This is due to elongated surface ridging with an axis generally across the Texas Panhandle into the Mid-South. Our main source of cloud cover will be from troughing over the Desert Southwest, however, no precipitation is expected from it at any time this weekend. Northeasterly winds, by tonight, will become light and variable as the ridge axis lingers nearby, allowing minimum temperatures to fall into the 50s (slightly below normal in some areas). Atmospheric subsidence in combination with dry air, will give a small boost to maximum temperatures that reach the low-to- mid 80s (or higher in Deep East Texas) tomorrow afternoon.
1230 PM CDT Sat Oct 8 2022 The high clouds persist, temperatures are still on track for the upper 60s. Northwesterly, nearly meridional, flow continues over the Northern Plains between deep eastern CONUS troughing and a west coast ridge. As a warmer 850mb air mass has moved over the region this morning and will persist through the weekend, seasonably warm temperatures are expected with highs generally in the 60s and morning lows in the 30s.
So could see min temperatures, in the low 40s, similar to last night, even with most of the cold advection ending. Prefer to stay cooler than most guidance numbers for low temps, with the clam winds and clear skies expected.
1209 PM CDT Sat Oct 8 2022 (Today and tonight) Light showers and cooler temperatures are expected for Saturday, with current temperatures ranging from the 40s in northern and central Oklahoma, up to the 50s and low 60s in southern Oklahoma and western north Texas. Continuing with recent trends with the ongoing precipitation, models have been warmer with temperatures than recent observations. As such, forecasted temperatures are expected to be cooler than model guidance, with highs remaining below 70 across the region except for far southeastern Oklahoma and portions of western north Texas, and highs only reaching the mid 50s under areas impacted by the clouds/precipitation.
216 PM MDT Sat Oct 8 2022 High pressure has moved over Wyoming today, bringing mostly sunny skies and relatively light winds with near normal temperatures. Certainly can't rule out a few areas again developing similar clouds/fog Sunday morning as the high pressure warms the mid levels and caps near surface moisture.
306 PM CDT Sat Oct 8 2022 High pressure continues to dominate the region. Satellite imagery shows the high gradually making its way southeastward across the area. Kirksville dipped to 28F with STJ taking the lowest observed temperature of our ASOS sites at 26F; however, it is important to note that the STJ ASOS is about as low into the the MO River valley as you can go, so it is likely the residents of St. Joseph were slightly warmer. Tonight, low temperatures are expected to be relatively warmer, around 40F, alleviating frost/freeze concerns. As the high migrates across the area today, winds turn more southerly pushing warmer air into the region.
136 PM MDT Sat Oct 8 2022 Latest upper level analysis has northwest flow across the Northern Plains, with ridging off to the west.
252 PM EDT Sat Oct 8 2022 High pressure and a cool, dry airmass will remain in place across the region through the weekend.
320 PM EDT Sat Oct 8 2022 Dry forecast and near to below normal temperatures continues through the next several days, with high pressure dominating the area from the north.
200 PM PDT Sat Oct 8 2022 Low pressure, centered over the northern Gulf of California, will continue moist easterly flow over Southern California through the weekend.
This front will bring drier air vs cooler air, meaning temperatures today will not be too far different than we have experienced in previous days with highs in the upper 80s to lower 90s. The drier air will lead to noticeably cooler temperatures tonight, with lows dipping into the lower 60s for much of the inland locations, to the mid-to-upper 60s along the Rio Grand, to the lower 70s along the coast.
High pressure remains in place over the region. Overnight lows tonight will range from the lower 60s to the north and near 70 further south.
As we remain under general troughing aloft, a cool night will be in store. Continued with the trend of favoring cooler lows tonight. Overnight lows will range from the lower 40s in the Golden Triangle to the lower 50s along the Highway 84 corridor.
However, a warm air advection scheme sets up with the upper ridge building onto the High Plains and downslope flow continuing at H85. Thinking temperatures should mostly hold above the freezing mark. Given fair skies and decent mixing, this should translate to max temps in the lower/mid 70s.
