Minor Impacts at coast & ICWW - Small Craft Advisory Conditions across Outer Waters High pressure conditions will dominate the weather pattern for today with dry weather, mostly clear skies, and cooler Autumn temperatures as the dry northerly prevailing flow settles over the forecast area. Overnight low temperatures will drop down into the mid to upper 50s for inland areas and in the lower to mid 60s for counties along the the coast.
(Today through Tuesday) The coastal low and associated upper level trough will finally push off the coast and into the Atlantic through today into tomorrow giving way to the upper level ridging to settle into place over much of the south. Ridging and high pressure will be the main story for the short term with dry and sunny conditions expected through at least Tuesday. With the pattern dominated by high pressure and little to no cloud cover temps will easily warm to the low 80s today at ~5-6 degrees above normal. Tomorrow will see much of the same weather with temps in the low to mid 80s (~10 degrees above normal) and clear skies.
Northern Arizona is still seeing the affects of anomalously high moisture across the state and a trough along the west coast. The parent upper level low is forecast to deepen while sliding southward along the Pacific coast today. As the upper low approaches today, southerly winds will also be on the increase, especially across western Arizona. Winds will remain gusty to the north/northeast of the higher terrain tonight as downslope winds develop.
628 AM EDT Mon Oct 13 2025 A coastal low will slowly drift offshore through mid week as dry high pressure builds in across the region.
551 AM CDT Mon Oct 13 2025 (Tonight through Tuesday) Dry northerly flow will continue as a slow-moving upper-level trough persists to our east, while a ridge expands across the Ark-La-Tex region. Temperatures will continue to trend upward, reaching the low to mid 80s on Monday and perhaps the upper 80s in a few locations on Tuesday.
611 AM EDT Mon Oct 13 2025 High pressure will allow for continued dry conditions with slightly above normal temperatures for the first half of the working week. A dry cold front will move through mid week, providing cooler temperatures for the second half of the week.
649 AM EDT Mon Oct 13 2025 A low pressure system heads off the mid-Atlantic coast today, then out to sea Tuesday. A dry front then pushes across midweek with cooler temperatures behind it.
535 AM CDT Mon Oct 13 2025 - Cooler mornings and warm afternoons through the week. However, lows should be a touch warmer than yesterday morning with mainly lower 60s expected. Highs are expected to be similar to Sundays with many areas reaching the lower 90s.
647 AM EDT Mon Oct 13 2025 Gradual improvement from west to east is expected today as the coastal low near the North Carolina-South Carolina border moves away from the region and high pressure brings in drier air.
- Little to no precipitation expected through the work week as high pressure builds into the region. Florida remains underneath an upper-level trough axis as a Nor'Easter moves up the east coast. High pressure will dominate through the week as the low moves up the east coast. As the upper-level flow becomes meridional, this will push the ridge axis east. Eventually, another trough axis and an attendant cold front are expected to approach the area. (12Z TAFS) VFR conditions will prevail throughout the TAF period as high pressure remain in control.
721 AM EDT Mon Oct 13 2025 High pressure will extend into the area today and linger into much of the week. At the surface, Low pressure near the Outer Banks of NC this morning will move away as time progresses, while High pressure builds in from the west. High temperatures will range from the lower to middle 70s across the Charleston Tri-County, to the lower 80s along the Altamaha River and vicinity. Lows tonight will range from the mid 50s far inland, to the lower 60s near the coast. Upper level ridging strengthens over the central CONUS by Tuesday, allowing dry conditions to continue across the region.
614 AM CDT Mon Oct 13 2025 Upper troughing ejects across the western Atlantic and Mid- Atlantic states today and upper ridging begins to build over the forecast area in its wake. We maintain deep layer northerly flow through Tuesday before the low to mid level flow turns more northeasterly and easterly by mid-week. With cool, dry air continuing to move across the area we can expect cool overnight lows in the lower to middle 50's and warm afternoon highs in the middle to upper 80's today through Tuesday night.
525 AM MDT Mon Oct 13 2025 - Unsettled weather this week 07z surface analysis had ridge over the CWA with clear skies and light winds. Water vapour loop had upper low/trough over the northwest CONUS with southwest flow aloft over the northern Plains. Evolution of the upper trough the main forecast driver this week. Today/Tuesday, upper low drops into the southwest CONUS as perturbed southwest flow impacts the CWA.
