Watch NBC Action News HD this weekend at 8am, 5, & 10pm for the latest weather information!
I first want to start off by thanking everyone who sent along rain totals today. During the 5pm show I showed 2 graphics full of totals and will switch in some new reports tonight at 10pm. Most locations within the viewing area received between 0.50"-1.50" early Saturday morning. I will include a list of totals at the end of this blog.
Let's start off by discussing a few things to determine our rain chances for tonight. A warm front passed thru the metro area late today and dew points are now in the mid 60s with air temperatures in the 70s. With the front to our north we are now in the warm sector of this storm system. Last night the warm front was to our south and a surface low was located near the Kansas/Colorado border. This combination along with upper level energy produced a large area of showers and thunderstorms from Nebraska to Oklahoma. Those storms pushed east overnight and gave us thunderstorms early this morning. Tonight...the surface low is located over the western Dakotas. As of this writing the thunderstorm development has been greatly limited with isolated supercells in northern Oklahoma, and some thunderstorms over Nebraska. So far Kansas has stayed basically storm free. If storms are going to occur tonight we need something to develop to our west before midnight. Right now we have a small chance of showers and thunderstorms overnight.
On Sunday we will likely see our warmest and most humid day so far this year around the metro. Highs will reach the mid to upper 80s and it will be very humid. Showers and thunderstorms are possible Sunday afternoon/evening. If storms do develop some heavy rain is likely, and there is also a slight risk of severe weather for areas from around Kansas City and points north. Once again I wouldn't cancel any outdoor plans, but just have a plan 'B' ready in case rain threatens.
With a front sagging south Monday into early Tuesday this time period will represent our highest likelihood of rain in the next 7 days. Heavy rain will also be possible with this slow moving front. Here is a look at the forecast rain totals over the next several days from the NAM & GFS.
First the 18Z NAM rainfall forecast
