Aikyam-Lab/Synoptic-Bench huggingface dataset:
Cooler temperatures over the weekend as an off-cut low moves over the western U. bringing a slight relief from the warmer temperatures, with chances for some light precipitation in northern Nevada. Temperatures on a warming trend during the week with another, stronger low pressure trough late week with greater chances of precipitation. Today through Sunday Off-cut low pressure system moves across western U. bringing in cooler temperatures, however still expected to be warm for this time of year. Increasing cloud cover for much of the region as the low pressure brings in moisture, however chances for precipitation remain slim (below 25%) with a few spots in northern Nevada might see very light precipitation. Temperatures expected to be even cooler in the low 60s for northern Nevada, 60s to 70s for central Nevada.
Have a wonderful Saturday! (Today through Sunday) The cold front will pass through the area early this morning with limited showers possible as a lack of available moisture will not support much shower development.
646 AM EDT Sat Apr 12 2025 High pressure will usher in dry and slightly cool air for the weekend.
The mountains will see the highest chance of showers, with lower chances across eastern WA.
405 AM PDT Sat Apr 12 2025 Dry conditions are expected today as an area of low pressure moves east of the region. Northerly winds will be gusty along the coast and on ridgelines today. A trough currently moving through Northwest California triggered a few showers along the Trinity County northern and eastern borders overnight. Cloud cover this morning will quickly dissipate leaving mostly clear skies today as ridging begins to build into the region behind the departing trough.
924 AM EDT Sat Apr 12 2025 High pressure will lead to dry conditions and moderating temperatures through the weekend.
Currently have upper troughing across the Eastern CONUS with upper ridging moving out of the Rockies and into the Plains. At the surface, high pressure extends from the Great Lakes down into the Arklatex region with lee troughing strengthening over the High Plains. This will allow a prefrontal trough and then cold front to push through the forecast area Sun afternoon through Sun evening. Behind the cold front we are looking for highs on Mon to be back closer to seasonal normals as they top out in the mid and upper 60s with a slight warm-up anticipated for Tue. Low pressure will strengthen over the High Plains today which will ramp-up south winds across the area. Afternoon RH values will generally be in the 25 to 35% range with the lowest values generally west of I-135.
647 AM EDT Sat Apr 12 2025 High pressure will lead to dry conditions and moderating temperatures through the weekend.
- Breezy day today with warmer temperatures nearing 70 degrees.
Gust speeds will generally range between 20 and 30 mph, but 30 to 40 mph can be expected in the higher terrain. After the cold front moves through the region Saturday evening, post- frontal breezy northwesterly winds pick up across the southwestern Great Basin and spread southward into the Mojave Desert through the day on Sunday. Speeds will generally range between 15 and 25 mph, with higher gusts in the higher terrain.
Most locations should fall into the lower to mid 40s for Sunday morning. Reinforcing cold fronts will keep drier air locked in for much of the period.
Updated at 140 PM CDT Sat Apr 12 2025 - Hot and windy conditions this weekend before cold front arrives on Sunday.
Today, a thermal trough will result in moderate to strong north winds during the day with the strongest winds near and south of Port Orford.
(Through Sunday) A dry air mass will continue to filter over the area this afternoon and evening with high pressure settling in overnight and into Sunday. Dry conditions, clear skies, and calm winds overnight will lead to very favorable radiational cooling with lows dropping into the low to mid 40s across much of the area.
It will be breezier tomorrow as the surface pressure gradient tightens with high pressure shifting off to the east.
202 PM EDT Sat Apr 12 2025 An upper level low pressure system continues to spin over the area, bring cool and showery weather into tonight.
- Limited fire weather concerns in northeast Oklahoma on Sunday, with gusty southerly winds and well above normal temperatures ahead of a cold front.
204 PM CDT Sat Apr 12 2025 - Breezy & warmer weather is expected Sunday.
500mb analysis shows a mid level low pressure system across the northern Mid Atlantic states. A longwave trough extends down the east coast. At the surface, high pressure is centered across the Ohio Valley with a ridge extending southward into the Lower Mississippi River Valley. Ridging will eventually shift southward into the northern Gulf and western Sunday night. Temps should mostly remain above freezing in portions of north and west GA overnight. Isolated sheltered valleys could briefly flirt with freezing temps or just below right before sunrise. However, if temps end up even a little cooler than currently forecast, widespread frost is possible.
