Above normal temperatures
Highs:  around 64-66 degrees.  | Normal highs for this time of the year are around 56 degrees.
Wind: Southerly at 10-15 mph
Precipitation probability - 40% early in the afternoon and 70% later in the day  Rainfall totals:   0.25" or less 
Confidence in this forecast is very high

.

There is a small risk for a few severe thunderstorms this evening and tonight - mainly over southeast Missouri into Arkansas - more uncertain as you go a tad east of there.  Monitor NOAA Weather Radio and local media for any changes.

.
There will be quite a bit of instability on Monday morning and afternoon - but I am a bit more uncertain as to whether storms will pop during the time of best instability.  I am going to keep an eye on that time frame, as well.


.
Most likely no - but monitor for any changes later today - monitor for some lightning on Sunday late in the day into Monday.


Will monitor the chance for a few strong/severe thunderstorms over our southern counties on Sunday night late into Monday morning.  Then again on Monday afternoon.

No significant snow in this short range forecast...

HEADLINE: 
SPRING FORWARD tonight - move your clocks ahead one hour and change the batteries in your weather radios!
.
A nice Saturday across our region - quite a bit of sun and temperatures were not too bad.  They did start out a bit on the cold side during the morning hours.  But - with the March sun we saw temperatures rise into the 60s during the afternoon.  Can't complain about that.
.
Our next storm system is already on the weather map - it will push into our region on Sunday afternoon and Sunday night.  This storm system will bring a chance for showers and thunderstorms back into the region.
.
Here is the water vapor image - you can see the system developing to our southwest
.

.
Chances for rain will begin by Sunday afternoon over our western counties and then spread east during the mid and late afternoon hours.  Showers and rumbles of thunder will be likely across our region by Sunday night. 
.
The Storm Prediction Center has outlined a slight risk area for parts of the region on Sunday evening into Sunday night.  Large hail and damaging winds would be the main concern - although an isolated tornado can't be 100% ruled out.  Monitor for any updates - this does not look like an organized outbreak of severe weather - more of a scattered type event - especially over Missouri and Arkansas.
.
There is a lot of instability on Monday, as well - but more uncertain on lift.  I will need to monitor Monday for a few severe storms, as well - CAPE values are over 1000-2000 in the region.  That is sufficient for instability.
.
Right now rainfall amounts are not forecast to be particularly heavy.  It appears the atmosphere will be stable enough for thunderstorms to remain below severe levels.
.
Rainfall totals will likely be in the 0.25-0.75" range from Sunday afternoon into Monday.  Of course there could be some locally heavier totals - especially where thunderstorms occur.
.
The atmosphere will be a bit more unstable next week.  I can't 100% out a few severe storms around Wednesday or Thursday - however, this is a bit beyond the range where we like to zero in on the potential.  Monitor for updates.
.
See the extended discussion for a bit more detail on the week ahead.
.
Monday will bring 70s across our region!  Warm temperatures.  Warm weather will likely continue into all of next week.
.
Here are the temperature departures for the upcoming week - these maps show you how much ABOVE normal temperatures are expected to be.  Quite warm this week!  Normal highs for this time of the year are typically in the middle 50s.  We will be in the 70s during the upcoming week.
.
The first image is for Sunday - then Monday - Tuesday......

Date Range: March 4th-March 14th
Event: A few shots at precipitation - severe weather risk appears low (not zero but low).
Severe Risk:  low
Frozen Precipitation Risk: Uncertain - most likely some rain events
Details: A few systems to monitor - right now it appears the severe weather risk is low.
Confidence in my forecast:  Medium .

.
.
Date Range: March 14th-31st
Event: 3-5 systems to monitor.
Severe Risk:  Can't rule out some heavier weather the last half of the month. 
Frozen Precipitation Risk: Uncertain - most likely some rain events
Details:
Confidence in my forecast:  Medium .
 
.
.
.
Remember that as a general policy, in the long range outlook, I will NOT mention severe thunderstorms more than 72 hours in advance.  I will mention thunderstorm risks and I will give as many details as possible.  The word severe will be reserved for the short range forecast.

-----------------------------  
.
1.   The long range forecast will be made up of above normal temperatures (surprise surprise).  Seems to be the norm over the last few months.  The majority of days have been above normal in the temperature department.
.
There will be a chance for showers and thunderstorms next week, as well.  On and off chances.  A few heavy thunderstorms can't be ruled out.  Will monitor - the atmosphere will be warm and a bit unstable.  The chance for an organized severe weather outbreak appears very very small (Monday through Friday)
.
A stronger storm system may impact the region around March 18th-21st.  Long way off - plenty of time to monitor and update the forecast.  
.
Here is the latest six to ten and eight to fourteen day temperature outlooks.  WARM WARM WARM!
.

.


Now is a GREAT time to buy a NOAA All Hazards Weather Radio.  Better to have one before storms strike than to be without one during an event.  I recommend the Midland Model 300 NOAA All Hazards Weather Radio - that is what I use here at my house!