However, some high clouds moving in from Nebraska will likely prevent areas from reaching the freezing mark this morning. At first, the northeastward-moving rain will still have to battle a lot of dry air beneath the clouds, but with continued rainfall into the dry sub-cloud layer through the night, the low-levels should gradually begin to saturate and so there will be better ground coverage by late tonight into tomorrow morning.
610 AM EDT Mon Oct 13 2025 * Periods of rain and drizzle for today and early tonight, mainly across the eastern half of the CWA * A new high pressure area with cooler and dry weather is in store for the rest of the week. One lobe of a double barreled upper low is right overhead this morning. Little rain will fall to the west of the axis of the trough (strung between the two lobes). Warren should end up 5F above normal, while York will be about 10F cooler than normal.
603 AM CDT Mon Oct 13 2025 - Cooler today and tomorrow with highs in the dipping into the 60s and increasing rain chances this evening into Tuesday.
Conversely, strong easterly downslope winds have limited precipitation and kept temperatures above freezing in valleys like Missoula, resulting in far fewer impacts.
- Warmer this afternoon with showers returning tonight/Tuesday. As the day progresses, a low pressure system will track southward along the Pacific Coast, turning our wind flow southerly across Idaho and supporting a largely warmer and drier day today. We remain in strong southerly flow ahead of the low on Tuesday. We will likely reach low to mid 60s in warmer spots, especially where we can get downslope winds to aid with any warming and counter increasing clouds/precipitation.
River valley fog continues to mix out and current temperatures were in the upper 50s to the lower 60s. Upper level and sfc ridging will continue to keep skies clear with plenty of sunshine. Dry, quiet weather along with unseasonably warm temperatures will continue through the first half of the week due to broad ridging both aloft and at the surface.
Although roads will remain above freezing tonight, still use caution while driving along the Cascades and east. As the low swings southward, showers will begin to have a more south to north movement in the afternoon as the showers wrap around the low. Temperatures will be slightly warmer than yesterday, but they will still be 5 to 15 degrees below normal. Northeast to east winds will be elevated this afternoon into the overnight hours along the ridgelines of the Cascades.
740 AM EDT Mon Oct 13 2025 Weak troughing will linger across the area today, followed by a primarily dry cold front late Tuesday.
717 AM EDT Mon Oct 13 2025 A few light showers are expected over the ridges this morning. Dry and warm conditions are expected Tuesday with a building ridge.
With cloudy skies hindering daytime heating, cooler daytime highs are forecast today with western NV valleys being in the middle 50s to lower 60s range and Sierra communities seeing highs between the middle 40s to the lower 50s. For Tuesday and Tuesday night, the eventual inland track of the upper low center will determine where the greatest impacts will occur. While Mono County is targeted for potential convective snow bands Tuesday afternoon/evening to add to their snowfall total, additional swaths of moisture could spread farther north across eastern CA/western NV if the low moves close enough. However, if this low tracks farther south, these areas would see much less in the way of additional precipitation after the main Monday night-Tuesday morning round moves through.
Temperatures will continue to warm into the work week thanks to High Pressure, so unfortunately we won't be getting any closer to fall-like temperatures except in the mornings. (Tuesday Night through next Monday) Dry weather through the work week because of the aforementioned high pressure system lingering over us. That high pressure will flatten into the weekend, leaving us vulnerable to a trough moving in from the west. This trough appears to be of decent strength in the extended guidance, but it is too soon to say whether we will see any hazardous weather because of it. The strength and position of the trough continues to shift with subsequent runs of guidance, as it typically does at this time frame.
1155 AM MDT Mon Oct 13 2025 - Warmer this afternoon with showers returning tonight/Tuesday. As the day progresses, a low pressure system will track southward along the Pacific Coast, turning our wind flow southerly across Idaho and supporting a largely warmer and drier day today. We remain in strong southerly flow ahead of the low on Tuesday. We will likely reach low to mid 60s in warmer spots, especially where we can get downslope winds to aid with any warming and counter increasing clouds/precipitation.
