Warm and Dry Over the Next 7-10 Days
Josh Larson @ 2:55 PM
Say goodbye to the past week's worth of delightful, below-normal temperatures, since the next week to ten days looks to feature a return to warmer than normal conditions along with the continued absence of significant rain. Luckily, though, average temperatures at this time of the year are much more comfortable than a month ago, so don't fret too much.
Partly cloudy. We'll look for very similar conditions today as yesterday. Expect some morning fog to give way to partly cloudy skies, with afternoon highs in the mid-to-upper 70s. Partly cloudy and milder overnight, with lows from 60-65.
Milder. Look for a blend of clouds and sun on Friday, with a noticeable uptick in both temperatures and humidity levels. Afternoon highs will range from the low to mid 80s with partly cloudy conditions overnight yielding mild low temperatures in the mid to upper 60s.
Mostly sunny & warm. Look for a blend of clouds and sun on Saturday with very warm temperatures in the upper 80s -- to perhaps 90 -- in most areas. It will be mild during the overnight hours, with lows from 65-70. Sunday looks to feature mostly sunny and possibly breezy conditions with slightly cooler -- but still warm -- high temperatures in the low to mid 80s. A notch cooler Sunday night, with lows in the low to mid 60s.
The main weather story over the next week or so will be the continuation of very dry conditions, with little chance for measurable rain during the period, along with a noticeable warm up in temperatures by this weekend into the start of next week. In fact, day time highs by Saturday may be some 15 degrees warmer than temperatures last week. What's the reason? An abnormally strong (amplified) ridge of high pressure will move into the eastern US by this weekend. Temperatures look to remain above average until at least the middle of next week, by which time a cold front might bring cooler temperatures for the end of the week.

An area of disturbed weather west of Florida is the only real tropical excitement in the Atlantic basin at this time. It is possible that this area of storminess may intensify into a tropical depression (or, perhaps, weak tropical storm) before it makes landfall sometime early this weekend somewhere between western Louisiana and the Florida panhandle.
Next week's forecast
Forecast highs/lows: 82/64 (normal = 78/58)
Forecast precip: Much below-normal
With strong high pressure firmly in control during the first half of next week, we're likely to see mostly sunny skies, warm (above-normal) temperatures and little or no chance of rain. For Monday and Tuesday, expect mostly sunny skies with highs in the mid 80s and moderate humidity levels; we'll have mild overnight lows from the mid to upper 60s both nights. The forecast for Wednesday calls for somewhat of an increase in cloudiness, with a slight chance of a shower and highs in the low 80s and overnight lows primarily in the mid 60s. From this far vantage point, Thursday and Friday look to feature mostly sunny skies and slightly cooler temperatures in the upper 70s to near 80 and overnight lows mostly in the low 60s.
