1113 AM CST Fri Nov 8 2019 High pressure will remain over the region through Saturday. This high will keep conditions dry while warm air advection into the region will allow temperatures to rise well above normal for this time of year. Highs on Saturday will be nearly 10 degrees warmer with afternoon temperatures in the mid 60s to mid 70s. These strong winds combined with warmer temperatures and dry conditions, may lead to fire concerns.
104 PM EST Fri Nov 8 2019 Light and scattered snow showers can be expected Today in the cold flow off the lakes, mainly north of Interstate 80 and in the ridges. NW flow on the backside of an exiting trough will keep cool air in place for the region while creating occasional lake enhanced fetches of snow showers for areas mainly north of I-80 and along the eastern ridges.
1127 AM CST Fri Nov 8 2019 A chilly/mostly clear overnight across the area with high pressure overhead. Brrr, is this early November or mid January? For today, the high drifts southeast while low pressure moves across southern Canada and the Dakotas. Plan on highs in the middle 20s across central WI, to the lower/middle 30s along and west of the Mississippi River. Overnight lows look to be in the low/mid 20s. A cold front pushes through Saturday night continuing cloud cover and possibly squeezing out a few snow showers.
Low-level warm air advection has brought increasing clouds to the area overnight, and will persist today ahead of a weak northern stream trough set to sag southeast across the area tonight.
Temperatures are running a touch warmer this morning, so hard to tweak hourly temperatures up a degree or two. Northerly winds will be on the decline past noon as high pressure expands into northeastern Texas.
As is often the case in this pattern, confidence is not particularly high in the exact timing of the low clouds mixing out. This cold air advection is directly related to northeast winds of up to 25 knots in the low levels. This westerly flow also continues to bring Pacific based moisture into the area as indicated by high RH values in excess of 70% throughout the low and mid-levels of the atmosphere. This warm and moist airmass is being isentropically lifted over the cooler air near the surface resulting in a broad area of cloud cover this morning.
Saturday will be mostly cloudy and a bit warmer than today. Temperatures Saturday should climb to the freezing mark in most places.
Mostly high clouds should linger through the overnight hours before clearing from northeast to southwest as high pressure builds in.
Some low level moisture return evident on the west side of the high with extensive cloud cover west of I-35 and over parts of southeast OK.

146 PM EST Fri Nov 8 2019 High pressure will bring fair weather but cold temperatures to the Appalachians and central mid Atlantic region into the weekend.
Some light precipitation, mix of freezing drizzle/sleet/snow is possible across far northwest North Dakota after midnight. A strong cold front passes through Saturday afternoon with a tight surface pressure gradient bringing breezy winds and strong cold air advection. Ensemble guidance and forecast sounding suggest a narrow corridor of freezing drizzle or mix of sleet/freezing drizzle/snow stretching from northwest through central North Dakota Saturday morning along and ahead of the front with dry mid-levels and warmer air aloft. As drier air moves in behind the front Saturday evening we could once again see a loss of ice aloft and a transition back to freezing drizzle over northern and central North Dakota.
1135 AM MST Fri Nov 8 2019 Dry weather and slightly above normal temperatures will continue into the weekend under the influence of high pressure.
243 PM CST Fri Nov 8 2019 High pressure was centered over central Illinois as of 2 PM. Temperatures at 2 PM were generally in the lower to mid 30s with gusty southerly winds of 10 to 20 MPH.
The timing of the approaching cold front from the north should help us reach near our maximum potential for highs, barring any unforeseen thick cirrus. Overall synoptic pattern still looks like it is on track as the amplification of the west coast/eastern Pacific ridge allows very cold air to settle south into the eastern 2/3 to 3/4 of the United States.
Lows tonight will drop into the mid 20s, with highs on Saturday in the low to mid 40s.
319 PM EST Fri Nov 8 2019 Updated at 315 PM EST Fri Nov 8 2019 Strong Canadian high pressure settles over the region tonight, before pushing off to the mid Atlantic Coast tomorrow.

Updated at 315 PM EST Fri Nov 8 2019 Strong Canadian high pressure settles over the region tonight, before pushing off to the mid Atlantic Coast tomorrow. Given light and variable winds, low dew points in the teens, and mostly clear skies overnight temps should settle into the low 20s in most spots.
A very quiet weather pattern will continue across the Great Basin as high pressure remains in control across the western U.
