from last night…

With current average high temperatures for this week running in the low to mid 50’s, today’s cold temperatures made it difficult to remember that [astronomical] Spring starts in another week.

This week, we’ll have a few more reminders that we’re still in winter.

Tomorrow, Tuesday, may have a brief period of light snow showers/flurries in the morning, especially northwest of the city. Indeed, the model blend shows a greater than 50% chance of light snow showers far northwest of the city before a change to light rain.

This afternoon’s RAP model shows very light snow showers moving through late morning.  No accumulation expected.  (The air has been so dry, it’s unclear how much of this may evaporate before reaching the ground.)

Tonight’s 00z HRRR model, just available, has a similar forecast.

The total amount of precipitation on Tuesday will be very light, possibly not enough to reduce the wildfire danger.

A more significant rain maker is expected on Thursday, as the low pressure system that caused the blizzard in Colorado moves eastward with possible secondary low pressure development near the coast.

The GFS model suggests enough secondary development and cold air to allow a changeover to light snow showers early Friday morning. Right now, no accumulation expected.
