Forecast..Still below norm temps

Forecast problems..Short term...Rain/snow chances..Middle term...Rain/snow chances and temps....Long term..Same old thing...Rain/snow chances and temps...

CURRENT CONDITIONS.....

Temps this morning starting of in the upper 20s to near 32 most areas...Radar still showing light snow through out the area.Nothing to get up in arms about..See below.Wind are rather light at this hour..Looking up stream we do find windy conditions,and these are set to move into the FA...

SFC ANALYSIS.....

This morning's weather map we find a strong 992 MB low pressure just North of the Twin Cities metro area...A occluded front sits over far Northern WI,than reaches back to the low pressure are...Meanwhile cold front that rapidly pushed through the area is now over Eastern IN and extends to the South through Far Eastern MS/Far Western AL...Another storm system sitting over WY.CO..Also we see a 997 MB low pressure over the Golf of Alaska.........

TODAY THROUGH TONIGHT.....

Low pressure will keep moving North to about the Northeast tip of MN by 18z...This will keep light snows for the most part,with a small chance of some light rain going through this morning...This should taper off as we head through the morning early afternoon...May see another 1/2 of snow from a line from Northern Barron,Polk,and Rusk Counties.. Where call to our weather observers this morning have show this is where 1/4 to half inch have already falling...Call to our Central,and Southern weather observers in said Counties above show little in the way of snow,Trace for most part to less than a 1/4 inch a radar confirms this...Better chance of seeing an inch or so will be found a line from Webster to Trego over Towards Hayward then over to Park Falls. Winds won't die off at all today Pressure tends showing we go from -.3 MB at 0900 UTC to close to +1 MB by 1800 UTC....This should keep winds ranging from 10 to 20 MPH with higher gust today...Temps today will range from the middle 30 North to upper 30s South...For tonight low pulls far enough way and takes the Flurries with it..Still will have to run with cloudy to mostly cloudy as humidity still running around 70 to 90% through out much of the FA at the 700 MB level.....Lows tonight should range from the lower 20s North to around the middle 20s South....

THURSDAY THROUGH FRIDAY....

1016 High pressure builds into the area early Thur Morning..This should set us up with a rather peaceful day..Winds will be lighter,Skies are forecasted to be partly cloudy through the FA highs on your second day of Apr will bounce back into the upper 30 North to low 40s South,...THUR night...Strong 992 MB storm system over the TN area may kick in some clouds into the Southern and maybe Central parts of the FA....Nothing to worry as that will be short lived...As 1010 MB high pressure build down from ND into the area...Low THUR night upper teens North lower 20s South.....Friday high pressure is forecasted to be over far Western MN this will keep Skies mostly sunny through out the entire FA..High rally back into the middle 40s across much of the FA....Low FRI drop back into the middle 20s....

SATURDAY THROUGH SATURDAY NIGHT....

Still rather peaceful....High pressure still in control of the areas...Skies on Sat partly cloudy...High on you first weekend of Apr shall be in the middle 40s...Sat night we see a 990 MB low pressure over KS this is forecasted to spread rain/snow back into the area later on Sat night....Low Sat night in the middle 20s.....

SUNDAY 05 THROUGH MONDAY NIGHT 06....

The 00z runs off of GFS and ECMWF...Shows the track of the storm system above more to the South that in other runs...For the most part models have been trending that over the last few runs...So with that in mind we may very well pull out percip chances in later forecast for this time period...For now will go with rain/snow for the Central and Southern FAS...While our Northern areas may not see anything at all....Highs on Sun in the upper 30 North to around 40s South...Lows Sun night in the middle 20s..Monday will hold on to the rain/snow for our Central and Southern areas...Highs on Mon upper 30s seem to be the way to run as this storm system will drag in more colder area..Low Mon night Middle 20s.....

So this whole FCST cycle above shows temps running 5 to 10 below Norms for this time of year...Will it warm up ? Lets find out by talking about the longer term FCST.....

LONGER TERM......

TUESDAY 07 THROUGH WEDNESDAY 08....

High pressure builds back in the area on Tuesday..Should be a dry period,still cold highs in the upper 30s to lower 40s....Temps still colder than norms....

THURSDAY 09 THROUGH FRI 17...

First out of the gates is precip chances.....THUR we find one storm system to out South,Also a trof moving in form the NW..This very well give us a chance at some light snow through out the FA.Thur into Thur Night...By Sunday 12...We see another system moving in from the Western States..It appear that this system will stay just to the South..May brush my Southern zones with some light precip,Meanwhile we see a clipper like system moving SE out of Canada Models keep this low over Lake Superior..We should see some rain/snow from this system Monday night into Tue the 14...That system pulls away rather fast,however right on it's heels is another system for Tue late night and Wed..With more system moving for the rest of the time frame....Ok lets see what the temps dept is up to this go around....Temps starting this time frame below norms...No shock there,Lets see if we can get them to work faster, to bring in at least temps at norms if not above...By Fri 10th temps shoot right up into the middle 40s some parts of the FA may see upper 40s...So that little kick in the butt helped..How long will it help lets find out....Sat the 11th temps into the upper 40s to middle 50s a good possibility...We do cool off back below norms once again by the 12 /13 and hold that way through the rest of the period....

So to sum up the longer term forecast...Off and on Chance of precip with a few days above norms..However the ave norms through this period will still be below norms...If this pattern hold up...The rest of Apr could be above norms, still the temps will be below norms when we end Apr...So really no end in sight to the below norm temps.....
