THE THERMOMETER CLIMBED TO A RECORD HIGH TEMPERATURE OF 101 AT ORF ON SATURDAYé─Â NO REAL RELIEF FROM THE HEAT UNTIL THE MIDDLE OF NEXT WEEK

Saturday was brutally hot across SE VA and NE NC as the high pressure ridge settled across the Mid-Atlantic Region. The combination of descending air which causes compression of the air, abundant sunshine, high humidity levels that don\\\'t allow much radiational cooling at night and light winds allowed temperatures to climb to record highs. Norfolké─˘s previous record of 98 was set way back in 1899. We broke that record by three degrees. Sundayé─˘s record of 102 will be a tough one to break.
We havené─˘t had any significant rainfall since May 28th and so we have to be concerned that our drought may be returning to NE NC and SE VA. This is not a forecast but based on the fact that these areas missed out on all that heavy rain that passed just to our north over the past two weeks and the upcoming weather pattern, ité─˘s not looking good for substantial rainfall. Now, officially, the drought conditions that began in 2007 have ended but not by much. It woné─˘t take that much dry weather to bring the drought right back with a vengeance. At this time of year, evaporation rates are at their highest, so moisture will be depleted from the soil very rapidly.

We lucked out this past Thursday and Friday as a back door cold front brought a marine layer into SE VA. Temperatures along the coast were much cooler than inland areas. Since ocean temperatures are still quite chilly, an onshore wind will bring relief to coastal areas. Sea breezes will develop so some coastal areas will be cooler during the afternoons. What about the chances of thunderstorms? Due to the upper-level ridge, the atmosphere will be capped for the most part, which basically means that thunderstorms will be hard to come by. However, weak boundaries caused by sea breezes could set off an isolated thundershower here and there. Trust me, if you get one, you are very lucky. Heat advisories are in effect so please be careful and try to stay cool and hydrated. When will the heat wave end? The current thinking is that a weak cool front will break the heat wave on Wednesday, but right now, there is some uncertainty to the extended outlook.
