1040 PM PDT Wed Nov 1 2023 High pressure over the region today and tomorrow will result in above average daytime temperatures. A medium 500 mb high pressure ridge is located over northern California resulting in sinking, warming (drying) air aloft which is slightly reinforcing the lower level temperature inversion. In the hills and mountains in the forecast area within the lower level temperature inversion, air temperatures are relatively milder, however in the valleys and lower lying areas it's cooler to much cooler.
For today, temperatures will be warmer than yesterday, generally 70 degrees. Starting Friday, min humidity will be critical across the lowlands and 16 to 25 percent in the higher terrain.
1226 AM CDT Thu Nov 2 2023 (Tonight through Thursday night) Benign weather conditions can be expected to continue through the short-term period as the area generally remains under the influence of a high pressure system. Although in general not anticipating temperatures to reach freezing, this cannot be ruled out completely over low-lying drainage areas. Tomorrow will be warmer with highs in the upper 60s to low 70s, and overnight lows in the low 50s to mid 60s.
-Temperatures continue to warm up slowly Forecast Details: High pressure will continue to dominate the region today, keeping the area and the forecast dry for Thursday. Highs will be around 5 degrees cooler than normal, ranging from the lower 40s near the Upper Peninsula border to the middle 40s near the Fox Valley and lakeshore. Then, a weak cold front will cross into the region Friday morning, which will keep skies cloudy through the morning hours before some clearing builds in behind the front. High temperatures for Friday will be near normal, with highs ranging from the lower 40s near the Upper Peninsula to the lower 50s near the Fox Valley.
(This evening through Friday night) Strong ridging will remain in place tonight in the low to mid- levels of the atmosphere, and this will continue to keep a very dry and very stable airmass over the region. By tomorrow, the ridge axis will begin to pull to the east and a gradual warming trend will ensue across the region. Lows will easily fall into the mid to upper 30s over inland areas Thursday night, but highs will climb 30 to 35 degrees into the low to mid 70s by Friday afternoon.
239 AM EDT Thu Nov 2 2023 Tonight will be the coldest night since early Spring with widespread sub-freezing temperatures expected to end the growing season in central PA.
Closer to the water it's going to be pretty tough to get below freezing outside of the aforementioned basins so naturally left out the coastal zones. Today looks a little warmer than yesterday, but only by a few degrees. Surface pressure gradient should begin to tighten toward the end of the short term period as a rather broad low pressure across the western Caribbean Sea begins to interact with a 1020mb high across portions of eastern Tennessee and western North Carolina.
The upper- level ridge that brought us a few days of pleasant weather is breaking down allowing for more zonal flow aloft. Best moisture will be focused across the higher terrain the next few days.
With a breezy southerly flow, temperatures are expected to warm into the lower and mid 60s most places this afternoon.
Once the lows have been observed this morning we will adjust our freeze map and issue an additional warning if needed for those counties. As we work into Friday, look for another sunny day with high pressure to our east. Temperatures will be a few degrees warmer with highs in the upper 60s to low 70s.
1250 AM CDT Thu Nov 2 2023 (Tonight through Thursday night) Broad high pressure over the lower Texas coast and deep South Texas/RGV. Still seeing some after effects of the recent cold front. A weak short wave trough will transit over the middle and upper Texas coast Thursday and Thursday night, but other than a fe extra clouds, nothing germaine for our CWA. Temps will be slightly cooler that normal for another day, then above average starting Friday.
357 AM EDT Thu Nov 2 2023 High pressure will settle over the mid-Atlantic region today, remaining there through the weekend.
(Now through Thursday) Overall large scale upper troughing over the eastern CONUS will continue through the period. Last night, with the tighter pressure gradient the winds stayed up and most locations remained above freezing, with lows generally ranging from the mid/upper 30s to lower 40s across the area. Tonight as the high settles across the area and the gradient lessens, we expect much lighter winds, and with dewpoints still expected to be in the upper teens and lower 20s for most locations, we expect that temperatures will drop more significantly tonight. We do think that many inland locations away from the coast will likely see their first freeze of the season tonight, with lows ranging from the upper 20s up around the Highway 84 corridor, to the lower 30s further south all the way down to the I-10 corridor.