343 PM EDT Sat Oct 8 2022 (This evening through Sunday) The cold front that pushed through over the last 24 hours or so is now draped west-to-east along the Gulf Coast and a dry airmass is spilling across northern and western Georgia in its wake. In a similar vein, have adjusted low temps tonight/early tomorrow morning down a couple degrees, which has introduced the potential for *very* patchy frost at the higher elevations of northeast Georgia. Another dry, mostly sunny day is on tap tomorrow with highs in the upper 60s to lower 80s, with the higher terrain of far north GA topping out in the low-to-mid 60s.
As this trough continues to push towards the east, higher surface pressure will settle in. Temperatures this evening will be in the low 50s for most places, and in the upper 40s across northern Oklahoma where breaks in the clouds appear possible which will allow for more radiational cooling.
Water vapor imagery highlights Tropical Storm Julia strengthening near the Gulf of Honduras, an upper low nearing the Greater Antilles, and a mean layer ridge covering the Gulf of Mexico and the extreme western North Atlantic. Temperatures are in the lower to mid 80s with dewpoints now in the lower 70s. With high pressure established over the southeastern US and the western North Atlantic, moderate to occasionally fresh northeast to east breezes will peak and lull for the next several days.
142 PM EDT Sat Oct 8 2022 High pressure will settle into the Ohio and Tennessee Valleys through tonight. The high will continue to extend across the region on Sunday.
A low pressure system spinning along the southern Arizona border will remain in place through Sunday leading to afternoon showers and thunderstorms over northwest Arizona and southeast California.
Mid level cloud cover will continue to spread over eastern Oklahoma, which will help keep temperature a few degrees cooler than yesterday, while most of northwest Arkansas will see mostly sunny skies all day.
(This afternoon through Sunday) It's cooler out there today with a slight breeze and high clouds exiting to the east. High pressure will continue to build over the Southeast region tonight as chilly conditions develop with clear skies and light to calm winds. The forecast continues to mirror some of the cooler model solutions with low temperatures in the mid to upper 30s possible in our cool, valley locations of the northeastern counties. Mostly sunny skies again tomorrow with temperatures remaining several degrees below average as ridging holds strong over the area.
(Through Sunday) High pressure will slide in from the west behind today's dry cold front. Daytime highs are expected to be in the low to mid 80s with overnight lows in low 50s to the north and the upper 50s near the Gulf Coast.
Temps Sunday should be a little warmer than today.
For Tonight, dry northwest flow aloft and surface ridging will produce good radiational cooling conditions allowing temperatures to drop into the 30s over much of the area. For Sunday, surface ridging and dry airmass remains.
(This evening through Sunday) The quasi-stationary upper low that has been over the Sea of Cortez has begun to shift to the northeast, and by the end of the day Sunday it should be centered near the Mexican border south of Tucson. Deep moisture continues to stream northward ahead of the low and will continue to feed scattered shower activity across the forecast area.
1222 PM CDT Sat Oct 8 2022 Seasonally cold high pressure will slide south of the area this morning and allow a westerly winds at the surface to develop.
(This evening through Sunday Night) The weak cold front from this morning has since moved offshore into the Gulf of Mexico. On Sunday, high pressure at 850mb will be firmly over E/SE Texas, keeping mostly clear skies and relatively quiet during the day. This will bring slightly cooler temperatures than that of today, though highs will still be in the 80s with a few inland locations looking to break 90 degrees. Lows on Sunday night will be relatively the same to that of the previous night, if not slightly cooler.
A ridge maintains quiet weather into the start of the work week. Sunday remains seasonally below high normals for this time of year; however, temperatures will be a couple of degrees warmer than Saturday with a light southerly flow returning.
A cold front that moved over the forecast area earlier today continues to move south over the Gulf, with cooler and drier air overspreading the area. With the cooler air expected to push over the area later today into tonight into Sunday, the full effects will be slower allowing temperatures today to range from the upper 70s north of Highway 84 to mid 80s over the I-10 corridor, a bit above seasonal norms. Tonight, as cooler air continues to overspread the forecast area, temperatures drop below seasonal norms, with clear skies and a dry airmass allowing for more efficient radiational cooling. Sunday, the pleasant and cooler forecast continues, with high temperatures ranging from the mid 70s along and north of Highway 84 to the low 80s along the I-10 corridor.
