Forecast: Sunsational!

By Matt Rogers

Sunshine and mild weather return to salvage weekend

* Hurricane Tracking Center | Outside Now?: Weather Wall *


Today: Becoming sunny, warmer. 78-83. Tonight: Mostly clear. 58-63. | Tomorrow: More sunshine and warm. 81-86. | A Look Ahead | Get Express Forecast by E-mail


Sunshine-laden high pressure from the Midwest will finally succeed in pushing our pesky low pressure out of the area. The result will be much nicer weather for the last day of our weekend. While some clouds are possible this morning, the sun should dominate the day as temperatures move back into the 80s (the last time we were in the 80s for highs was exactly one week ago). The nice weather should persist for Monday and Tuesday, but cool/wet weather returns by mid-week.

Today (Sunday): Morning clouds possible, but mostly sunny skies for most of the day with light winds from the northwest helping to dry the area out. Look for highs to break into the low-to-mid 80s throughout the region. Confidence: High

Tonight: Mostly clear skies and comfortable to cool temperatures (ie. keep-windows-open-weather) with lows ranging from the upper 50s to the low 60s. Light winds will continue to blow from the northwest direction. Confidence: High

Keep reading for the forecast through the coming workweek...

Tomorrow (Monday): The return to a five-day work-week (boo) is at least a pleasant weather one with 80s and more sunshine than clouds. Winds will continue to be light from the northwest as slow-moving Midwest high pressure edges closer. Confidence: High

Tomorrow Night: Pleasant conditions prevail with mostly clear skies and lows again in the upper 50s to low 60s. Confidence: High


Tuesday continues the dry, sunny, and warm streak with high temperatures possibly lifting a little higher into a range through the middle to maybe upper 80s. Some afternoon clouds are possible as a cool front approaches the area. Confidence: Medium-High

Wednesday through Friday will feature a pair of weather-makers: a strong, cool high pressure from Canada and a large-scale disturbance from the Gulf of Mexico. They are threatening to join forces to create another cool, cloudy, easterly flow pattern with plenty of showers and maybe thunderstorms through this middle-to-end of the week. High temperatures will be in the 70s with lows in the 60s mostly, but I would not be surprised to sneak in even cooler conditions depending on the tracking of these two features. Confidence: Medium

The early take on our next weekend could be a repeat of this weekend with a cooler, damp look to Saturday and then a warmer, sunnier Sunday again. Confidence is very low at this early stage though.

Nice puffy cumulus clouds, fair weather this morning. 74 degrees.

Will we hit our last 90-degree day of the season this week? Have we done so already? Climatologically, we have seen 90 degrees as late as Oct. 11.

Good question Bombo. My feeling is that 90-degree days are in the rear-view mirror now, but if we do manage to get one between now and October, odds are better that it will be a dry air 90-degree reading (not humid). In general, the pattern over North America seems to be transitioning into autumn quite quickly. I remember in 2005, the summer went deep into September. Not this year.

With dewpoints above 60 degrees, I was expecting conditions to feel worse than they do! At least we're hovering around 80 today. And the breeze is blowing. A really nice September day... regarding Autumn approaching.. I hope it takes its time. I dont want 50s just yet ;0)

I'm shocked, shocked that CWG would present only one point of view here. With all of the "data" being displayed by CWG, there is no horoscope or almanac forecast. And where is the cosmic ray flux and sunspot count? Why are you silencing dissent?

How can you justify scaring the public with such an irresponsible forecast of sudden warming into the 80s? It hasn't warmed in the last 10 days. Here I've followed the example of BS [blog "scientist"] Matt Rogers: "I take this all very seriously and went to all [three local] data sets to accumulate the data myself. MS Excel tells me the slope is negative! You can see that here: all [three]sources " Clearly, the high temperature will be below 0 by November. Why are you hiding this information?

H20 (water vapor): "The argument that the air we currently exhale is a bona fide pollutant due to potential impacts on climate change flummoxes me. [H20] is also plant food." Why, then, do you have such obsession with clouds, showers, and thunderstorms, since they're a perfectly natural processes? Water vapor is less than 1% of the atmosphere! Rain has started and stopped from natural forces for billions of years, long before anyone ever thought of a so-called "model". Why would anyone believe that we can now "forecast" the "future"? There were at least 6 separate and distinct clouds over my house at 10:30 this morning. Did any of your "models" predict their size and location?

I'm expecting the "peer-review purists" will arrive as they always do every evening. "I have definitely seen this line of debate frequently: it is not a fact unless it has been cut-and-pasted from a peer-reviewed journal. " Well, don't try to fool me with any of that elitist sciencey stuff.

@Capital Climate, what is up with all the hatin'?

Just following the twists of Matt's global warming "logic". Apparently he has no response.

CapitalClimate: I guess my response is just to smile as one would do with any comedian. Thanks for your creative word-smithing!

So you agree that your climate position is, in fact, comedy. Why wasn't it labeled as humor?
