By Jason Samenow

* NatCast | UnitedCast | Weather Trivia | Photo Shoot *


Today: Chance of showers, especially in the afternoon. Low 70s. | Tonight: Chance of showers, especially early. Near 60. | Tomorrow: Rain likely. 60-65. | A Look Ahead


Last weekend this time, we were starting a 4-day sunny stretch with 80s to low 90s. This weekend we begin a 4-day rainy stretch with 60s to low 70s. It won't rain for this entire period -- with the best chance of some dry windows today and Tuesday. But, several inches of rain may fall -- with the bulk of it most likely Sunday and Monday.

Today (Saturday): Through early afternoon, it will likely be mostly dry save an isolated shower or two, particularly north and west of town. During the mid-to-late afternoon, showers will likely become more numerous (60% chance), with high temperatures in the low 70s. Rainfall potential through early this evening is about 0.1-0.2". Confidence: Medium-High

Tonight: Rain showers are likely (60% chance), especially in the early evening. A dry window may open up between mid-evening and pre-dawn, before showers resume towards morning (40% chance). Lows will be near 60. Confidence: High

Keep reading for the forecast into early next week...

Tomorrow (Sunday): Periods of rain are likely morning through evening, and the rain may be moderate at times. Rainfall amounts will probably be in the range of 0.5-75". The clouds and rain will hold down temperatures, with highs just 60-65. Confidence: Medium-High

Tomorrow Night: Intermittent rain should continue, with lows in the mid-50s. We may tack on another 0.5" of rain or so overnight. Confidence: Medium-High


Rain is likely once again on Monday and Monday night with highs in the low-to-mid-60s and overnight lows in the mid-50s. Confidence: Medium

By Tuesday, the front responsible for much of the rain may lift to the north (as a warm front), but some showers cannot be ruled out, especially early in the day and possibly again late. Highs should be in the low 70s. Confidence: Low-Medium

Updated: Saturday May 2 @ 10:45 p.m.

So how are we doing with our drought, both in the metro area and further west, where it's worse? I've seen a link to drought info posted here before, but I guess I didn't save it. If anybody could post it, I'd appreciate it.

I still don't understand how the number designations for storms work on the weather underground radar site. A few minutes ago the storm 'F6' changed to 'M6'. If the storm weakens, do they change the number and give it a new one? What are the criteria for a storm to be numbered? What makes a storm be un-numbered? Does anybody know?

We'll probably post a drought update early-to-mid next week, but here's a link to the drought monitor in the mean time:


I looked around and wasn't able to find any background on how wunderground numbers storms

If this is a "drought" how come we keep continually getting all this RAW CRUD in the forecast for days on end??? I'm sick and tired of this so-called "spring"! I figure we've had good weather about 15% of the time and weather that's too raw, too windy, or rainy the other 85%. And all this on top of a winter that I flunked for lack of good snow [the primary reason we got into this "drought" mess in the first place!]. Unfortunately the "rain dance" crowd keeps working its "magic".

It will sure be nice to get some DECENT weather for a change. If we get a couple of thunderstorms a week [not on dance nights, please] through the summer we should be in pretty good shape precipitation-wise.

Generally the upside of a drought is plenty of nice sunny weather. Thus I refuse to call this a real drought.

Thanks for the link, Jason! Couldn't find that site to save my life.

@Bombo47jea: I think it is fantastic that you flunked last winter and that you are, in essence, flunking this drought as well! I will happily join you on both counts.
