240 AM CST Sat Mar 3 2018 Dry and seasonal conditions continue across the mid state with upper level ridging building aloft. Sunny skies and highs from the mid 50s to mid 60s are in store for the weekend, along with lows around and just below freezing this morning and Sunday morning.
A passing cold front will bring chances for rain and snow Saturday night into Sunday.
1045 PM CST Fri Mar 2 2018 High pressure over the region today under an upper level ridge, will allow for mild temperatures and light winds through this afternoon and tonight. The south winds will allow temperatures to climb into the lower 60s.
forecast area remains under southwest flow aloft with low pressure systems to our west/northwest and off the east coast. 850mb temperatures warm 3F to 8F across the area supporting highs in the low to mid 70s.
324 AM CST Sat Mar 3 2018 Another nice day expected across the region today as high pressure continues to wedge in from the north. A trough moving into the west coast will cause pressures to begin falling in the lee of the Rockies today and especially tonight.
A large upper level low was moving onshore toward the area. The aforementioned upper low spinning into the Great Basin will move overhead Saturday night and into Sunday. The cold front associated with the low will fire off precipitation in the 6-12z timeframe for the western counties of the CWA. This quick shot of snow could change back to rain in the late morning and afternoon for the lower valleys as temperatures climb through the middle 40s.
Today a broad area of high pressure is building across the Upper Great Lakes. To the west, a low pressure system developing over eastern Colorado will result in southerly flow across the Great Plains and Mississippi River Valley late today into Sunday. A warm front will track northeast across the Upper Midwest late today into Saturday as the warmer air advects in from the south, resulting in increasing cloud cover and a chance for light precipitation on Saturday.
351 AM EST Sat Mar 3 2018 High pressure over central Canada will slow build eastward into the area this weekend.
1122 PM CST Fri Mar 2 2018 Besides a few high clouds, a ridge of high pressure was providing the area with mostly sunny skies while temperatures as of 1 pm were in the upper 30s to the upper 40s. Mid level ridge amplifies over the region through Saturday in warm air advection ahead of a deepening low moving out of the Rockies.
1153 PM EST Fri Mar 2 2018 Definitely not much to talk about tonight as high pressure settles directly overhead. Narrow ridge of high pressure extends from far northern Ontario, across western Superior, WI and IL. This ridge will slowly creep eastward into northern MI thru Saturday. Building 500mb ridging (ahead of troffing pushing into the Great Basin) will help support a deeply dry airmass. Max temps Saturday in the lower 30s to lower 40s. Rather benign weather continues into the second half of the weekend as ridging lingers over the Upper Great Lakes both at the surface and aloft.
The SPS mentioning the sub- freezing temperatures will be reissued.
High pressure will build eastward across the Great Lakes while ridging strongly southward to the Gulf Coast. Deep layer ridging will gradually build eastward toward our area as a trough axis moves farther offshore of the Atlantic coast. Light northerly to northeasterly flow will result in cooler temperatures throughout this period than previous weeks, as highs will only reach the upper 60s to lower 70s each day.
1208 AM EST Sat Mar 3 2018 Dry weather is expected through the weekend as a ridge of high pressure settles across the area.
906 PM PST Fri Mar 2 2018 A low pressure system will move slowly through California tonight and Saturday, bringing showers along with gusty winds in the mountains and deserts.
A strong Canadian high will ridge south across Fl while a deepening storm system pivots to the southeast and east well offshore the New England and mid Atlantic coast.
Widespread mid-clouds over southern WI are expected to gradually thin as upstream warm air advection weakens and shifts farther north as strengthening long wave ridging builds into the western Great Lakes. Onshore winds will keep temperatures a few degrees cooler by Lake Michigan, with slightly warmer readings than yesterday expected inland. The upper level ridge moves to near lake michigan, with a diffluent southwest upper jet approaching. The low levels are initially dry, so mainly VIRGA may be the result.
514 AM MDT Fri Aug 9 2019 Current upper level analysis has broad ridging across the south central CONUS with large trof across the West Coast and over the northeastern US. At the surface, trof of low pressure extends from eastern Montana south to eastern Wyoming.
An upper trough is moving out of Wyoming into western South Dakota at current, suppressing the upstream ridge. While upstream dewpoints are only in the low/mid 60s, PWATS in both the GFS/NAM increase to around 2 inches. Still looks like the west coast longwave trof/middle of the CONUS upper ridging pattern appears to only be interrupted during the middle of the weekend, when energy within the trof kicks out and moves out across the plains region.
439 AM CDT Fri Aug 9 2019 Early morning satellite imagery and radar show quiet weather across eastern Kansas and western Missouri as high pressure builds into the forecast area. An upper level trough will move inland along the West Coast Saturday.
High pressure still dominates Texas and will continue to do so for at least the next several days. Onshore flow is keeping the humidity and heat indices elevated, and the center of the ridge will be parked over Central TX in the short-term.
/issued 313 AM CDT Fri Aug 9 2019/ The Mid-South remains in northwest flow aloft this morning as an upper ridge remains located over the Southern Plains and a broad upper trof sits over the East Coast. The upper ridge will gradually begin building east during the latter part of the weekend. As it does, chances for convection will begin to diminish and temperatures will begin to creep back into the lower to mid 90s for highs.
1126 AM MDT Fri Aug 9 2019 Current upper level analysis has broad ridging across the south central CONUS with large trof across the West Coast and over the northeastern US. At the surface, trof of low pressure extends from eastern Montana south to eastern Wyoming.