259 AM EDT Thu Nov 2 2023 Warmer today compared to the past few days, with highs in the upper 40s to low 50s. While lows drop to near to below freezing tonight, a hard freeze is not expected. Southwest winds could gust up to 20-25 mph at times today (and again Friday), transporting much warmer air northward. Tonight, lows will be near freezing with breezy conditions continuing.
Warmer temperatures today. High pressure over the Appalachians this morning will shift east through the day.
359 AM CDT Thu Nov 2 2023 (Issued 358 AM CDT Thu Nov 2 2023) Today and Tonight: First, will have to watch high temperatures for today as warmer southwest wind flow continues across southern Wisconsin.
A northern stream short wave and associated weak surface cold front move across the region Friday. Northern Lower looks like it will be warm enough for all rain while a little cooler air across eastern upper could lead to a few wet snowflakes mixing in at the onset.
251 AM CDT Thu Nov 2 2023 * Breezy and warmer conditions to close out the week Broad warm advection and attendant southwesterly breezes today will help boost temperatures back into lower 50s under generally sunny to partly cloudy skies. We begin on Friday evening when a departing low level jet will pull a broad center of low pressure into the area.
1121 PM MDT Wed Nov 1 2023 The H500 hand analysis map is showing low pressure dominating E. NOAM transitioning to a high pressure ridge along the NOAM Pacific coastline. extends from the PacNW across the Central Rockies to the base of the trough over the Gulf States. Otherwise the warming trend should continue as the Pacific ridge works farther inland. This warmup is expected to materialize with the deterioration of northwest flow and the progression of a ridge situated over the Mountain West. EC is keeping isoheights and thus temperatures, a bit higher on Friday afternoon versus the cooler GFS.
This precipitation includes freezing rain for the valleys of Southwestern Montana.
620 AM CDT Thu Nov 2 2023 * Breezy and warmer conditions to close out the week Broad warm advection and attendant southwesterly breezes today will help boost temperatures back into lower 50s under generally sunny to partly cloudy skies. We begin on Friday evening when a departing low level jet will pull a broad center of low pressure into the area.
556 AM EDT Thu Nov 2 2023 High pressure will settle over the mid-Atlantic region today, remaining there through the weekend.
1027 AM EDT Thu Nov 2 2023 Dry high pressure continues over our region through the weekend and into the next work week. Fair, cool, and dry across the region through the next 24 hours as a nearly zonal flow aloft hold high pressure at the surface over the Carolinas/Mid-Atlantic. Temps should recover maybe a category warmer this afternoon, but still on the order of ten degrees below normal, under lots of sunshine.
929 AM EDT Thu Nov 2 2023 High pressure, centered over West Virginia this morning, will slowly push to the Mid Atlantic coast over the next several days. Meanwhile, a dying cold front will stall out just north of the state this weekend.
Lows tonight will range from the lower to mid 30s over interior areas and in the upper 30s to lower 40s over much of the southern part of the region (except mid 40s to near 50 degrees along the immediate coast and beaches). Highs on Friday should trend a little warmer around 70 degrees to the lower 70s over much of the area.
/NEW/ Update: Models coming in slightly warmer west of I-35 this afternoon, then across much of the area by a couple of degrees on Friday, so made some minor adjustments. After another frost morning with lows in the upper 20s to mid 30s, highs will warm into the lower-mid 60s this afternoon with increasing southerly winds around 10 mph. Southerly breezes increase on Friday between 10 to 15 mph and gusty, as low pressure near the Front Range deepens.
358 AM MDT Thu Nov 2 2023 Mid and high clouds continued to stream through the high pressure ridge to the west moving southeastward overhead early this morning. Clouds remain in the picture today as a short wave trough moves to the West Coast this afternoon with altostratus largely confined to the northern zones. The short wave tracks eastward over the Northwest and northern Great Basin tonight forcing the ridge eastward while it loses amplitude over the region later tonight and clouds decrease. If showers develop they shouldn't be very impactful with model output only generating an inch or two of snowfall over the higher peaks.
