging ewd in the wake of the E Coast trof, as we move into the new work week. Under the influence of the ridge, temps will likely begin to inch upwards into the mid 90s areawide by mid to late work week.
Otherwise, hot weather will begin to build across Mid- America Sunday, as upper level high pressure builds in from the west, with 90s to near 100 degrees expected, warmest across central KS.
The convective activity will decrease in intensity after sunset, but could linger well into the evening hours due to an approaching upper level short wave trof. Drier air has worked into northwest Alabama behind a 925mb trof, and this drying trend will continue moving southward overnight. An amplified pattern continues for the second half of the weekend with ridging over the Western US and a trough through the Great Lakes and Central Appalachians.
A few showers and thunderstorms are possible late Sunday afternoon and Sunday night as low pressure moves southeast along the front toward central Lower Michigan.
Farther south toward DTW, the influence of high pressure in the Ohio valley will hold through the period. Quite through the afternoon and overnight as passing mid level trough axis continues to usher cool and dry air in to the region. A broad trough has set up across much of the Midwest and Great Lakes with generally weak flow throughout the trough. On that note, a cold front currently dropping through Ontario with a line of convection will slow forward progress as it reaches northern MI Sunday.
The western extent of the Bermuda Ridge extended across the southern Gulf of Mexico- with a weakness in the ridge over the eastern Gulf. Our forecast area was south of the base of an upper trough, with the Q-G forcing associated with this trough to our north.
(Sunday Night through next Saturday) An upper level height ridge, over the Four Corners region at the beginning of the week, will expand east across the southern Plains and much of the southern CONUS through the middle of the week.
Drier air will continue to filter into the region in the wake of today's weak cold front, basically bringing an end to rain chances across the CWA. /issued 240 PM CDT Sat Jul 8 2017/ Weak cold front now near the TN/MS border will continue to push through the CWA by mid evening.
The higher dew points were near the international border adjacent Santa Cruz/Cochise Counties.
717 PM EDT Sat Jul 8 2017 A cold front will push east through the region today and offshore overnight.
Upper level ridging will remain over the region through Sunday.
As of 230z, a Bermuda ridge was located off the southeast coast with a stout ridge out west centered over Utah. A mean trough is located over the eastern half of the country with a deep cold core low over the Hudson Bay. Highs will reach the low 90's. In general, the weather pattern for this week will feature the eastward movement of the upper level trough currently over the region and an expansion of an upper level ridge. The cold front that remains situated just to the north of my CWA this afternoon will eventually move through the region.
Rain chances will likely drop significantly by Mon as heights increase with an expanding upper ridge from the west. A few showers and storms may be possible on its southern/SE periphery Tue as a mid to upper trough slides westward over central TX. Otherwise, expect a drying trend with regards to precip through most of the week as the upper ridge expands over the central CONUS.
1016 PM EDT Sat Jul 8 2017 A cold front will push east through the region today and offshore overnight.
741 PM EDT Sat Jul 8 2017 With any lingering showers ending in the evening, weak high pressure will yield a pleasant second half of the weekend.
The cold front which brought yesterday evening's showers and storms has pushed southeast of the state into SW VA and NE TN. High pressure will bring dry mild weather for Sunday. At the beginning of the week there will be an extensive ridge over the western U. with troughing in the east. As the week progresses the ridging in the west dampens somewhat and bridging from the Bermuda High and the western ridge takes place. This results in a flatter more zonal pattern for the middle of the week, before the western ridge amplifies again and troughing reasserts itself in the eastern U.
752 PM EDT Sat Jul 8 2017 A shower or thunderstorm will be possible in spots across southern Pennsylvania this evening before drier, less humid and slightly cooler air arrives tonight. Clearing skies expected after sunset, as high pressure and associated drier air mass builds into the region. Radiation cooling resulting from the light wind, clear skies and drier air should result in the coolest night in about 10 days, with min temps ranging from the upper 40s over the northwest mountains, to the low 60s over the Lower Susq Valley.
On the larger scale, a 596 decameter ridge will remain anchored over the Four Corners region, extending southeast into texas. High temperatures Sunday will be a couple of degrees warmer than today due to decreasing rain chances and less cloud cover.
Upper level ridge was located over the Rockies with a short wave over eastern ALTA. Upper level ridge will shift east over the forecast area and flatten by Tue morning. Upper level low over the northeast Pacific will also move east and follow the upper low.
708 PM EDT Sat Jul 8 2017 SE Michigan will be in between high pressure over the Ohio valley and the next front over the northern Great Lakes tonight. VFR in a mix of high clouds will slide over the region from the frontal zone while cooler and less humid air settles in at low levels and allows cumulus to fade around sunset. Quite through the afternoon and overnight as passing mid level trough axis continues to usher cool and dry air in to the region. A broad trough has set up across much of the Midwest and Great Lakes with generally weak flow throughout the trough. On that note, a cold front currently dropping through Ontario with a line of convection will slow forward progress as it reaches northern MI Sunday.
There could be an isolated shower across Southwest Virginia and another over the extreme Southeast Tennessee and Southwest North Carolina as a weak trailing trough slips southeast across the region.
