Prognosis on track; Mainly dry in the afternoon then ice/snow tonight

On February 14, 2025By Littum

The forecast works surprisingly well this morning. There was a short afraid of about 1 p.m. 05:30, when Portland Radar went offline for about 4 hours. It’s back online now … Whew! It looked like this during that time and you probably noticed your app showed little or no snow overhead

We have had enough snow for most untreated ways to be snow -covered at noon with strong winds. It looks like PDX had a highest gust of gusts of 51 or 52 km / h (rounding problem) at. 8:01. It is the strongest gust of gusts of all winter. Windchill Temp was about 12 ° at the time … Brrr! Here’s the view of HWY 26 near Sylvan right now. Incidentally, this also means Portland stays alive winter stripe with measurable snow. This is the 10th winter in a row.

We predict 1-3 ″ as this first band of snow went through and a total of 2-4 ″ ends Friday morning. So this morning is a kind of “first act”.

The break

But now it is on to the “break” that models correctly predict. Snow ends mainly in the metro at noon, then all quietly through sunset. Expect stains to melt on some roads as the rising solar angle in February makes the rush with temperatures hovering near freezing.

AKT 2

Rising “mixed showers” of freezing rain, ice pellets, snow arrive in the evening. This is because a warm layer of air moves in overhead when a surface -low pressure center moves on land. Snowflake that falls down, melts and then falls into the freedom of air over us. They are either frozen as small piles of ice (ice pellets) or fall like liquid rain and form an icy glaze on contact (freezing rain).

These showers continue/in the whole night, not much, but enough to freeze any roads that melted during the day. Gusty East Wind will continue tonight. All untreated roads west of cascades (except coastline) must turn a lot of ice.

The final

Defeating changes back to snow before sunrise when air gets colder over the head again. Temperatures hovers around freezing or just below the morning commuting (or whatever is left of it). I expect ½-2 ″ extra snow falling, ending at. 10 Friday. This means that things will largely be closed the first part of tomorrow. The good news? The east wind is gone at sunrise! This event should be over before noon.

Temperatures rise well to freeze the rest of Friday; Don’t Cancel these Dinner Plans Friday night yet! Many roads will be completely fine in the middle of the end of the afternoon (provided we only get 2 ″ or less in the morning). Melted is on … you can enjoy your long weekend.

Time is short for me today as I am in the air again around 10 pm. 14.00. You can catch me there.

Hopefully I get another quick blog post tonight between shows.
