Forecast still not clear for tomorrow..

Forecast still one big headache...Though things are slowly starting to work them self's out...18z runs are little bet better than the 12z runs NAM still would like to split the MCS...The NAMSTER shifts on area to the NW up into Northern MN,while the other area shifts through South Central MN into IA...Mean while GFS has been consent with it's thinking..Though it may be to far North...While the NAMSTER would appear to far South with the Southern complex,if the MCS do split like models suggest will happen tonight...So still big questions on where the MCS will track...One thing that is for sure looking at the RH fields looks like My FA will be in the clouds right from the get go tomorrow...Tomorrow is still in question to.If severe thunderstorms can fire along the cold front....This will depend on a number of factors....1 if and how fast the clouds can break apart...2...My biggest concern still is the H7 temps even the H8 temps...Models showing a rather strong Cap taking hold of the FA...3 SFC heating...SFC heating will either help out or it will kill the severe thunderstorm threat...If we get to much this will aid in warming up the 800 to 700 MB level,which is already FCSTD to be warm....If we don't get enough I don't think storms will become SFC based...Instability looks good.....For now the best way to run with this FCST is go with a small chance at some of the late afternoon evening thunderstorms may become severe...If storms could become severe main threat would large hail..Along with areas of damaging winds...Won't severe damaging winds that some have been saying/I heard...Don't even think it will be a widespread event if it happens at all....Will drop the tornado threat for now....Still think severe thunderstorms are becoming a less and less of chance,for reasons stated above....We will see what the 00Z model runs show,along with upper level profiles....So with that I'm out of here until tomorrow morning,,,By then I sure hope things will work out in the forecast without as many headaches...
