the week ahead

May 31, 2009

triva question: how strong were the winds with the commanche tornado in Iowa?  hint: look at the fujita scale

1. monday and tuesday will see lots of sun and a little summer preview with highs well into the 80’s and sunny skies with a southerly flow humidity will also increase as well by late tuesday.

2. wednesday the next front will move in with another storm chance looks about 50 or 60% now. due to clouds and rain highs will only make the upper 70’s.

3. thursday and friday will feature the front in the region, the question is does it stall over us or south of us? right now the euro has us dry the gfs wet and the cmc with a slight storm chance. highs will be near 80 with a cooler dryer airmass trying to move in.

weather trvia answer:  300 mph

cheers and jeers

May 29, 2009

1. cheers to today warm sunny and less hunidity as high pressure is in place with highs in the mid to upper 70’s.

2. jeers to a week frontal boundry sliding into the upper ohio valley tommorow with a complex of storms forming along it by late morning and moving in for the afternoon. this complex will produce storms will gusty winds, small hail and more very hvy rains. severe weather and localized flooding will be issues again.  highs will be near 80.

looks a bit higher than 20% chance to me which is what most forecasts have. this is the 12z guidence which has really amped up storm chances. the 12z gfs has a nice coverage of afternoon storms as well.

the spc has a slight risk for severe weather for the region on saturday

severe punch to today’s action

May 28, 2009

with the front getting closer to the region there’s a threat for more organized activty today from the ouflow boundries of yesturday’s storms and favorbakle dynamics ahead of the front. these storms should have more bark in a few spots with small hail as cooler air moves in aloft and of course local gusty winds. the SPC has issued a MD for our area.

mesonet update

May 26, 2009

often i use data from the KY mesonet for current weather conditions and to analyze weather of the previous day. I think this is a great service for the state of Kentucky.

from the nws lmk  site

The Grayson County mesonet site near Leitchfield. This site is one of 25 operational sites around the commonwealth that collect real time temperature, precipitation, humidity, solar radiation, and wind data. The newest site in the network near Harrodsburg in Mercer County, will come on line this week. There are plans for the construction of 100 sites in all. For more information about the Kentucky Mesonet, and to view data from the sites, visit the Kentucky Mesonet web site ( off to the side link)

Dr’s Foster and Mahmood who i will have the pleasure of learning from and working with in the fall were on site for this event. pictures are on nws site.

 

to the weather

1.Wednesday will feature more of the same with scattered afternoon storms with hvy downpours, i still expect about 50-60% storm coverage and highs around 80. there may be a little more coverage thanks to more upper air disturbances and outflow boundaries we won’t know the locations till about 1 or so.

2. Thursday will see fewer storms as the boundary to our north and the old tropical low  finally begin to move east highs will be near 80 again.

3. can Friday be rain free???  maybe but not a big chance for rain, it will depend on if the system lingers even longer. highs will fall into the 70’s with a dryer airmass as well by the weekend.
