659 AM CDT Fri Nov 1 2019 A cold front was moving across Minnesota early this morning. Ahead of this front, temperatures rose a few degrees from last evening, with several areas above freezing across southern Minnesota as of 3 am. The low level moisture has been lagging behind this front and once the low level moisture does increases this morning across eastern Minnesota, stronger forcing will weaken or end. All of these waves appear rather weak and therefore confidence in precip coverage is very low - hence the low PoP continues.
Issued by National Weather Service Pueblo CO 527 AM MDT Fri Nov 1 2019 Satellite pictures are showing some mid and upper level cloudiness moving across the CWA this morning associated with a weak upper trough. Downward motion behind the upper trough will be in place today and tonight for the CWA.
Today and Saturday: Models continue to keep the ridge of high pressure off the coast and keep the Inland Northwest cool and dry for the period.
Winds will begin to shift to the north late this evening/tonight as a high pressure ridge builds into the area. High pressure will drift east today returning onshore flow by midday today. As the reinforcing ridge moves over the area Saturday, winds will again shift to the north. Temperatures will again warm into the mid 60s to the low 70s across the region.
639 AM CDT Fri Nov 1 2019 GOES water vapor imagery early this morning showing a mid-level trough digging southeast through the Dakotas. This was pushing a surface cold front through central MN/western IA. The cold front will swing east through the area today with increasing low level lapse rates in daytime heating. Mid-level trough/cyclonic flow moving through tonight into Saturday morning expected to shake out a few snow showers. The trough departs east Saturday afternoon with a ridge of high pressure building in from the Plains. Ridge of high pressure moves overhead Saturday night but cloud cover ahead of next system dropping into the Northern Plains will send more clouds into the area.
Currently, a strong upper low continues to lift into the New England states with broad cyclonic flow pattern stretched across the rest of the CONUS.
High pressure centered south of the PAH forecast area will drift northeast today. Models bring a weak cold front across the middle Mississippi and lower Ohio valleys late tonight into Saturday morning.
Some morning fog has developed south of the lake Wales Ridge and West of Lake Okeechobee and some of that has worked its way into PGD.
6Z surface data has a cold front running from northern Minnesota into southern South Dakota. At this point, these should be very light qpf systems but as we fluctuate above and below freezing, there could be some hazards for travel if light freezing rain or snow results.
949 AM EDT Fri Nov 1 2019 Finally some cooler and drier conditions across most of the area today thanks to a cold front which currently looks to be right around Ft. Will leave in a slight shower chance in as far north as extreme southern Brevard, but the highest shower chances (30-40%) will fall across southern St.
/issued 359 AM CDT Fri Nov 1 2019/ As of this writing, the surface freezing line extends from west to east across central Louisiana making the freeze warning issued yesterday afternoon look like a good call. On the other side of the spectrum, some areas along the I-10 corridor to the coast are still observing winds between 5 and 10 MPH which is providing enough mixing to keep temperatures in the lower 40s. High pressure nearly overhead will keep winds very light out of the northeast while extremely dry air aloft will keep skies clear. This will likely keep overnight lows tonight a few degrees warmer although some patchy frost will still be possible across parts of central Louisiana and points north.
409 AM CDT Fri Nov 1 2019 A cold front was moving across Minnesota early this morning. Ahead of this front, temperatures rose a few degrees from last evening, with several areas above freezing across southern Minnesota as of 3 am. The low level moisture has been lagging behind this front and once the low level moisture does increases this morning across eastern Minnesota, stronger forcing will weaken or end. All of these waves appear rather weak and therefore confidence in precip coverage is very low - hence the low PoP continues.
Otherwise, expected breezy wind speeds behind a cold front today. Much of the CONUS is under large scale troughing in the upper levels. An upper level low is also noted over the Pacific just southwest of California. At the surface is where we will find our most noteworthy item for the short term, and that is the cold front expected to blast through later today.
High pressure centered over or just off the northern California coast will keep tranquil conditions going for northeast California, the Sierra, and western Nevada through the weekend. With no cooler air reinforcements, temperatures will continue to slowly modify over the next few days.
