Not accurate for 2018 for sure

Think this forecast is incorrect for north Texas. Had an over abundance of rain in February and the rest of the time we've been below average for rainfall. Maybe the precipitation and temperature graph bars needs to be flipped the other direction for above normal temps and below normal rainfall...

Wrong Precipitation by a lot for February 2018

We had so much rain in February - normal is 3", we had 9" in Denton, Texas. Other than that, I was told that El Nino will be predominant from August on, so we expect more rail to come our way.

Wedding

Hello, I was wondering if I could get an estimate on the forecast in Southwestern Oklahoma on October 20, 2018. I am planning an outdoor wedding and I want to plan for everything... but I am on a tight budget so if I could get a better educated guess than a "maybe" I would greatly appreciated it. Maybe a percentage as of right now the likelihood of us getting any precipitation?

Thank you for your time and assistance; I look forward to hearing from you.

Long range forecast for TX OK

FA was spot on for Austin San Antonio metroplex. We had a colder than the "new normal" winter with snow that didn't melt as it hit the ground. Cooler than average for spring. Planted my garden later than usual and plants are doing fine. But this week we had triple digit heat we don't typically have this early.

Forecast completely wrong

For Odessa Texas the forecast was completely wrong. It was a warm dry winter and has been hot and dry since then. Have had less than an inch of rain for the year. It’s been over 100 for days now Any way for an update forecast.

Missed it by a Mile

Here in north-Central Texas the FA has missed the temps by far. Suppose to hit the 100's today and will stay over that for the next week. Would love to have the 'above average' rainfall... would love to have rainfall!

Abnormally Hot

Here in RGV the temperatures have reached more than 100 for almost two weeks. Seems like Summer could't wait any longer and just took its place. I just hope this isn't a glimpse of how hellish the following months will be.

Dryer than normal

Farmers almanac didn't get it right for my area, which is Southeast Texas... We've had dryer than normal precip and no rain in the forecast.. Hotter than normal Temps all next week. Hope we don't have another drought like in 2011

Weather

Ever think it could be all the "clean air" we have now causing these hot summers? No smog left to filter out the sun lol.

Long range

Here in San Antonio we had a great snow during our short winter. Very wet April and cool. May 2018 has been basically dry, windy, and next 8 days are forecast to be 100+! Whew! Moved here from Virginia mountains 1.5 years ago. Used to love gardening there but gracious, its been a trial here. Growers need to adjust their shipping times for mail order delivery to this area! By the time it arrives, it is so hot the poor baby plants struggle, even those indicated for this zone.