(This evening through Sunday night) Beautiful spring conditions continue with near normal temperatures in the low to mid 70s today as post-frontal drier air mixes in from the north.
/26/ (Saturday through Sunday) Calm winds and clear skies are allowing for regional temperatures to fall into the low 50's and upper 40's this morning. Given the return to marginal southerly winds, and dew point temperatures trending on the drier side for at least one more afternoon, elected to go about 2-3 deg F warmer for this afternoon when compared to NBM. Warming trend only continues further into Sunday as a strong southerly Gulf breeze advects not only warmer air to the region but also supports sustained 10-15 mph winds. As a result, expect for highs to easily reach the mid and upper 80's area wide as the upper ridge axis settles directly over the ArkLaTex Sunday afternoon.
Today: A weak trough passing through the state of Washington today will bring chilly low temperatures and showery precipitation to the forecast area. Additionally, the lift generated from this trough combined with 100-200 J/kg of SBCAPE values could bring some thunderstorms to northeast Washington and the Idaho Panhandle. This colder air and breezy wind will bring temperatures down, particularly low temperatures, which are expected to get below freezing tonight through most of the area.
At the surface, a post cold front air mass has brought cool, dry air. The clear skies have still allowed parts of the area to warm above 70 degrees this afternoon, but tomorrow should quickly bounce back to warmer than normal temperatures.

Windy conditions set in for the weekend as a weak trough moves through Arizona. High and mid-level clouds will increase through the day ahead of an elongated trough moving into the western US. Highs this afternoon are slightly cooler, they will remain near record levels.
(Tonight) High pressure continues to build over the TN Valley supporting clear conditions across the area. Despite this, lingering post frontal NW flow has continued to advect in a dry continental airmass keeping our temps comfortably limited to the low 60s this afternoon. With temps forecast to drop into the high 30s and low 40s, the combo of clear skies and calm winds will provide a favorable environment for frost formation.
1228 PM CDT Sat Apr 12 2025 Updated at 1135 AM CDT Sat Apr 12 2025 - Hot and windy conditions this weekend before cold front arrives on Sunday. A lee-side trough is currently developing in response to mid-level height falls associated with the approach of the upper jet maxima streaming towards the northern plains. This trough deepens and the resulting tightening of the pressure gradient leads to breezy south winds at 20 to 30 mph with gusts to 35 to 40 mph.
- Limited fire weather concerns in northeast Oklahoma on Sunday, with gusty southerly winds and well above normal temperatures ahead of a dry cold front. (Sunday through Saturday) An upper level trough will pass to the north Sunday with an associated surface front.
We are seeing much cooler and drier air behind the front today. Winds will be calming down overnight and combine that with the cooler air and clear skies will result in a great radiational cooling night. This means we will wake up cooler tomorrow morning with lows from the mid 40's to mid 50's. However temperatures will rebound quickly with highs in the low to mid 80's for most of us.
(This afternoon through Sunday) A drier and slightly cooler air mass enters South Florida behind a passing cold front today. Deep-layered high pressure will build back over the region through the rest of the weekend allowing for the dry pattern to persist through the short term period.

Dry and much warmer Sunday with building high pressure. Upper trough finally is slowly shifting eastward this afternoon. Upper low pressure will be moving off the mid Atlantic coast this evening and moving to the northeast. A cold night in store with lows dropping to near and below freezing except around Knoxville and Chattanooga. A warm front will move into IL by sunset Sunday. Temperatures will be much warmer and near average as winds become southwest during the day and there will be full sunshine with a few clouds moving in late.
(This evening through Sunday Night) As the upper level ridge axis moves overhead tomorrow, the remainder of the weekend will be defined by a marked increase in warming. Underneath the aforementioned ridging, the other defining feature tomorrow will be elevated wind speeds across our western zones, most particularly the east Texas hill country.
Windy conditions set in for the weekend as a weak trough moves through Arizona. High and mid-level clouds will increase through the day ahead of an elongated trough moving into the western US.