806 AM EDT Fri Nov 1 2019 Wind gusts should gradually decrease throughout the day as a low pressure system moves northeast. Quieter weather will prevail this afternoon and tonight as high pressure builds over the Ohio River Valley. With a strong low pressure system jetting to the northeast and high pressure building over the Ohio River Valley, wind gusts have improved a great deal. Elevations above around 2500 feet may still see occasional gusts upwards of 50 mph, so have left the advisory in place until 10AM for the highest elevations. A gradual clearing trend from the southwest is expected by early afternoon under building high pressure. Seasonably cool conditions are expected to be reinforced on Saturday with the encroachment of another cold front.
High pressure and dry offshore winds will maintain mostly clear skies with cool mornings through Saturday.
The winds will shift throughout the day today as a cold front moves into the area.
418 AM MDT Fri Nov 1 2019 The main weather contributor for the short term forecast (6 AM Friday through 6AM Saturday) will be a cold front passage over the eastern plains. Therefore, the lighter winds and colder temperatures will be over the adjacent plains and the windier conditions and slightly warmer temperatures will be over the far eastern plains. Upper level pattern remains fairly stable the next several days, with persistent ridge over the ern Pacific/West Coast. Some model differences appear Sun night into Mon, as 00z Euro drives a cold front south through the area, while 00z GFS is less amplified and keeps any cool air to the ne.
1036 AM EDT Fri Nov 1 2019 High pressure will build across the region through Saturday.
720 AM EDT Fri Nov 1 2019 High pressure will build across the state during the short term while a broad trough persists aloft. The main concern with this forecast cycle is the expectation of another night of freezing temperatures for a portion of north GA. morning lows for Saturday look borderline freezing for most of the area north of Atlanta to Athens.
648 AM CDT Fri Nov 1 2019 Today-tonight: Cold front should sweep across most of the forecast area during the day with little fanfare.
640 AM CDT Fri Nov 1 2019 Warmer and continued sunny today with highs in the 50s. A cold front moves through tonight, but will not be accompanied by precipitation. This will lead to a cooler day Sat with highs in the mid 40s to around 50 and breezy northwest winds. However, there is a chance for IFR, or potentially lower, ceilings late tonight into early Saturday morning behind a cold front.
255 PM MDT Fri Nov 1 2019 Stratiform cloud cover has developed along the southern Foothills and western portions of the Palmer Divide due to moisture evaporating off the snowfields on the plains being pushed against the terrain by a low-level anticyclone that has developed today. Temperatures aloft will be warming on Saturday, leading to a warmer day. Skies should be mostly sunny but temperatures will still be slightly cooler than normal due to the snow cover which will be decreasing through the day.
Anchored western NOAM ridge with associated mean central NOAM troughing will continue in the period, supporting continued local active NW flow.
228 PM CDT Fri Nov 1 2019 Current long wave setup over the US shows a broad trough axis over the eastern 2/3rd's with accompanying closed low over Quebec, followed by ridging along the west coast. Weak low over NM will push east, dragging a cold front through our CWA by later this afternoon and evening, but not before our temperatures rebound into the 60's and 70's areawide thanks to weak southerly flow and full sunshine. Attendant height falls on the base of the trough with northerly flow into Saturday will allow for cool start to the weekend with low temps near and north of I-20 dropping back below freezing.
Temperatures Saturday will be near guidance with breezy spots over the higher Black Hills and open plains.
302 PM CDT Fri Nov 1 2019 A dry sfc cold front extends from IA into eastern KS.
/Issued 720 AM EDT Fri Nov 1 2019/ High pressure will build across the state during the short term while a broad trough persists aloft. The main concern with this forecast cycle is the expectation of another night of freezing temperatures for a portion of north GA. morning lows for Saturday look borderline freezing for most of the area north of Atlanta to Athens.
This front will keep overnight lows below freezing (low 20s to low 30s) for most of the FA. Highs tomorrow will also be cooler by more than 10-15 degrees as northerly as surface winds will be slow to return to a south to southwesterly direction.
