Omega block pattern sets up late week and weekend…
Tuesday will see partly cloudy skies to start, then becoming mostly cloudy in the afternoon. Warm highs in the lower 80s today, then mostly cloudy skies maintain overnight. With a frontal boundary in the vicinity just off to our south, a few scattered showers may be possible later in the overnight period.
Wednesday may also see a few scattered showers, and mostly cloudy skies otherwise, then a weak and dry cold front will move though overnight. An omega block pattern will set up late in the week through the weekend and early next week, leading to dry and pleasant conditions in the low to mid 70s Friday through Monday, but also at least slightly below average temperatures for this time of year.