-A Coastal Flood Statement remains in effect for the Lower and Middle Keys. Temperatures currently in the lower to mid 80s are on track to only come up a few more degrees at most. Due to higher high tides, especially near the Upper Keys, boaters should be aware of lower clearance underneath fixed bridges. From synopsis, low pressure departs the Northeast and Mid- Atlantic coastline today. High pressure builds in behind it across much of the eastern United States.
- Dramatically cooler Monday with increasing clouds and rain showers. - Scattered rain showers continue Monday night and early Tuesday as a warm front lifts north across SW KS. - Decreasing clouds and warmer Tuesday afternoon.
A broad cold front is moving through eastern WI with a broad area of cloud cover off to the east, with a lobe of high pressure dominating the local weather through the rest of today keeping us relatively clear. Cloud cover will begin to increase out of the southwest this evening and overnight as low level warm air advection increases to the south of the center of high pressure over northern Minnesota, with isolated showers possible after midnight through sunrise southwest of the Minnesota River. Forecast soundings from the RAP/HRRR are relatively dry in the lower levels and saturated just above the WAA layer such that much of this may end up as virga until the lower levels saturate, which is not expected to happen until the evening tomorrow per forecast soundings.
1220 PM CDT Mon Oct 13 2025 - High pressure keeps the bulk of the new week dry and seasonally mild. Patchy fog retains its nightly potential under high pressure that presages moclear skies and light/calm winds. The 00Z modeling tonight of the upper high is coming in stronger and nearer with its ridge center than previous nights. These first days of the week will see the warmest temps as the upper high translates practically overhead. The high ultimately shifts east by week's end, as broad troffing to the west drives a system our direction.
Temperatures currently are in the lower 70s primarily.
(This evening through Tuesday) Warm and dry conditions continue as upper level ridging remains in control. High temps today and tomorrow will warm into the low to mid 80s.
147 PM EDT Mon Oct 13 2025 Broad low pressure along the Mid-Atlantic coast will showers, gusty winds, and high surf through Tuesday. The low will eventually push well out to sea by a front midweek.
An upper ridge will build over our region from the west through midweek. A large upper trough over the western U.
331 PM EDT Mon Oct 13 2025 * Periods of light rain and drizzle for this afternoon and early tonight, mainly across the eastern half of the CWA * High pressure will build Southeast from the Upper Great Lakes with cooler and dry weather is in store for the rest of the week. Warren should end up 5F above normal, while York will be about 10F cooler than normal.
This pattern is being driven by deep northerly flow over the state, as it sits between high pressure and ridging over the Central U. , and stacked low pressure off the Atlantic Coast. 75") and subsidence from the ridging, cloud cover will be minimized outside of some afternoon cumulus. Under the mostly sunny skies, high temperatures will reach the upper 70s to low 80s today, with overnight lows falling to the low to mid 50s tonight. The airmass will warm some on Tuesday as the ridge moves a bit closer, with highs climbing to the low to mid 80s. In the mountains of north GA, temps will be about 5-10 degrees cooler than just mentioned.
-A Coastal Flood Statement remains in effect for the Lower and Middle Keys. Temperatures currently in the lower to mid 80s are on track to only come up a few more degrees at most. Due to higher high tides, especially near the Upper Keys, boaters should be aware of lower clearance underneath fixed bridges. From synopsis, low pressure departs the Northeast and Mid-Atlantic coastline today. High pressure builds in behind it across much of the eastern United States.
So ridge-trough, ridge-trough transition every couple days. WPC clusters all on board with this although with some variations in speed/strength of the trough/ridges. Result of the broad lift and increasing moisture should be an expansive area of light showers from Tue through Tue night - with the higher chances and bulk of accumulations trending for Tue night. > TEMPERATURES: a cold front pushed east/southeast across the forecast area this morning with cooler/colder air following in its wake. With ridging becoming more pronounced for the latter half of the week, milder air will return to the region.
Right now, this pattern isn't conducive to seeing any surprise pockets of freezing rain where it stays colder overnight.
- Weak cold front over the weekend brings a low chance (20%) for rainfall. (Tonight through Tuesday night) The ridge aloft is forecast to continue to strengthen into Tuesday, centering across northeast Texas.