Quick update this morning to get rid of freeze warning/freezing fog advisory from products. High pressure has settled over Middle Tennessee and will remain the dominant weather feature for the foreseeable future.
357 PM CDT Fri Nov 1 2019 A weak cold front will move across the area tonight, which will result in slightly cooler temperatures Saturday than those seen today.
Temperatures are running about 15 degrees below normal for this time of year with readings in the lower 50s areawide. Latest surface analysis places a 1028mb high over the Lower Mississippi Valley, with a mature low pressure system over Ontario, Canada. With high pressure nearly centered over the Mid-South, it will be another great night for efficient radiational cooling across the area. Even though the majority of the area saw subfreezing temperatures last night, a few counties over northeast Mississippi will carry a freeze warning tonight that may have not have fallen below freezing last night. The rest of the area will see plenty of frost with temperatures at or near freezing. High temperatures will be nearly identical today, but will feel cooler due to 10-12 mph northwest winds.
301 PM EDT Fri Nov 1 2019 A dry dome of high pressure will provide us with a clear and chilly night tonight with light winds and low temperatures mostly in the 25-30 degree range. On Saturday a weak cold front will push through the region from west to east.
VFR conditions are expected through the forecast period, with south winds eventually becoming northwest as a cold front moves across the area tonight.
307 PM CDT Fri Nov 1 2019 After a brief warmup today for most of the area (although still below average), our next cold front is already making progress through northwestern Oklahoma and will bring a renewed push of colder air.
These southeast winds and moisture will keep temperatures above freezing overnight tonight. Early Saturday morning, a weak and dry cold front will pass through the area. Saturday night lows will be chilly, but like friday, should stay above freezing.
The upper trough swings east of the region tonight with persistent northwest flow flattening out across the region somewhat as additional weak waves move through the upper flow and form a broad trough over the bulk of the U. An area of high pressure at the surface moves across the high plains tonight with a trough deepening in the lee of the Rockies by late Saturday in response to the flattening upper flow.
Quick update this morning to get rid of freeze warning/freezing fog advisory from products.
1120 AM MDT Fri Nov 1 2019 The main weather contributor for the short term forecast (6 AM Friday through 6AM Saturday) will be a cold front passage over the eastern plains. Therefore, the lighter winds and colder temperatures will be over the adjacent plains and the windier conditions and slightly warmer temperatures will be over the far eastern plains. Upper level pattern remains fairly stable the next several days, with persistent ridge over the ern Pacific/West Coast. Some model differences appear Sun night into Mon, as 00z Euro drives a cold front south through the area, while 00z GFS is less amplified and keeps any cool air to the ne.
Was initially thinking it would be all snow, but it got warmer today than expected and models are trending milder in the lowest 2 kft. Medium Ridge axis shifts across the area leading to a quiet night.
256 PM CDT Fri Nov 1 2019 Upper level trough over the north central U. and associated weak cold front at the surface were producing an area of light rain across central Iowa reaching into northeast Iowa early this afternoon. A weak warm front reaching out ahead across eastern Iowa, and west to southwest winds, had warmed temperatures into the mid 30s to mid 40s across the local forecast area. There may then be a secondary area of lift in the northwest flow behind the passing trough that may trigger a few flurries or very light snow.
143 PM EDT Fri Nov 1 2019 Wind gusts should gradually decrease throughout the day as a low pressure system moves northeast. Quieter weather will prevail this afternoon and tonight as high pressure builds over the Ohio River Valley. With a strong low pressure system jetting to the northeast and high pressure building over the Ohio River Valley, wind gusts have improved a great deal. Elevations above around 2500 feet may still see occasional gusts upwards of 50 mph, so have left the advisory in place until 10AM for the highest elevations. A gradual clearing trend from the southwest is expected by early afternoon under building high pressure. Seasonably cool conditions are expected to be reinforced on Saturday with the encroachment of another cold front.
