1115 AM CST Sat Nov 16 2024 (Today through Sunday) High pressure is currently centered over the Great Lakes and Ohio Valley. The center of the high pressure will slide southeast, and will be centered over the Mid-Atlantic by sunset on Sunday. We will likely see some patchy fog this morning and then again Sunday morning, as the ground moisture remains and temperatures will fall quite substantially into into thew upper 30s to low 40s this morning and then a few degrees warmer on Sunday morning.
A low-pressure system will continue to bring scattered rain and snow showers to portions of Yavapai and Coconino counties through this evening. The low then moves south of the area on Sunday, with shower activity confined to the eastern Mogollon Rim and White Mountains.
1251 PM EST Sat Nov 16 2024 High pressure will extend across the region today. Despite the high, considerable cloudiness will persist. The high will move east of the area tonight into Sunday.
Mostly clear and warm with ridging and high pressure. Discussion: Ridging aloft and at the surface will produce a mostly clear sky and higher probability for fog tonight into Sunday morning, especially along the river valleys. Fog is expected to dissipate by mid-morning Sunday with warming conditions around 5 to 10 degrees above normal due to ridging and southerly flow across the Southeast CONUS.
High level clouds are streaming in from the northwest ahead of the next warm front with increasing clouds later today. Next warm front arrives into eastern OR late this evening, with precipitation reaching southwest ID by Sunday morning. Snow levels rise to 5000-7000 feet on Sunday afternoon ahead of the cold front. There is a threat of freezing rain in eastern OR as the transition occurs, but it will be short lived. Then winds increase on Sunday afternoon ahead of the cold front.

237 PM EST Sat Nov 16 2024 High pressure will provide for dry and mild conditions on Sunday. High pressure ridge axis will shift off to the east tonight. As it does, the low level flow will become southerly, helping to erode the lower clouds away from the southwest with mainly just some higher level clouds expected then through the rest of the night. Lows will range from the mid to upper 30s in the east to the lower 40s in the west. Some weak mid level energy will move across the Great Lakes Sunday night as the mid level ridge flattens out over head and a weak frontal boundary drops into our area from the northwest.
Afternoon satellite imagery shows some lingering low stratus in parts of the Snake Plain into the Arco Desert towards Craters and occasionally trying to sneak into the lower Wood River Valley. Temps this afternoon have been cold, with Pocatello still below freezing but areas that have seen a bit more sun have climbed above freezing but not by much.
Dome of high pressure will reign supreme across the area through the weekend.

541 PM EST Sat Nov 16 2024 High pressure builds into through Sunday, bringing dry weather and warming temperatures.
Concerning overnight low temperatures, should see much warmer temperatures given the insulating effects of the returning moisture to the extent that low temperatures tonight will likely be reached ahead of the returning cloud cover when hourly temperatures may begin to rise slightly with the onset of low level warm air advection as well. Thus, high chance to likely pops are warranted across most of our region with the highest rain chances across our western half where the better moisture transport will be located. By Sunday Night, we start to lose a lot of this isentropic forcing, especially across the I-20 Corridor and points south as we begin to focus our attention to areas near and northwest of the I-30 Corridor as we await deeper forcing from the upstream trough.
Widespread stratocu will persist through the night thanks to an inversion ahead of an incoming pre-frontal trough. The low PoPs in the forecast remain warranted, but am expecting little precipitation to reach the surface. The low levels are shown to be moist.
521 PM CST Sat Nov 16 2024 - Cooler but still above normal temperatures Sunday with highs in the 50s.
848 PM CST Sat Nov 16 2024 GOES-16 Water Vapor satellite trends show an upper-level ridge axis extending over the eastern half of the United States. Southwest flow on the back side of the ridge is resulting in slightly warmer temperatures this evening and some cirrus spreading across the region.
708 PM EST Sat Nov 16 2024 High pressure will provide dry and mild conditions through Sunday. High pressure ridge axis will shift off to the east tonight. As it does, the low level flow will become southerly, helping to erode the lower clouds away from the southwest with mainly just some higher level clouds expected then through the rest of the night. Lows will range from the mid to upper 30s in the east to the lower 40s in the west. Some weak mid level energy will move across the Great Lakes Sunday night as the mid level ridge flattens out over head and a weak frontal boundary drops into our area from the northwest.
Cold front moves through mid-week, bringing the next chance for rain, then colder, drier, and windier conditions by the end of work week. Lows generally in the low 40s. Key Message(s): - Dry weather and gradually warming temperatures With upper ridge taking hold through the short term period, warm temperatures are expected.

