September 21st, 2007 Forecast

If you can deal with a few clouds this evening and a few clouds tomorrow, you should be fine. Really, that is the weather story for the next few days as we continue a stretch of dry, dry weather here in the Delaware Valley.

Expect the high clouds that places from Philadelphia on south are seeing to hang out for the evening. A weak trough is moving through the region and should be able to nudge enough of the clouds out of the way to bring us a mostly sunny day on Friday. A few fair weather clouds are possible in the afternoon but given the dry conditions and lack of moisture in the atmosphere those clouds will be few and far between.

Tonight's lows will be in the 50's N & W to 60's City and the Shore. Tomorrow's highs will be in the 80's for everyone but the Shore, which will stay in the upper 70's. Saturday will be a couple of degrees warmer as we get a more pronounced southwest wind and parts of Delaware could sniff 90 Saturday afternoon while much of the region is 'only' in the mid and upper 80's.

The next chance of any decent rain will be on Tuesday night and Wednesday as a frontal boundary moves east. This may have some moisture associated with current Hurricane Ivo in the Pacific as well as some of the moisture from the mess of storms in the Gulf of Mexico. Of course, it being a week out it could still end up being a dry front but I do think with the Gulf of Mexico system involved we could see a decent chance of some rain from this front.

Climate Costs: The World Meteorological Organization called for a multibillion dollar boost in weather forecasting in order to help combat climate change, with 30% of a developing nation's GDP (sounds familiar in developed nations as well) tied to what happens in the weather.

La Nina Flexes La Muscle: The developing La Nina is being blamed on floods in Africa.
