Severe Potential Friday & Saturday
FRIDAY
Let's first tackle Friday's forecast. The front will reside out west, so we will see a strong SW wind which will bring heat and humidity back to the area.
This will make the atmosphere slightly unstable.
Jet stream winds will be strong enough to provide some speed shear (winds increasing with height). In addition, with surface winds from the southwest and jet stream winds from the west, there is some directional shear (twist) in the atmosphere.
With the front so far away on Friday, thunderstorms will remain very isolated, so we are not expecting widespread severe weather.
SATURDAY
The front will settle into the area on Saturday.
The atmosphere will also become unstable.
Just like on Friday, jet stream winds will be moderately strong from the west, so we will have both speed and directional shear.
Taking this all into account, the threat for severe storms looks higher for Saturday. The key to the forecast is sunshine. If we are stuck in thick cloud cover, then the severe potential will drop.
It's something we are watching very closely and will have more updates to come!

Check River Levels & Swim Safe (And Legal!)
So before you go for a refreshing dip in any river in Virginia this Summer, stay safe (and legal) by checking the river levels before you go. Here is a link to river level measurement sites across the Commonwealth: http://water.usgs.gov/waterwatch/?m=real&r=va&w=map
Mouse over any of the dots, and you'll see more information about that location on a river. Click on the dot for more detailed information, including graphs of water level rises and falls recently. Stay safe and check the levels before you swim!

First the Cold, then the Heat
Flirting With Summer This Weekend!
April 24: 94 (1925)
April 25: 96 (1925)
April 26: 96 (1960)
April 27: 96 (1990)
April 28: 93 (1957)
April 29: 94 (1974)
April 30: 93 (1974)
So if Richmond reaches 89 or 90 degrees on Saturday and Sunday, that will still be a good five degrees shy of the standing record highs for those dates. It has also only been a couple of years since we have had such a warm April day like what we are expecting this weekend. The last time April temperatures broke 90 degrees was April 25, 2007 with a high of 90. Last year, the hottest April day was April 18, 2008 with a high of 87 degrees. And just in case you’re wondering, the hottest it has ever gotten in Richmond in April is 96 degrees. --Carrie
Few Lingering Showers Early Thursday AM
Skies will become clear through the day, and a ridge of high pressure will begin to build into our region Friday. This will lead to an extended period of very warm temperatures, especially this weekend! Highs will climb into the upper 80's and low 90's across Central Virginia Saturday and Sunday.

Severe Weather Wrap-up
Possible Tornadoes:
5 miles W of Smithfield
Isle of Wight near the town of Moonlight
Funnel cloud spotted in the Prince George area, but no touchdown.
Hail reports:
Golf-ball size: Fredericksburg, King George
Quarter-size: Farmville, Williamsburg, Crewe
Nickel-size: Hayes, Colonial Heights
(Full list of storm reports here)
There were numerous tornado warnings Monday, but large hail and straight-line wind damage were the main results of the severe thunderstorms that moved through central Virginia. A few showers and isolated thunderstorms will be possible Tuesday afternoon, but not on the scale of Monday's storms.
Here are some of the rain totals received storm total, from the first round of rain Monday morning, and then from the thunderstorms in the afternoon and evening.
Louisa 1.5"
Locust Grove 1.3"
Fredericksburg 1.3"

Sunday, April 19, 2009
Severe Potential Tomorrow
Hit-and-miss showers will be possible on Monday with a chance for strong thunderstorms in the afternoon and evening. During this time, the atmosphere will become unstable:
Also, there will be strong convergence at the surface:
Lastly, jet stream winds will also be strong enough to produce speed shear:
For these reasons, severe storms will be possible.
The big question heading into tomorrow: how unstable will the atmosphere become? If we see a little sunshine, then the chances for severe storms will increase. If we're socked in clouds and rain all day, then the chances decrease.
Saturday, April 18, 2009
Where Are The Warm Days?
I bring this up because the latest data is hinting at a major warm up headed this way in about a week (from April 25 through 30). I wouldn't be surprised if one of these days end up on top of the five warmest list from above!

Thunderstorms?
Right now I'm looking out west at a shield of clouds headed this way, so it looks like we will see only peeks of sunshine tomorrow. I still think we will warm up enough that isolated thunderstorms will pop up.
Best chance for severe storms will be in the southwest corner of the state, where jet stream winds will be stronger.

