THE FANTASTIC WEATHER CONTINUES THROUGH THE WEEKEND… ANOTHER HEATWAVE IS EXPECTED BY THE MIDDLE OF NEXT WEEK… RAIN CHANCES REMAIN LOW THROUGH MONDAY

The weather here in Hampton Roads the past couple of days has been absolutely incredible considering that this is mid-July. Low humidity, abundant sunshine, a nice breeze made it great for sight seeing, working outdoors, etc, etc. How long can this last at this time of year? Well, although temperatures and humidity levels will be inching up over the weekend, it will not be that bad. The high pressure that has been responsible for the great weather will be moving offshore. This will set the stage for what could be a major heatwave for the Mid-Atlantic States next week. But before we get to that, let’s enjoy the weekend.

What about rain chances? The next several days look dry for the most part. We may see an isolated shower/storm on Tuesday.

Although humidity levels have been low, once we get to mid-summer, a wind off the water will tend to pick up more water vapor due to the higher water temperatures. That’s one of the main reasons why August is the most humid month on average.  See my weather fact on this subject.

That’s it for now. Have a great day and thanks for reading. I’ll have an update on Sunday.

HIGH PRESSURE GUARANTEES SUNNY SKIES ON SUNDAY… THE HIGH WILL SLOWLY MOVE OFF THE COAST ON MONDAY AND TUESDAY CAUSING OUR WINDS TO SWING AROUND TO THE SOUTHWEST… THIS WILL BRING BACK THE HEAT AND HIGHER HUMIDITY LEVELS

Sunday will be an ideal summer’s day with plentiful sunshine, light winds and just about no chance of rain here in Southeastern Virginia. Humidity levels by summer standards are tolerable. Don’t get used to this weather as it will be changing over the next few days. The high pressure area that is causing the nice weather will be slowly moving off the coast. As winds blow clockwise around high pressure areas in the northern hemisphere, our winds will swing around to the south and eventually southwest as the high moves east of our area. A southwest wind at this time of year usually brings in hot and humid conditions and that is what we will see by Tuesday. What about thunderstorms? Well, there will be a slight chance of storms on Tuesday and a better chance of storms on Wednesday as a cold front approaches the region.

I haven’t mentioned the tropics lately and that is because there really isn’t anything of concern in the Atlantic basin. That is normal for early to mid-July. Hurricane season normally ramps up by the middle of August. This is the time when you should have your plan in place and ensure that you have the needed basic supplies should a storm threaten this area.

That’s it for now. Have a great day and thanks for reading.

AFTER A DAMP START, THE WEEKEND ACTUALLY LOOKS LIKE IT WILL BE FAIRLY NICE… TEMPERATURES WILL BE SEASONAL WITH LOWER HUMIDITY LEVELS… THINGS HEAT UP AGAIN AS WE HEAD TOWARDS TUESDAY

Over four (4) inches of rain has fallen in my Virginia Beach neighborhood since the 4th of July. It’s amazing what a stalled out frontal boundary and high humidity levels can do to help alleviate a drought. Some parts of the local area picked up higher rainfall amounts and some less fortunate areas picked up less,  but overall, this was the most widespread heavy rain that we’ve seen in a very long time.

A cold front has just moved through Hampton Roads and is dropping southward into North Carolina. Light northerly breezes behind the front will become easterly bringing in cooler air and lower humidity levels for the remainder of the weekend. The cloudy skies this morning should slowly give way to mostly sunny skies this afternoon. Sunday looks great with highs in the upper 80’s. As the high pressure area moves off the coast early in the work week, our winds will swing around to the south and southwest bringing back the warmth and humidity. We should be back in the 90’s on Tuesday. Another cold front should bring some relief by mid-week and may be preceded by some showers or thunderstorms.

Thanks for reading and have a great day.

THE UNSETTLED WEATHER PATTERN SHOULD CONTINUE THROUGH SATURDAY… CLOUDS SHOULD KEEP TEMPERATURES FROM RISING TOO HIGH BUT IT WILL FEEL QUITE MUGGY DUE TO HIGH LEVELS OF HUMIDITY

The unsettled weather pattern began on the 4th of July and it started out with a bang in my neighborhood. I’m not talking about fireworks. I’m referring to very heavy thunderstorms that dumped over an inch of rain in my backyard. It has been a very long time since I received an inch of rain in one day. The lightning was very intense causing power outages across parts of Hampton Roads. On Tuesday, I received another third of an inch from an isolated thunderstorm that also produced intense lightning. The unsettled weather is a result of a stationary frontal boundary and disturbances moving across the region. This is expected to continue through Saturday. It will not rain all the time but heavy rain and/or thunderstorms can occur at any time. Most of the activity will probably occur during the afternoon and evening. The boundary will drift north and south throughout the period. Will we make up for the huge rainfall deficit? It’s hard to say but at least it should be a good dent in the drought. That’s it for now. Thanks for reading and have a great day.

THE HEAT AND HUMIDITY CONTINUE FOR THE 4TH OF JULY… FORECASTERS ARE STILL SAYING THAT THERE IS A CHANCE OF SHOWERS AND THUNDERSTORMS LATE IN THE AFTERNOON AND THIS EVENING… WITH A WEAK FRONTAL BOUNDARY NEARBY, THE CHANCE OF STORMS CONTINUES INTO THE WORK WEEK

The 4th of July will feature a continuation of the heat and humidity that we saw on Sunday. The frontal boundary, although weak and diffuse is well to our north. Forecasters had originally thought that this frontal boundary would be closer to us by now, and that is why we did not see the storms on Sunday that was originally predicted. Some areas did see a storm or two but they were mostly in our northern areas. With a shortwave heading into the area later today and this evening, forecasters are still predicting that we will see some thunderstorm activity and severe weather is possible in a few spots. Hopefully, the storms don’t impact the fireworks and various festivities planned for tonight but if you are going to see the fireworks, make sure you monitor your local forecast. The forecast for the next few days includes a chance of a shower/storm on each day as we will continue to deal with the frontal boundary and various disturbances coming through the area. Remember what I said in an earlier post… When you have this much heat and humidity around, you don’t need much of a trigger to produce a thunderstorm. However, instability is required in order to have thunderstorms. If the atmosphere is capped, thunderstorms will not develop. Capped means that temperatures in the upper atmosphere are warm which creates a stable atmosphere. So the bottom line is that we will see another hot and humid day with an increasing chance of storms later today or at night. I don’t think that everyone will see rain but it is possible. Have a safe and enjoyable holiday and thanks for reading.
