345 AM CDT Fri Oct 2 2020 Early this morning, an upper longwave TROF prevailed over eastern North America with a RIDGE over western North America. The axis of the TROF was just east of our region. A pair of upper level disturbances of note were located over western Canada, riding over the RIDGE lodged there. At the surface, a 1026mb ridge of high pressure dominated the Plains. The positions of the upper longwave TROF and RIDGE will change very little through Saturday. There is good operational model consensus on the highest PoPs for central and northeast MO during Saturday morning and is further supported by the HREF, with a lessening in coverage then occurring during Saturday afternoon.
401 AM EDT Fri Oct 2 2020 Post frontal cold air advection through the night will set the stage for an even cooler day today as high temperatures this afternoon struggle to climb into the low to mid 50s. The inland areas will see surface moisture driven south as a weak high pressure begins to settle into the area by tonight. These cloud trends will ultimately govern the frost potential tonight into tomorrow morning as overnight lows are expected to dip to near freezing and winds become light to calm.
313 AM CDT Fri Oct 2 2020 Mid level clouds were slowly moving southeastward early this morning as a cold front was sinking southward across the area. Dewpoints were in the upper 30s behind the cold front with lower to mid 40s along and ahead of the front. High pressure will quickly move across the area today with northwesterly winds becoming light and variable this afternoon with high pressure overhead. Light cold advection and cloud cover will lead to a cool day across eastern Iowa, northwest Illinois, and far northeast Missouri with highs in the lower to mid 50s. Due to the cloud cover, temperatures are forecast to be 1 to 2 degrees warmer than tonight with dewpoints across the area in the mid 30s. This may lead to patchy frost along the Highway 20 corridor on Saturday morning.
Current temps are in the lower to mid 40s, with a couple of locations dipping just below 40. Overall, temperatures today are forecast to be a bit cooler than yesterday, with highs topping out in the mid 60s, about 10 degrees below normal. As we move into Friday night, may see some lingering cloud coverage, with low temperatures expected to once again fall into the low to mid 40s. Saturday will be dry and pleasant as high pressure exits the upper Ohio Valley.
VFR conditions will prevail through this TAF cycle at all sties as high pressure continues to persist over the region. VFR conditions will prevail through the TAF cycle at all sites as high pressure remains in control over the region. Light and variable winds will prevail tonight, becoming slightly stronger out of the northeast in the morning as a weak surge of reinforcing high pressure builds across the region. This is in response to the long wave trough over the eastern U.
Sunny and warm again today and Saturday as high pressure over the southwestern U. and a large upper trough over the eastern U.
Morning lows will be chilly in the upper to mid 30s with highs reaching into the lower 60s. Northern Missouri is expected to stay cooler in the upper 50s. As the trough moves out of the area by Saturday evening, so too will rain chances taper off by the afternoon. Cloud coverage Saturday will keep temps cooler with highs in the upper 50s to lower 60s. Areas south of I-70 may see less rainfall and less cloud coverage, leading to a warmer high temp in the upper 60s.
256 AM EDT Fri Oct 2 2020 An upper level trough will persist over the Great Lakes through this weekend, providing below normal temperatures.
211 AM MDT Fri Oct 2 2020 08z surface analysis had high moving into to the Midwest with a warm front across eastern MT into eastern WY. Gusty northerly winds expected behind the cold front per 2-3mb/3hr pressure rises combined with 25-30kt boundary layer flow. Saturday, cooler day expected with readings near guidance.
253 AM MDT Fri Oct 2 2020 Highly amplified pattern continues across the US, with ridging along the west coast, and deep trough from the Great Lakes to Florida. Saturday will see the after-effects of the Friday front, with temperatures about 5 degrees cooler during the day. High pressure settling in will bring light and variable winds during the afternoon.
Cooler air and slightly breezy conditions have made their way east of the central mountain chain today following a backdoor cold front. Another backdoor cold front arrives Saturday night, but with little precipitation to speak of. A strong ridge of high pressure will remain entrenched over the western US. Another back door cold front will move into northeast NM Friday night with a wind shift out of the north and northeast.
Late tonight/early Friday, a dry cold front will move through, bringing cooler temperatures for the area tomorrow. A dry cold front late tonight/early Friday morning, leading to cooler temperatures again and persisting dry conditions. Overnight, temperatures will dip into the low 50s across inland SE GA, low- mid 60s in NE FL. A warm front will lift into central FL, bringing a return of chances for showers, mostly from St. Daytime temperatures will remain cool, in the 70s, then overnight lows will warm up with the return of the warm front, ranging from the upper 50s in SE GA, mid-upper 60s from Jacksonville southwestward to Gainesville.