Going into Sunday, southerly flow sets up once again with a lee-side trough developing over eastern Colorado and high pressure east. This will allow for a warmup to occur lasting towards midweek before a cold front arrives.
(Tonight through Sunday night) Northeasterly winds and drier air in the low-levels have moved into south central Texas behind a cold front. Afternoon highs are still on track to peak in the lower 80s to near 90 degrees.
These are in cyclonic flow from a low pressure system near Hudson Bay. Sunday temperatures will only reach into the low to mid 60s with light and variable winds.
1128 AM MDT Sat Oct 8 2022 The blocky amplified pattern in place refuses to budge with a Rex Block in the West and deep trough in the East. About the only exciting feature weather-wise is a wave cresting western ridge tonight and dropping into the Intermountain West by late tomorrow.
This will also be in conjunction with a dry cold front that passes through the area today and tonight. With high pressure remaining continuing to remain quasi-stationary across the eastern conus, fair weather is expected to continue.
128 PM CDT Sat Oct 8 2022 (Today and tonight) Much of the southern Plains continues to be influenced by a broad trough over the eastern US and a closed low over the Desert Southwest. Meanwhile, a surface cold front has settled in along the I-10 corridor. The extensive cloud cover, along with the slightly cooler airmass behind the front, should be a slight limiting factor for warming sunshine today. So high temperatures were lowered by a few degrees for today, but should still range from the lower 70s to mid 80s. Better chances exist late tonight north of I-20 as a weak impulse ejected by the closed upper low moves across north Texas.
A weak cold front moved through the area this morning, lowering dewpoints throughout the area. The winds behind the front will provide some slight cold air advection into the area tonight, so because of that, lows will be slightly cooler tomorrow morning in the mid 50s to low 60s versus the mid 60s and low 70s this morning.
Some locations may see temperatures drop below freezing, especially in the typical cold spots. Precipitable water values are expected to be around 50% of normal for most of the area, with the exception of portions of southeast Missouri where they will nudge a bit higher on the west side of the ridge. Overnight lows are expected to drop into the low to mid 30s, with the typical cold spots possibly falling below freezing.
Some cirrus will move in overnight, but mostly clear skies are still expected and dewpoints will remain down in the low to mid 30s. Also there is potential for some of our typically colder spots to briefly reach the freezing mark, such as Fentress County, but not enough confidence for a freeze warning anywhere. Tomorrow will be another cool day albeit a few degrees warmer than today with highs in the low 60s Plateau and mid 60s to low 70s elsewhere.
1241 PM CDT Sat Oct 8 2022 (Today through Sunday Night) High pressure and northwest flow aloft will give way to calm and dry conditions through the short term period.
Pattern change with slightly cooler temperatures early to mid week. High pressure over the region will bring little change to the weather pattern today, as another day of warm and dry conditions prevail.
625 PM CDT Sat Oct 8 2022 (Tonight through Sunday night) The cold front is slowly oozing through Texas today and tomorrow and is forecast to be south of the CWA by Sunday evening.
512 PM MDT Sat Oct 8 2022 Latest upper level analysis has northwest flow across the Northern Plains, with ridging off to the west.
Ridging has been and will be in firm control over southern Oregon and far northern California, resulting in a forecast with very little day-to-day variation. Conditions along the coast and into the Umpqua Basin will be cooler thanks to the marine layer influence, and daily pushes of overnight and morning fog and stratus. The ridge is not impenetrable however, as it will retreat ever so slightly to the west as a series of smaller scale troughs ride over the ridge and dig south over the western U.
1000 PM EDT Sat Oct 8 2022 High pressure continues to build across the area tonight with a clear sky and dry air. For Tonight, dry northwest flow aloft and surface ridging will produce good radiational cooling conditions allowing temperatures to drop into the 30s over much of the area. For Sunday, surface ridging and dry airmass remains.
630 PM CDT Sat Oct 8 2022 (This evening through Sunday Night) The weak cold front from this morning has since moved offshore into the Gulf of Mexico. On Sunday, high pressure at 850mb will be firmly over E/SE Texas, keeping mostly clear skies and relatively quiet during the day. This will bring slightly cooler temperatures than that of today, though highs will still be in the 80s with a few inland locations looking to break 90 degrees. Lows on Sunday night will be relatively the same to that of the previous night, if not slightly cooler.