Cloudy With Sprinkles And...Flakes??
Cooler Tuesday, Spring Freeze Wednesday
It will not be unusual to have another freeze on Wednesday, April 8. In fact, April 8 is the date for the average last Spring freeze for Richmond! Could it be our last one this season? At this time, I do not see another deep cold plunge moving into our region in the next couple of weeks. However, Spring freezes have occurred as late as May 11 in Richmond (that one occurred in 1966).
Just in case you're wondering, the earliest last Spring freeze on record for Richmond is March 12, 1946. Our most recent freeze this year in Richmond was on March 25, when we had a low temperature of 28 degrees.

Chance For Storms Monday
Any storms that develop will be moving FAST, so damaging winds will be the main threat tomorrow. Carrie will be monitoring the situation in the morning and will have updates as conditions warrant. Stay with CBS 6, we'll keep you ahead of the storm!
Brush Fires
Winds will strengthen tonight, but at the same time, humidity levels will rise. Overall, this will decrease the fire danger as the night progresses.
Be sure to tune in tonight at 6:30 and 11 PM, we will have updates on the brush fires!

A Glance Back & A Peek Ahead
However, over the past seven days, temperatures have been slightly above average.
In other words, there haven't been too many large fluctuations in temperatures - no record highs and no record lows. It looks like this trend will continue for the next couple weeks. With exception to the cold blast next Tuesday and Wednesday, temperatures will typically stay within 5 to 10 degrees of the average (above or below).
In addition, the jet stream will remain rather flat, allowing fast-moving storm systems to pass the area.
This means we will have several chances for rain, which is great news! More than likely we will see average or slightly above average rainfall.

The Sun Is Giving Us The Silent Treatment
(Above: The sunspot cycle from 1995 to the present. The jagged curve traces actual sunspot counts. Smooth curves are fits to the data and one forecaster's predictions of future activity. Credit: David Hathaway, NASA/MSFC.)
The Sun has a regular cycle it goes through about every eleven years, with a predictable, steady rise and fall in solar activity (i.e., sunspots, irradiance, magnetic energy emission). And most NASA scientists thought 2008 was rock bottom for this solar cycle’s minimum. No sunspots occurred 73% of the days in 2008 (that’s 266 days out of 366). Only 1913 had more spotless days at 311 blank sun days.
But well into 2009, the Sun continues to give us the silent treatment, with an overwhelming majority of the days this year being blank. Year-to-date, the Sun has been “silent” 80 out of 92 days. Although the Sun continues to adhere to its traditional solar cycle, this minimum may be especially unusual because it is also accompanied by a 50-year low in solar wind pressure, a 12-year low in solar irradiance, and a 55-year low in solar radio emissions, according to NASA data. For more on those three points, check out NASA’s discussion here.
So if the Sun is in a minimum of activity, does this mean we don't need to worry about the sunscreen this Summer? NO! Slather on that good, protective sunscreen! Take it from someone who knows...a fair-skinned redhead with blue eyes. Yes, you guessed it, it takes me all of 10 minutes to turn from white to lobster red in the sun without protection. Wear sunscreen! Just do it. Seriously.

March Rainfall Summary
Central Virginia’s March fit the cliché of “in like a lion and out like a lamb.” A snowstorm with up to a foot of snow in parts of Central Virginia blew through March 1-2, 2009. The final days of March were fairly uneventful, remaining dry and warming into the 60’s and 70’s. However, we made good progress this month on picking up some rainfall, especially toward the end of the month. Here are some of the March rainfall totals from the area:
Richmond Intl Airport: 4.26” in March (that's +0.17” departure from average for the month). However, Richmond is still 4.13” below average year-to-date, with a total 6.49” of liquid precipitation. And, despite the impressive snowstorm the beginning of this month, Richmond is still 5.8” below average for this season’s snowfall. So far this Winter season, we accumulated only 6.6” officially, 6.3” of which fell in March. You can view March daily weather data here.
Norfolk: 5.28” in March (+1.20” depature from average for the month), with 8.36” year-to-date (-2.99” departure from average for the year-to-date)
Petersburg: 4.09” in March, with 10.62” year-to-date
Wakefield: 5.87” in March
Farmville: 1.84” in March
Emporia: 2.11” in March
Danville: 3.37” in March
Williamsburg: 2.00” in March
Fredericksburg: 0.84” in March
Charlottesville: 2.28” in March
Roanoke: 3.47” in March
Weather Watcher Reports:
Reedville: 4.7” rain (also had 3” of snow) in March
Newland: 4.4” rain in March
Coatesville: 3.28" rain in March (with year-to-date total of 5.98")
