EXPRESS FORECAST

Today: Mostly sunny and seasonable. 44-48 | Tonight: Increasing clouds. Low 30-34. | Tomorrow: Chance of light rain. 41-45 | A Look Ahead

FORECAST IN DETAIL

The weekend begins with quite a nice early January day...with sunshine and moderate temperatures. Sunday won't be as pleasant with overcast skies and some patchy light rain. Waiting for more winter-like weather? We may get a quick taste of it Tuesday, but as with most storms this season, sufficiently cold air doesn't appear like it will stick around long enough for accumulating snow.

Today (Saturday): High pressure cruises through the region today giving us sunshine and temperatures right around average. Most locations should max out in the mid- 40s, but don't be surprised if a few spots make a run towards 50, especially in the southern suburbs. Confidence: Medium-High

Tonight: Clouds increase as the next weather system approaches from the west. There's a 30% chance of rain towards dawn. A few spots well north and west of town (northern Montgomery and western Loudoun counties and to the north and west) could see a brief period of ice (20% chance). Lows will range from the upper 20s in those outlying areas to 32 to 35 (close-in suburbs to city). Confidence: Medium

Keep reading for the forecast into early next week.

Tomorrow (Sunday): Patchy and intermittent (any freezing rain well north and west will quickly change to rain) light rain is possible (50% chance) -- mainly from late morning to mid-afternoon. Having said that, the timing of the rain is a little uncertain, and significant chunks of the day may be dry. Confidence is higher it will be cloudy most of the day, holding high temperatures in the low-to-mid 40s. Confidence: Medium

Tomorrow Night: Mostly cloudy skies should slowly clear towards morning after a passing cold front pushes towards the Eastern shore. Low temperatures will drop from 29-34 (suburbs-city). Confidence: Medium-High

A LOOK AHEAD

Cool high pressure building into the region means a dry, sunny start to the work week. Highs Monday should reach the mid- to upper 40s with a bit of a breeze. Monday night will be clear early, with high clouds moving in late. It will be seasonably cold, with lows 25-30 (suburbs-city). Confidence: Medium-High

An area of low pressure developing to the southwest brings precipitation back to the region Tuesday. It may briefly begin as snow or a wintry mix during the morning, but warm air advancing into the region from the south will very likely change the precipitation to rain before much, if anything, in the way of accumulation. Highs should be from 35-40. Confidence: Low-Medium

I think global warming should be viewed with the idea of heat-enthalpy-redistribution, rather than a warming occurring at every latitude. This would be more consistent and much more likely. Warmer polar temperatures are caused by heat migrating to the poles. The heat does that because increased certainty in the polarity of the planet results in a reduction of the role of randomness in weather patterns. That randomness had prevented heat flows from becoming coordinated with spin in atmospheric patterns. Spin appears in cyclonic storms. Randomness is reduced when electric field coupling with the exterior galaxies, stars, and planets comes from specific observations, and even two way communications with wide-band, high data rate low entropy channels with planets such as Mars, Jupiter, Saturn and beyond.
These data streams cut through the interplanetary dust and cause immediate registration of the electric field influence of each planet with the other, whereas prior to the low entropy data channels, the two planets interacted only gravitationally.

Just this year, snow in this temperate latitude melted very slowly, and lay around in piles for days after the main fall of snow melted.
