A strong Canadian ridge of high pressure will dominate over the next several days while ushering in the coldest overnight/morning temperatures so far this fall. There should be enough of a wind tonight to keep the atmosphere mixed enough to keep temperatures at or above the upper 30s by morning. But with calm winds and crystal clear skies I would expect a good chance of our first frost of the season by Wednesday morning (especially along on north of the I-10 corridor) with lows dropping into the mid-30s. So you may want to protect the tender vegetation for tonight and most certainly tomorrow night. Highs will stay in the low-mid 60s tomorrow but should return to near 70 for Wednesday afternoon. Unabated sunshine will likely last through at least Thursday with moderating temperatures and fair to partly cloudy skies for Friday into the weekend. Highs will be back into the upper 70s for Friday and could be in the lower 80s this weekend. No major weather systems are foreseen through at least mid-next week so it looks to stay quite dry.
