Here is your forecast

Forecast concerns today...Showers and thunderstorms...With a outside chance of an ISO severe storm....Temps still remaining cold through this week,into the early next week...So the below normal temps continue....Off and on showers and thunderstorms through the rest of the work week into the weekend.....Don't think it will be enough to really help out the drought conditions....

CURRENT CONDITIONS.....

SFC OBS showing temps in the lower to middle 60s across the FA....Dewpoint temps in the middle 50s..Winds out of the South/Southeast around 5 to 8 MPH...Radar showing a rather large area of showers and ISO thunderstorms at the 8 am hr....So if you are in an area that has not seen rain this morning...Hang on it's on it's way....



SFC ANALYSIS...

This morning's weather charts still appear to fallish...A CLD FNT slices through MN this morning...Meantime a 1005 MB low pressure system over Northern OK/Southern KS....1020 MB high pressure is found over Western Canada reaching down into the Central Rockies.......

TODAY THROUGH TONIGHT....

CLD FNT is forecasted to slowly work towards the FA...This has already produce some light rain showers over night....This will keep showers and some thunderstorms ongoing through out the day...INSTBY is rather low today however combine INSTBY along with CAPE values around 800 to 1000 J/KG...Not really much in the way of wind shear....However very cold air sitting upstairs....May see a few hailers around later this afternoon...Mainly in my Southern FA...This will mainly depend on if we can get some SFC heating going..CLD FNT washes out right over head becomes more throfish in nature..Will keep some showers and thunderstorms going for tonight. QPF is FCSTD to be around 0.25 to as much as 0.50 in thunderstorms......Highs today middle 70s South...Lower 70s Central and Northern areas.....Winds S/SE around 5 to 8 MPH...Lows tonight Lower 50s North..Middle 50s Central and Southern areas...

WEDNESDAY THROUGH SATURDAY....

Trofs/Shortwaves shall be impacting the FA through this time frame....This will give us a chance of showers and thunderstorms about every day...Small chances though...Better chances come in about Friday night into Saturday......Temps through this period....Upper 70s to around 80 Southern areas...Central areas should see temps in the middle to upper 70s...My Northern areas should see temps in the middle 70s ....Lows mainly in the Low to middle 50s North...Middle to upper 50s Central...Upper 50s to around 60 in my Southern areas...This time frame by all means won't be a total washout....

LONG TERM...(JULY 26 THROUGH AUG 6)....

Temps do start this long term below norms...No big surprise there....However temps do become warmer... Around Aug 1st...Should be in the middle to upper 80s...Not warm enough for you? No problem by Aug 4th we should see temps in the upper 80s to lower 90s...Should hold right through Aug 5/6 time frame.....As far as showers and thunderstorms go.....Overall looks to be a dry period still...Sure there will be a chance of showers and thunderstorms through out this time frame.....To sum it up this time frame...Temps slowly warm up to above norms...The dry pattern holds strong to the FCST area...See Drought Conditions in my last forecast from last Friday......