1255 PM CDT Fri Nov 1 2019 Warmer and continued sunny today with highs in the 50s. A cold front moves through tonight, but will not be accompanied by precipitation. This will lead to a cooler day Sat with highs in the mid 40s to around 50 and breezy northwest winds. A dry cold front will veer winds to the northwest after 00z. High pressure will move in behind the front.
Opted to upgrade the freeze watch to a warning and expand further southwest as the drier air and radiational cooling conditions will allow minimums to skirt the freezing mark around sunrise Saturday. While higher dewpoints in the east will keep minimums from lowering to freezing, it will still be cold enough for areas of frost.
118 PM CDT Fri Nov 1 2019 Quick update to PoPs in association with another impulse rotating around the upper level low in southwest Ontario. The base of a low amplitude trough aloft will move through the forecast area throughout the day. At the surface, a cold front has already progressed through, with cold air advection and light precipitation along and behind the frontal boundary. Widespread cloud cover is helping keep current temperatures in the low to mid 30s, but that cloud cover, combined with cold air advection, will also limit daytime highs today to the upper 30s.
A very stable pattern due to high pressure off the West Coast will remain for the next several days keeping the weather dry. Otherwise, expect at least one more chilly night tonight, as lows will well below freezing in the Kern County desert and mainly in the mid 30s to low 40s in the San Joaquin Valley, although the coldest locations may briefly drop to around freezing. Highs on Saturday are expected to trend a little warmer compared to today as the Rex Block pattern (high pressure ridge off the coast of Central California and the Pacific Northwest with a weak upper-level low to the south, or off the coast of Baja California) will persist off the West Coast.
SHORT TERM (Tonight through Saturday Night):The 12Z NAM and 12Z GFS currently indicate a weak coastal trough developing across the western Gulf of Mexico tonight with low to mid level moisture across the western Gulf moving towards the lower Texas coast late tonight into early Sat morning. The reinforcing cooler air will provide temperatures in the lower to mid 70s Sat afternoon. Lows Sat night will be cooler than tonight especially across the northern ranchlands.
A cold front was moving across Minnesota early this morning. Ahead of this front, temperatures rose a few degrees from last evening, with several areas above freezing across southern Minnesota as of 3 am. The low level moisture has been lagging behind this front and once the low level moisture does increases this morning across eastern Minnesota, stronger forcing will weaken or end. All of these waves appear rather weak and therefore confidence in precip coverage is very low - hence the low PoP continues.
an upper level trough and associated cold front move through the area today bringing north winds gusting to around 30 mph and an increase in cloudiness. High temperatures range from 35 to 40 degrees in far eastern Colorado to the low to upper 40s east of the CO/KS border, warmest in Norton and Hill City areas. High temperatures are expected to range from the mid to upper 40s in far eastern Colorado to the low/mid 50s east of the CO/KS border. Low temperatures range from the mid to upper teens to around 20 in far eastern Colorado to the low to mid 20s elsewhere.
1148 AM CDT Fri Nov 1 2019 Today-tonight: Cold front should sweep across most of the forecast area during the day with little fanfare.
Lows tonight will be a few degrees warmer than what we're seeing this morning given a much warmer starting point, but highs tomorrow should be back into the 40s across the area. The frontal passages should be dry until deeper moisture is able to build into the region by mid week as high pressure finally moves off to our east. The combination of enhanced moisture and lift along any mid to late week cold front will likely generate some precipitation, though guidance differences are great enough that it's difficult to know when this will occur. A cold front will pass through the terminals late tonight, but no precipitation is expected.
159 PM EDT Fri Nov 1 2019 The first real cold front of the season will ever so slowly push its way over or just south of Lee County before becoming stationary.
QPF amounts will be on the low side. The broad 500mb trough in place across much of the northeastern three-fourths of the continental U.
255 PM CDT Fri Nov 1 2019 A weak cold front will move through central and eastern Illinois tonight bringing clouds and only spotty light rain and light snow. Cooler temperatures can be expected Saturday due to clouds and a brisk westerly wind.