Despite the sunshine, temperatures are generally running a few degrees cooler than at this time yesterday. This as the ridge of high pressure that's been focused over the NErn Pacific and West Coast has begun to move slightly farther offshore. The offshore ridging pattern will maintain a shallow marine layer and light onshore flow, meaning another night of low stratus, fog and coastal drizzle is expected. This wave will eventually merge with a closed upper low, currently over northern Mexico, and will help to maintain cooler but seasonable temperatures across the CWA. Latest satellite imagery, ASOS obs, and webcams show the low level moisture mixing out or eroding back to the coast. KSFO Bridge Approach. Light to moderate northerly winds will prevail over the coastal waters as high pressure remains over the Eastern Pacific.
602 PM CDT Sat Oct 8 2022 (Remainder of today and tonight) Mid-level west-northwesterly flow of 30-40 knots persists across the region this afternoon, as the TN Valley remains along the southern rim of stronger cyclonic flow aloft associated with a longwave trough encompassing much of eastern North America.
The expectation is for the low and attendant front to slowly sink south overnight and into Sunday morning. No precipitation is expected with the front with dry low and mid levels, but high level cloud cover will start increasing early in the morning, and temperatures on Sunday will be slightly cooler than today, with highs in the 60s. These are in cyclonic flow from a low pressure system near Hudson Bay. Sunday temperatures will only reach into the low to mid 60s with light and variable winds.
A low pressure system will linger over northwest Mexico and southern Arizona with a chance of showers and thunderstorms through the rest of the weekend. Low pressure continues to meander around the region bringing enough moisture/instability for showers/storms. Expect similar conditions again on Sunday as the low pressure system remains in the region.
617 PM CDT Sat Oct 8 2022 High pressure continues to dominate the region. Satellite imagery shows the high gradually making its way southeastward across the area. Kirksville dipped to 28F with STJ taking the lowest observed temperature of our ASOS sites at 26F; however, it is important to note that the STJ ASOS is about as low into the the MO River valley as you can go, so it is likely the residents of St. Joseph were slightly warmer. Tonight, low temperatures are expected to be relatively warmer, around 40F, alleviating frost/freeze concerns. As the high migrates across the area today, winds turn more southerly pushing warmer air into the region.
703 PM EDT Sat Oct 8 2022 (Through Sunday) High pressure will slide in from the west behind today's dry cold front. Daytime highs are expected to be in the low to mid 80s with overnight lows in low 50s to the north and the upper 50s near the Gulf Coast.
/NEW/ /Through Sunday Evening/ North and Central Texas will remain situated between a cut-off low over the Desert Southwest and a deep upper trough over the Eastern CONUS for the remainder of the weekend.
(This evening through Sunday) The cold front that pushed through over the last 24 hours or so is now draped west-to-east along the Gulf Coast and a dry airmass is spilling across northern and western Georgia in its wake. In a similar vein, have adjusted low temps tonight/early tomorrow morning down a couple degrees, which has introduced the potential for *very* patchy frost at the higher elevations of northeast Georgia. Another dry, mostly sunny day is on tap tomorrow with highs in the upper 60s to lower 80s, with the higher terrain of far north GA topping out in the low-to-mid 60s.
Overnight lows in the lower 60s north to around 70 south, with Sun afternoon highs in the mid/upper 80s. High pressure remains in place over the region. Overnight lows tonight will range from the lower 60s to the north and near 70 further south.
Despite the sunshine, temperatures are generally running a few degrees cooler than at this time yesterday. This as the ridge of high pressure that's been focused over the NErn Pacific and West Coast has begun to move slightly farther offshore. The offshore ridging pattern will maintain a shallow marine layer and light onshore flow, meaning another night of low stratus, fog and coastal drizzle is expected. This wave will eventually merge with a closed upper low, currently over northern Mexico, and will help to maintain cooler but seasonable temperatures across the CWA. KSFO Bridge Approach. Light to moderate northerly winds will prevail over the coastal waters as high pressure remains over the Eastern Pacific.
