MSU Storm Chase Class

Monday, June 29, 2009

After our 7 (nearly 10) day run of ninties last week, it looks like the forecast will be void of nineties for perhaps the next seven days! Northerly winds on Tuesday should help to keep both the temperatures and humidity in check through Wednesday.

Then, a front sets up which will start generating more clouds and eventually thunderstorms starting Thursday and lasting through Saturday. This does mean that storms will threaten the fourth of July weekend!

A BREAK FROM THE HEAT

It is 6-12 degrees cooler this afternoon than compared to yesterday. The best part is that dew point temperatures continue to drop. Yesterday the dew points were in the 70's, which is oppressive and today they continue to drop into the 50s, which is comfortable.
The weather pattern this week is different than the weather patten we had last week. The ridge of high pressure will be across the west and we'll be under a northwest flow aloft. We'll have to keep an eye on disturbances tracking up and over the ridge and then riding southeastward across the Midwest this week. The first is forecast to impact the Ozarks on Thursday and the second is forecast to move in on Independence Day. The exact timing and location is still unknown at this time. As of today, it appears the disturbances will track southeastward and impact SW MO and NW AR on both days.

THE HEAT WAVE IS ABOUT TO COME TO AN END!!!

A heat advisory is in effect until 10pm. Afternoon highs will range from the middle and upper 90s. The heat index will range from 105 to 110 degrees. Being outside in this kind of heat can create a situation where heat related illnesses are possible. Drink plenty of fluids, stay inside where it's air conditioned and avoid the sun. The heat wave comes to an end tomorrow!!!
A cold front approaching from the northwest will trigger showers and storms to develop along and ahead of it this afternoon. Some of the storms could become severe and that's why the Storm Prediction Center has areas along and to the northwest of I-44 under a slight risk for severe storms. The primary threats are 60 mph winds, hail up to the size of quarters and heavy rainfall that could lead to flash flooding.

The chance for storms will increase to the northwest of I-44 anytime after dark. The greatest chance will be towards 1am from Nevada to Osage Beach. It may take until after 1am to 4am for the activity to reach counties along the interestate and points south. Rain chances will exit by Sunday morning.

Not everyone is guarenteed to receive rain but everyone will experience a drop in humidity and temperatures. It will go from feeling oppressive outside today to feeling comfortable by tomorrow. The comfy weather is expected to last through much of this week. We'll begin July with normal temperatures. The next chance for rain after tonight will be on Thursday and again on the 4th of July.

Severe Weather Shots


More scattered storms are possible today and like the previous two days, some of these storms will collapse and producing very localized damaging winds and rainfall totals exceeded two inches. The threat for a tornado is very low with this activity.


On Saturday, more storms are expected along a cool front. The front will be able to force the situation better and the upper level winds should be stronger so the storms have a better chance of becoming supercells on this day.

SUMMER OFFICIALLY BEGINS ON SUNDAY

SUMMER BEGINS AT 12:45 AM CDT


The solstice is an astronomical event that takes place twice a year, when the tilt of the Earth's axis is most inclined toward or away from the Sun, causing the Sun's apparent position in the sky to reach its northernmost or southernmost extreme. The summer solstice marks the longest day of the year and the first day of summer. There are 24 hours of daylight north of the Arctic Circle and 24 hours of darkness south of the Artarctic Circle. We receive more direct rays of sun during the summer.

The earth spins around its axis and the axis is tilted somewhat off the plane of the earth's revolution around the Sun. The tilt of the axis is 23.5 degrees and because of this tilt we get to enjoy four seasons. When the axis tilts towards the Sun, as it does between now and September, it is summer in the northern hemisphere but winter in the southern hemisphere.

FATHER'S DAY FORECAST


Afternoon pop up showers and storms cannot be ruled out on Father's Day. More organized storms are forecast to develop across northeastern Missouri into Iowa and Illinois and some could be severe. The majority of Father's Day will be hot, humid and dry across the Ozarks. Afternoon fair weather clouds will likely develop. In the morning, temperatures will start off in the lower 70s and rise to the lower 90s during the afternoon hours. It will feel hotter than the actual air temperature due to high humidity sticking around. Happy Father's Day!