1250 PM CDT Fri Nov 1 2019 GOES water vapor imagery early this morning showing a mid-level trough digging southeast through the Dakotas. This was pushing a surface cold front through central MN/western IA. The cold front will swing east through the area today with increasing low level lapse rates in daytime heating. Mid-level trough/cyclonic flow moving through tonight into Saturday morning expected to shake out a few snow showers. The trough departs east Saturday afternoon with a ridge of high pressure building in from the Plains. Ridge of high pressure moves overhead Saturday night but cloud cover ahead of next system dropping into the Northern Plains will send more clouds into the area.
Stratocu will diminish from west to east the remainder of the afternoon and into the evening with building high pressure. Seasonably cool conditions are expected to be reinforced on Saturday with the encroachment of another cold front.
Issued by National Weather Service Pueblo CO 1130 AM MDT Fri Nov 1 2019 Satellite pictures are showing some mid and upper level cloudiness moving across the CWA this morning associated with a weak upper trough. Downward motion behind the upper trough will be in place today and tonight for the CWA.
253 PM EDT Fri Nov 1 2019 Expecting VFR to prevail at the sites through the period, now that the low clouds have cleared out. Some models indicate the low level moisture lingers overnight, so I have brought SCT025 or so back into TYS and TRI overnight.
Temperatures will remain cool, with highs remaining below normal, especially in the lower valleys due to an inversion. High pressure at the surface and warming aloft, along with cold air trapped at the surface, resulted in a strengthening inversion for the lower valleys, including the Treasure Valley and Western Magic Valley.
1252 PM CDT Fri Nov 1 2019 An upper level trough will move through the area today, which will bring warmer conditions with decent mixing. With the passage of this trough and the decent mixing will come increased northwest winds, but not too overly breezy. Expecting lows in the upper 20s, possibly a touch cooler in south central SD where winds could be lighter.
Some models suggest that the low level moisture that produced the cloudiness earlier today will still be lingering overnight, so grids show a bit of scattered clouds mainly over the Valley beginning late tonight. We should stay under the influence of the upper trough throughout this forecast period, that sends several reinforcing shots of cold air our way, keeping temps at or below seasonal normals through the period.

A band of light to moderate snow generally between US Highway 83 and ND Highway 3 as of 1915 UTC will continue to propagate southeast in association with an impulse rotating around the upper level low across southwest Ontario.
Plenty of sunshine has finally broken through the persistent cloud deck allowing for daytime temperatures to reach above freezing in the high plains and upper 20s in the western portions of the CWA. As a region of high pressure settles in across the region west to northwest flow will take hold on Saturday with stacked height gradients across the Craig to Arlington line. Main threat will be the high sustained winds between 40 and 45 mph with gusts up to 60 mph.
Another cold front will push across West Central Texas tonight. lows tonight will be in the 30s, and highs on Saturday will be much cooler than usual early November highs. Both bring an upper trough in the northern Baja California area by mid week.
As high pressure remains fixed over the region. /issued 359 AM CDT Fri Nov 1 2019/ As of this writing, the surface freezing line extends from west to east across central Louisiana making the freeze warning issued yesterday afternoon look like a good call. On the other side of the spectrum, some areas along the I-10 corridor to the coast are still observing winds between 5 and 10 MPH which is providing enough mixing to keep temperatures in the lower 40s. High pressure nearly overhead will keep winds very light out of the northeast while extremely dry air aloft will keep skies clear. This will likely keep overnight lows tonight a few degrees warmer although some patchy frost will still be possible across parts of central Louisiana and points north.
High pressure was anchored off the coast of northern California with a ridge extending north into the Gulf of Alaska. A broad trough of low pressure was located across the entire CONUS this morning. With dry air in place, and westerly winds, this will facilitate good cold air drainage tonight and have trended lows toward the cooler MET guidance. On Saturday, a warm front will lift from west to east across the forecast area. The MAV was warmer and given the degree of expected mixing and full sun Saturday afternoon, trended temps more toward the warmer MAV guidance. This will force a back door cold front into the northeast forecast area Saturday night. This will lead to lows in the lower 30s.
