Significant Snowfall for Washington Cascades and Northern Rocky Mountains

A cold front will linger for several days from the Pacific Northwest to portions of the northern Plains early this week. Cold temperatures and copious moisture will combine to produce several feet of snow into the mountain passes, with up to 4 feet of snow down to 4000 feet in the northern Rockies. Travel through mountain passes will be very difficult. Read More >

Light winds and abundant shallow moisture has led to fog development again tonight. Fog has become widespread and dense in places across the southern half of the forecast area. A Dense Fog Advisory has therefore been issued for areas south of I-20, and by our neighboring offices to the south until late morning Monday (areas shaded in grey). Conditions should improve around midday.
Clouds will be on the increase late tonight, and some patchy fog could develop across parts of the region after midnight. Otherwise, winds will be light and temperatures will generally fall into the 40s tonight.
It'll be a cloudy and wet Monday (for some) across North and Central TX. Afternoon high temperatures will climb into the 50s area-wide with increasing rain chances through the day. The best rain chances will be across Central and East TX. Mostly showers are expected, but a few embedded thunderstorms will also be possible.
There will be a significant increase in rain chances as an upper low moves northeast across West-Central Texas on Tuesday. The best rain chances will occur across the southeastern half of the region where rain is almost a guarantee, with slightly lower chances farther northwest. Severe weather is unlikely, though a few storms may become strong and produce small hail and frequent lightning. Precipitation will move east of the region late Tuesday night.
Forecast models are showing cold air arriving next week around December 22nd and 23rd (on average). What we do not know for sure yet is exactly when the cold air arrives, how cold temperatures will be, and if there will be any precipitation and what kind. We will be providing updates when/as we acquire better confidence in the late week forecast.

We will have a little bit of everything: rain chances Monday and Tuesday, dry Wednesday and Thursday, and a strong cold front on track for Thursday night and into the holiday weekend. Stay tuned for updates and further details as new data becomes available.