212 AM MDT Fri Oct 2 2020 Montana will be in a NW flow aloft today and Saturday with a ridge to the west and an upper trough to the east. The pattern will remain highly amplified with the ridge over the western portions of most of the continent, and the trough over the eastern portions, anchored in the Hudson Bay. Look for temperatures that will be around 10 degrees warmer than yesterday. Winds will diminish this evening as high pressure moves into the region. Look for light winds on Saturday and mostly sunny skies along with somewhat cooler temperatures.
It could be challenging to see any frost develop with what appears to be marginally increasing high level cloud cover over the western half of the state, and temperatures still hovering in the low 40s in many locations. A surface cold frontal boundary will be driven across the area after midnight - and with mixing accounted for in the boundary layer, a slightly more mild and breezy overnight is likely with north winds area wide.
1007 PM CDT Thu Oct 1 2020 Another cool, dry, and overall pleasant night is expected as a reinforcing cold front continues to slide southward into the Gulf. /issued 354 PM CDT Thu Oct 1 2020/ A plume of high clouds riding around the western side of an upper trof over much of the eastern U. Temperatures have warmed into the low to mid 80s this afternoon, but with dewpoints still in the upper 40s to lower 50s conditions continue to be quite pleasant. The aforementioned trof will push a dry front through the region later this evening.
Upper level trof diving over the Great Lakes Region is wide enough that a weak backdoor cold front is currently over the Panhandles. Temperatures much cooler than yesterday, yet just a couple degrees below normal. Winds will shift out of the south again this evening and warmer air will return tomorrow with highs in the upper 70s to lower 80s. A weak disturbance riding down the back side of the trof will latch onto some of that cooler air and briefly pull it over the Panhandles again on Saturday, with highs again in the lower to mid 70s, which is right around normal for this time of year.
Strong high pressure will build in from the north and west for the remainder of the short term period.
/Today through Saturday/ Broad-scale upper trof axis remains in place across the ern CONUS.
1036 PM MDT Thu Oct 1 2020 Upper ridging is persisting across the western CONUS, with northwest flow aloft across the Great Plains. This wave will bring a cold front to the area, with gusty NW winds behind it. Temperatures will be near to slightly below normal through Saturday, then a low amplitude thermal ridge will cross the region, bringing above average temperatures through the first half of the week.
357 AM EDT Fri Oct 2 2020 High pressure over the Mid Mississippi Valley will move east today and be centered over the Mid Atlantic region tonight.
The period will start out with an upper trough over the central- eastern half of the CONUS/Canada with a ridge over western areas.
Satellite, water vapor, and RAP analysis shows a deep trough over the eastern CONUS now fully entrenched with cold, dry air advection across the region. Highs will only reach the low/mid 60's in this cool pattern, 10-15 degrees below normal. High pressure across the area will result in a clear sky and light northerly winds through the period with VFR conditions at all sites.

Next cold front will begin to push south late in the period, leading to northwesterly winds beginning at DHT and GUY before 12z. WV satellite continues to show pattern dominated by upper ridging over the western CONUS and cyclonic flow across the eastern two thirds of the CONUS with a belt of enhanced flow between these features over WA extending southeastward to E CO. At the surface, large scale high pressure is in place over the northern and central Plains with generally some form of southerly winds occurring across the Panhandles. Saturday, the latest Plains cold front looks to push south, with GFS/NAM/CMC/EC depicting this feature clearing the Panhandles during the 12z to 18z time frame.
629 AM CDT Fri Oct 2 2020 High pressure will remain in control with VFR conditions prevailing throughout the forecast period. Sunny and warm again today and Saturday as high pressure over the southwestern U. and a large upper trough over the eastern U.
550 AM CDT Fri Oct 2 2020 Early this morning, an upper longwave TROF prevailed over eastern North America with a RIDGE over western North America. The axis of the TROF was just east of our region. A pair of upper level disturbances of note were located over western Canada, riding over the RIDGE lodged there. At the surface, a 1026mb ridge of high pressure dominated the Plains. The positions of the upper longwave TROF and RIDGE will change very little through Saturday. There is good operational model consensus on the highest PoPs for central and northeast MO during Saturday morning and is further supported by the HREF, with a lessening in coverage then occurring during Saturday afternoon.
