Some More Severe Weather Today: 6/28

28 06 2010

The last large severe weather outbreak for a while will plague the area today as a strong cold front plows east. Following this cold front temperatures will plummet into the 70s (can you believe it!). But today, highs will reach the mid to upper 90s with an Exessive Heat Warning issued for the entire coverage area. Because the temperatures are so high, this front will spark thunderstorms with many, many lightning strikes. With these storms the main threat will be the lightning and wind, unlike some of the previous storms which hail and tornadoes associated with them.

The storms will move through later this afternoon and a Severe Thunderstorm Watch will probably be issued.

Here are two images of the simulated radar for later today. Note that most people will get some much needed rain, but only the “lucky” areas will get thunderstorms:

Tropical Storm Alex Forms in Caribbean

26 06 2010

Well everyone, we have our first tropical storm of the 2010 season. This storm has been trudging through the Caribbean for a little over a week now, finally gaining steam and becoming Tropical Storm Alex. Because the storm formed so late and so close to land (Yucatan Penninsula), its strength isn’t expected to exceed a Tropical Storm. As of right now, Alex has no intentions of affecting the Philaburbia Coverage area anytime soon. I will keep you posted on the development of Alex as the week progresses and how (if at all) it affects our area!

Coming up later today or tomorrow morning: MORE SEVER WEATHER COMING!





6/24: Very Strong Storms Approaching

24 06 2010

Update 12:30 PM: Okay, right after I published the last post, the NWS posted a Severe Thunderstorm Watch for the entire area until 8:00 PM. Expect the worst of the storms to pass through the area around 3-5 PM.

Here is the WRF simulated radar this afternoon; the storms will be scattered, but when they hit they will be severe:

Simulated Radar for 6/24

As highs today reach the mid 90s, strong storms are forming in Central Pennsylvania right now. There is a Severe Thunderstorm Watch for that area right now, which will most likely be issued for our area by the mid-afternoon. The SPC placed the coverage area in a slight risk for severe weather and we are still under an excessive heat watch. The main threat for the thunderstorms today will be high, destructive winds. I wouldn’t rule out a few tornadoes popping up in places later today either. I will keep you updated throughout the day as these storms progress eastward.

6/22: Severe Weather and Heat

22 06 2010

The beginning of summer enters with a bang as we face our second heat wave of the year. Temperatures have reached the 90s the past three days and will continue to rise as the weak progresses. The NWS issued a Excessive Heat Warning earlier for Wednesday as heat indices will reach 100 degrees. There is also a Severe Thunderstorm Watch for the entire area until 9:00. Right now the worst of the thunderstorms are hitting Chester County and Northern Delaware.

Worst Storms Hitting Chester as of 6:00 PM:

The chance of strong storms will continue as this line moves through the area. Remember, if you hear thunder go inside immediately!

Chance of Severe Weather Today: June 16th

16 06 2010

Update: 8:00 Wednesday Night

Some average thunderstorms are moving through Central Pennsylvania right now as the frontal boundary moves west. Right now, I doubt that the storms will endure the night. The weather will become sunny and hot as the week progresses with the next chance of storms coming Sunday or Monday.

In hurricane news… Invest 92L has dissipated after a brief period of panic from some meteorologic experts. The NHC placed this tropical system as “very favorable” for development earlier this week. Right now, the system is hitting shear and will eventually break up in the eastern Caribbean. The link for the NHC is here: http://www.nhc.noaa.gov/

Hello everyone! Haven’t posted anything in a while…. Had to let school wind down and rest my brain. \

My main topic for today is the severe weather ready to attack our western coverage area today. A weak cold front (called a frontal boundery) is right now brewing in western Pennsylvania. The Storm Prediction Center originally had the severe weather area to the south of us, but suddenly moved it north late last night.

Here are some maps to help understand:

This map below is the WRF-NMM simulated radar that the computers thought up earlier this morning. As you can see, there will most likely be a line ranging from Chester county up to Bucks county wit another line following to the west. My concern is that the western line will turn severe as an effect of the sunlight and evaporation after the first line moves through.

Radar for later today

The next map is just the SPC’s severe thunderstorm probablility for later today. I will update any changes that ensue as the day progresses, so keep watch!

Severe Wind Probability

Remember to keep an eye on the skies later this morning and afternoon. If a thunderstorm comes through, go inside!
