Forecast: Much-Needed Rain for the Weekend

By Josh Larson

* UnitedCast: Rain? | Fargo's Record Flooding | D.C. Area Drought *

EXPRESS FORECAST

Today: Cloudy and drizzly. Mid-50s. | Tonight: Rain and t'storms. Near 50. | Tomorrow: Mostly cloudy; A.M. showers. Mid-60s. | A Look Ahead

FORECAST IN DETAIL

Yes, it's the weekend. Yes, most of it will be cloudy and parts of it showery -- but mainly tonight into tomorrow morning. Any rain that falls (some places may see up to 1"), will be beneficial in making up for our rainfall deficit. Tomorrow afternoon offers some real promise for outdoor activities, with just a slight chance of showers or thunderstorms, warmer temperatures and brightening skies.

Today (Saturday): The wet weather that pushed through the area last night will likely taper off during the early hours this morning. But clouds and drizzle will persist through much of the day. Another surge of moisture will bring showers back into the area late in the afternoon or during the evening hours. High temperatures, cooler than yesterday's, will struggle to break out of the mid-50s. Confidence: Medium

Tonight: Words of advice: bring an umbrella with you if you venture outside. A warm front pushing through the region will allow for continued overcast skies and periods of rain and perhaps some embedded thunderstorms. Overnight lows won't move much from today's afternoon highs, settling near 50. Confidence: Medium

Tomorrow (Sunday): The day starts off overcast and damp with scattered showers. However, after we get past mid-to-late morning, any precipitation should become spottier in nature and we'll have some afternoon warming and sunshine. Having said that, an isolated thunderstorm will remain a possibility (30% chance). Depending on how much sun we see, high temperatures may range anywhere from the mid-60s to near 70 along with southerly winds 10-15 mph. Confidence: Medium

Tomorrow Night: Just in time for the beginning of the work week -- seems to always work that way, no? -- plan on dry conditions Sunday night with partial clearing taking place and noticeably cooler overnight lows dropping to the mid-to-upper 30s in most areas. Confidence: Medium-High

A LOOK AHEAD

Monday morning will feel quite chilly with temperatures in the mid-to-upper 30s and a strong breeze; so, I'll second Camden's advice from yesterday's forecast: make sure you're adequately dressed as you head out for the day. Strong winds continue through much of the day -- gusting 20-30 mph -- but from a warm, westerly direction, which combined with mostly sunny skies should allow highs into the low 60s and overnight lows near 40. Confidence: Medium

The outlook for Tuesday calls for conditions closely echoing those we're likely to see on Monday, except less windy. That means a continuation of mostly sunny skies, dry conditions, and high temperatures within a few degrees of 60. Overnight lows will settle into the 40s area-wide. Confidence: Medium

@david

Most likely precip totals overnight into tomorrow morning will be between 0.5-1". Maybe a little more if showers/storms develop tomorrow afternoon

Thanks, Jason. Have a good weekend despite the rain.

Earlier data was indicating up to an inch and a quarter over the full storm sequence through tomorrow. It seems to be settling around 0.75" now.

We have a couple of rain opportunities next week around Wednesday and Friday/Saturday. These include nearby triple-point passages, something we weren't getting during the winter. However the large-scale cyclones next week won't be as intense as the one tomorrow morning.

It may be a good time to do a feature some time next week on triple-point cyclonic passages, as these are better precipitation producers than what we were having the past few months.

Incidentally, the Discovery Science Channel on Arlington Comcast 110 is doing a series of programs on storm-chasing and tornadoes in the Great Plains "Tornado Alley" today. They mentioned what triple-point systems in that vicinity can do [which is generally more severe than what they do around here!]

We just had a new portico built last week and this rain is a great test to see how waterproof it is...aside from that, this weather stinks! Give me some sunshine please.

NWS is mentioning a negatively-tilted trof and some pretty good wind shear aloft with this system, despite the relative stability and cool maritime layer at the surface. Could be a setup for some strong storms as cold front approaches. Under those conditions, the warm front doesn't have to move north of us and put us into the warm sector at the surface for us to get storms....the dynamics aloft take over.

That series on Discovery Science Channel, "Tornado Alley" is great. As far as todays weather, it keep's the forecasters on there toes when you have blizzards in one part of the country and tornadoes in another. http://www.kansasvortex.com/