VFR conditions will prevail with high pressure suppressing cloud cover and rain chances. The region is dominated by high pressure in the mid- levels, which stretches across Deep South Texas. This will allow winds to remain out of the northeast and finally shift back to the southeast on Saturday as the high quickly moves across the Great Lakes region. With onshore flow returning on Saturday, humidity will creep upward during the day with highs reaching the lower 90s.
Mid level clouds were slowly moving southeastward early this morning as a cold front was sinking southward across the area. Dewpoints were in the upper 30s behind the cold front with lower to mid 40s along and ahead of the front. High pressure will quickly move across the area today with northwesterly winds becoming light and variable this afternoon with high pressure overhead. Light cold advection and cloud cover will lead to a cool day across eastern Iowa, northwest Illinois, and far northeast Missouri with highs in the lower to mid 50s. Due to the cloud cover, temperatures are forecast to be 1 to 2 degrees warmer than tonight with dewpoints across the area in the mid 30s. This may lead to patchy frost along the Highway 20 corridor on Saturday morning.
The air mass remains dry and warm with above normal temperatures seen area wide due to an amplified ridge of high pressure remaining out west. Overnight temperatures still remain on the cooler end of guidance due to efficient radiational cooling under clear skies. Skies are expected to clear behind this disturbance tonight, so anticipate more of the same with below freezing temperatures tonight in the higher northwest Colorado and Gunnison valleys and slightly below normal temperatures elsewhere. Daytime temperatures on Saturday will be a bit cooler in the wake of today's passing disturbance but still remain mild with temperatures 5 degrees above normal. The persistent ridge of high pressure holds strong across the west, bringing continued dry conditions and above normal warmth through the coming week.
736 AM EDT Fri Oct 2 2020 High pressure will build in behind a cold front this morning and persist through Saturday.
Sfc analysis showing a strong ridging centered across NE OK/NW AR and SW MO with the ridge axis oriented south and west across N TX into Central TX attm. This leaves us with northeasterly flow at the surface but that ridge axis will quickly shift eastward and should be over our entire region late this afternoon into the early evening hours. Temperature advection in the lower levels is relatively neutral even given the northeast winds at the surface and given the dry conditions, temperatures are warming up quickly. /issued 623 AM CDT Fri Oct 2 2020/ High pressure at the sfc and nwly flow aloft will result in prevailing VFR conditions for the 12Z TAF pd.

This will result in slightly warmer temperatures, with overnight lows in the mid and upper 50s.
623 AM CDT Fri Oct 2 2020 High pressure at the sfc and nwly flow aloft will result in prevailing VFR conditions for the 12Z TAF pd. /Today through Saturday/ Broad-scale upper trof axis remains in place across the ern CONUS.
Chilly morning across Middle Tennessee thanks to the cold front that moved through yesterday, with current temps mostly in the 40s but a few spots in the Upper Cumberland have dropped into the upper 30s. Saturday looks to be a near carbon copy of today, but just a bit cooler in the morning with lows in the upper 30s on the Plateau and low to mid 40s elsewhere. Patchy fog is more likely Saturday morning throughout the area, but once again dewpoints look to be well above freezing so frost should not be an issue. Highs will be a bit warmer on Saturday versus today, but still very comfortable in the mid 60s to low 70s.
959 AM EDT Fri Oct 2 2020 An upper level trough will persist over the Great Lakes through this weekend, providing below normal temperatures.

On Saturday as this broad trough shifts east marginal forcing and weak instability mostly east of Interstate 29 should allow for a few showers again, but not much rainfall expected.
High pressure will continue to persist across South Texas through Saturday. High temperatures will remain near normal while the low overnight temperatures will be slightly below normal. Weak northeast to east winds are expected today and tonight before becoming more southeasterly and picking up to moderate levels Saturday as the high pressure shifts slightly east.
Northwesterly flow aloft continues across the nation's mid section with amplified ridging over the western CONUS and troughing across the eastern third of the nation. Weak southerly return flow increases later today which should allow afternoon high temps to reach the lower to mid 60s. Point forecast soundings do indicate some moisture return in the lower levels, but feel this may be slightly overdone by models.
305 AM PDT Fri Oct 2 2020 High pressure will remain over the region through the first week of October, bringing warm afternoons, dry conditions, light winds, and chilly mornings.
735 AM EDT Fri Oct 2 2020 Composite trough axis and coldest midlevel air will pivot through Southeast Michigan between 12-18Z.