Regional radars show lake-enhanced shower coverage gradually diminishing as the wind field continues to back in response to high pressure building in the S/SW. Along with the showers, the remaining stratocumulus deck will also erode over the next few hours as dry air advects into the low/mid- levels from the SW. Upper cloud cover will move back into the area late tonight in response to an approaching upper trough axis. cold air in place, little wind, and an initially clear sky, the temperature will quickly drop into the low 20s area- wide.

600 PM CST Fri Nov 8 2019 Some high clouds passing through today with a weak trough moving over the region, with blustery winds out of the south to continue through the daylight before falling back overnight.
With air temperatures 30 to 40 degrees colder than the water temperatures, some patchy freezing fog may form overnight through around sunrise.
This southerly wind shift along with dewpoints remaining in the 40s will keep temperatures from bottoming out too much overnight w/forecasted lows above freezing. A quasi-zonal 500 mb pattern will set up over the region for the next couple of days and calmer, warmer, and drier conditions will transpire.
A light north to northeast wind flow expected tonight through Saturday as mid to upper level high ridge settles across the local area.
Despite a very subtle high level wave increasing the cirrus overhead, temperatures have soared into the 50s in snow free areas, with cooler readings approaching 40 degrees in areas with lingering snow depth. Tonight: A weak trough will pass through the area overnight, but mixing will persist. Saturday: Depending one the presence of cloud cover early Saturday, the favored areas for a substancial warmup will be near the MO River, with this warmer air spreading further east of the James River valley by late afternoon. Have trended towards the higher side of guidance for 2/3 of the CWA, and limited the warmup over the lingering snow slightly.

Slight upper ridging will move in across the region tomorrow and, with southwesterly surface flow and clear skies, will allow temps to warm into the 60s/70s tomorrow and Sunday.
VFR expected through the TAF period as high pressure moves across the southern Appalachians region.
/issued 820 PM EST Fri Nov 8 2019/ As advertised, cooler and drier air has begun filtering into the region this evening in the wake of a cold front currently located over the southern peninsula. Temps have fallen into the low/mid 60s thus far across the Nature Coast while temps down south and closer to the front are still hovering in the upper 70s.
1118 PM CST Fri Nov 8 2019 Some high clouds passing through today with a weak trough moving over the region, with blustery winds out of the south to continue through the daylight before falling back overnight. After a brief quiet period behind the first cold front from Saturday, a reinforcing surge of arctic air will begin pushing into the region on Sunday afternoon.
237 AM EST Sat Nov 9 2019 High pressure overhead today will shift east tonight, and remain close through Sunday.
300 AM EST Sat Nov 9 2019 Freezing temperatures are possible over most inland areas this morning as cold high pressure builds in from the west thru Sat night.
Current temperatures are generally in the lower to mid 20s. 850 mb waa will pick up as well so under plentiful sunshine, look for the mercury to reach the lower to mid 50s. The return flow will pick up a touch in magnitude on Sunday so look for highs into the lower to mid 60s. Freezing levels suitable for snowfall does appear to intersect the moisture fields with adequate depth toward the back end of the precip field.
344 AM EST Sat Nov 9 2019 A cooler and drier air mass has moved into the area in the wake of a cold front located across the southern part of the peninsula. After a cooler start to Sunday, highs will go back up into the mid 70s to lower 80s although it will still feel pleasant outside.
1017 PM MST Fri Nov 8 2019 Latest analysis shows an upper ridge over the western CONUS and a trough over the east, placing the forecast area under northwesterly flow aloft. On Saturday, the thermal ridge will peak over the region. Westerly low level flow and relatively deep mixing with lead to breezy/windy areas with high temperatures at many locations around 10 degrees warmer than the average for this time of year. Initially, the precipitation may start as a brief period of light freezing drizzle as the cold air flowing in at the surface undercuts a warm advection layer aloft.
1003 PM MST Fri Nov 8 2019 The short term forecast will bring a well-above normal temperature regime, with lows tonight barely making freezing, rebounding to the mid 50s to near 60 Saturday. Early Sunday morning will see a cold front begin moving into the northern portions of the state bringing cold temperatures and areas of light snow.
154 AM MST Sat Nov 9 2019 Overview: NW flow aloft will prevail through tonight -- on the eastern periphery of an upper level ridge over the western CONUS. Tonight: Aside from a potential for transient cirrus, expect clear skies, light winds, and lows in the lower-mid 30s. Sat-Sat night: A warming trend will persist in association with southwesterly low-level flow on the eastern periphery of a developing lee trough, amidst NW-WNW flow aloft.
