Lenticular Clouds (lens shaped clouds) can form in the crest of the mountain waves if the air is moist. Roll Clouds can also occur in the rotors below the waves if the air is moist. These clouds are a good indication of the presence of mountain waves but, if the air is dry, there may not be any cloud to see.
Statute of Limitations. The statute of limitations for taxpayers to receive refunds is three years from the date the return was filed or two years from the date any tax was paid for the tax year in question. This doesn&amp;rsquo;t preclude you from filing a return.
You must file your tax return to claim a refund within three years of the tax due date, which is typically April 15. If you fail to file your tax return within the three-year limit, you will lose any credits, including overpayments from income tax withholdings and prepayments through estimated tax payments.