108 PM EDT Mon Oct 13 2025 Cloud cover continues to clear out from west to east this afternoon as the coastal low near the North Carolina-South Carolina border moves away from the region and high pressure brings in drier air.
Tranquil weather conditions will prevail for the first half of the week as a persistent mid to upper level ridge continues to limit rain chances across Southeast TX. Light winds will continue over the region, along with high temperatures in the upper 80s to lower 90s and low temperatures in the 60s for much of the inland portions and in the lower to mid 70s along the coast.
An upper level low around the Carolinas will shift to the northeast and merge with a secondary upper low as it dives southward across the Mid Atlantic region into tonight. Between the departing upper trough/low and a building ridge across the Southern Plains, our region remains in a deep layer northerly flow and this will continue to keep a dry air mass in place across west central and southwest Florida with mostly rain-free conditions through the middle of the week.
239 PM CDT Mon Oct 13 2025 - Scattered showers will continue into tonight; additional showers possible across central KS Tuesday - Dry and mild conditions for midweek - Rain chances return for late week into the weekend As of 2 PM Monday afternoon, broad southwest midlevel flow remains across the central Plains with deep troughing across the western CONUS and ridging within the MS valley. The associated cloud debris will keep temperatures much cooler with highs expected to top out in the 60s across central KS. Transitioning beyond Tuesday, midlevel heights will amplify and retrograde across the lower Plains.
Light rain showers will persist along and north of Interstate 80 this morning, and while many area will only see a trace of rainfall, we continue to see enough forcing ahead of the cold front to lead to some visibility reductions in a few of these showers. The lower levels will slowly saturate this morning and additional isolated showers are possible. Highs in the lower to mid 70s look on track, with perhaps the coolest temps in the 60s across far northeast IL.
Not much has changed with the expected pattern and the forecast for this week, as we will remain in a dry N-NW flow through much of the week as a high amplitude ridge will be over the Plains and MS Valley.
139 PM CDT Mon Oct 13 2025 - High pressure keeps the bulk of the new week dry and seasonally mild. As advertised things appear little changed from 24 hours ago with deep troughing over the east coast, ridging here at home, and general deep troughiness over the west.
(Tonight through Tuesday) Upper-level high pressure will remain the dominant feature across the region, keeping warm and drier conditions in the forecast through Tuesday.
150 PM EDT Mon Oct 13 2025 A coastal low will slowly drift offshore through mid week as dry and warmer high pressure builds in across the region.
A ridge of high pressure will remain in place across the Lower OH Valley region today.
256 PM CDT Mon Oct 13 2025 - Cooler temperatures with highs mainly in the 60s today and tomorrow.
Cooler temperatures will occur today ahead of a slight warm up tomorrow afternoon thanks to some increasing easterly winds.
Elsewhere across the Northern Rockies, the morning will start off chilly, with lows in the low to mid-20s in western Montana and low to mid-30s across north- central Idaho. Afternoon temperatures on Tuesday will rebound and be closer to normal, in the low 50s in western Montana and low 60s in north- central Idaho.
1245 PM EDT Mon Oct 13 2025 Dry and warm conditions are expected Tuesday with a building ridge.
1227 PM CDT Mon Oct 13 2025 - Cooler today and tomorrow with highs in the dipping into the 60s and increasing rain chances this evening into Tuesday.
200 PM CDT Mon Oct 13 2025 - Dramatically cooler Monday with increasing clouds and rain showers. - Scattered rain showers continue Monday night and early Tuesday as a warm front lifts north across SW KS. - Decreasing clouds and warmer Tuesday afternoon.
330 PM EDT Mon Oct 13 2025 - Mostly Dry Until Late Week - Weekend Shower/Storm Chances - Mostly Dry Until Late Week A weakening cold front is coming through mostly dry today, but some mid and low level cloud cover will persist into Tue morning. This precipitation will be produced amid midlevel lift and moisture (above 700 mb) crossing the ridge and spreading over relatively dry low-level air. Wed is expected to be the coolest day of the week with highs in the lower 60s, which is pretty close to mid October normals.
