Sunday Update: The Front Range Forecast: Winds drop and an eclipse

In Brief:

Winds drop, temperatures rise and clear skies for the eclipse.

Sunday update.

Strong winds and high fire danger continues for a few more hours. We take a few days to return to the 70's (Figure 1 update) while rain chances remain very low.

For the eclipse, the sun will be blocked to about 70% at 12:41pm.  The first moment of partial eclipse will arrive at 11:24am and the partial eclipse will end at 1:54pm.  At NO time will this eclipse be safe to view with the naked eye from Colorado. Skies will be mostly clear at the time of the eclipse (red line in Figure 1 update).

  You must have approved sun viewing glasses to view this directly (there are still some that will arrive over night and same day from Amazon (not a sponsor).  You can also view it by putting a small hole in an index card and projecting the image on another card below, or on a table surface (for example).  Be safe and enjoy!

End Sunday update.

The Forecast Discussion:

Friday showers move off to the east as a warm weekend sets up (Figure 1).  Another somewhat-cut-off low drifts by Sunday PM and Monday giving us a possible quarter inch of rain.  Nighttime snow showers are possible, but I-25 cities may only see snow in the air or a coating on the ground overnight.

The Sunday/Monday showers come in with a low pressure system and cool front (Figure 2). There will also be a chance of thunder with this system, but nothing severe (Figure 3).

Easter Sunrise Forecast:

Sunrise will be at 6:34am with temperatures around 36F, 20% cloud cover, and winds from the easte around 4mph.  It should be a pretty good sunrise service wherever you go along I-25.

The Long Range Forecast:

A warm-up kicks in Tuesday with possible 70's later in the week (Figure 1).  For Longmont, the next 5 days may see up to a quarter inch of water fall (Figure 4), but snowfall should remain in the Foothills and nearby mountains (Figure 5).
