Streak of above normal temperatures continues
Saturday marks the 14th consecutive day with above normal temperatures in Lincoln. This is the longest streak of above normal days since January. Even with a cold front passing early Sunday morning the streak will continue as we start a new week.
The above mentioned cold front will pass through southeast Nebraska early Sunday morning. You’ll notice the front passes when your wind turns out of the west-northwest. Don’t expect a big drop in temperatures behind the front. Cooler air will lag several hours behind the front, and even what arrives won’t be that noticeable.
High temperatures will be in the lower to middle 70°s Sunday afternoon. Winds will likely gust 25 to 30 mph, especially during the morning.
Eyes are trained on an upper-level low that will develop over the Rocky Mountains. The low will eject out of the Rockies Tuesday night/Wednesday morning. Ahead of the low, temperatures will stay well above normal for the central Plains and Mississippi River Valley.
A line of thunderstorms is expected to develop late Tuesday night. They will cross Nebraska, arriving in to southeast Nebraska Wednesday morning. The line will have potential of producing heavy downpours and strong winds. Once the line passes, drier air will quickly usher in and help clear out clouds. This will allow for a period of sunshine Wednesday afternoon.
Cooler air will move in for the end of the week making it feel more like fall.
