Storm Totals

The remnants of Tropical Storm Nicole brought incredible amounts of rain to the area, especially east of I-95 where some isolated spots received almost a foot of rainfall! I think it's safe to say that the drought has been temporarily busted.

La Nina, a cool ocean current off the west coast of South America, continues to strengthen. This could have a major impact on our winter weather. La Nina years in the past have typically brought mild and dry conditions during the winter. Don't be deceived - some of the coldest Arctic outbreaks have also occurred during La Nina years. It's definitely something to watch over the next few weeks!

Drought Update

Not only did we experience the hottest summer on record, but we haven't seen any substantial rain in over three months. Most of central Virginia is now in moderate drought. We desperately need a large storm system to bring us a good soaking!

June Officially The Hottest Ever!

The average temperature (highs and lows combined) for this past June was 81.1, which destroys the old record of 79.2 set in 1942. In addition, this ended up being the second driest June on record. Now you know why your lawn looks brown! We aren't the only ones dealing with the extraordinary heat. On the maps below, you can see that parts of North Carolina, South Carolina, Tennessee, Kentucky and Arkansas are also dealing with hot conditions.

Tropics Update - Tuesday 6/29

It's looking more and more likely that the center of Alex will make landfall along the northeast coast of Mexico on Wednesday night. From now until then, Alex should strengthen to at least a category one hurricane.

One computer forecast (GFS) keeps developing a non-tropical low in the northern Gulf. This is worth watching as well as it drifts slowly to the west. If it stays over water, it could start developing tropical characteristics. Otherwise, things should remain quiet for the next few days.

From One Extreme To Another

After experiencing the snowiest winter in nearly fifteen years, we could potentially break record highs this week. The Bermuda High will strengthen to our southeast and bring in some of the warmest air we have seen since last September!

Here are the two records that we could potentially break:
  • Tuesday...92 set in 1942
  • Wednesday...94 set in 1929

If you don't like the heat, you will have to be patient. It appears that this current weather pattern will break down by the end of the month. The North Atlantic Oscillation is a great index to spot long range trends. Whenever NAO is negative, temperatures will remain generally below normal, which explains our bitterly cold February. If NAO is positive, then temps will be above average, like what we've seen for the past couple weeks. The latest data continues to show NAO diving below zero by the end of this month, so get ready for a bumpy ride!

Winter Recap

Although we occasionally get a freak snowstorm in late March, I think it is safe to say that snow season is over in Richmond. It definitely was a winter to remember! We ended up with two and a half times as much snow than average. In fact most locations around the metro received three times as much as the average.

El Nino was a major factor for these impressive snow amounts. The southern stream was active all winter, providing plentiful moisture.

NAO was also a big player. It was negative for the majority of winter, which brought us cold air from the north. It was a perfect scenario for a big snow storms!