Temps rebound today while light rain move over the Redwood coast this afternoon as a warm front approaches. Widespread light to locally moderate precip sweeps through Sunday afternoon with a cold front. High and mid level clouds are streaming over Northwest California with the advance of a warm front moving toward the Pacific Northwest. The radar is showing plenty of echos over the Pacific off our coast but drier air in the low levels is likely not allowing much of this to reach the ground. As the atmosphere moistens today into tonight and the trailing cold front approaches, precipitation will start to reach the ground and become more widespread over areas north of Ukiah on Sunday.
958 PM EST Sat Nov 16 2024 High pressure will provide dry and mild conditions through Sunday. Amplified flow pattern with a full latitude ridge over the area building east of the region overnight.

Otherwise, for today, a mid level ridge axis will move east while a mid level disturbance pushes into the western Great Lakes. This feature will be associated with a weak cold front. Filtered sunshine and southerly flow will result in high temperatures ranging from the upper 50s to the lower 60s. This will advance the weak cold front southeast into our northern forecast area.
1222 AM EST Sun Nov 17 2024 - Cloud cover continues to keep us warmer at night, but a little cooler during the day through Sunday.
It will snow over the higher mountains of the WA Cascades through around 06Z before a transition to rain occurs and until around 12Z over the higher elevations of the northern Blues. The best chance to reach warning level snow will be after the rain changes to snow behind a cold frontal passage Sunday afternoon.
Otherwise, warmer today due to stronger ridging and southwest flow in place across the region. Warmer tonight with temps only dropping into the mid 40s.
1215 AM CST Sun Nov 17 2024 Tonight and Sunday: Another cool night for the ArkLaMiss region as a ridging pattern continues to influence weather conditions. Along the periphery of the ridge, an isolated showers can't be ruled out in SE AR and NE LA during the afternoon hours.

Discussion: Ridging aloft and at the surface will produce a mostly clear sky and higher probability for fog tonight into Sunday morning, especially along the river valleys. Fog is expected to dissipate by mid-morning Sunday with warming conditions around 5 to 10 degrees above normal due to ridging and southerly flow across the Southeast CONUS.
pdf High pressure at the surface and aloft builds over the forecast area through Tonight.
The warm front is currently over Central Oregon, bringing light precipitation and low clouds. However, the forecast is still on track with snow beginning in Eastern Oregon this evening and transitioning to freezing rain by the very early morning.
As an upper ridge axis builds back into the area today, our winds will veer to the south to southwest, helping to reinforce this warm air mass. Despite the scattered high clouds, southerly flow will push highs a few degrees warmer and into the lower 70s in most locations.
The sounding also shows the little bit of moisture we have is mostly confined to the lower levels. The low level RH was calculated to be 73 percent, but the mid level RH is a whopping 12 percent. Boaters should remember to expect less clearance under fixed bridges. From synopsis, high pressure moving off the Carolina coastline will freshen breezes through the first half of the week.
1258 AM EST Sun Nov 17 2024 High pressure will provide dry and mild conditions through Sunday. Amplified flow pattern with a full latitude ridge over the area building east of the region overnight.