Tomorrow, an upper level low is forecast to track across the central Canadian prairies with an attendant cold front moving into North Dakota by the afternoon hours.
Both ECMWF and GFS prog the upper level high pressure system directly over West Central Texas today.
Center of upper ridge remains across portions of Texas, with a broad upper trough situated over the eastern portions of the U. Highs this afternoon still on track to reach the upper 90s in most areas, with heat index values in the lower 100s. Mostly clear tonight with lows in the low to mid 70s.
By Saturday afternoon, the low moves into SW Oregon with a dry SSW flow spreading north into the Snake Plain and SE mountains through the day and strong dynamical support for enhanced thunderstorm activity overspreading WRN Idaho and perhaps the western portion of the CNTRL mountains.
1232 PM CDT Fri Aug 9 2019 Early morning satellite imagery and radar show quiet weather across eastern Kansas and western Missouri as high pressure builds into the forecast area. An upper level trough will move inland along the West Coast Saturday.
Building high pressure, decreasing winds, and mostly clear skies will support seasonable low temperatures in the middle-upper 50s.
/issued 332 AM CDT Fri Aug 9 2019/ Widespread convection over the northeast half of our forecast area is forecast to weaken later this morning as the moisture feed from the low-level jet diminishes. The upper-level ridge to our south/southwest will shift to a position over north Texas and Oklahoma this weekend. As the ridge recedes a bit early/mid week, rain chances will return, and temperatures will drop back below the seasonal average for a few days.
Elsewhere and especially along the Lake Superior shoreline and Keweenaw Peninsula, lows will be locally warmer. Saturday will be warmer as high pressure currently parked over southern Minnesota slowly starts to move eastward. As the high shifts east, the pressure gradient will also relax quite a bit and allow for winds to become lake-driven throughout the day.
Clouds and rain kept much of the area in the low to mid 80s today but this will be the last respite from the usual August heat and humidity. This will favor a setup like last night, with upper level waves interacting with the low level jet and resulting in more scattered storms tonight.
and Saturday Dry and quiet weather will continue across the western Great Lakes today and tonight as high pressure slides through the area. Daytime highs today will be a few degrees warmer, rising into the middle to upper 70s across north-central and central Wisconsin to around 80 across east-central Wisconsin.
112 PM EDT Fri Aug 9 2019 A cooler, less humid, and dry weather pattern will last through the weekend.
This front is expected to just make it through the area by Saturday morning before it begins retreating northward as a warm front. as the low level jet sets up. The persistent upper level ridge over the Southern Plains will begin to build into the region on Saturday. Just to the west of the upper level ridge is an upper level trough just off the Pacific Northwest coast. As the trough moves inland. it will begin to flatten the upper ridge driving the warmer air mass into the area.
500 mb heights don't change much and 850 mb temperatures look similar to today so it's not completely clear why numerical guidance is trending cooler. Will trim a degree from today's values but not convinced it will be much cooler as suggested by guidance. Latest guidance has temperatures a bit cooler for the start of the week compared to previous runs, but temperatures will still climb into the mid to upper 90s and heat indicies going into the triple digits. The ridge of high pressure remains overhead through the beginning of the workweek limiting POPs, although the typical diurnal shower or thunderstorm is possible in the afternoon hours. The chance of showers does increase beginning midweek as ridge weakens/slides to the west.
Northwest mid level flow that has been persistent over the Plains the last several days is forecast to gradually shift to the east as ridge axis slowly pushes toward the Missouri River Valley from the High Plains.
241 PM CDT Fri Aug 9 2019 18Z surface data has high pressure over the upper Midwest. Tonight quiet, dry and cool conditions will be seen as high pressure moves into the Great Lakes.
120 PM CDT Fri Aug 9 2019 Beautiful day in place today with high pressure sprawled out across the Upper Mississippi Valley. Under mostly sunny skies, temperatures as of 1 pm were in the 70s with pleasant dew points in the lower and middle 50s. High pressure will drift east across the area overnight as a dissipating complex of storms approaches areas west of the Mississippi River from the Northern Plains toward daybreak. Otherwise, a mostly cloudy/cooler day on tap with highs mainly in the 70s.
Drier conditions will be in place across the Cowboy State today, as the ridge axis rebuilds over the region. This will partly be due to an upper low that will slowly make its way onshore near CA/OR. Saturday through Friday A trough on the West Coast pushes further eastward Saturday. The flow around the trough will help pull in moisture, keeping the PW values higher, esp for this time of year.
Expanding mid-level ridge expected to lead to warmer conditions on Saturday, with floor of the Canyon perhaps reaching 105 degrees, leading to possible issuance of a Heat Advisory.
At the risk of sounding like a broken record, hot and dry conditions will persist with high temperatures from 100 - 107 across most of the area, as we roast under high pressure.
248 PM CDT Fri Aug 9 2019 Well above normal temperatures will continue into this weekend as a strong mid-summer ridge remains parked over the region with a 594-595 dam high located over central TX.

1132 AM CDT Fri Aug 9 2019 A weak cold front as of 0800 UTC is located near a KCOU>>K3LF line and progressing to the southeast. Near normal temperatures are also forecast to continue with lows tonight in the low to mid 60s and highs to start off the weekend once again in the mid to upper 80s. Gosselin The upper RIDGE will remain nearly stationary over the southern Plains through the period. What changes over time is the ability of this RIDGE to intrude into our region. When the RIDGE builds in over our region and corresponds to a southerly surface flow, high levels of heat can be expected.
The problem with the forecast is locating the low level focus for best rain chances.
