.DISCUSSION...
Issued at 115 AM EDT Wed Mar 18 2026

Today is the least real chilly day of the week, though it will be a 
definite improvement over the last two days. An outside shot of some 
light drizzle or snowflakes as a weak disturbance passes overhead, 
low level dry air will be munching on the attempt at precipitation. 
The next week is characterized by a couple things, one is another 
notable warm up into the weekend, the other is several weak attempts 
at precipitation. Another weak wave will pass Thursday evening, 
another on Saturday, then the cold front next week. Each one 
mustering an attempt to produce a shower or two. 

Despite the number of disturbances, overall QPF is way under the 
weekly average rainfall. Mostly dry weather is the expectation, even 
if we score a few isolated showers on any one of the disturbances. 
To return to the temperature outlook, we're warming up the remainder 
of this week into a warm weekend, with the return of 80s over the 
southern valley Saturday and Sunday. The cold front next week won't 
be as sharp as the past two were, but is forecast to return us to 
milder late March vibes.
