What a string of beautiful days to build up to the official arrival of spring this Saturday! The only question is whether it will last through Sunday. I'm betting it can. Computer models are slowing down the progress of a cold front so that Sunday should still be salvaged, though not without some increasing winds and clouds, and a chance of rain late in the day or at night. Monday reminds us that spring is in its infancy with a cooler and blustery day, and possibly some rain.

Today (Thursday): Plenty of sunshine and only light winds from the northwest will make this the best day of the year so far. Highs will likely reach the 70 mark across much of the region. There could be a light veil of high clouds from a storm passing well southeast of the area. Confidence: High

Tonight: We'll see temperatures drop fairly quickly in the evening with nearly calm winds and clear skies. Look for readings to bottom out in the mid-30s (colder suburbs) to lower 40s (downtown). Confidence: High

Keep reading for the forecast through Monday....

Tomorrow (Friday): A virtual carbon copy of Thursday with lots of sunshine and highs reaching the delightful lower 70s in most areas. There could be some thin high clouds early in the day but perfectly blue skies should be in place by afternoon as the storm off the Southeast coast progresses well out to sea. Confidence: High

Tomorrow Night: Another night of calm winds and clear skies will allow temperatures to drop off steadily once again. Lows should be mainly in the low-to-mid 40s. Confidence: High


Saturday is likely to be even warmer. Highs should be in the low-to-mid 70s with mostly sunny skies all day long. Winds will remain light, making it a great day for whatever outdoor activities you enjoy (unless it involves snow). Confidence: High

Sunday starts even milder than Saturday with morning lows only down to the upper 40s. We'll probably have increasing high and then mid-level clouds, but highs should still manage the upper 60s to low 70s. By afternoon, winds may pick up to around 10-15 mph from the south ahead of an approaching cold front. Showers and thunderstorms could reach the area by late afternoon, but more likely not until the middle of Sunday night. Confidence: Medium

Monday will remind us that we don't live in San Diego! Highs may still approach or reach around 60, but could feel cooler than that considering the potential for some rain, thunderstorms and gusty breezes. Confidence: Low-Medium

Been a while since we've used the stamp! yes indeed. The pollen is ruining it for me tho. ugh. :)

Red maple is going crazy, with some silver maple and elm still in bloom. Pollen effect is much greater now than on Monday when it was "washed out" by rain.

Noon weathercasts on Channel 9 will be knocked out by NCAA March Madness today and tomorrow, as well as next Thursday and Friday. Please turn to Channel 7 for the full broadcast.

On Saturday the waxing crescent Moon will be very close to the Pleaides in the hour or two after sunset. [Later at night the Moon and Pleaides will set.] Weather should still be clear.

Expect some thunderstorm action Sunday evening or overnight as the cold front passes. This will be our first big convective outbreak of Spring 2010.
