My Forecast

Warm weather will remain with us through the weekend and through the middle part of the upcoming work week...Then a big cool down...Rain than snow...By weeks end
Current Conditions...
Temps at this hour are ranging from the lower 20s to the lower 30s across the entire forecast area...
Winds are rather light with clear to partly cloudy skies per satellite view and SFC OBS....This has lead to some scattered areas of fog in low areas...Not that big of a deal though...
SFC Analysis...
Looking at the SFC charts we find a 1025 MB low pressure over Central IA along a cold front that reaches from Maine to said low...We also find a large 1025 MB high pressure just to our North in Canada...Meanwhile there is a strong 980 MB low pressure spinning of the Northwest Pacific Coast..What does this all spell out ? Lets find out, shall we?
Today....
Temps should be a degree or two cooler today than yesterday with high pressure up to our North,along with a few high clouds drifting in from time to time...Still rather warm for Nov....Should be a great day to get out and put the finishing touches on any yard work that remains...
Tonight through Sunday night....
WAA kicks in as a warm frontal boundary moves towards the FA...Will keep the chance of showers in the forecast tonight and tomorrow, though not really thrilled about,models do show it's the way to run..So I did for now...Sunday night warm frontal boundary move into and through much of the FA this will ensure us of a warm night and set Monday and Tuesday up for warmer temps...
Monday through Tuesday...
Monday we find our self's basking under warm partly cloudy skies...I have temps in the 50s to middle 60s through out the FA...I may have to bump them up in our Southern zones to the upper 60s to lower 70s...Shortwave/weaken cold front moves into the area Monday night into Tuesday this will set the stage for showers Monday night and Tuesday....Thinking right now is I may be able to pull showers out of the forecast,will let ride for now,and see a few more computer runs to make that call...Wednesday I did add thunderstorms to the forecast as more instability and lift move into the area...No severe thunderstorms are forecasted with this system....
Thursday through Friday....
This time frame is oh the hard side to pin down,as models have some disagreement going on..Will use GFS model for this forecast right now as it seems to have a better handle on things....Low pressure is forecasted to move out of CO towards the Northeast Towards Central MN by Thursday..By Friday said low pressure should be over the UP of MI....This shall give us a wet Thursday and Thursday night....What is hard to nail down is, will the rain change over to snow for Thursday night ?...Some of the model are pointing in that direction,however some aren't..Friday... if the rain has not changed over to snow it shall on Friday...We shall have a better handle on this as we get closer to this time frame...One thing that models are a little closer on agreement, is temps will be getting colder by weeks end...Looks like highs by Friday should be in the 30s
