Aikyam-Lab/Synoptic-Bench huggingface dataset:
- Cooler and drier conditions are expected through the work week, with a substantial cooldown coming for the second half of the week behind a reinforcing cold front. - Hazardous marine conditions is forecast to return midweek after the passage of a reinforcing cold front late Tuesday. (Tonight through Tuesday night) With the cold front to our east, most of the showers and storms have exited the area. There is a very thin line of showers that is trailing on the edge of the cold front but that should lose whatever little steam it has left pretty soon.
- A strong cold front will bring well below average temperatures mid-week. Any fog should burn off my mid Monday morning and weak ridging will continue during the day.
A developing upper ridge will help temperatures warm slightly today but remain cool. This ridge will determine general conditions across the area for most of the week. East side areas look to generally be in the low to mid 60s, while lower elevation areas in Modoc and eastern Siskiyou counties could also approach the high 60s.
647 AM CDT Mon Oct 27 2025 - Temperatures to skew warmer than normal through Tuesday. - Strong cold front pushes through the region Tuesday evening / night, bringing much cooler temperatures and gusty winds in its wake.
432 AM CDT Mon Oct 27 2025 -Cool and damp weather continue today before another round of rain arrives tonight/Tuesday with a cold front. -Frost will be possible later in the week as much cooler air moves in. This morning, the upper low that has caused cloudy and wet weather around the region continues to slowly move east, away from the area. The next system to impact the area is an amplified mid-level trough, approaching from the northwest today. An associated cold front will bring rain, windy conditions and cooler temperatures tomorrow and into midweek. Mid-level ascent behind the cold front will allow a batch of rain to develop and move from west to east across the forecast area late this evening and tonight.
424 AM PDT Mon Oct 27 2025 VFR conditions are anticipated across all terminals as high pressure extends from offshore southern Oregon into northeast Oregon, producing westerly surface flow.
- Rain returns to the area on Tuesday ahead of a cold front with gusty winds and cooler temperatures behind it. Near calm winds resulting from high pressure firmly established across the region along with increased low-level moisture from recent rainfall will allow for the potential for overnight fog across much of the ArkLaTex. High temperatures are forecast to range from the mid 60s across south Arkansas, where ceilings may be slower to break and the airmass is slightly cooler, to the lower 80s across Deep East Texas.
-A cold front will usher in relatively cooler temperatures with breezy to possibly windy weather between the middle and the end of this week. Model guidance trends continue to depict a weak lower level setup, but a deepening trough near the middle and end of the week may lead to a cold front pushing through. MOS guidance reflects dew points in the lower 60s that are typically associated with an airmass that is simply more comfortable. From synopsis, high pressure situated along the Eastern Seaboard will lift northeast into Canada.
637 AM CDT Mon Oct 27 2025 - Rain is forecast for this morning through Tuesday night, with the highest chances (55-75 percent) Monday into Monday night. This low pressure is forecast to move to northeast through the morning and early afternoon, which will continue to bring rain to central SD, with higher rainfall amount more specifically in north central SD. With the help of some cold air advection pushing on the stationary front, the front will transition into a cold front and start moving east this afternoon through central SD, and northeastern SD and west central MN tonight into Tuesday.
The timing of the rain remains somewhat uncertain as a complex area of low pressure develops to our south and west and moves into the area. A few areas of mist and drizzle have fallen from these clouds, mostly across the higher terrain, and this will continue to be possible for the rest of the night. High pressure will remain centered across western Quebec and eastern Ontario, while an area of low pressure will develop and progress slowly across the Mid- Atlantic. Summits will stay below freezing through today and continued clouds should keep most of the snow around, but as the inversion begins to develop on Tuesday, temperatures should gradually rise above freezing.
Near normal temperatures are expected until much cooler air settles in for the second half of the workweek.
- Showers will become more widespread late this afternoon into tonight as a cold front crosses the area.
626 AM CDT Mon Oct 27 2025 - Widespread light rain showers are likely late today through Tuesday mainly in northern Minnesota, with the highest rainfall amounts in the Brainerd Lakes area. High pressure over northeast Ontario and deepening low pressure over the Southern Canadian High Plains creates a deepening trough over the US Northern Plains. The trough pushes into northeast Minnesota and Tuesday afternoon, along with a decaying stationary frontal boundary.
640 AM CDT Mon Oct 27 2025 Updated at 626 AM CDT Mon Oct 27 2025 - Showers will gradually taper off into Monday with continued cool temperatures in the lower 60s.
- Strong frontal passage expected Tuesday night, bringing much cooler temperatures, gusty winds, and elevated to critical fire weather conditions in its wake. Attention then turns to a strong upper trough digging south through the central CONUS on Tuesday, sending a strong cold front through Texas Tuesday evening into Tuesday night.
-A cold front will usher in relatively cooler temperatures with breezy to possibly windy weather for the middle to the end of the work week. From synopsis, high pressure situated along the Eastern Seaboard will lift northeast into Canada.
Following a cold front passing through northern UT, high elevation snowfall will continue across the majority of the Wasatch Mountains through this afternoon. Following this activity, ridging builds into the forecast area with a warm-up expected throughout the week with calm weather. Key Messages: * Mountain snow will persist through this afternoon across the majority of northern UT following the passage of a cold front. * A ridge of high pressure builds in Tuesday creating a warming trend across UT and southwest WY.
High pressure is building in to the area, bringing dry weather for much of the week. A chilly night is forecast tonight, with potentially freezing temperatures in Trinity County.
Updated at 200 PM CDT Mon Oct 27 2025 - A cold front comes sweeping in Tuesday morning, yielding breezy winds Tuesday and below-normal temperatures through mid-week.
We're starting with mostly clear skies this morning on the backside of the upper trough.

232 PM CDT Mon Oct 27 2025 - Greatest rain chances shift to far northeast South Dakota and west central Minnesota from this afternoon through Tuesday night, with the highest chances (50-80 percent) tonight and (30-65 percent) Tuesday. Watching a line of CU developing over central/north central South Dakota along a cold frontal boundary, where temperatures have warmed into the mid 50s to low 60s. Winds out ahead of a cold front, draped across Corson/Dewey Counties, are out of the south at 15 to 30 mph with gusts occasionally up to 40 mph. The cold front/showers will continue to move/develop eastward into northeast South Dakota and west central Minnesota this evening.
WEATHER PATTERN OVERVIEW: Stacked low over the Canadian prairies will be slow to move eastward with a blocking high over eastern Canada. Through midweek the trough extending south across the plains will stretch and under cut the Canadian high and allow high pressure to build into the western states.
110 PM CDT Mon Oct 27 2025 - Low pressure system exiting the region, will bring isolated showers to the Golden Triangle area today. These conditions were being maintained by a closed low noted spinning over western Tennessee and western Kentucky. Clouds will gradually decrease form the southwest this afternoon as the closed low shifts farther to the northeast. The sunshine this afternoon will help temperatures top out near normal but much of the northeast half of the CWA will remain cooler than normal today.