940 AM EDT Thu Nov 2 2023 It was another cold start to the day after morning lows were generally in the low to mid 20s this morning with 30 for SDF. High pressure to our east will allow for increased southerly flow and the forecast is on track to see our afternoon temperatures warm into the mid 50s. Southwesterly return flow is forecast to increase today, especially north of the Ohio River, due to a tightening pressure gradient between the high and a low pressure system over Canada. Highs will likely be in the low to mid 50s. Light, but steady, southerly flow will also keep temperatures warmer tonight. Clear skies will still allow some sheltered rural areas to dip below freezing, with lows ranging from the upper 20s to mid 30s.
(Rest of Today) Below-freezing temperatures this morning have warmed into the low to mid 30s throughout most of the Tennessee Valley and are forecast to continue rising into the upper 50s to low 60s by this afternoon. High pressure to our east will allow us to have clear skies today and continued dry conditions.
This is due to ridging aloft over the western CONUS, north of a mid-level low and just west of Baja California. Onshore flow near the surface with high pressure over the southeast CONUS. Temperatures will top out in the low to mid 70s across the region today with overnight lows ranging in the 50s and 60s.
High pressure will remain along the Mid-Atlantic coast with a tight pressure gradient across the Florida peninsula.
1001 AM EDT Thu Nov 2 2023 High pressure will build into the area from the west and eventually overhead for the remainder of the week. 1034 mb high pressure is centered over the Carolinas and mid-Atlantic this morning with clear skies prevailing, outside of some straggling strato-cu lingering along the Outer Banks. The normally cooler sheltered locations could drop to or slightly below freezing once again with strong radiational cooling expected. Along the coast, northerly breezes will keep the lower levels mixed resulting in warmer lows in the 40s.
738 AM EDT Thu Nov 2 2023 Dry conditions with high pressure will continue into the weekend along with a gradual warming trend. Eastern CONUS high pressure and zonal flow will keep dry weather in the forecast through Friday. Mostly sunny skies are expected today, but increasing upper level moisture amid a crossing weak upper trough will bring increasing cloud cover on Friday. Most will be just below the freezing mark Friday morning.
some hints at the lower clouds clearing out esp south areas and this is where temps will be warmest peaking at in the low 40s in Richland county ND with low to mid 30s most other areas.
Highs today are forecast to climb into the low 60s to low 70s from north to south across the area. Either way, higher dew points would suggest slightly warmer low temperatures overnight.
Several valleys across west central and northwest Montana are still holding onto strong valley inversions which is keeping temperatures below freezing. These valleys will experience a mix of snow, rain and freezing rain throughout the morning hours. Several winter weather advisories are in affect for the areas that have the greatest chance of experiencing freezing rain this morning.
Wagner (Issued 358 AM CDT Thu Nov 2 2023) Today and Tonight: First, will have to watch high temperatures for today as warmer southwest wind flow continues across southern Wisconsin.
521 AM MDT Thu Nov 2 2023 Mid and high clouds continued to stream through the high pressure ridge to the west moving southeastward overhead early this morning. Clouds remain in the picture today as a short wave trough moves to the West Coast this afternoon with altostratus largely confined to the northern zones. The short wave tracks eastward over the Northwest and northern Great Basin tonight forcing the ridge eastward while it loses amplitude over the region later tonight and clouds decrease. If showers develop they shouldn't be very impactful with model output only generating an inch or two of snowfall over the higher peaks.
941 AM EDT Thu Nov 2 2023 High pressure will settle over the mid-Atlantic region today, remaining there through the weekend.
1028 AM EDT Thu Nov 2 2023 Dry high pressure continues over our region through the weekend and into the next work week. Fair, cool, and dry across the region through the next 24 hours as a nearly zonal flow aloft hold high pressure at the surface over the Carolinas/Mid-Atlantic. Temps should recover maybe a category warmer this afternoon, but still on the order of ten degrees below normal, under lots of sunshine.
Synopsis: Upper ridge over western NOAM is producing northwesterly flow aloft over the great plains. At the surface, a weak trough extends from the northern Rockies into northeastern Wyoming. High temperatures are expected to be 5-10F degrees warmer today than yesterday for much of the region.