1115 PM CST Fri Nov 8 2019 High pressure will bring VFR conditions to area TAF sites tonight and Saturday. The high will also bring a weak pressure gradient and lighter winds to the region. A light north to northeast wind flow expected tonight through Saturday as mid to upper level high ridge settles across the local area. The southerly flow will also allow for warmer temperatures, likely reaching the 70s areawide Sunday afternoon.
High pressure remains in control of area weather this evening, though some flattening of the ridge is anticipated on Saturday. This ridge flattening is expected to have little consequence, other than the potential for a few more clouds over the area. A disturbance looks to impact the area on Sunday, with an opportunity for some showers over the West Central Mountains in Idaho, with a ridge quickly returning after its passage. A weak cold front Sunday morning will bring clouds and a slight chance of MVFR showers to the Central Idaho Mountains. High pressure over the area will combine with light boundary level wind and low mixing heights to continue stagnant conditions.
Stuck on cooler MAV/MET solution for overnight lows tonight/Saturday morning, which supported converting the previous Freeze Watch tier in portions of central GA to join the rest of the northern majority in the Freeze Warning. Lows Saturday night into Sunday morning may actually be lowest and more near the freezing mark for central and eastern GA given this setup for maximized radiational cooling.
High pressure will bring VFR conditions to area TAF sites on Saturday. The high will also bring a weak pressure gradient and lighter winds to the region. A light north to northeast wind flow expected tonight through Saturday as mid to upper level high ridge settles across the local area. The southerly flow will also allow for warmer temperatures, likely reaching the 70s areawide Sunday afternoon.
As the ridge exits the area, winds will become south to southwest and gust into the teens by afternoon, helping to return warmer air into the area.
1055 PM EST Fri Nov 8 2019 Water vapor imagery highlights a digging short wave trough over the northern Gulf Coast. A cold front over south-central Florida will be driven south tonight and Saturday by the Gulf Coast clipper. The first cold front is upon us, find those jackets. From synopsis, a cold front now over south- central Florida will move through the coastal waters of the Florida Keys Saturday, reaching Cuba by late Saturday. Strong high pressure now over the Southeastern United States, will settle across Florida through the weekend, resulting in fresh to strong breezes across all coastal waters.
Focus will be the warmer temps with southerly winds thru Sunday and mostly clear sky. With a slower arrival of the cold front on Sun, have trended warmer across the area, but moreso across the southern portions where less clouds and more insolation is anticipated. Upper trof will dig into the region Sun night into Mon. The trof along with frontogenesis will help support light precip across northern portions of the CWA. The timing of the cold front is a bit slower compared to yesterday. Temps may moderate slightly for Thurs, but a reinforcing cold front is expected to move thru the area keeping Fri cooler.
This will be the last mild day for a while as a strong back door cold front works through the area tonight. With that said, adequate saturation appears to be a potential issue at times within the dendritic layer, and there is a potential for freezing drizzle.
Temps on Sunday will be nearly steady as cold air continues push south with 1040 arctic high pressure building into the high plains. 850 temps popping above 0C by Fri should translate to sfc readings above freezing to near 40.
245 AM MST Sat Nov 9 2019 A ridge of high pressure will continue to support dry conditions and above normal temperatures today. A trough will graze the region Sunday night, bringing cooler temperatures to begin the work week.
947 AM EST Sat Nov 9 2019 High pressure overhead today will shift east tonight, and remain close through Sunday.
The upper level ridge will flatten a bit today as a deep trough digs into the Central US.
600 AM EST Sat Nov 9 2019 High pressure overhead today will shift east tonight, and remain close through Sunday.
Tight low level baroclinic zone across central ND will lead to a quick transition of rain to snow with a narrow ribbon of freezing rain or sleet possible. Temps on Sunday will be nearly steady as cold air continues push south with 1040 arctic high pressure building into the high plains. 850 temps popping above 0C by Fri should translate to sfc readings above freezing to near 40.
324 AM CST Sat Nov 9 2019 It will be warm today with light southwest wind and even warmer Sunday with afternoon temperatures 5 to 10 degrees above normal. Lower and mid-level moisture will increase on south and southwest fetch from an upper level low near Baja California. Later Sunday, a broad but strong trough in the westerlies will move into the central plains bringing a strong front south.
