PM Update: Friday looks mostly fine

Slight chance of late day shower Fri.

5:30 p.m. update - meteor shower tonight:With little moonlight (we’re three days past new moon) and clear skies, conditions overnight may well be ideal for viewing the “bits and pieces of the famous Halley’s Comet” according to Space.com The peak will be early in the morning between 2 and 3 a.m. when up to 30 to 60 meteors per hour may charge through the night sky.

From 4:10 p.m.: Cools winds from the northwest, gusting to 25-30 mph at times this afternoon, have taken away from an otherwise spectacularly sunny Thursday. High temperatures have generally reached the upper 60s. We cool back down into the 40s tonight before temperatures take a ride up into the low 70s Friday.

Through Tonight: Skies are clear and winds diminish. Those two factors help temperatures fall off at least 20 degrees from afternoon highs. Lows in the early morning range from near 40 in the colder suburbs to the upper 40s downtown.

Tomorrow (Friday): The day begins on the sunny side but becomes partly sunny as high and mid-level clouds stream in ahead of a weak front. The day time hours are mainly dry and comfortable, with highs in the low 70s. But by late afternoon or evening, there’s a 30% chance of a shower. Winds are from the south at 10 to 15 mph.