Mid Atlantic high pressure will position Southeast Michigan in southwesterly gradient flow. An expansive 850mb ridge spreads across the Southeast states today, juxtaposed by the stationary Hudson Bay low. The gradient tightens further by Friday as the ridge moves out over the Atlantic and a weak cold front tracks into the northern Great Lakes. 925mb temps reaching the lower single digits C are supportive of highs closer to normal in the lower to mid 50s. The height falls driving the cold front will stay well to the north, and the orphaned front eventually looks to wash out over Lower Michigan Friday night.
Issued by National Weather Service State College PA 937 AM EDT Thu Nov 2 2023 High pressure will bring an end to any remaining lake effect snow showers this morning.
531 AM CDT Thu Nov 2 2023 (Today) High pressure at the surface in place just to our east across the southern Appalachians is promoting clear and calm conditions. The warmer conditions and dry air mass will create afternoon RH values at critically low levels between 20-25%.
948 AM EDT Thu Nov 2 2023 Dry conditions with high pressure will continue into the weekend along with a gradual warming trend. Eastern CONUS high pressure and zonal flow will keep dry weather in the forecast through Friday. Mostly sunny skies are expected today, but increasing upper level moisture amid a crossing weak upper trough will bring increasing cloud cover on Friday. Most will be just below the freezing mark Friday morning.
Temperatures already warm enough across most of the ridge tops for rain, and with afternoon timing of onset, river bottom temperatures should also support rain. While the ensembles have increased the potential QPF amounts with this system, the freezing rain threat has diminished somewhat, as the highest probability for 0. 10" of accumulation is across the southwest half of the CWA, where temperatures will be warmer.
The presence of high pressure and resulting weak pressure gradient will thankfully result in only light gradient winds. Warmer temperatures today. High pressure over the Appalachians this morning will shift east through the day.
Southwest Montana has a small chance of receiving light freezing rain this morning.
Issued a winter weather advisory for the Butte/Blackfoot Region due to concern for freezing rain, particularly along Interstate 90 from Drummond to Deerlodge. Several valleys across west central and northwest Montana are still holding onto strong valley inversions which is keeping temperatures below freezing. These valleys will experience a mix of snow, rain and freezing rain throughout the morning hours. Several winter weather advisories are in affect for the areas that have the greatest chance of experiencing freezing rain this morning.
635 AM CDT Thu Nov 2 2023 Cool, clear, and calm conditions are expected for the next few days as high pressure dominates.
Moderately gusty S/SW winds will continue along the coast this morning, and over ridges into this afternoon. This mild ridging will result in a break in precipitation for the majority of the region Friday morning ahead of another AR.
645 AM EDT Thu Nov 2 2023 Warmer today compared to the past few days, with highs in the upper 40s to low 50s. While lows drop to near to below freezing tonight, a hard freeze is not expected. Southwest winds could gust up to 20-25 mph at times today (and again Friday), transporting much warmer air northward. Tonight, lows will be near freezing with breezy conditions continuing.
644 AM EDT Thu Nov 2 2023 Dry high pressure continues over our region through the weekend and into the next work week. Fair, cool, and dry across the region through the next 24 hours as a nearly zonal flow aloft hold high pressure at the surface over the Carolinas/Mid-Atlantic. Temps should recover maybe a category warmer this afternoon, but still on the order of ten degrees below normal, under lots of sunshine.
Any showers should be ending Friday evening as the front clears the forecast area and surface ridging moves in. Southwest winds will hold temps above freezing tonight with cooler conditions for Friday night and sub-freezing temperatures returning across the northern zones.
Widespread rain post warm front continue across much of the forecast area this morning. Cold front is seen approaching the area from the northwest and should reach Baker City and Burns around 22z continuing southeast into the Treasure Valley around 00z and the Western Magic Valley around 05z.
As temperatures rise above freezing across the area the freeze warning has been allowed to expire. After highs top out well into the 60s this afternoon, clear skies and light wind tonight will allow temperatures to drop to near or slightly below freezing, especially over eastern MS.
1248 PM CDT Thu Nov 2 2023 As temperatures rise above freezing across the area the freeze warning has been allowed to expire. After highs top out well into the 60s this afternoon, clear skies and light wind tonight will allow temperatures to drop to near or slightly below freezing, especially over eastern MS.