351 AM EST Sun Nov 17 2024 - Cloudy with chance showers today and tonight - Unsettled/Showery Week Ahead and Turning Cooler - Cloudy with chance showers today and tonight The morning begins with mostly high clouds as the region is in the dry slot ahead of the approaching cold front. An upper level low moving along the Canadian border will bring a short wave trough through the Great Lakes with a ribbon of moisture extending from Ontario across Michigan to the southwest through Illinois and Missouri. A Cold front will swing across the region today bringing a chance for showers.
423 AM CST Sun Nov 17 2024 Across the country today, there is a ridge of high pressure centered over the southeastern U. and a cut off low developing in the base of an upper-level trough to our west. A strong jet streak exiting the upper-level trough will leave the cut off low hanging back around South Texas heading into tomorrow before it lifts into the Great Lakes in advance of the next trough. This system's cold front will push east into our area as the low pulls away to the north. Forecast soundings show relatively weak instability and moist adiabatic lapse rates ahead of the cold front's arrival, though deep-layer wind shear will be increasing as well.
- Much colder for the latter half of the week with sub-freezing temperatures likely. Early morning water vapor imagery shows a large trough splitting into two smaller upper lows, one moving through the Northern Plains and Upper Midwest, and the the other digging into the Southwestern US and northwestern Mexico. Ahead of the trough, a stream of high- level moisture from the Pacific is noted, streaming into the Central and Eastern Plains. At the surface, a cold front is noted from southwestern IA, southwest into southwestern KS. The Southwestern trough will deepen and become negatively tilted as it moves into the Southern High Plains. This trough orientation will dramatically ramp up the low and mid-level moisture transport into the area.
(Today through Monday afternoon) Current satellite shows an upper low has moved into the Baja of Mexico. The low will slowly but steadily move east today across northern Mexico causing scattered showers and thunderstorms to develop this afternoon and evening in our CWA. The rainfall ends Monday with the arrival of the upper low. Rain ends with the low arriving, but winds will just be getting started on Monday as the mountains see strong winds beginning around midnight and lasting through the evening. Windy conditions develop in the lower elevations Monday morning after sunrise and diminish after sunset. Rain and clouds keep temperatures closer to normal today and cooler air moving in behind the departing low keeps temps cool Monday despite clearing skies.
Additionally, this lead speed max has advanced a weak cold front into the forecast area with its current position for near Salina through Pratt. The well-advertised midlevel trough will further advances toward the Plains today and tonight. Much stronger forcing for ascent arrives Monday morning into Monday afternoon as the trough axis takes on a negative tilt and tracks from west TX through eastern KS.
Precipitation has started ahead of a trough running SW/NE through our CWA. The highest QPF still favors our southeastern zones, where totals between 2-3 inches are likely.
We may see a few breaks in the clouds by afternoon, allowing temperatures to warm into the low to mid 70s.
Cold front moves through mid- week, bringing the next chance for rain, then colder, drier, and windier conditions by the end of work week.
At the surface, high pressure over the SE U. Some of this high cloudiness is also spilling over the SE upper ridge across portions of the local area. High temperatures today will range from the lower 60s in the NE mountains to the lower 70s across the S County Warning Area. Low temperatures tonight will range from the lower 40s in the NE to near 50 across the extreme SW.
620 AM EST Sun Nov 17 2024 High pressure will remain across the Middle and South Atlantic states through Monday, then move offshore Monday night. A strong cold front will move through the region mid-week. Otherwise, high pressure will extend down the eastern seaboard today.
644 AM EST Sun Nov 17 2024 High pressure will provide dry and mild conditions today. Otherwise, for today, a mid level ridge axis will move east while a mid level disturbance pushes into the western Great Lakes. This feature will be associated with a weak cold front. Filtered sunshine and southerly flow will result in high temperatures ranging from the upper 50s to the lower 60s. This will advance the weak cold front southeast into our northern forecast area. On Monday, the weak frontal boundary eventually dissipates while another mid level ridge briefly bulges northward into the middle Ohio Valley and central Great Lakes. It will be warm with highs in the lower to mid 60s.
A pleasant start to the morning as dew points have remained in the lower 60s giving us a little taste of Fall weather.
Strong to severe storms expected late this evening and Early this morning, an upper-level trough was located over Baja California. The upper trough should lift northeastward across west Texas by late tonight and become negatively tilted. Towards sunrise, a Pacific-based cold front should push a QLCS northeastward across west central Texas.
The next Pacific trough will move onshore tonight and associated cold front will sweep through during the day Monday. While regions like the eastern Magic Valley and potentially portions of the Lower Snake River Plain will see precipitation begin as rain or a rain/snow mix, precipitation type will transition to strictly snow areawide behind the front early Monday. A Winter Storm Warning has been issued for the Centennial Mountains/Island Park region beginning this evening through Monday evening for 6 inches to a foot of snow with localized higher totals along the highest mountain peaks.
- Westerly gales of 35 to 40 knots behind a cold front this afternoon and evening across the western half of the lake.
A dry low pressure system will continue to track eastward across northern Mexico today before exiting to the east on Monday.
