LOCAL WEATHER OUTLOOK

Synopsis
After several weeks of warm, dry conditions, we finally look to be getting a short break from both, with cooler weather for the next few days and perhaps sometime the week after the coming one, and chances of some showers for the week ahead. However, it doesn't look to change the overall trend we've been seeing: we won't see much precipitation regardless, and temperatures will rocket back up into the 80s by the middle to end of the week. I expect our current categorization as abnormally dry (one category below drought) to continue through at least another week or two.

Day-By-Day Forecast

Tonight:
We'll see clusters of showers continue to move through, with moderate temperatures in the mid-40s. Showers will increase later tonight, and then slow to a trickle by sunrise.

Tomorrow: I expect all shower activity to be out of here by tomorrow morning as a front pushes off to our south. Skies will rapidly clear as the morning progresses, with a fairly nice, mild day on tap, with temperatures in the mid-60s and light winds.

Monday: Generally quiet weather will continue, with generally clear skies and temperatures again in the mid-60s. Enjoy it while it lasts...

Tuesday: A prelude to a warmer, more active rest of the week, southerly winds and fairly sunny skies will bring temperatures climbing into the low to mid 70s, along with a chance for some shower activity. Although that will remain scattered throughout the day with little actual rain, we could also see a chance for a few thunderstorms in the afternoon hours.

Wednesday: The active pattern continues, with temperatures rising higher, into the upper-70s, and a further chance for a few showers and storms.

Thursday: Although the official forecasts indicate merely partly sunny skies, I'm betting there will be a chance for a few showers and storms, as we'll see in previous days. Temperatures look to top out in the low-80s.

Friday: Similar again to previous days, Friday will feature temperatures again around 80 degrees, and we could see increased chances of some shower or storm activity as a cold front approaches. Models are currently differing on timing and placement of this front, which would affect when and how much precipitation and storminess we receive. Stay tuned.

Saturday: Depending on what models and forecasts one believes, it looks quite possible that the aforementioned front will already be past, leaving us with cooler temperatures in the low-70s and generally clear conditions. However, if the front is still on its way through, we would experience increased cloudiness, a definite chance for showers and perhaps storms in the afternoon, and temperatures rising into the mid to upper 70s. We'll have to wait and see what possibility emerges as the winner.

Extended: After the front passes, drier conditions look to prevail into the beginning of the week after this coming one. However, current long-range climatology is indicating the possibility of a major shift sometime during the week, with cooler than average temperatures and only mildly dry conditions through the end of that week. If this occurs, it would be the first real cold spell we've had in quite some time, so I'll keep my eye on it as the probabilities resolve themselves.

In other news, I will be attending the USA Science and Engineering Festival at the Walter E. Washington convention center in DC tomorrow, which runs from 10AM to 4PM. There are a number of really awesome weather exhibits there, including the famed Doppler On Wheels (DOW) radar trucks and a number of prominent scientists, including Dr. Joshua Wurman, with which I'll be filming stock footage and interviews on the importance of meteorology, science, and research in our modern world--so if you want to get in on all the coolness, come on down and check it out!

Thanks,
C. A. M. Gerlach