High pressure remains well off to our east, which places us under LLVL southerly flow. Today, much of the area has increased into the low-mid 50s, with some in our south reaching the 60s tomorrow.
An afternoon that's 10 degrees warmer than today seemed a stretch for what will be just insolation from weak sun angles (as opposed to actual advection).
Winds are noticeably lighter compared to last few days as the surface pressure field has broadened out within an elongated zone of high pressure stretching through the state.
Tomorrows high temperature will be in the low to mid 70s.
The southerly flow is aided slightly by height falls at 500 mb associated with slight sharpening of a trough at that level from today through early Friday. As the weak trough swings east of the Texas coast later Friday, warm advection should follow and help erase the inversion and allow more sunshine than today. If the clouds hold, lows could be a couple degrees higher than forecast (lower 60s in more areas) whereas if the clouds break more than forecast, temperatures could reach the low to mid 50s in a wider swath of the area due to radiational cooling under light winds.
208 PM EDT Thu Nov 2 2023 High pressure will slowly translate to the Mid Atlantic coast through Friday bringing dry and milder conditions. Meanwhile, a dying cold front will stall out just north of the state this weekend.
A weak upper level ridge will move into the area for Friday. 6 feet MSL for the high tide cycle this evening, remaining below advisory criteria.
Afternoon highs for today will be in the low to mid 70s with cooler weather in store after Friday.
(Through Friday) Seasonably cool and quiet conditions are expected to persist through the day tomorrow, with high temperatures generally remaining near average (in the 70s) and low temperatures remaining below average (from the low 40s in Alabama and Georgia to the low 50s in the southeast Big Bend).
(This afternoon through Friday) A cold and dry airmass remains in place over the Southeast as a high pressure center moves east over the Mid-Atlantic region. Highs will reach the low to mid 60s today then upper 60s to lower 70s tomorrow with plenty of sun and a mostly cloudless sky. We'll have another night with most areas at or below freezing.
(This evening through Friday Night) High pressure has moved eastward into the Gulf of Mexico, allowing onshore flow to return this afternoon. Lows tonight will be slightly warmer than the last couple of nights, with temperatures in the 40s and 50s. Lows on Friday night will be slightly warmer than tonight, with temperatures in the upper 40s to near 60.
Patchy lower elevation freezing rain will be around across Hill and Northern Blaine counties, especially in the Milk River Valley, tonight into Friday morning. Although this system is on the warm side, cooler air trapped near the Milk River valley and points northeastward will result in a freezing rain risk this evening into tonight in portions of Hill and Blaine counties.
1257 PM EDT Thu Nov 2 2023 High pressure will settle over the mid-Atlantic region today, remaining there through the weekend.
Temperatures will continue to climb today and tomorrow, with afternoon highs mostly in the 60s this afternoon and in the low 70s tomorrow. Tonight will be another chilly night, but most locations should remain above freezing with lows in the 40s.
That pattern consisting of a western CONUS upper ridge, and eastern CONUS trof. S/W energy is progged to top the ridge and move southeast over the CWA tonight.
It was another cold start to the day after morning lows were generally in the low to mid 20s this morning with 30 for SDF. High pressure to our east will allow for increased southerly flow and the forecast is on track to see our afternoon temperatures warm into the mid 50s. Southwesterly return flow is forecast to increase today, especially north of the Ohio River, due to a tightening pressure gradient between the high and a low pressure system over Canada. Highs will likely be in the low to mid 50s. Light, but steady, southerly flow will also keep temperatures warmer tonight. Clear skies will still allow some sheltered rural areas to dip below freezing, with lows ranging from the upper 20s to mid 30s.
An expansive 850mb ridge spreads across the Southeast states today, juxtaposed by the stationary Hudson Bay low. The gradient tightens further by Friday as the ridge moves out over the Atlantic and a weak cold front tracks into the northern Great Lakes. 925mb temps reaching the lower single digits C are supportive of highs closer to normal in the lower to mid 50s. The height falls driving the cold front will stay well to the north, and the orphaned front eventually looks to wash out over Lower Michigan Friday night.
Upper level ridge is located over the Rockies into the Northern Plains with increasing mid/high clouds across the forecast area. This will also lead to slightly cooler highs on Friday.
