Typical Summer Weather Starting to Dominate
Matt Ross @ 12:00 AM
Forecast
Today we will be partly sunny and breezy. Afternoon highs will be slightly above normal at 86-89 degrees. Humidity will be noticeable, but not oppressive. Tomorrow will be sunny and warm with diminishing winds and a high temp of around 88 degrees. Refer to Jason's forecast from yesterday for the rest of the week.

El Nino, Spanish for: The Nino
After spending much of the winter in weak La Nina conditions, sea surface temperatures have risen in the equatorial pacific. What does this mean? It is too early to predict with accuracy, but we could see El Nino conditions develop this fall into winter. Typically, but not always, weak to moderate El Nino conditions correlate with cold and snowy winters for the DC area, while stronger El Nino's tend to be much warmer without a lot of snow. Additionally, El Nino usually means a below average hurricane season, though I do not think this warming of the Pacific has occurred in time to significantly impact the current tropical season. The consensus of current statistical/dynamic models points to neutral/borderline El Nino conditions this upcoming winter, but the models did poorly last winter, and I have lukewarm confidence in them. I think more likely than not we see official El Nino conditions develop this fall or winter. How strong or weak could very well help tell the tale this winter.
Yesterday's storms were heaviest in the southern and eastern suburbs. National Airport set a daily precipitation record for June 19th as 1.99" fell, while most of the metro area received more modest amounts. Image courtesy of Weather Underground.
Link Between Hurricanes and Ozone
Probably like some of you, I thought this was another piece on how humans were responsible for 2005's record hurricane season. To my slight surprise, it is the result of a NASA sponsored study by two Florida State meteorologists which establishes a correlation between ozone levels and formation/movement of hurricanes. The study concludes that a measurement of ozone levels throughout the layers of the atmosphere can help pinpoint the location of the eye as well as future movement. Furthermore, it also suggests that ozone levels may be helpful in the early stages of storm formation when satellite imagery is not as useful.
