Saturday, June 11, 2011: Front approaching - storm chances.

Saturday, June 11, 2011



HEADLINE:  Scattered storms will be possible on Saturday and early Saturday night - then most of Sunday should be dry (I am going to leave it dry for now - even though the models show a slight chance for a few storms - we can reevaluate in tomorrow's update) and cooler! More chances of storms  late Sunday night and/or Monday.  
.
A few thunderstorms may produce severe weather on Friday night and Saturday - severe by definition means winds of 58 mph or greater  and/or hail the size of quarters or larger
.
It is not going to rain all the time and some areas may not see any rain.  Anyone underneath a thunderstorm cell can experience heavy rainfall for brief periods of time.
.
Bottom line - if you have any outdoor plans on Friday night or Saturday then check radar before you head out the door and if you hear thunder then take appropriate action.
.
One or more thunderstorm complexes may impact the area late on Sunday night into Monday night.  Will need to monitor the exact placement of the cold front.  This will have an impact on rain chances and placement of any storms that form along the front.
.
Tuesday through Thursday will bring us northwest flow events - that means more seasonable temperatures and a chance for periods of showers/thunderstorms - some with high winds.

For the most up to date severe weather outlooks - click here.

Saturday:   Thunderstorms will be possible - main concern would be hail and gusty winds - lightning. A few storms may produce severe weather - meaning winds of 58 mph or greater and/or quarter size hail or larger.  Heat index values will make it quite uncomfortable to work outside.
.

Severe weather is not anticipated at this time.
.
Sunday:   Severe weather is not anticipated at this time.
.
Sunday Night:  A few thunderstorms will be possible - late.

Monday:  A few thunderstorms will be possible.  Uncertain about the severe potential.  Check back.

Let's also take a look (the map below) at the expected heat index for tomorrow afternoon.  Remember - the heat index is what the temperature feels like to your body when the temperature and humidity are combined.

How much above normal will high temperatures be tomorrow?  A few degrees but not nearly as bad as recent weeks.  Also note that we are getting closer to the "near normal and below normal temperatures"  
.
The map below shows you the departure from normal highs (normal highs are around 79-82 degrees).  For example if the normal high is 80 degrees and the actual high is 90 degrees then we would be 10 degrees above normal. You can find this map on the web-site, as well - click here.

.
1.  Temperatures will not be nearly as warm on Sunday into the beginning of the week - we can thank a cold front for this change in the weather pattern.   Temperatures most of next week will be in the 80s - let's keep in mind that we are entering summer - although the recent warm temperatures have been a bit unusual they are not uncommon in our area.  I consider extreme heat to be 100+ and we have yet to see widespread extreme heat in our counties.  The long range outlook continues to indicate that average temperatures during the summer months will end up below normal. 

2.  The long range appears a bit more active with several northwest flow events showing up in the charts.  This means that we may see a bit more rain/thunderstorms than we have been used to over the last couple of weeks.  I don't think anyone will complain about some rain chances?  We will need to monitor these events for the possibility of severe storms - this time of the year it is not uncommon to have storm systems produce high winds and/or hail reports.  Often times these storms move in from the northwest and travel southeast.

.

There were over 180 record highs and record lows on Thursday - June 9th.  Here is the map - record high temperatures are the red dots.  Blue dots are record low temperatures.  You can view the list of records by clicking here.