High pressure over the central Atlantic will drift northward over the next several days.
The 00z sounding depicted an unstable and moist atmosphere, although some drier air had worked into the lower and mid levels when compared to the sounding from this morning. Southwest to west winds were observed in the lowest levels while northwest flow prevailed from around 900 mb to 450 mb. /issued 345 PM CDT Sat Jul 8 2017/ High pressure at the surface continues to reside over the northern Gulf of Mexico.
1106 PM EDT Sat Jul 8 2017 High pressure will build into Pennsylvania from the midwest tonight and Sunday.
While temperatures are a couple of degrees cooler than yesterday. but the lower dewpoint temperatures have made things much more pleasant. An upper level ridge is currently situated over the Intermountain West while a surface front extends from northern Mississippi across central Arkansas into southern Oklahoma. High pressure will begin to set up over the southeastern states on Sunday. The upper low over the Rockies will begin to flatten out across the Plains into the early part of the week. Increase in moisture combined with high pressure parked over the area will result in heat index values in the mid to upper 90s across most of the area.
Coulston Upper level ridging will remain over the region through Sunday.
Highs will reach the low 90's. In general, the weather pattern for this week will feature the eastward movement of the upper level trough currently over the region and an expansion of an upper level ridge. The cold front that remains situated just to the north of my CWA this afternoon will eventually move through the region.
/issued 240 PM CDT Sat Jul 8 2017/ Weak cold front now near the TN/MS border will continue to push through the CWA by mid evening.
Quiet weather is expected tonight into Sunday morning across the area, as high pressure passes by to the southwest.
/issued 125 PM CDT Sat Jul 8 2017/ Upper ridge centered over the 4 Corners region this morning extends eastward across TX to the Gulf. This ridge will expand and contract over the coming week but remain entrenched over the west.
High pressure will keep it dry through the weekend.
High pressure will ridge across the state with the ridge axis across the southern half of the area allowing for some light southwesterly flow across the Nature coast, and S/SE flow elsewhere. Winds and seas will be light through the period with high pressure ridging across the waters.
A short wave trough coming over the western upper level ridge will ride southeast into the eastern part of our region into Sunday evening. At the surface, a low pressure area/trough and cool front will be pushing into our region. Until then, conditions should be ideal for a big warm up on Sunday with all models showing 925h temperatures rising into the lower to mid 30s C across central and north central South Dakota.
1038 PM EDT Sat Jul 8 2017 High pressure will build into Pennsylvania from the midwest tonight and Sunday.
613 PM CDT Sat Jul 8 2017 Increasing heat and humidity are on tap for the week ahead as upper-level ridging builds eastward and the thermal ridge axis bulges into the central and then eastern Plains.
/issued 414 PM EDT Sat Jul 8 2017/ Latest IR imagery from this afternoon shows broad troughing over the Tennessee Valley and an elongated upper level high pressure ridge over the Western Atlantic waters, near Bermuda. The flow pattern into South Florida is from the south southeast, with the region currently sandwiched between the influence of the Bermuda high and a weak upper level low in the eastern Gulf. With high pressure dominating near Bermuda from early to mid week, rounds of increased moisture will advect over the peninsula from the southeast through the period.
Broad mid-level trough axis extending from the Great Lakes region down to the Gulf Coast drifts fairly slowly eastward today through Sunday. Temperatures will again be able to reach the low 90s for our inland areas with max temps in the high 80s near the coast. Minimum temperatures will be near seasonal average in the low 70s.
927 PM MDT Sat Jul 8 2017 Weak wave rounding high pressure over the region was producing isolated showers and thunderstorms over the area this evening.
921 PM EDT Sat Jul 8 2017 Dry and less humid weather is expected Sunday under high pressure. Otherwise, mainly clear skies are expected under building high pressure.
This process will continue for the next several days, the only real changes being subtle shifting of the ridge position each day, which will eventually alter our steering flow. Cooler temperatures and increased low level moisture are expected through the weekend, though gusty and erratic outflow winds should still be anticipated.
Mostly-disorganized convection earlier this afternoon focused across northeast Alabama over the last 1-2 hours thanks to the arrival of the main trough axis in an environment with greater moisture (satellite-derived precipitable water values still 1. Minor adjustments are forthcoming to hourly grids based on new data but it should still be a cooler and drier night than anything seen in the last week or so.
/issued 231 PM CDT Sat Jul 8 2017/ Nw flow aloft continues across our region again today, as the upper ridge remains anchored over the wrn CONUS and an upper trof lingers over the ern CONUS. Upper ridge to begin nudging ewd in the wake of the E Coast trof, as we move into the new work week. Under the influence of the ridge, temps will likely begin to inch upwards into the mid 90s areawide by mid to late work week.
545 PM MDT Sat Jul 8 2017 The upper high has shifted from the 4Corners to SW Utah over the past 24 hours according to this morning's H500 hand analysis. Sunday the high shifts back toward the 4Corners region by the afternoon with lighter winds returning aloft.