A mid level ridge axis remains overhead with 500 mb heights holding near 591 Dm for at least the past 24 hours, with narrow lower tropospheric ridging across the central Florida Peninsula. While upper troughing remains broad across the northeast quarter of the Lower 48, the sharper lower level trough has exited the Mid Atlantic to the east. With the narrow but building western Atlantic ridge seems soon to dominate the northeast flow around the sprawling south central U. Also, a Coastal Flood Statement remains in effect for all the Florida Keys, and boaters should allow more slack in spring and dock lines, and be mindful of less clearance under fixed bridge during high tide.
Light winds are noted along the axis as well, extending into central IL, but toward northern IL a light 5 mph movement is noted farther north of the ridge axis. Dewpoints are mainly low to mid 30s, and should provide little resistance to temperature falls until near the freezing mark. The region is currently in northwest flow aloft with a cool, high pressure ridge at the surface over southern IL. The high will slowly sag south tonight, keeping parts of east-central IL in a light wind area. Warmer air will push in from the west on Sunday, with highs in the upper 60s to low 70's.
624 PM CDT Sat Oct 8 2022 (Tonight through Sunday night) Northeasterly winds and drier air in the low-levels have moved into south central Texas behind a cold front. Afternoon highs are still on track to peak in the lower 80s to near 90 degrees.
(Tonight) Quiet/seasonably cool wx conditions prevail across the central TN Valley this Sat evening, as a strong dome of high pressure out of the Plains states gradually builds eastward into much of the region. Current temps have fallen mainly into the lower/mid 50s, compared to their earlier highs in the upper 60s/lower 70s. With clear skies/light winds, coupled with dew pts in the lower/mid 30s, overnight lows still look to fall predom into the mid/upper 30s for most spots.
745 PM EDT Sat Oct 8 2022 Strong and cool high pressure will settle over the Eastern States to start the upcoming week.
1028 PM EDT Sat Oct 8 2022 Strong and cool high pressure will settle over the Eastern States to start the upcoming week.
649 PM CDT Sat Oct 8 2022 (This evening through Sunday) The quasi-stationary upper low that has been over the Sea of Cortez has begun to shift to the northeast, and by the end of the day Sunday it should be centered near the Mexican border south of Tucson. Deep moisture continues to stream northward ahead of the low and will continue to feed scattered shower activity across the forecast area.
948 PM CDT Sat Oct 8 2022 High pressure overhead will continue to provide a benign weather pattern through the next couple of days.
A cold front sinking southward across Lake Superior tonight in combination with strong high pressure across the southern Ohio and mid Mississippi Valley region will increase the low level westerly gradient across Se Mi.
An amplified upper ridge positioned immediately offshore from the West Coast will aid in substantial subsidence across NWRN CA during the next 12-24 hours. Elsewhere, high temperatures in the 80s to low 90s will be probable across the interior, and that will remain the case through much of the next seven days as a large-scale ridge remains positioned over the region. And needless to say, the ridge will yield precipitation chances near zero during the foreseeable future. Northerly winds will continue to ease overnight through Sunday afternoon as a weak trough drop down from the Cascadia.
635 PM CDT Sat Oct 8 2022 (This afternoon through Sunday) It's cooler out there today with a slight breeze and high clouds exiting to the east. High pressure will continue to build over the Southeast region tonight as chilly conditions develop with clear skies and light to calm winds. The forecast continues to mirror some of the cooler model solutions with low temperatures in the mid to upper 30s possible in our cool, valley locations of the northeastern counties. Mostly sunny skies again tomorrow with temperatures remaining several degrees below average as ridging holds strong over the area.
405 PM MDT Sat Oct 8 2022 High pressure has moved over Wyoming today, bringing mostly sunny skies and relatively light winds with near normal temperatures. Certainly can't rule out a few areas again developing similar clouds/fog Sunday morning as the high pressure warms the mid levels and caps near surface moisture.
1119 PM CDT Sat Oct 8 2022 (Tonight) Quiet/seasonably cool wx conditions prevail across the central TN Valley this Sat evening, as a strong dome of high pressure out of the Plains states gradually builds eastward into much of the region. Current temps have fallen mainly into the lower/mid 50s, compared to their earlier highs in the upper 60s/lower 70s. With clear skies/light winds, coupled with dew pts in the lower/mid 30s, overnight lows still look to fall predom into the mid/upper 30s for most spots.
