<div dir="auto">Sorry for jumping in here. Perhaps set resources@cnLevelSelectionMode = "AutomaticLevels". My guess is your data is out of the range on your color bar on these days.

There are no error messages when it plots the two regions. I would say no to your second question. For example, for the same hour, the regional map shows a totally different picture but the zoomed in version is all one color. I am using the same HRRR grid to plot both regions. Could it be that I need to use a different fill type (raster vs another) since the data can be sort of non-uniform and NCL is trying to smoothly contour it?</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Sep 29, 2021 at 1:11 PM Adam Phillips <<a href="mailto:asphilli@ucar.edu" target="_blank" rel="noreferrer">asphilli@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi Andrew,<div>2 questions:</div><div>1 - Are any error messages returned when the plot with the red fill occurs?</div><div>2 - Is there a chance that the HRRR data for that particular metric and region all fits into one contour interval (as for example all the data has values say greater than 50kft, or all data falls between 5-10kft)? </div><div>Adam</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Sep 29, 2021 at 2:48 AM Andrew Kren - NOAA Federal via ncl-talk <<a href="mailto:ncl-talk@mailman.ucar.edu" target="_blank" rel="noreferrer">ncl-talk@mailman.ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi there,<div><br></div><div>I'm wondering if anyone has ever run into this issue when plotting. I am contouring HRRR cloud ceiling data on a regional and local domain of NC. For certain hours, there is one color on top of the map, such that it appears the contouring didn't work correctly. This is only found on the smaller domain and not the regional domain for the same time periods. I thought maybe this was related to me using a triangular mesh, but that wouldn't fully make sense.