1018 PM EDT Sat Jul 8 2017 A cold front continues moving offshore tonight.
Expect partly cloudy skies for the tonight period mainly across the eastern half of the area with overnight lows in the low to mid 70s most areas. There will be better chances for rain on Sunday as a strong sea breeze activity is expected and a back door cold front/boundary pushes down into the eastern half of the area.
The best chance will be over the eastern plains where a small theta-e ridge will be.
619 PM CDT Sat Jul 8 2017 Quiet weather will continue through tonight as high pressure gradually slides to the southeast.
The most robust convection should be west of a line from Central City to Red Cloud, where the RAP shows the highest corridor of instability along with ~30 kts of bulk shear.
1230 AM EDT Sun Jul 9 2017 A cold front will push east through the region today and offshore overnight.
Elsewhere a low pressure system that brought the winter pcpn was moving away from the region and the showers will lessen overnight. Temperatures are expected to fall below freezing and into the lowers 30s in the basin with 20s elsewhere.
More Snow and Wind for the Mountains with More Wind & Elevated Strong westerly winds gusting to near 40 mph and dry air will continue to the high fire danger across the plains this evening. Wind gusts over 50 mph will be possible in and near the high country overnight. Wind gusts over 50 mph will be possible in and near the high country. Temperatures on Thursday will be a little cooler than today but still well above average for mid February. However, late in the day, a cold front will drop south across northern El Paso County and the Palmer Divide, resulting in falling temperatures and winds shifting out of the north.
This lowered amounts to generally 1-2 inches along and north of the Hwy 200 corridor. Current surface analysis places low near Winnipeg, with cold front stretching off to the west near the international border. Upper level analysis places trough stretching from northern Manitoba towards the Pacific northwest, with potent wave sliding across the Canadian plains into the northern plains. For the rest of this afternoon into this evening, cold front will continue to settle to the south with snow gradually developing from north to south.
242 AM EST Thu Feb 15 2018 A weak trough of low pressure and its accompanying rain will exit the coast early today.
There is growing concern that some of the lower elevations, from Laramie to Rawlins and areas south of I-80 may see some travel impacts by early Thursday morning as one quarter mile visibility and heavy snow has been reported at Elk Mountain in the last 10 minutes. Activity looks pretty isolated for now, but if the snow begins to impact a larger area, may need Winter Weather Advisories for the lower elevations of Carbon and Albany counties.
1158 PM EST Wed Feb 14 2018 A weak disturbance will keep light rain chances through this morning before low pressure and a cold front results in widespread rain later today and tonight.
Frost is developing for many locations due to warmer temperatures just off the surface and colder temperatures from below. BMickelson Previous discussion: Fast westerly jet over Montana with strong winds occuring across the ridge tops and high terrain areas. Upper trof dropping through the Pacific Northwest today will drag a cold front south across the state.
321 AM EST Thu Feb 15 2018 A warm front will keep light rain chances through this morning before low pressure and a cold front results in widespread rain later today and tonight.
Meanwhile, a strong cold front stretching from northwest MN to central MT as of 08z will advance south today, reaching northeast NE this afternoon.
By late day into Thursday evening, a cold front will settle south, reaching about the Ohio River by Midnight Thursday night.
Cold front works south across the area on Thursday. Cold air lags behind the front, but once the cold air advection develops in the low levels, winds should increase driving wind chills into the single digits and teens.
Although a rather robust southwest flow aloft will intensify across the region through much of the period, a lack of mid/upper level moisture will hinder precip chances across the high plains of western Kansas. Well above normal temperatures are likely again today as a west- northwest downslope flow reinforces the warmer air mass ahead of an approaching cold front expected to arrive later this afternoon.
1051 PM CST Wed Feb 14 2018 Tonight through Thursday we will see a cold front currently near the international border sag south through the area with little fanfare. In the longer term the main story will be a significant change in the large scale flow pattern across the continent, with fairly zonal flow becoming much more amplified as an upper trough sets up across the west and ridging takes hold over the east.
435 AM EST Thu Feb 15 2018 A robust, deep layer mean anticyclone dominates the atmosphere over the entire Gulf basin, southeastern United States, Bahamas, and northwestern Caribbean Sea. In addition, an ever-so- slightly cooler and drier air mass has advected into the service area. Current air temperatures in most Keys island communities are holding steady in the lower 70s, with dewpoint temperatures in the mid to upper 60s.
1242 AM EST Thu Feb 15 2018 Warmer, more moist air will stream northward into the region through Thursday with chances for rain, drizzle and fog.
Records in south central and southeast Kansas are vulnerable being in the low 70s.
As of 21Z Wednesday afternoon a western mid-level trough axis was positioned along the west coast. Tonight: The CWA will remain in the warm sector ahead of the next cold front. That being said, RAP/HRRR/NAM soundings suggest a stout dry layer within the low levels, which should keep things dry. Thursday: The aforementioned surface cold front looks to traverse the CWA from northwest to southeast throughout the day. These gusty winds coupled with RH values in the lower 30s percent will yield high to perhaps very high fire danger Thursday afternoon for areas mainly along and southeast I-35/335.