(This evening through Tuesday night) Benign weather continues for most of the week as broad upper level ridge generally remains centered across the Gulf South. The main effects from this high is lack of rain via strong subsidence and above normal temps.
Weak troughing will linger across the area today, followed by a primarily dry cold front late Tuesday.
1201 PM EDT Mon Oct 13 2025 * Periods of light rain and drizzle for this afternoon and early tonight, mainly across the eastern half of the CWA * High pressure will build Southeast from the Upper Great Lakes with cooler and dry weather is in store for the rest of the week. Warren should end up 5F above normal, while York will be about 10F cooler than normal.
This is due to forcing from a northern stream upper trough shifting away, along with a strengthening upper ridge extending from the southern Plains and into the lower Great Lakes. A cold front across northwest IL and into WI will slowly move across the area tonight and will shift winds to the northeast.
730 PM EDT Mon Oct 13 2025 - Mostly Dry Until Late Week - Weekend Shower/Storm Chances - Mostly Dry Until Late Week A weakening cold front is coming through mostly dry today, but some mid and low level cloud cover will persist into Tue morning. This precipitation will be produced amid midlevel lift and moisture (above 700 mb) crossing the ridge and spreading over relatively dry low-level air. Wed is expected to be the coolest day of the week with highs in the lower 60s, which is pretty close to mid October normals.
617 PM CDT Mon Oct 13 2025 (This evening through Tuesday) Warm and dry conditions continue as upper level ridging remains in control. High temps today and tomorrow will warm into the low to mid 80s.
750 PM EDT Mon Oct 13 2025 A cool and mainly clear night is expected as high pressure builds into the region.
544 PM CDT Mon Oct 13 2025 - High pressure keeps the bulk of the new week dry and seasonally mild. As advertised things appear little changed from 24 hours ago with deep troughing over the east coast, ridging here at home, and general deep troughiness over the west.
617 PM CDT Mon Oct 13 2025 (This evening through Tuesday night) Benign weather continues for most of the week as broad upper level ridge generally remains centered across the Gulf South. The main effects from this high is lack of rain via strong subsidence and above normal temps.
527 PM EDT Mon Oct 13 2025 High pressure will extend into the region this week.
The closed low-pressure system that brought widespread precipitation to the region overnight through this morning is now centered just off the OR/CA border. Any lingering light rain/snow in the mountains will taper off through this evening as the low dives south.
At 00Z the Pacific upper low 36N/125W was slightly west of model forecasts, suggesting it will turn inland a little later and farther south than models predict for Tuesday.
- Areas of locally dense fog may develop late tonight into tomorrow morning near the I-80 summit and over the High Plains.
A low pressure system has dropped south of the area, allowing for mostly sunny skies and increasing offshore flow this afternoon.
646 PM CDT Mon Oct 13 2025 - Cooler temperatures with highs mainly in the 60s today and tomorrow.
1044 PM EDT Mon Oct 13 2025 A cool and mainly clear night is expected as high pressure builds into the region.
831 PM EDT Mon Oct 13 2025 Dry and warm conditions are expected Tuesday with a building ridge.
739 PM EDT Mon Oct 13 2025 Low pressure just off the coast of the Delmarva will continue to spread clouds and scattered rain showers across central New York tonight, before ending Tuesday morning as high pressure builds east into the eastern Great Lakes. The next cold front will sag south across region Tuesday night, supporting seasonably cooler weather, though remain on the dry side for the later half of the week. Some patchy hilltop fog may develop overnight across the Southern Tier and Finger Lakes where low stratus intersects the higher terrain.
* Temperatures will be well below normal most of the week, with freezing morning low temperatures across the Owens Valley and Southern Great Basin by midweek.
716 PM CDT Mon Oct 13 2025 An upper ridge will build over our region from the west through midweek. A large upper trough over the western U.
Current thinking is that the best chance for fog will be for areas generally west of I-135 where cooler temps are helping low levels saturate quicker. As of 2 PM Monday afternoon, broad southwest midlevel flow remains across the central Plains with deep troughing across the western CONUS and ridging within the MS valley. The associated cloud debris will keep temperatures much cooler with highs expected to top out in the 60s across central KS. Transitioning beyond Tuesday, midlevel heights will amplify and retrograde across the lower Plains.
