The coldest airmass of the fall moves in for Tuesday, with blustery NW winds gusting to 25mph and temperatures
struggling to reach 40F. Very good mixing making for very GOOD air quality. For Wednesday, NW flow continues,
but drops off. Even with sunshine, highs top out only near 40F, with GOOD air quality continuing. Temperatures
jump up a bit on Thursday into the low 50s, as high pressure builds aloft. Surface winds light NW. With high
pressure overhead and limited mixing, fine particles may build to MODERATE, especially around Providence.
